Difference between revisions of "Care for an Indoor Bamboo Plant"

There are hundreds of bamboo species you can grow indoors, from colorful table plants to majestic centerpieces. Bamboo tends to be more stressed in an indoor environment, so plenty of tender loving care is required. A close eye on moisture is especially important to make sure the bamboo is getting plenty of water without soaking in soggy soil.<div style="background-color:#D2E9B8; color:#000; margin:0px; width:90%; padding:2px; float:right; border:3px; border-style:solid; border-color:#93B874; {{border-radius|15px}}">Follow the [[Take-Care-of-Lucky-Bamboo|lucky bamboo instructions]] if your plant:<ref name="rf1">http://www.bamboo.org/FAQ.html#HowCanIFindOutWhatKind</ref><br>– has a species name beginning with ''Dracaena''<br>– is labeled Lucky, Chinese, Water, or Curly Bamboo<br>– has red or orange roots as an adult<ref name="rf2">http://www.guide-to-houseplants.com/lucky-bamboo.html</ref><br>– ''or'' has been growing in water, not soil</div>

#Find a wide, squat pot. Choose a container with twice the diameter of the root ball, or with at least 2 inches (5 cm) of space between the root ball and the sides. Good drainage is key to the survival of most bamboo species, so make sure there are sizeable holes in the base of the pot.<ref name="rf3">http://www.bamboogiant.com/aboutBamboo/planting.php</ref>

#*Line the container with plastic root barrier if it is cement (which can damage bamboo) or wood (which lasts longer if protected from moisture).<ref name="rf4">http://bamboosourcery.com/cat_frame.cfm</ref>

#Consider a humidity tray. Bamboo loves humidity, which can make indoor growing a challenge. Keeping water under the bamboo without letting it soak the roots is the easiest way to add moisture to the air. There are two ways to set this up:<ref name="rf5">http://www.bamboogarden.com/Interior%20Bamboo.htm</ref><br><div style="background-color:#D2E9B8; color:#000; margin:0px; width:45%; padding:2px; float:left; border:3px; border-style:solid; border-color:#93B874; {{border-radius|15px}}"><b>Pebble tray</b><br>1. Fill a tray with a layer of pebbles.<br>2. Add a shallow layer of water to the tray.<br>3. Place the pot on top of the pebbles, without touching the water.</div><div style="background-color:#D2E9B8; color:#000; margin:0px; width:45%; padding:2px; float:right; border:3px; border-style:solid; border-color:#93B874; {{border-radius|15px}}"><b>Gravel</b><br>1. Put a layer of gravel in the bottom of the pot.<br>2. Place the pot in a shallow tray of water.</div>

#Fill with well-draining soil. Bamboo needs a soil with light to moderate density: fast-draining, but able to hold moisture. You can use a standard potting mix, or make your own from ⅓ loam, ⅓ perlite (or washed sand), and ⅓ peat moss (or well-rotted compost).<ref name="rf4" /> Most bamboo can tolerate a wide range of well-draining soils, so the exact composition won't make or break your plants.<ref name="rf6">http://www.bamboobotanicals.ca/html/bamboo-care/soil-for-bamboo.html</ref>

#*Bamboo tends to do best in slightly acidic soil, with a pH between 5.5 and 6.5, but most species tolerate a pH up to 7.5.<ref name="rf3" /><ref name="rf7">http://halfsidebamboo.info/http:/halfsidebamboo.info/wordpress/590/a-soil-primer/</ref> Most soil falls into this range.

#Plant your bamboo at a shallow depth. Keep the stem and the top of the root ball above the level of the soil to prevent rot.<ref name="rf8">http://www.bamboofarmingusa.com/How-to-Plant.html</ref> Press the soil down to get rid of air bubbles, and water in the plant with a good soak.<ref name="rf4" />

#*If your bamboo came rootbound, cut it out at the edge of the pot with a clean knife. It's probably had trouble getting water, so soak the root ball (but not the stem) for 20 minutes before planting.<ref name="rf9">http://gardeningstepbystep.com/how-to-grow-bamboo/</ref>

#Water your bamboo carefully. This is the most difficult part of growing bamboo indoors, since bamboo is both thirsty and vulnerable to overwatering.<ref name="rf10">http://www.bambooworld.com/FAQRetrieve.aspx?ID=46983</ref> To start out, water until a little water runs out the base. Let the top 2 or 3 inches (5–7.5 cm) of soil dry out before each watering session. If the soil stays moist for more than a day or two, reduce the amount of water.<ref name="rf4" />

#*If the top of the soil is drying out quickly, dig down to 4 inches (10 cm) deep to check for moisture. This depth should stay lightly moist most of the time, especially during the first three months after planting.<ref name="rf11">http://bamboosourcery.com/cat_frame.cfm?sec=44&row=10</ref>

#Keep it humid. Most bamboo plants prefer humid air, especially in hot weather.<ref name="rf12">http://www.bamboo.org/GeneralInfoPages/GrowingBambooIndoors.html</ref> As long as you avoid overwatering, any one of the following should keep your plant happy:

#*Lightly mist the leaves with a spray bottle every couple days.<ref name="rf5" />

