Air Cleaning Plants – Philodendron

Philodendrons are one of the easiest types of houseplants to grow. They can grow in very low light conditions and are not disturbed by neglect. If you treat them right, though, your Philodendrons will flourish for many years to come. They will also benefit your family by removing formaldehyde in high concentrations from the air of your home, according to N.A.S.A. They are native to the Tropics of the Americas and the West Indies. Philodendrons live in swamps, on rocks, or along rivers. They grow long vines with heart-shaped, green leaves. Their flowers are rare, but large and white like a lily. Temperature Philodendrons require a frost free environment. If you can provide this, they can grow in the shade outside. They thrive best in 60F-70F, but watch both night and day temperatures to satisfy this need. Night temperatures can vary widely from daytime temperatures in some locations. Indoor philodendrons can tolerate even lower temperatures, since they do not suffer frost. Light Indirect, bright light is ideal for philodendrons. Keep them from direct or intense light and they will flourish. Direct sunlight will burn the leaves and the plant’s growth will be stunted. Low light conditions will force the leaves to grow farther apart and smaller. Water The soil should be evenly moist most of the time. Avoid over watering, though, which is indicated by standing water. It is best to let the soil dry out a bit in between waterings. If they are over watered they become vulnerable to disease. Winter is a good time to reduce the water to your Philodendron. While they can get by in low humidity for a time, Philodendrons prefer high humidity. Misting your Philodendron can help keep the leaves clean, while providing some of the moisture it needs. Soil Philodendrons prefer heavily organic matter as a growth medium. That is why you may find them often growing in the bark of large trees. The soil should contain rocks in the bottom and then sand mixed with the organic material in order to drain well. Growing Philodendrons can grow quite fast. Do not count on any flowers if you are growing your Philodendron indoors. Many Philodendrons are climbers, but not all. You must know the species you are dealing with. In general, if it has waxy green, heart-shaped leaves, then it is a climber. Some send out aerial roots that can be trimmed when they look ugly or redirected to grow back into the soil. As your Philodendron is still young and growing like a weed, you should re-pot it every Spring. You can simply replace some of the top soil for older Philodendrons. The leaves accumulate dust. Clean them as often as you notice them getting dirty. Fertilizer If it is the start of the growing season, you will want to employ slow release pellets. During the rest of Spring and throughout the Summer, feed it half strength liquid fertilizer weekly. Propagation Take a cutting with two or more joints and many leaves. Make sure you get a clean cut. If you ask nicely, your local store may allow you to take your own cutting without charge. Keep the leaves above the water and the rest submerged. Use a little root hormone if you would like a better chance of succeeding. Within five weeks your Philodendron will have its own roots. Plant these 1” deep in a pot of soil and next to it place a long piece of wood for it to climb as it grows. Water it carefully for the first month or more, to keep the roots from drying out. Problems Yellow leaves can be a sign of over watering or too little light. Brown leaves that fall off is an indicator of under watering or too much heat. Curling brown leaves is telling you that you are using too much fertilizer. Pale leaves reveal that your Philodendron is not getting enough fertilizer. Brown areas indicate damage from sunburn, while black spots that the temperature has been too low. However, Philodendrons are not prone to diseases. They are quite hardy plants. They are occasionally infested with pests. Aphids, scales, mealybugs, and spider mites all love Philodendrons. If your plant has root rot, it is most likely due to soil that does not drain well enough. Add more rocks to the bottom of the pot and sand to the mixture. Do not let pets or children eat the leaves of the Philodendron, since they contain a toxin. The Final Word Philodendrons are nice looking plants that go where other plants cannot, as they climb everything they touch. Anyone can grow them and everyone will enjoy...

