have recently acquired a weeping fig. It desperately needed repotting,
which I did about 2 months ago. The soil developed a thick covering
of white mould/fungus and the leaves started to yellow and fall
off. I repotted it again, carefully removing all the "infected"
soil and replacing it with freshly purchased potting mix. The fungus
hasn't returned but the tree is still losing a lot of leaves
it's nearly bald! I've moved it away from any direct light and draught
but I don't seem to be making any progress.
is a white fungus that grows in potting mix and does not affect
plants, although it can look unsightly, and over time will disappear.
The white mould could
also be mealy bug in the potting mix they are much harder
to control. For this, you will need to drench the potting mix with
Malathion or Maldison and let the plant sit in a saucer for at least
half and hour so that the potting mix becomes saturated. It is best
to do this outside as Maldison has an unpleasant smell.
Trim the plant back by
about a third to encourage new bushy growth. As temperatures start
to warm up, you will find that growth will start to move. A repeat
drench may be required.
