any good way to protect blossoms from late frost?
Every year we get a late frost that nips/frosts the blossoms of the plum, peach & apricots (one of each) so we rarely have any fruit to taste in the fall from them. We tried covering them at night with row covers, blankets even tried setting the alarm for 2-4 am to go out & chec the temp. outdoors & have small kerosene smudge pots ready to light under some of them. Is there any way to slow the budding process for later to by-pass those late frosts? I water well thinking that the cold water might slow down blooming or would that even hasten the blossoming? Any easy to use fabric covering that would insulate the trees a bit at night? And an easier way to get the coverings over the tops of the trees .. we've used broomsticks, etc. to hoist the coverings over the tree tops but what a chore & takes 2-3 people to do it! The Bing cherry & the apple trees are later blossoming .. just starting to show some color so think we may be able to harvest fruit from them. Our average late frost is about mid April I think here in zone 7. Our trees are all of the dwarf variety simply to be able to take care of that height better. Any ideas surely appreciated!!