Air Cleaning Plants – Broadleaf Lady Palm

Broadleaf Lady Palms have been found to clean toxins from the air of your home. The main four it takes in are carbon dioxide, formaldehyde, xylene, and ammonia. Grow a few in your house and you will stay healthier. Lady Palms come from China and are some of the easiest palms to grow. They attract many kinds of tropical butterflies and can make a home to nesting birds if planted outside. Rhapis excelsa has been cultivated in Europe as far back as 1774, in America in the 1850’s. They were first grown by Japanese upper class 500 years ago. Two versions of Rhapis excelsa exist. There is a miniature version that are cultivated by Japanese specialists. The most common, however, is a large palm with broad palm fronds, grown from either seeds or division. Growing Lady Palms grow slowly, at 8 to 12 inches annually under 80% shade and subjected to subtropical temperatures. This reduces as it is grown indoors. They can reach as high as 14 feet and have palm fronds from 6 to 12 inches across. Keep the plant thinned by removing any leaves that have become discolored or dried out. This will aid in ventilation. If new growth is brown or dead, then the entire plant should be cut back to the soil. The whole plant has become rotted. Everything after that will come out rotten. If only the tips are browned, trim the tips off. Black tips indicate you have gone way too far with either water or fertilizer. Cut the tips off and adjust your watering or fertilizing. Light It can thrive in any kind of light from shade to full sunlight. The best results will likely be found in full, but indirect sunlight. The more in shade it grows, the darker green the leaves. If you move it into fuller sunlight, the leaves may turn yellow and their tips might burn. That will go away as the plant acclimates. Soil As long as the soil drains well, it can be clay, loam, or sand. Try to keep it slightly acidic. Add some organic material to it as well so it will hold some of the moisture, while allowing for good drainage. Water Do not over water. Standing water in the soil will only promote root rot. It can tolerate dry periods, but keep them short. Remember that misting it will keep the fronds clean from dust. Fertilizer This is one of those rare plants that should hardly ever be fertilized. Propagation Lady Palms require both sexed plants in order to achieve successful pollination. However, if you are set on propagating from seed, they are prepared commercially. Other species of Rhapis do not even have male and female plants and must be propagated by division. Lady Palms produce so many roots that dividing the rhizomes is not that much of a problem. You should wait to divide it until the root system has either grown to break its clay pot or has simply become root bound. Divide the roots without worry about harming the plant, since the Broadleaf Lady Palm is a hardy plant. Problems Pests that attack the Broadleaf Lady Palm are the scales and spider mites. Take care of them much as you would on any other houseplant. Pick off the scales and spray leaves with insecticidal soap. Use a cotton swap dipped in alcohol to kill mites. Lady Palm Sports There is a seedling sport that involves finding and cultivating variegated specimens from seeds. Taking a random sampling of about 10,000 seeds, about 5 may come up with leaves bearing stripes. Only 1 of these will be a sturdy enough plant to keep its stripes. It is extremely rare for the plant to give rise to young who bear the same striping. When they do, they are given names. Otherwise, the striping appears random from plant to offspring. When the offspring do bear the same striping it is that of the leaf above it where it sprouted. Variegated Lady Palms Perhaps the most popular variegated Rhapis excelsa is the Zuikonishiki. It is straight forward to grow and gives rise to many sprouts. Still, only about 40% of these sprouts are good enough to propagate. The rest tend toward either too much green or too much white. When the Rhapis excelsa tends toward white leaves, the effect is a golden color, called “golden chlorophyll”. These variegated types should be grown in cooler temperatures and average lighting. Too intense of light will burn the leaves. While increasing the fertilizer can mask the stripes, it cannot eradicate them. Keep to average fertilizing in order to bring out the correct...

