Planting and Growing Astilbe
Before you can grow the astilbe you need to decide on the
area in your yard that will accommodate the plant. It is best to choose a section that provides
ample room otherwise you will be transplanting often to prevent overcrowding. When fully grown the plant will be 6 to 40 inches in height and 18 to 30 inches wide.
Decide on the design of your astilbe garden; will you be
growing this plant in masses or with other shade-loving plants; fern, lily of the valley, ladies mantle, or hostas?
What colors will work well with your garden? The flowers come in a variety of colors; white, magenta pink, lavender, and red.

Clear the growing site by removing
the grass, weeds, and debris. For massive
plantings, it is best to use your tiller to break up the soil. Break up the clumps of the soil so that the
soil is a fine texture. Dig a hole in
the soil that is the same depth as the nursery container.
Gently remove the plant from the container by
setting the container on its side and rolling it back and forth, tap gently on
the side of the container to loosen the soil and allow you to remove the plant easily.
Loosen the roots if they are growing
in a ball. Shake the soil away from the roots (gently) before
planting. Set the plant in the center of the
hole with roots facing outward. Backfill the hole with soil mixed with
compost or manure. Water well. Apply pine needles or chipped
wood mulch around the stem of the plant.
If you are planting more than one then allow two feet in between the plants.

Keep the soil moist to moderate but not dry. Set up a drip
line or soaking hose and water deeply every few days during the summer
months. It is better to water the plants with one inch of water every week rather
than water lightly daily. Continue to water into the autumn especially if the season is dry. Keeping the soil moist will prevent plant stress.
After a hard frost prune back your plants and cover them with an organic mulch; pine needles, leaf mulch, or wood chips.

Watch your plants for weak blooms as this is a sign
that the garden is overcrowded. Divide
astilbe and transplant every four to five years.
Every spring apply a spring fertilizer as soon as the plant
starts to grow. If your spring is dry
then water to keep the soil evenly moist, the article will be healthy as long
as the soil does not dry out.
