2018 Garden Week 3

I got seversl scion woods from exchange last Sat. So, I bought two bareroot trees from Costco to graft. The 1st tree is flavortop Nectarine that I grafted speckled Egg Nectarine and Kit Donnell peach. The 2nd tree is Elberta Peach that I will graft suncrest peach and fairtime late peach. When will I harvest? 🙂
