| It ain’t pretty but it works. |
As one would expect, cabbage leaf worms love cabbage and nearly every other member of the brassica species. Which is why I’ve become a real fan of row cover material as an insect barrier.

| The perp in question. |
It rarely freezes here so I use the thinnest row cover possible, specifically a product called Agribon-15. If you live in a cooler climate and want to use row cover for frost protection you would use a thicker product such as Agribon-30. Johnny’s Select Seeds carries Agribon row cover in lengths as short as 50 feet–plenty for an urban or suburban garden. I’ve used both PVC pipe and chain link fence tension wire as support. I secure the row cover down with pieces of rebar and bricks to keep out skunks.

It’s not a plug and play solution, however. If it gets hot I have to remember to pull the row cover off. And the added humidity can cause outbreaks of aphids. But overall, it works great. I’ve found that I just need to use it when tender seedlings are getting established. Once they have a fighting chance against the cabbage worms I can pull it off.
