Southern Tier here. Temps have been tough on our flowering trees and bushes. Our mock pears only had about 1/4 the usual blossoms, then went to leaf after only two weeks. Guessing we will have skimpy foliage on those this year. Lilacs look as though they won’t be much better. Forsythia - leaves and virtually no blossoms. Last year they were great.
I think I know what is in store for my peach tree. My apple trees have not done a diddly darn thing since planted years ago - but at least I won’t have any sense of disappointment with those.
My teeny row of snow peas is doing OK, but we can NOT plant anything else until the end of May. Grampys wisdom. One year we got cocky, and we paid for it, LOL. We can plant seeds to ground mid May, but no started plants. EVER.
The average last frost date here in Western NY is 5/20 , so frost blanket, cloche, and cold frames are useful, and frequently needed in the garden.
I would suggest a side dressing of compost and/or 5-10-10 within the dripzone to feed any delayed foliage formation and fruiting blooms .
If not used by the plant this year , it will build up the plant nutritionals for next years production so it won't be totally wasted.
Last week, apple orchards around here expect 30% reduction in blooms due to frost, but the resulting fruit may actually be larger, depending on the rest of the season.
If the blooms aren't blasted and desiccated , there is still a chance of delayed blooms.
