Astilbe Planting and Care Guide

Quick Facts About Astilbe

Astilbe plants are strong, robust shade-lovers that produce large, colorful plumes of color in the early summer. They come in various heights and colors, but all Astilbe plants are long blooming and low maintenance. They have a lacy foliage, making them a great addition to the shady border even when they're done blooming.

Planting Time

Start Astilbe seeds about 8 weeks prior to the end of frost season. Transplant outside once frost danger has passed.

Planting Location

Astilbe plants do well in partial shade. They can tolerate full shade as well. The plants need fairly moist, fertile soil. Astilbe plants can be in the border or in containers.

How to Plant Astilbe

  • Fill starter trays with moistened seed starting soil
  • Astilbe seeds need light to germinate, so press the seeds into the soil but do not cover them
  • Lay clear plastic wrap loosely on top of the tray to help hold in moisture
  • Place the tray in a bright, warm window
  • Lift the plastic wrap each day to mist down the soil and seeds
  • Once sprouts emerge, remove the plastic wrap
  • Continue growing the Astilbe in a bright sunny window or under grow lights
  • Water the plants daily
  • Once there are true leaves, provide a water soluable fertilizer diluted to half strength
  • Harden off the plants for 7 - 10 days prior to transplanting outdoors

Care And Maintenance

  • Astilbe prefers regular irrigations - especially to get the plants established
  • Each spring, provide a balanced fertilizer for the plants - like a 10-10-10
  • The plants can be divided every 3 - 4 years 
  • No deadheading is needed - once the plumes are done, they can fade and dry - remove when desired
