leaves stripped off lacecap hydrangea

Question

I have sprayed my lacecap hydrangeas with well known pesticide but most of the leaves and stems have been decimated. What is causing this and how do I stop it? Regards terry griffiths

Answer 1

I suspect the culprit is slugs, since they do come out at night and disappear during the day. While you would not always see them, if you know for certain they are there or find evidence of their nightly visits, this should confirm the fact that they are munching on your shrub.

If it's not slugs, it could be due to other insects or a fungus of some sort. In this case, neem oil may help. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
