Our area gets hit with hail pretty often, but weirdly enough, my yard usually gets bypassed. At least this year I'm not on any kind of garden tour. I've talked to a few gardeners and nursery owners this morning, and have cause for hope.
Word is, the vegetables should bounce back stronger than ever. Roses also. Hostas---not sure.
Bayer 2 in 1 rose food was on sale at Lowes so I bought enough to feed the worst hit areas. A few people said we just have to cross our fingers that plants can grow new leaves and get them hardened off before the extreme heat sets in. Hail compacts the soil, which leads to bigger problems with watering later on in the heat. Most of the flower beds had mulch or groundcovers to lessen the impact.
Young trees and shrubs with damaged stems are at high risk for insect and disease, so I may spray them if the wind ever stops.
