Growing Cauliflower

I have grown cauli from seeds. In a greenhouse. Have noticed holes in the leaves thinking it was snails I put crushed egg shells in the pots along with snail bait, only to find last night small green caterpillars, happily munching away on a new leaf. I sprayed the entire plant with soapy water in a squeeze bottle. Was that the right thing to use. Even though I used bait I would rather have used something natural. Help needed

The most effective organic solution to your problem is B.t. (B. thuringiensis). It's a naturally occurring bacteria that only targets the caterpillars but is harmless to everything else. Soapy water can be useful for aphids but probably won't do much to the cabbage loopers unless you use so much soap that you risk harming your plants.

Neem oil will get rid of the caterpillars, if you don't feel confident to pick them all off. Follow instructions on bottle.

Look up on the internet organic sprays for cabbage/caulies.
