hi, i've grown a lychee from seed, its kept indoors because i doubt the english climate is suitable for it. it has plenty of root room and i occasionally use baby bio fertilizer on it. its just over half a year old and about nine inches tall, it happily grows new leaves constantly and hasnt lost any yet. however quite often the tips of the leaves turn brown and in other random locations on the leaves in the older ones. i mist it quite often to maintain humidity but i could do this more often. its on a north facing window and other than the tips turning brown it seems very happy. any adivce or help would be most welcome. some people suggest trimming the brown tips off, i assume this is just for asthetics. any suggestions for fertilizer types? many thanks
