Disease Management:
Euphorbia alta is a hardy plant that is resistant to common plant diseases. However, it is susceptible to fungal infections if grown in poorly drained soil or a humid environment. Fungal infections cause leaf spots, root rot, and stem cankers, leading to stunted growth and death. To manage fungal infections, maintain good air circulation around the plant and avoid overwatering. Use fungicides to control the spread of the disease, and remove infected plant debris to prevent reinfection.
Pest Management:
Euphorbia alta is relatively resistant to insect pests. However, it can be affected by aphids, mealybugs, and spider mites. These pests suck sap from the plant, leading to yellowing of leaves, stunted growth, and distorted flowers. To manage insect infestations, use insecticides and natural predators such as ladybugs to kill the bugs. You can also use a neem oil solution to deter insects and reduce their population. Alternatively, prune infected branches and leaves and discard them to prevent the spread of the infestation.
