I have a Litchi plant grown from a seed that doesn't seem too happy. It keeps growing new leaves, but each time a fresh set appears, the old ones turn brown.
It seems unable to carry more than two pairs of leaves simultaneously. It's placed in a south facing window in southern Sweden, which this time of year means quite a lot of sun and warmth.
I've tried giving it rain water (which I've read it would prefer) and watering it only when the soil is no longer wet, but nothing seems to boost it's growth. Any ideas?
