Hi, I'm wondering if anyone is familiar with this product called Cloud Cover, and it's application for Japanese Maples. One of the nurseries I visited recently advised me that it was a very good product for preventing leaf scorch in the hot summers here (zone 9). If anyone uses this product, I'd like to hear your success (or failure) stories. For those who do use it, when is a good time to apply? I would guess the best time would be as late in the season as possible...after most/all of the leaves have fully emerged and formed. Thanks!
