Aster Planting and Care Guide

Quick Facts About Aster

The Aster plant is as versatile as it is beautiful! Depending on its height, the plants are perfect for borders, rock gardens, or wildflower gardens. Use them as cutflowers too. Asters are valuable pollinator plants for bees and butterflies, and the tasty seed heads are sought by birds.

Planting Time

Aster flower seeds can be started indoors 6 - 8 weeks prior to the end of frost season or directly seeded outdoors in the spring. Perennial Aster seed does best with a 30 day cold treatment prior to starting the seeds, but annual Aster seed does not require the cold treatment.

Planting Location

Asters grow and flower best in full sun. Some varieties will tolerate part shade but will have fewer flowers. Soil should be moist but well-drained, and loamy. Wet clay soil will lead to root rot and dry sandy soil will lead to plant wilt. Mix 2 to 3 inches of compost into the soil prior to planting.

How to Plant Aster

  • For indoor planting of perennial Asters, prepare seeds by mixing them into some damp sand and keeping the mix in the refrigerator for 30 days prior to planting in starter trays
  • For annual Aster seeds, no cold treatment is needed
  • Press the Aster seeds into the soil and only lightly cover
  • Keep moist and warm for germination
  • Harden off the seedlings and transplant out into the garden once frost danger has passed
  • Or, in areas with long growing seasons, prepared the garden soil
  • Add compost to improve drainage and add nutrients
  • Scatter the flower seeds on the surface and lightly cover
  • Keep moist for germination
  • Thin the plants to the proper spacing depending on the type of Aster
  • Pinch back young plants 1 - 2 times to encourage bushier growth

Care And Maintenance

  • Watch the Aster plants for any sign of stress
  • During dry periods, water the plants regularly
  • Mulch around the base of the plant to keep weeds down and help hold in moisture
  • Stake taller plants and protect from winds
  • In winter, cut the plants back

How Much Seed Do I Need?

1. Measure

For Squares or Rectangles: measure the length and width of the space where you want to plant. 

For Circles: find the radius - measure the widest part of your planting space and divide by 2.

2. Calculate Square Footage

Square Foot Calculations

For Squares or Rectangles:  length (in feet)  x  width (in feet) = square feet

For example, a garden that measures 50 feet x 30 feet = 1500 sq. ft.

For Circles:   radius (in feet) x  radius  x 3.14 = square feet

For example, a circular garden that is 20 feet across has a radius of 10 feet. 10 x 10 x 3.14 = 314 sq. ft.

(The mathematical formula for the area of a circle is Π · r2 - the Π symbol is pronounced Pi and represents approximately 3.142, and r2 stands for radius squared.)

3. Find How Much Seed You Need

The amount of seed you should plant depends on the flower display you want. We typically recommend planting on the higher side for a lush meadow. Plant on the lower side for a more scattered look. 

For Individual Species: The recommended rates vary greatly from species to species. Check the product page, or contact us with questions.

For Wildflower Mixes: Reference the table below.

This Much Seed Covers... This Much Square Footage
1/4 lb 250 - 500 sq. ft.
1/2 lb 500 - 1,000 sq. ft.
1 lb 1,000 - 2,000 sq. ft.
5 lbs 5,000 - 10,000 sq. ft.
10 lbs 10,000 - 25,000 sq. ft.
  • 1 Acre = 43,000 sq.ft.
  • 1/2 Acre = 21,500 sq. ft.
  • 1/4 Acre = 10,750 sq.ft.
  • 1/10 Acre = 4,300 sq. ft.

Tips For Larger Plantings: If you have a large site, from 1/2 acre to several acres, your planting rate may be affected by land conditions. If you have heavy weeds on the site now, some erosion, generally poor soil, or other land problems, additional seed is usually the most economical solution, since installation of a large planting usually costs more than the seed itself. If your site does have these problems and you want full coverage, use 1 pound per 1000 sq. ft.
