I have been thinking about pilling snow round some of my peach trees the next time it snows to help keeping them cooler longer after it snows would this work? I have also read that you can paint the trunks white to help delay blooming but I don't know how well it works and I hate the way it looks. Anyone have any ideas ?? TIA
In Peter Bane's book "The Permaculture Handbook" he does mention piling snow at the base of the tree. Supposedly this works because soil temperature is one of the primary variables influencing when flowers bloom. Snow around here is rarer than hens' teeth so I have no idea if it actually works. Would love to hear if you have any success with it since my SO and I are planning to move to New England next year. He also suggests that you might consider planting tree species prone to this problem on the north side of your house. Ideally just far enough away that most of the canopy is in sun while the base is still in the shade until after the danger of frost has passed. Won't do you much good with your existing trees, though.

I thought the white paint was mainly to reduce sun scald. Piling up snow sounds like a good idea to help keep the soil temperature lower for longer. You might find this article interesting.

Which varieties of apples do you plan on using? I'm finding it difficult to find information on when trees actually bloom. I'm planning on making an order from St Lawrence nursery soon.
I'm in AZ too, at 7300'. Would love to try the snow idea, if we get any more snow, and if the snow actually sticks around.
