I have a grafted has avocado tree that I kept inside for most of last winter (South Africa). It has been outside since November last year and seems to be stalling from the initial good growth when it was inside and also when it first moved outside in summer (November to February).
I have been giving it water twice a week, ensuring it is wet throughout the soil. The soil has got good drainage and the pot has been filled with drainage stones in the bottom, in addition to the holes.
The leaves have started showing brown marks in the middle (not the tips) and some of the top stems also start to look brown. What could this be?
- Could it be getting too much sun?
- Since it was growing well, I don't believe it could be root bound in the 110L pot?
- I added fertiliser during the last week to see if this would help? I guess this will only show in a week or two if the soil was lacking nutrients.
- Could it be that it is too close to the outside LED light that is on during the night?
