I have been growing this avocado plant from pip - it is now nearly 4 years old and about 5ft high. I water it regularly but never so it sits in water and prune the ends to stop it growing larger.
Does anyone know why the lower leaves are tinged with brown (and sometimes go totally brown/yellow and fall off!).
Also, how do I encourage more leaf growth lower down on the plant? Any help greatly appreciated. Thanks in advance. J x
