I’m talking specifically about Early Blush, which bears fruit about 2 weeks before my next earliest cot. Alfred was planted against my wall 20 years ago and is my strongest most reliable tree- you should try planting or grafting Alfred. It has as good a fruit as any, just a bit small and a tendency towards scab, which can be controlled. Cummins told me long ago that it was the most reliable of all trees being looked at in Cornell’s breeding program.
Last year I got my cots without insecticide and I haven’t sprayed them with it yet this year. I’m waiting to see if they start getting damage- PC usually only attacks more immature fruit than what cots are by the time PC comes out in my neighborhood. Cherries only need a single spray, it seems.
