No Deadheading Required
Deadheading astilbe flowers has no positive effect at all and produces no new blooms or flowers. While many other perennials benefit from clipping faded blooms (deadheading) by actually encouraging new bloom and flower growth., your astilbe flowers will not benefit from this practice.

When should peonies be cut back?

Once the plants start to yellow or brown in the fall they should be cut to the ground. Early fall or after the first frost is the ideal time to cut back the plants. Cutting peonies in the fall helps remove foliar diseases and reduce infection next year. Simply cut all the growth off at the soil level and discard.

When can I move hostas?

Splitting hostas is best done in spring or early fall. Ideally, plan on dividing hostas before spring or fall rains arrive. Hostas suffer most when they lose roots, so dig as much of the rootball as possible. If you just need a few divisions, dig small clumps that have formed beside the larger parent clump.

How deep do hosta roots grow?

Hostas are not deep rooting -- their roots are more likely to spread horizontally, which makes the width of the planting hole slightly more important than the depth. A planting hole that's 12 to 16 inches deep is sufficient. Make the width of the planting hole at least one-and-a-half times the size of the mature clump.

Why is my astilbe dying?

Astilbes begin to wilt, sometimes quickly, when they're exposed to too much sun. The hot summer sun can also heat up and dry out the soil. Another symptom of too much sun is leaf scorching; the edges of the leaves may appear burnt or begin to shrivel.

Should coral bells be cut back in the fall?

With pruning shears, cut back the foliage that dies 3 inches above the ground in late fall or early winter. If your coral bells grow as evergreens in your climate, do not cut the foliage at this time. Wait until spring when new growth starts, and cut back any damaged, dead or unsightly stems.

How do you prepare astilbe for winter?

To winterize astilbes and other herbaceous perennials, a gardener removes all stems and foliage down to the soil level in the autumn and tucks the roots in for the winter under a blanket of mulch. Use the garden shears to cut the astilbe stems and foliage back to approximately 3 to 4 inches above the soil level.

Will my astilbe come back?

Eventually, the flowers will dry on the stalks but should stay in place. When winterizing astilbe plants, you can cut all the foliage off, leaving just a 3-inch (7.5 cm) stem above ground. It makes astilbe winter care a little easier, and all new growth will come back to replace it in the spring.

Why are my astilbe turning brown?

A lack of water can cause the symptoms you described. Astilbes need moist soils and perform best in partial to full shade. Next year keep the soil moist, not soggy and mulch. Apply a layer of shredded leaves, evergreen needles or other organic mulch to the soil surface to keep the roots cool and moist.
