| Between personal observation and hearing stuff on local radio:
In Northern Ohio, there will be no blooms/fruits this year from:
Flowering Pear ("Bradford" or "Callery" pear as some call them)
Flowering Crabapple
Flowering Cherry
Redbud
Forsythia (they were already blooming, now limp)
Lilacs
Hydrangea
Apricots
In most (95%) cases the plants will survive, but only get new leaves and not flowers.
Marginal (some may bloom/fruit, some not):
Fruiting Peaches
Fruiting Cherries
Dogwood
Probably OK:
Tulips
Late-blooming Daffodils
Most late bulb flowers
Anything that blooms after June 1 (roses, Butterfly Bush, etc)
Apples
Pears (fruiting pears)
Plums
Strawberries
Raspberries
Blackberries |
