Hi Everyone,
I have some cabbage and kale planted last September which are doing well, but are still being eaten. I don’t suppose the slugs will ever stop, but I have found some green caterpillars again. They were there before winter as well. They probably came in on garden centre purchased plants (never again, grow form seed from now on). I recognise them as cabbage white butterfly caterpillars. Does anyone know if it’s too early to start using Bacillus Thuringiensis (BT)? And also how often should it be used. I usually use about a teaspoon in a litre of water.
