Q.
Can you spray neem oil to rid lemon tree of black mould on leaves and what is best for leaves that are yellowing?
Denese McKinley
A.
Hi Denese, suggest checking on the neem oil packet to see what it is registered to treat, and if black mould is on the list, you can apply it. Yellowing leaves suggest that the plant may be hungry. Apply citrus fertiliser now (October) around the drip line of the plant then again in February.

How do I rescue my citrus trees from borer?

Hi Lorriane, it is a good idea to cut back the branches to below the infected area and paint any wounds bigger than the little finger with pruning paste or a water based paint. Treat with a borer treatment spray from your garden centre - make sure the spray you choose states it will control borer as not all insect sprays do. All the best for treating your tree ^Tui Team
