I love Pea Patch, but in my area, you are paying for sunflowers that the deer are going to nip right as they come up. I've found that a mixture of peas, buckwheat and sorghum works better. Or, if you just want to use pea patch, but a few pounds of sorghum per acre in there to give the peas something climb on. Deer don't eat the sorghum still it seed out and then only the seeds. Oh, and if you want it to last, hit it with some milorganite either at planting or 2 weeks after to keep the off it for a few weeks and let it grow.