Air Cleaning Plants – Peace Lily

The Peace Lily, a.k.a. White Flag or Spathiphyllum, is one of the most popular plants to grow indoors. If people only knew that it filters out 5 very dangerous toxins from the air, it would be the most popular of all. The toxins include benzene, formaldehyde, trichloroethylene, xylene, and ammonia. Light Peace Lilies grow best with strong, but indirect sunlight. About 6 to 8 feet from a window that does not allow direct sun in will do best. It is rumored that Peace Lilies can be grown under florescent light and even in a room without windows. Temperature Peace Lilies should be grown between 68F and 80F. Do not let any drafts blow on the plant. If the temperature drops to less than 45F the plant will die. Fertilizer A 20-20-20 fertilizer made for houseplants can help the Peace Lily bloom, but it must be administered at half strength and only during the Spring and Summer. During the rest of the year you should not fertilize. Water The best indicator to know when the Peace Lily is thirsty is when the leaves droop. On average, you should water your plant once per week during growing season. During Winter it requires much less water. Mist the plant regularly and if you forget to water it, do not worry. Even if you come home one day to find its leaves collapsed over the edge of the pot, try watering it and misting it. A miracle just might happen. Chlorine in the tap water can poison your Peace Lily. So either use bottled water without chlorine or let your tap water stand overnight. The chlorine will work its way out. Growth You can expect your plant to grow as much as 2 to 4 feet. There is no dormant season for your Peace Lily. Instead, it stops blooming in the Winter and requires less water. Blooming The Peace Lily blooms in the Spring and the Fall. Its blossoms last two months. If your plant is not flowering, give it more light and make sure you are feeding it fertilizer. The pollen from the stamen will get on everything. It is not impossible to get out of clothing, but not so easy either. As one blossom starts to droop, save the energy of the plant by pruning that blossom off. The energy will automatically be sent to help grow the roots and the leaves. Re-Potting If your Peace Lily is absorbing all of the water you pour on it, within only a couple of days, then it may be root bound and in need of re-potting. Other signs of being root bound include crowded roots showing through the bottom of the pot and the stalks crowding the pot. You should re-pot it at least every 1 to 2 years. Propagating The fact that Peace Lilies clean your air means that you should propagate as many of them as possible. Jam them into your dwelling space and give the extras to all of your friends and family. Use the new crowns of your plant to start a new plant. Crowns are where new groups of leaves are growing separately from the rest of the plant. To do this you have to take the whole plant out of its pot. Then determine which parts of the root mass belong to the crown that you are going to separate. Do not worry about breaking some roots. It is inevitable. Once you pot the crown in its own pot, it might wilt. It will bounce back in 1 to 2 weeks. Do not fertilize the new plant for three months. The roots are quite sensitive to burning. The full-sized plant has delicate roots and even more so for young plants. Problems Yellow leaves indicate too much light, but brown spots are burned areas where direct sunlight hit the leaves. Rumor has it that Peace Lilies are poisonous for cats and dogs. While this rumor contains some truth, the Peace Lily is not deadly for your pets. In fact, the plant contains oxalates that will upset the animal’s stomach and drive them to quit eating the plant after only one bite. Getting the oxalate from a Peace Lily on your hand could irritate the skin. This come right off when washed well with soap and hot water. If your blossoms are green, then you have given your Peace Lily too much fertilizer. Reduce it so next season the flowers turn out white. Keep pests off by cleaning the leaves regularly. The two that you might get are aphids and mealy bugs. The first is evidenced by sticky slime covering the plant. Use a...

