Chilean Lantern Tree - crinodendron hookerianum
I am a very amateur gardener, just trying to get grip with the basics. I bought my plant when it was about 45cm tall and planted it in a deep 40cm pot in ericaceous compost. I wasn't sure if I watered it too much or not enough. After just over a year, when it was flowering the flowers dropped off and the leaves turned yellow and also started to drop off. I fed it worm juice. No better. After alot of research (it's impossible to find anything on caring for this plant!) I decided to feed it with an ericaceous feed with magnesium. It eventually died.
Before I buy another - help - what did I do wrong please?
