I put in the supports for the netting, but haven't put the netting in yet. It was wet and I didn't want to get my bolt muddy. I'll wait until it drys. I don't need it in yet anyway. The protection is for the onion maggots. Typically the height of the spring flight is about the time the lilacs bloom. Or at 700 GDD base 40F. If you have never heard of the GDD I talk a little about it here and here. But the height of the spring flight is not the same as when the insects first come out. Something I learned the painful way with the squash vine borer. And that can easily be half the GDD for onion maggots. Right now we are at 207 base 40F. I know because I use my weather station and a spreadsheet to do the calculations. So I'll make sure to have that netting up soon.
