Should I cut back Amsonia?

Plants must be cut back in either the late fall or late winter to about 8 inches from the ground. Remember to wear gloves when working with Amsonia since stems release a white sap. Though not required, cutting them back again half way to the ground after flowering will result in even fuller growth.

Will Amsonia rebloom?

You will get more flowers if you plant your blue star in full sun, but the plants can handle partial shade and may even grow better there in hot, dry climates.

How do you prepare Amsonia for the winter?

If you are growing this plant in winter, you might want to prune in late fall. This type of winter care is more to promote dense growth in spring than to prevent cold damage. If you decide to undertake this task, trim the plants to about 8 inches (20 cm.) from the ground.

How do you propagate Amsonia?

Plant amsonia seeds in seed trays an inch (2.5 cm.) apart, lightly covering each seed with loose potting mix. Chill planted seed trays for several weeks in temperatures of 30-40 F (1-4 C). After stratifying the seeds for at least three weeks, you can slowly acclimate them to warmer temperatures.

What perennials should not be cut back in the fall?

Don't cut back marginally hardy perennials like garden mums (Chrysanthemum spp.), anise hyssop (Agastache foeniculum), red-hot poker (Kniphofia uvaria), and Montauk daisy (Nipponanthemum nipponicum).

What plants should be cut back in the fall?

Here are some popular perennials that fare well with a fall cutback: bearded iris, columbine, salvia, yarrow, peonies, and day lilies.

Does Amsonia bloom all summer?

The genus Amsonia is made up of about 20 species of clump-forming perennials that bear long-lasting, powder-blue flowers that resemble small stars. They bloom from spring to early summer. The leaves of some species turn vibrant yellow-gold in the fall, adding another season of interest.

Can you divide Amsonia?

To divide an amsonia root ball, simply cut sections of the root ball containing the plant's crown and stems with a clean, sharp knife or saw. Dividing plants like this may seem brutal but the cuts to the root ball actually stimulate plant growth both above and below the soil level.

How do you care for Amsonia?

Amsonia Plant Care

In soils that are constantly moist, Amsonia prefers full sun. Otherwise, plant it in light to partial shade. Too much shade causes the plants to sprawl or flop open. Ideal Amsonia growing conditions call for a humus-rich soil and a thick layer of organic mulch.

Should I cut back all my perennials for winter?

No. Although it's recommended to leave them in place until spring, perennials will usually survive if cut back. But we occasionally have a "test" winter, and intact tops can mean the difference between survival and failure on some types. Some perennials, like mums, always winter best with tops left in place.

Should hydrangeas be cut back in the fall?

These hydrangeas develop buds on growth that forms after flowers bloom and that they hold onto until the following spring. Cutting these back in the fall eliminates new flower buds, leaving nothing but foliage.

Should lavender be cut back in the fall?

Pruning lavender in late summer to fall helps open the plant's interior to allow good air circulation and also removes some of the branches, which can ultimately help prevent winter damage. Ideally, pruning lavender in spring and fall is a great idea, if you can squeeze that into your garden chore schedule.