Air Cleaning Plants – Rubber Tree Plant

The Rubber Tree (ficus elastica) is an evergreen, which in its native environment may grow to 100 feet. Yours will probably not grow more than 10 feet tall, though you can keep it pruned to fit your room. It removes formaldehyde from the air, so treat it right and it will treat you right. The sap used to be harvested in the 20th century to produce rubber. While the plants do live hundreds of years and the sappling is too immature for 7 years to be harvested, the Rubber Tree gives over 30 years of useful production for manufacturing rubber. Light Rubber Trees do not require much light, but they flourish when there is bright, indirect light. Many people put their Rubber Trees near a window where the light is filtered through a pair of sheer curtains. Less light, during the growing of leaves, will yield larger leaves. However, do not move it from a cool to a warm room or the other way around. Also, Never place it in a draft or near a source of heat. Rubber Trees do not take well to change. Water How much water you give your Rubber Tree will directly affect its health. While it is in its growing season, you should keep the soil moist. Water it deep. Although the dormant season requires you keep the Rubber Tree drier, it is possible to underwater it. Make sure you clean the leaves of your Rubber Plant to allow it to breathe easier. You should mist them occasionally. Soil The container for your Rubber Tree should be large enough to grow a 4-foot tall tree. Make sure there are drainage holes in the bottom. Place a layer of small 1-inch rocks in the bottom to aid in drainage. Add equal parts of peat moss, sand, and garden loam. This will avoid the wet, soggy conditions that Rubber Trees despise. The soil will drain quickly enough for the Rubber Tree to feel right at home. Fertilizing Fertilize your Rubber Tree during the Spring and early Summer, but not when it is dormant in the Winter. Half-strength houseplant fertilizer will do. Propagation The best approach to propagating a Rubber Tree is air layering. It is straight forward and always works well. Find a healthy, leafing part of a branch. Make a cut on the stem below that. Cut half way into the stem. Then use a toothpick soaked in root hormone solution to spear the cut sideways and hold it open. Wrap the cut in thoroughly wet sphagnum peat moss. Wrap the peat in plastic, but loosely. Make it only tight enough to keep the peat on the cut. Watch for a few weeks and you will have roots growing in the moss. Finally, cut off that stem below these roots. Plant this in a pot and you have your new tree. Pruning Cut below the thinner parts, just above the thick part of the branches. Cut right above leaf nodes. Try to prune the over all size of the plant. Everywhere you prune, new branches will spring up. Think of it as giving your Rubber Tree a haircut. Always keep one set of leaves, at least, so it can continue to make food for itself and re-grow. Problems If the leaves turn yellow and brown, then fall off, you know you are giving it way too much water. You could also have root rot, if the leaves are yellow. Remove the plant from its pot. Knock off the soil. Trim off the damaged parts of the roots and re-pot. If the leaves droop, without falling off, you know you are under watering your Rubber Tree. Increase the watering until the leaves perk up again. If any leaves fall off, you can make a nick (not deep) with a clean knife just above the node and the new leaf will grow back faster. However, be aware that the leaves at the bottom fall off naturally. Do not freak out. There is a chance that if you do not mist your Rubber Tree and its leaves become dry too long, that you might get mites or thrips. If misting again does not drive them off, try an insecticide designed for indoor plants. If your Rubber Tree gets hit with scale insects, either pick them off one-by-one or touch them with a swab soaked in alcohol. They will easily die, but they usually come in droves. The Final Word The Rubber Tree is best grown from a sapling, rather than a mature tree. The sapling will adapt to its new environment much better than a mature plant. However, it is not so...

