Q. In Zone 6b, at what dates can just one plant perennials and annuals safely?

J.M., Belmont

A. It is now harmless to plant frost-delicate annuals like impatiens, summer months veggies like tomatoes, and tender herbs like basil. Perennials are by definition winter season hardy, so you can plant them nearly at any time the soil isn’t frozen, though the greatest months are April, May well, September, and October partly due to the fact they get the most rain. The very same is correct of trees and other woody crops. By June 8, it is harmless to plant everything, and it is also protected to move houseplants outdoor.

 

Q. Should peonies be cut back again like the other perennials you mentioned a couple of months ago, specially Montauk daisies and phlox? (“Talk to the Gardener: Growing sunflowers to help Ukraine,’’ April 24) Peonies have a lot of buds ideal now, so would reducing some of them off final result in more bouquets?

J.C., Dover, N.H.

A. You can slice back again tall drop bloomers this sort of as New England asters now to make them shorter and bushier, but not spring and early summer bouquets like peonies. If you pinch off peony aspect buds, you will get fewer but bigger flowers. I established up peony hoops for each plant to develop up via in late April. With out staking, the large cabbage head flowers will bend or break if you water them though they are blooming. So don’t do it. If it rains, just harvest the bent ones for bouquets. Kinds with solitary petals normally don’t require staking but are not as aromatic.

 

Q. Two of my rhododendron bushes are beginning to fail. The roots of the bushes turned black, and the leaves started to die. Is there something I can do to rehabilitate them? I have others at the opposite side of the garden mattress that are the same age and thriving.

C.M., Manchester, N.H.

A. Rhododendrons are reduced-servicing shrubs, but they have to have humidity when it is dry. Drinking water the root space deeply at the time a week, and go over it with 3 inches of bark mulch to help retain the humidity. When mulching any trees or shrubs, depart a mulch-no cost “doughnut hole’’ around the woody trunk to stop rotting. Utilize a fertilizer specifically for acid-loving crops each individual spring. Give rhododendrons excess drinking water in October and November so their evergreen leaves can lock in dampness for the wintertime. Think about relocating rhododendrons that are exposed to winter winds that can dry out the evergreen leaves, turning them brown.
