The Q&A Archives: Allamanda

Question: I have been feeding my Fallam Allamanda with Peters 5-50-17 fertilizer with no results. It that the right fertilizer for the allamanda?

Answer: Allamanda cathartica, also known as Golden Trumpet, is a difficult plant to grow in average household conditions, so any fertilizer you use may not produce the desired results unless your plant is getting exactly the right environment and care. Allamanda needs to be kept warm (minimum 60F degrees in the winter). It's essential that the plant have some direct sunshine each day. Keep the plant well-watered and provide lots of humidity, either by misting the plant or surrounding the pot with water by placing on a tray of pebbles in which you keep a half-inch of water. Once your Allamanda gets the right care, she'll produce those beautiful yellow trumpet-shaped flowers. Good luck!