Coco Coir for Growing Plants

Coco coir is made from the outside of the husk of the coconut. The way it is ground up and the variety of coconut used, make for the many brands found on the market. You can find coco peat too, which holds eight times its own weight in water and is made from coco coir. The nutrients in the water can then be released slowly without further watering. This is due chiefly to a higher than usual cation exchange capacity and a pH of 5.7 – 6.5. Coco peat is an environmentally friendly alternative to peat moss mining in environmentally sensitive swamps. It performs better than traditional peat and is 100% biodegradable. Plants grown with coco coir develop larger roots, blooms, and stems and coco peat does not become compacted like ordinary soil. Coco coir provides better aeration for the root systems, resulting in better growth. Soils that are degraded can be rehabilitated with coco coir. Lignin is the magic component that encourages better microbes and healthier roots. Trichoderma is one bacteria that comes with coco coir. They thrive among healthy roots and they kill fungus. Using reverse osmosis water (RO) instead of tap water targets harmful bacteria, while protecting good microbes. RO removes many impurities from tap water, including phosphate, minerals, nitrate, and heavy metals. Coco coir also maintains an ideal pH level. Use coco peat as an additive to your plant’s soil or as a substrate in the foundation. Coco coir cannot easily be compacted, because of the coarse fibers that are so tough. This spacing allows for more oxygen to the roots. Other soil mixtures do eventually settle, which coco coir does not ever suffer from. Preparation When you purchase any coco peat you should clean it and fluff it. Place the coco in many gallons of water. To speed up the process don some gloves and peel the outer parts off while in the water. Do this again once it has absorbed the water. Be sure there are no clumps left in the coco. You will need to make a strainer from some large Rubbermaid garbage container, by drilling holes in the bottom. Pour the coco into the tub and rinse three times with hot water. This will wash out the salt. Coco releases high levels of potassium (K) and phosphorous (P) quickly, but calcium (Ca) and magnesium (Mg) should be added. Coco coir takes up both Ca and Mg and holds onto them. Usage Coco coir can be over watered, contrary to popular opinion. The fact that coco coir retains water means that it may look dry on the surface, but if you monitor it beneath the surface you will see whether or not it needs watering. Adapting to the difference in water retention is one of the biggest hurdles to face when starting with coco coir. The Final Word Coco coir reduces the occurrences of disease, lowers the maintenance requirements, increases water retention, and oxygenates roots. It requires a new way of thinking about growing plants, but if used with forethought, coco coir can provide great benefits to your plants. Plant growth is optimized by coco coir holding onto nutrients and releasing them over a longer period of...

Air Cleaning Plants – Spider Plant

All plants naturally produce Oxygen from CO2 (Carbon Dioxide), but some houseplants also absorb benzene, formaldehyde, xylene, toluene, and trichloroethylene. Plants with more surface area filter toxins from the air faster. If the plant takes in the toxins before they get in your nose and lungs asthma and allergies can be reduced. Spider Plants Clean Air Polutants The Spider Plant (Chlorophytum comosum) takes the styrene, carbon monoxide, benzene, nicotine, and formaldehyde out of any 200 square foot space. Once the Spider Plant is established it is easy to maintain this natural air cleaner with little care. We can thank South Africa for the gift of the Spider Plant, a native to that country. Display Spider Plants can be plain green, green with white edges, or the same with a central white stripe. One of the best ways to display Spider Plants is by hanging them in a pot. Their leaves will sprawl over the edge with their variegated green and white patterns. While they may bloom from time to time, their tiny white flowers often go unnoticed. Light and Temperature Place them in indirect light somewhere close to a window. Keep the temperature above 60F and avoid drafts on your Spider Plant. Propagation The small stalks that pop up can be planted to grow new Spider Plants. As the baby plants form on these stalks, pin them down against soil in a small pot. You can use a toothpick. The roots will begin to grow, which is the time to cut the babies free. If you are having troubles getting the babies to live, try a little Rootone to encourage root growth. As for soil, use a quick draining soil that is aerated quite well. Water and Humidity Make sure you water your Spider Plant weekly, but never leave it soaked through and through. These are the kinds of plants that you never have to worry about missing a watering. They really do not mind going dry for a while. To maintain proper humidity, try misting it many times a week and even bringing it into the bathroom while you are showering. Cats It is true that some cats adore eating Spider Plants. Evidently, there is good reason for their popularity among felines. They act as a hallucinogenic in a similar way to catnip. Keep them away from the cats by hanging them high and away from other objects. Brown Tips Occasionally, the tips of the leaves might brown. This is typically due to either too much sunlight or insufficient humidity. It could also be due to chemicals in the water. Try switching to distilled water and this should solve the problem. Cut off the brown tips as they appear and adjust the light, humidity, or water quality. Growing Starting with the growing season you should fertilize a Spider Plant weekly to twice weekly with half strength house fertilizer. Quit the fertilizer as Winter begins. It is easy to underfeed or underwater a Spider Plant during its growing season. Spider Plants love filling their pots with roots. So you never have to worry about Spider Plants becoming root-bound. There are two complimentary sets of requirements that must be observed to grow your Spider Plant to its maximum health. Keep it out of direct sunlight but keep it in bright light. Keep the soil dry, but give the plant a lot of humidity. Problems Spider mites can be attracted to Spider Plants when the air is warm and dry. To rid your plants of these pests use insecticidal soap or horticultural oil. Repeat this after 3 or 4 days. In order to keep them at bay you might repeat a third time. Greenflies are known to chomp on the edges of the leaves. Apply insecticidal soap or pyrethrum, then do it again a couple of weeks later. Clip the leaves off at the soil, that show this damage. When a variegated version begins to turn a solid color, it simply requires a bit more sunlight. The variegation will return. Cold will turn the leaves transparent and soft. Assuming the roots have not frozen, you can clip off the damaged leaves and let it regrow. The Final Word Spider Plants really are quite simple to grow. Follow the few guidelines explained here and you will have cleaner air. Since propagation is so simple you can turn one plant into an army of Spider Plants and clean the air for your whole...

