I'm doing a sunflower patch 20' long x 7-8' deep. How far apart should I space the sunflowers? They are gonna be different kinds staggered short to tall. Also if I can't get my hands on some straw, could I use some of my left over leaves from fall that I haven't chopped up yet for mulch?

Also does anybody know when it would be safe to remove my berry netting from my seedlings. Last year my sunflower seedlings only got about 6"s tall when they got top off by something. I was gonna stake 2 feet high and throw my berry netting over the stakes to protect my baby sunflowers.

Thanks
