Keeping late frosts from freezing tree flowers
The crocuses are running late this year...which apparently means nothing at all. But I sure hope it makes the tree flowers run equally late!
Finding ways to harvest
tree fruits despite late spring freezes is one of my thought projects
for the year. Possible solutions I've come up with include:
- Easily coverable espaliers so I can protect opening flowers from hard freezes.
- Espaliers along an earthen bank so the thermal mass of soil can do the job for me.
- Planting late-blooming varieties.
- Planting standard-sized apples in hopes the blooms near the top of
each tree won't get nipped. (We don't have tree-free room to try
- Finding less frost-prone pockets on our property, perhaps the
south-facing hillside across the way. Unfortunately, this would require
considerable tree removal.
One option I've read about that doesn't seem to work here is:
- Planting trees on the north side of a building or hillside to slow
down their bloom cycle. That's where our high-density apple planting
is...and they still persist in getting nipped each spring.
I'd be curious to hear
from others who regularly see tree flowers in March when you still have
ten weeks of cold weather to go. Have you found any solution to the
frost-nipped blossoms and fruitless years that result?
