have a Ficus Reginald which I have had for nearly a year. It is
about 1/2 m high and has been repotted several months ago. It is
in a warm room and gets a lot of sun. It has been fine until the
last few weeks when I have noticed some of the leaves turning yellow
and one has some pale brown marks on it. These leaves eventually
drop off. The plant is very slow growing but has new leaves on the
ends of quite a few of the branches. I keep it watered but wonder
if it needs more feeding and have been told that Phostrogen is not
balanced enough. I have checked it over thoroughly for any 'creepy
crawlies' and found none.
are evergreen trees and will drop some leaves from time to time.
If the plant looks healthy there is nothing to worry about. If the
whole tree is dropping leaves, then the plant is likely to be under
stress due to overwatering/underwatering or a feeding problem.
Plants repotted into
fresh new potting mix will have enough fertiliser for at least three
months. Additional fortnightly liquid feeding over the summer months
will benefit the plant. Water plants every two to three days, depending
upon the room temperature. Allow the potting mix to dry out on the
surface before watering again.
Phostrogen is a good
soluble fertiliser, as is Lush, Thrive or Nitrosol.
Osmocote can be applied
at three monthly intervals.
