I just transplanted my kale starts and I'm going to put my cabbage & broccoli plants in next. Last year we had some significant damage & developmental delays from cabbage moth caterpillars and I want to avoid that this year.
From what I've been reading, row cover looks like a good option for me. However, I haven't come across information about when the plants need to be covered or for how long. Where can I find this information.
(FYI, I'm in northern VT, zone 3-4. For reference, the lilacs are just now beginning to bloom.)