#Find the right light level for your species. If you know the species name of your bamboo, look it up to find specific recommendations. If your plant needs more light than your climate provides, [[Grow-Plants-With-Grow-Lights|install evening grow lights]]. If you don't know the species, start with these rules of thumb:<ref name="rf12" /><br><div style="background-color:#D2E9B8; color:#000; margin:0px; width:45%; padding:2px; float:left; border:3px; border-style:solid; border-color:#93B874; {{border-radius|15px}}"><b>Needs more light:</b><br>–plants with small leaves<br>–tropical species<br>–plants kept in warm rooms</div><div style="background-color:#D2E9B8; color:#000; margin:0px; width:45%; padding:2px; float:right; border:3px; border-style:solid; border-color:#93B874; {{border-radius|15px}}"><b>Needs less light:</b><br>–plants with large leaves<br>–temperate species during dormant winter periods<br>–plants kept in cool rooms</div>

#Fertilize your bamboo plant. Bamboo grows quickly as long as it has room in the container, and needs extra nutrients to support this growth.<ref name="rf5" /> A dose of slow-release fertilizer at the beginning of the growing season is a good way to provide a steady supply.<ref name="rf4" /> You can use a balanced fertilizer such as 16-16-16, or a high nitrogen (N) fertilizer such as 30-10-10. The high nitrogen option discourages flowering, which weakens many bamboo species.<ref name="rf12" /><br><div style="background-color:#ff9999; color:#000; margin:0px; width:90%; padding:2px; float:right; border:3px; border-style:solid; border-color:#000; {{border-radius|15px}}"><b>Warning:</b><br>–Do not fertilize within 6 months of buying. Most plants get enough fertilizer from the nursery.<ref name="rf4" /><br>–Avoid seaweed-based fertilizers due to excessive salt content.<ref name="rf9" /></div>

#Prune regularly. Most bamboo is very tolerant of pruning, so don't hesitate to shape it once it is established and healthy:<ref name="rf12" />

#Re-pot or divide when the bamboo outgrows its container. Bamboo can grow in two different patterns depending on species. "Runners" send out long shoots to start new plants, and will spiral around a large container within three to five years. "Clumpers" grow steadily outward, and may last up to six years in the same pot. Any bamboo plant needs a transplant to a larger pot once it becomes rootbound.<ref name="rf13">http://www.bamboogarden.com/FAQ%20general.htm#plant%20pot%20in%20the%20ground</ref>

#*To restrict growth, instead dig up the plant, cut away about ⅓ of the roots, and replant in the same container with fresh potting mix.<ref name="rf12" />

#*You can [[Propagate-Bamboo|propagate]] most bamboo plants by cutting the stalks and replanting in separate containers. This does not work on bamboo with no hole in the center of the stalks, or only a very small hole.<ref name="rf14">http://www.permaculturenews.org/resources_files/farmers_handbook/volume_4/9_bamboo.pdf</ref>

#Find the cause of leaf drop. It is fairly common for a bamboo plant to lose a lot of leaves when moved indoors or transplanted. As long as the new leaves at the ends of branches look healthy, the plant should recover. If those leaves drop or look unhealthy, a couple months outdoors (if climate allows) can help recovery.<ref name="rf10" /> If your plant has been in the same place for a while, look into other possible causes:

#*Temperate species often drop leaves during low-light conditions. A cool, low-light dormant period in winter is good for these plants, and reduces leaf drop. The fewer green leaves there are, the less water the plant needs.<ref name="rf12" />

#*Many species drop leaves in spring (or less commonly, fall), gradually replacing them with new ones. If there's a mix of green leaves, yellow leaves, and new, unfurling leaves, the plant is probably fine.<ref name="rf15">http://www.bamboogarden.com/care.htm</ref>

#Fix curling or drooping leaves. If the sides of the leaves roll inward, the plant needs watering. (Photosynthesis consumes water, so the plant is reducing it by avoiding sunlight.) If the leaves droop downward, the plant is overwatered, or the soil is not draining fast enough.<ref name="rf11" />

#*If they look dry and the tips are brown or curling upward, the plant needs more water. It may be rootbound and in need of a larger pot.<ref name="rf4" />

#*Leaves that slowly become paler and more yellow usually have a nutrient deficiency. Add fertilizer with added minerals.<ref name="rf10" />

#Respond to insects and disease. Indoor bamboo plants are more vulnerable to these problems, especially if there is low air flow in the room. If there is a light insect infestation, wash the leaves with insecticidal soap, or spray it outdoors with an insecticide spray.<ref name="rf4" /> If this doesn't work, or if you think the plant has a disease, try to identify it and respond:

#*A black "sooty" mold is usually caused by insects. [[Control-Aphids|Remove aphids]] and [[Remove-Ants-from-Potted-Plants|ants]].<ref name="rf16">http://www.tropicalbamboo.com/bamboo_maintenance.asp</ref>

#*Circular fungus rings or grey/brown scale usually do not harm the plant. An anti-fungus treatment from a garden store can remove it.<ref name="rf16" />

#*Wet, rotting patches are a sign of overwatering, but may be helped along by infestations. Dry them out and treat with insecticide or fungicide.<ref name="rf17">http://www.frienvis.nic.in/WriteReadData/UserFiles/file/Content-Page/Books/Bamboo/Diseases-of-Bamboos.pdf</ref>

*Find specific information on your species whenever possible. Species that do well indoors include ''Indocalamus tessellatus'', ''Phyllostachus nigra'', and ''Bambusa multiplex''.<ref name="rf12" /><ref name="rf10" />