Grow English Ivy in Your Living Room

The image of a lush green plant overtaking a red brick wall, particularly of a centuries old cottage, is enough to motivate any gardener to start a fresh English ivy plant in their home. English ivy is a fantastic climber, using its tiny roots to grab any surface. It can be used to engulf anything you desire. Growing You can grow English ivy in pots or baskets as long as you have a structure for them to climb along. The supporting structure does not even have to be vertical. You can train your English ivy to grow in any direction with a little coaxing. Tie their vines to whatever structure you want them to follow and they will soon take it over, growing even up to 50 feet or longer. You must be patient, though. The first year will see very slow growth. The second year will yield more visible results. The third year the plant will grow so fast it may be hard to manage. Where other plants may fail in the house, English ivy thrives. Place it in doorways and around cooler windows, since it tolerates the cold far better than your other houseplants might. You might have an ugly wall to hide or some other blemish in your house, or on the outside, that could use the friendly covering of English ivy. You might also choose to lean on English ivy as a ground covering in places where other plants refuse to grow, but it really does look much better sprawling up the walls of buildings. English ivies love to be re-potted annually, but do it in the early Spring. Also, remember to prune them at the same time. Remove weakened parts anytime you see them. Water Growing English ivy is only difficult because they do not like the warmed air of a house, which can be quite dry. Keep their soil moist while they are establishing themselves. While they do love moist conditions, they can put up with dry periods. You can also over water them. Yellowing leaves is a sure indicator of over watering. Try to keep the soil moist from Spring through Fall. Mist your English ivy and it will love you back with lush growth. Misting an ivy will also eliminate spider mites. Aside from misting, you can raise the humidity for the English ivy by placing the pot on a tray of soaked pebbles. Fertilizer It is unlikely you will ever need fertilizer. If on the off chance you do, make sure to dilute it to half strength and use a fertilizer high in nitrogen. You can feed your English ivy as often as once a month from March through September. Soil Plant your English ivy in soil that is rich in organics. If you must, add compost to make up for what it lacks. Mix equal parts of peat moss and perlite for a well draining soil. Light They love very bright, indirect light in both the Summer and the Winter. If your variegated ivy turns solid green, you will need to expose your plant to brighter light and prune the greener parts. Propagating You can propagate a new English ivy from a cutting about 4 inches long. Start the cutting in Spring. Start rooting the shoot in water and then moist soil. The Final Word DO NOT EAT the English ivy, since it has poisonous leaves. They can also cause irritation of the skin. Wear gloves if you experience problems. If you can give your English ivy cool nights and a moist environment, it will love you back. During the Winter do not forget to mist your English ivy or place it in the bathroom right after you shower, closing the door. Your English Ivy is difficult to kill. With just the right small actions of care it will fill your home with...
