Questions

I have pots filled with marigolds and violas. Some insect is eating the buds of the violas, can you suggest a spray to prevent this happening. I keep slug pellets around the edge of the pot.

I planted a standard flowering cherry tree in late April approx. 3m tall and staked it well. In the last few weeks I have noticed tiny holes in the top leaves and now brown patches on the leaves. What can i do?

I have a few mature plants of st. john's worth, however they appear to be badly damaged after the winter. There are a few shoots on 2 of them, the rest are just brown. Should i cut them back .
