Diseases
Poinsettia leaves turning black is a common problem that can have several causes. This can be prevented by giving the plant a break from direct sun and moving it to a shadier spot. This can be prevented by fertilizing less often or using a weaker fertilizer. Another common cause is too much sun, which can scorch the leaves. The most common cause is overwatering, which can lead to root rot. If the leaves are turning black from the tips, it could be due to too much fertilizer, which can burn the leaves. This can be prevented by allowing the soil to dry out between watering.
– Alternaria Leaf Spot
Alternaria Leaf Spot is a common problem for poinsettia growers. Alternaria Leaf Spot is most common in humid or wet conditions. The best way to control the disease is to water the plants in the morning so the leaves have time to dry before nightfall. The disease is caused by the Alternaria fungus, which infects the leaves of the plant. The fungus can cause the leaves to turn black and fall off the plant.
– Bacterial Leaf Spots
Bacterial leaf spots are one of the most common problems that poinsettia growers face. The spots are usually black or brown and can be circular or irregular in shape. They are often surrounded by a yellow halo.
Bacterial leaf spots can be caused by a number of different bacteria, but the most common is Pseudomonas cichorii. This bacteria is often spread by water, so it is important to water your poinsettia from the bottom up and to avoid getting the leaves wet.
Once a plant is infected with bacterial leaf spot, there is no cure. If you do see spots on your plants, remove the affected leaves and destroy them. The best way to prevent the disease is to start with healthy, disease-free plants.
– Anthracnose
If you notice your poinsettia leaves turning black, it’s likely due to a fungal disease called anthracnose. The good news is that anthracnose is not deadly to poinsettias and can be treated with fungicide. Anthracnose can affect any part of the plant, but is most commonly seen on the leaves.
They will be able to tell you for sure and also recommend a treatment plan. If you think your poinsettia has anthracnose, the first step is to confirm with a plant doctor or nursery.
Be sure to treat the entire plant, even if you only see black leaves in one area. Treating anthracnose is relatively simple and just requires using a fungicide according to the directions. With treatment, your poinsettia should make a full recovery and be back to its beautiful self in no time!
