How To Plant Astilbes
Astilbes grow best in zones 3 to 9. The Astilbe is a shady perennial, so it needs shade in order to thrive.
The best time to plant this garden treasure is at the beginning of Spring or Fall. It’s best to start with a division of the plant, rather than from seed because they’re difficult to grow and time-consuming to germinate.
This is definitely not a plant that appreciates full sun, so make sure you choose an area in your yard that gets a few hours of shade each day, with about an hour or two of morning sun.
(If you’re worried about finding a shady area, try the eastern part of your home, where shadows from your house will provide your plants with the protection they need in the afternoon.)
This flower can grow anywhere from 6 inches to 5 feet tall. Its fluffy, fern-like flower clusters bloom all Summer long (*depending on the variety, so check with your local nursery) and can be found in glorious shades of pink, purple, yellow, orange, blue, and red.
If you’re planting a bare-root astilbe plant, dig the hole two times as large as the bulb and about 5 inches deep into the ground.
Make sure that the crown is facing upwards and planted only about 2 inches from the topsoil, with the roots facing downward and deeper into the ground.
After you plant your astilbes, make sure to deep-water the soil so that the roots soak up what they need in order to settle into their new home.
Companion Plants for Astilbes
If you’re planning the layout of your garden and are wondering what plants you should place near your astilbes, then the hosta, ligularia, heuchera, trilliums, and Siberian Iris are options you should consider.
Astilbes mix exceptionally well with other moist-soil and shade-loving perennials, so take a pick according to your preference.
Plus, shade-tolerant plants like the hosta can serve as garden fillers and provide some extra greenery and contrast to your tall, fern-like astilbes.
If you remember one thing about growing astilbes, let it be this: Astilbes NEED moist, well-drained, organic soil. Compost mulch or bark chips can help keep the soil moist during stifling hot Summers.
This flower can also benefit from a good fertilizer, so try incorporating the fertilizer into your soil a few days before planting.
How to Water Astilbes
As discussed above, astilbes need lots of moisture and protection from the sun.
So, you should aim for weekly deep-waterings, and pay extra attention to the moisture in your soil throughout the week.
Check on your plants daily to make sure the soil is nowhere near dry.

This flower actually doesn’t need any deadheading, making them even easier to take care of than other perennials.
