Do you net them or share the harvest with the wildlife? Can they survive the slug/snail/caterpillar damage (that's a more pressing question for the edible landscaping project obviously as would be left to tend to itself)?
I find that daily checking and hand picking the caterpillars helps a lot. I've also make a spray that is very effective against cabbage moths.
3 C fresh mint
2 bulbs fresh garlic
1 or two fresh cayenne peppers or 2 tsp cayenne powder
3 qts water
biosafe dishwashing soap
Chop garlic (no need to peel), mint, and cayenne peppers (wear gloves for fresh cayenne!) Place these in the water in a pot and bring to a simmer. Cool and strain into a spray bottle. Add a squirt of soap. Spray it on your cabbages, kale, collards, etc., undersides of leaves too. It has to be re-applied after rain or watering. I've brought badly eaten plants back to thriving with this spray.

Alan Carter wrote:It looks like a Daubenton's kale, which grows to make a mound the best part of a metre high and across. Its shoots will arch over and root at the tip, at which it becomes a bit of a sprawling mess. I wouldn't let it do that, but deliberately pot up a new cutting every few years as individual plants only live 5-6 year in my garden. They'll take a moderate amount of shade - 2 hours of full sun should be enough. I find them more pest-resistant than other kales, but you do seem to have a problem there! I'd pick off the caterpillars until it gets established, when it should be more resistant. It might be that they do better in a pest-predator-rich forest garden than in a pot. I've never netted mine and they do sometimes get hammered by pigeons in hard winters, but they always recover and I feel that their need is greater than mine at that point.
