May Gardening Notes

As we begin spring management of our horticultural landscapes, here are a few reminders for the month of May.

• Graft fruit trees from mid -April to early May.

• Abort crab apple fruit with ethephon or naphthaleneacetic acid.

• Prune lylacs right after bloom.

• Stems cut off clean are a sign of rabbit damage. Stems cut off ragged are a sign of deer damage.

• Electric fence smeared with peanut butter and molasses can deter deer.

• Keep raspberry walkway clear of suckers.

• Destroy tent caterpillars.

• Plant peas and lettuce when soil temperature (at a two inch depth) is above 40 degrees.

• Plant spinach and carrots when soil temperature (at a two inch depth) is above 45 degrees.

• Plant beets, parsley, swiss chard and parsnips when soil temperature at a two inch depth is above 50 degrees.

• Harden off seedlings for setting to the garden. Allow one to two weeks for the hardening process.

• Start cucurbit seedlings indoors in peat pots. The cucurbit family includes melons, squash, pumpkins and cucumbers.

• Seed new lawns in early May. Fall is the best time to seed lawns because the grass gets ahead of the weeds.

• Side dress Peonies with a couple handfuls of equally balanced fertilizer like a 15-15-15.

• Deadhead tulips, narcissus, and other spring-flowering bulbs.
