Like most houseplants, bright indirect light is best for quality growth. Although a shadier location is acceptable, prepare for slowed growth and exaggerated phototropism. Never allow the Bamboo to endure all-day sun as it'll lead to sun-scorch, resulting in a 'washed-out' appearance. If it were up to us, we'd recommend situating it in a location that offers indirect light in the autumn and winter, while increasing the light to include one or two hours of morning sunlight in the autumn and winter.
Clean conditions are critical for happy Bamboo. If you fail to replace the water on a weekly basis, you'll run the risk of root rot and yellowed foliage. When irrigating, use tepid water to prevent hurting their sensitive roots from the sudden temperature change - if it's too cold for your teeth, it'll be the same with the plant, too! Although rainwater is best, if you decide to use tap water, allow it to stand for 24hrs to settle the levels of both chloride and fluoride. Large quantities of these chemicals will gradually build up in the soil over the oncoming months, damaging both its overall health and the soil quality.
Average room humidity is excellent for Lucky Bamboo, as over-misting may cause the development of powdery mildew or botrytis in areas of poor air circulation. At monthly intervals, perform a gentle hose-down to hydrate its leaves and reduce the number of dust particles resting on its foliage.
Add five drops of a 'Houseplant'-labelled concentrate fertiliser every four weeks, which will translate to once every four water-changes. Don't go overboard with fertilisation as excessive root burn may spell the end of sensitive specimens.
Yellow lower leaves with a blackened or yellowed stem (closest to soil) are a clear sign of poor water sanitation, usually accompanied by too little light - scroll down to the image below for visual reference. Although Lucky Bamboo can do well in darker locations, the frequency of irrigations must be reduced to counteract the chance of root rot. People don't realise that a plant's root system needs access to oxygen too, so when the water stays stagnant for a long period of time, the oxygen will travel upwards and leave the fluid. A lack of accessible oxygen for the roots will cause them to subsequently breakdown over the oncoming days. If the stem's base or roots begins to wither and rot, which is accompanied with yellowing leaves, prune off the main stem so that you're left with the lateral branch on its own. Discard the main stem as the bacteria would have travelled into the new growth to render the specimen useless. As a last resort, place the lateral stem into fresh water to redevelop a healthy root system. Once there is around 3cm (1 1/2 inches) of root growth, place the plant's bottom third in a 7cm pot with a 'Houseplant' labelled potting mix.
Spider Mites are small, near-transparent critters, that'll slowly extract the chlorophyll from of its leaves. Have a check under the leaves, most notably along the midrib, for small webs and gritty yellow bumps.

Yellowing leaf-tips are the product of cold water or too much fluoride in the soil. This issue is caused by using tap water which hasn't sat for 24hrs to alleviate the chemicals via evaporation. We'd recommend switching it for collected rainwater or fresh bottled water to improve its health, along with the reduction of its fluoride-count. The older leaves will always bear the scars of the past, but the new foliage should be as good as new within the next six weeks.
In some cases, a yellow shrivelled stem could be the product of dehydration. If this has happened to yours, sit your plant in more water to see whether it can still competently absorb moisture. Take stem cuttings off its lateral growth if the plant continues to decline; follow the tips provided in the first paragraph of 'Common Issues'.
Lucky Bamboo isn't part of the Bamboo family and instead forms part of the genus, Dracaena. The name derives from the Greek for a female dragon 'Drakaina', referring to the red sap and green foliage. The species' name, 'D. sanderiana', was first penned by Maxwell Masters in 1892, honouring German Orchidologist, Henry Frederick Conrad Sander.
12° - 32°C (54° - 90°F
H1b (Hardiness Zone 12) - Can be grown outdoors during the summer in a sheltered location with temperatures above 12℃ (54℉), but is fine to remain indoors, too. If you decide to bring this plant outdoors, don't allow it to endure any direct sunlight as it may result in sun-scorch and dehydration. Regularly keep an eye out for pests, especially when re-introducing it back indoors.
Over 1.5m in height and 0.6m in width when grown in soil; whilst situated in water, the specimen's growth rates will slow dramatically.
Remove yellow or dying leaves, and plant debris to encourage better-growing conditions. While pruning, always use clean scissors or shears to reduce the chance of bacterial and fungal diseases. Never cut through yellowed tissue as this may cause further damage in the likes of diseases or bacterial infections. Remember to make clean incisions as too-damaged wounds may shock the plant, causing weakened growth and a decline in health.
When the plant becomes leggy, you can also prune the lateral branches in the spring to promote a bushier appearance. We don't recommend pruning its roots due to the risk of damaging the overall health of the specimen.
Via Seed & Stem Cuttings.
Stem Cuttings (Easy)
Small, globular white or pink flowers are arranged along a thick flower shaft that'll appear horizontally towards the top half of the stem, lasting several weeks. It's highly unlikely that a domestically grown specimen will bloom indoors due to the unfavored growing conditions of too low humidity and consistent temperature levels throughout the year.
Converting a water-borne specimen into soil is easy, fun and wholly safe. Not only will the specimen's growth rates quicken in the coming months, but its overall health will also improve dramatically. For those originally in water, place the plant's bottom third in a 7cm pot with adequate drainage to promote good, healthy roots.
For already-rooted specimens, transplant every three years in the spring using a houseplant-labelled compost and the next sized pot with adequate drainage. Hydrate the plant 24hrs before the tinkering with the roots to prevent the risk of 'Transplant Shock'. Add a thin layer of small grit in the pot's base and the lower portion of the new compost to improve drainage & downplay over-watering.

Keep an eye out for mealybugs, spider mites, scale, thrips & whitefly that'll locate themselves in the cubbyholes and undersides of the leaves. Common diseases are root rot, leaf-spot disease, botrytis, powdery mildew & southern blight - click here to learn more about these issues.
This plant is classified as poisonous. If parts of the plants are eaten, vomiting, nausea and a loss of appetite could occur. Consumption of large quantities must be dealt with quickly - acquire medical assistance for further information.
