Cabbage

Its been a bad year for my cabbage they have been eaten to bits i had them covered with netting also tried fleece have put slug pellets down is there anything else one could suggest for next year ??

 

"Next year I will get some better netting with no gaps."

I found one in my debris netting a few days ago, first one this season, no idea how it got in, but my best guess (and I've been expecting it all season) is the "gaps" in debris netting to allow it to have scaffolding poles [I assume] threaded through.

If you are going down the debris netting route next year it might be an idea to plan to sow-up the scaffolding holes as a Winter job?
