I’m thinking of building an overhead sprayer/mister. For blossom night frost protection.
I can’t spray the whole garden/orchard for practical reasons. So I’m thinking of grouping all the night frost sensitive species together in 1 spot.
This is where i need your help.
Could you rate/list from wanting to protect the blossoms most to least the fruit tree species you grow/know off? And mention your climate zone or local variables
I’m trying to make a list of trees needing the most flower frost protection.
(from most to least protection needed)
So far i got the following. But I’m not sure of the order. And where to place things like pawpaw and jujube?
I’m in zone 7/8 Europe, Netherlands
medlar (mispilus germanica)
what would you change or add?
Thanks for your help.
Some more information on flower frost sensitivity.
At or near the bloom stage, the critical temperature is the same for almost all fruits and flowers. Freezing temperatures of 28 degrees Fahrenheit will result in about a 10 percent loss and 24 F in a 90 percent loss
The percent of flowers killed in a frost may or may not relate directly to lost yield later in the season. With large-fruited fruits such as apples, peaches, plums and pears, the loss of 50 percent of the flower is not devastating since we may only want a small percentage of the flowers to become fruit. For small-fruited fruits such as cherries, blueberries and grapes, many small fruit are needed for good yields and a full crop. Crop losses due to freezing temperatures are almost always significant in cherries.
These statements make me think it’s most important to protect those that flower earlier. And those that have smaller fruit.
