Such a feeding should be a rare and infrequent dosing. For in-water plants, the solution for lucky bamboo stalks turning yellow is to immediately change the water.
This can work in some cases where the plant hasn't soaked up too much fertilizer to kill it. However, in other cases, it might be too late to save the plant.
This is especially true if it's the stalk turning yellow instead of just the leaves. The best approach for an over fertilized in-soil plant is to repot with fresh soil that doesn't have any added fertilizer. The damage may have already been done, and the plant absorbed too much fertilizer. You'll know within a few days if your plant will survive. If your lucky bamboo leaves are turning yellow and you've ruled out all the above possible causes, then it could as simple as too cool a temperature.
A low humidity environment is problematic. Remember, the plant's natural environment is that of a very humid rainforest. Since the lucky bamboo prefers a humid climate, you may need to remedy a dry one by misting the leaves every two to three days.
This will give the plant and leaves the high moisture it craves. This should stop the plant from turning yellow if low humidity is the cause. If you've tried all the recommendations and your plant is still on a decline with yellow leaves and stalk, it may be time for drastic last-ditch efforts. You can salvage your plant. Never throw it away without first trying one of the two propagation methods for salvaging what is typically an expensive plant.
If your plant has a few yellow leaves, then you can snip them with a pair of scissors. This is especially necessary if your plant is suffering from too much water or direct light. Better to remove them so new leaves can grow. However, if your lucky bamboo stalk is dying, then you have only one recourse, and that's to cut the green sprouts and root.
If the roots are still good but the upper part of the stalk is yellow, you can possibly salvage it. The first thing to check when a plant begins to turn yellow is the root system. You can quickly assess its health by examining the roots. The color of healthy roots are reddish or orange. Diseased roots are brown, black, or gray and need to be removed by cutting off where they protrude from the stalk. Cut off the yellow part along the line where green is still showing.
If the stalk continues to turn yellow and no new sprouts develop, the plant can't be salvaged. The draftiness from the air conditioner or heater alters the temperature too much. This could cause leaf or stem yellowing and other maladies for your dracaena. Otherwise, you want to pay attention. First, you have to give your lucky bamboo the right amount of water.
Most gardeners keep water levels no more than two inches over the roots, others only one inch. You want to replace that water about every week and definitely no longer than every 10 days. The bowl itself needs your attention as well. If you notice green gunk in or around your bowl, then your lucky bamboo has a case of algae. These bacteria can spread to the roots. Get into a regular bowl cleaning schedule.
Okay, so what if you go the old-fashioned route and plant your lucky bamboo in soil like you do your other houseplants? Press your finger gently on the surface of the soil.
How does it feel? Now, you may wonder, since lucky bamboo can sit in several inches of water, will a bit of overwatering hurt it?
Yes, it can. As you recall, mold and algae can grow on the plant , and these can cause root rot. The mealybugs themselves are pinkish-gray in color and typically have a white wax on their bodies. To get rid of an active infestation, try spraying them off with water, pruning shoots that are infested, or even using chemical means, like horticultural oil or insecticidal soap.
Stay away from broad-spectrum pesticides that could also harm beneficial insects. Most indoor houseplants can exist on ordinary tap water. However, a lucky bamboo plant is a bit more sensitive than the average indoor houseplant.
Exposing your lucky bamboo to chlorinated tap water can be damaging. The leaves wilt and turn yellow, and eventually, the plant will die. To give your bamboo clean water from the tap, try leaving a cup or bowl out all night so the chlorine will dissipate, and then water it in the morning.
Another option is to invest in a water filter, which is much faster and more convenient than leaving a bowl of water out all night long. A very popular option is to pot lucky bamboo in water with a substrate, like small pebbles or decorative rocks. If the stem is dying, you can try trimming off that portion of the stem.
Your other option is to remove the sprouts from the stem and place them in water. The sprouts may develop roots and begin to grow a new stem. Darcy Logan has been a full-time writer since Before writing, she worked for several years as an English and special education teacher.
