This article will break down the process of growing and caring for lovely New York asters.

New York asters are similar to daisies with starry-shaped flowerheads that range in color from white to blue to purple. They bring beauty to your garden in late summer and autumn when many other blooms are fading.

They come in various heights ranging from 8 inches to 8 feet and are versatile plants that can thrive in many places, including rock gardens, borders, and wildflower gardens.

In this article, I will detail the process of aster flower gardening and care. Before I begin, let’s get to know about them in brief.

All About Asters

Asters are also called Michaelmas daisies, referring to the holiday with the same name that happens annually on September 29.

These beauties are eye-catching in every way and come in a few species and varieties. The two most common asters are the New England aster (Symphyotrichum novae-angliae) and the New York aster (Symphyotrichum novi-belgii). You can find them in a range of hybrid varieties available in the flower market.

Asters don't just attract humans, but butterflies and bees as well with their charming blooms. They provide pollinators with late-season supplies of nectar to flower insects. The wild-type species are native to New York and other nearby regions.

Aster novi-belgii is a beautiful, daisy-like flower perennial with lance-shaped leaves that clasp the stem. Its large flowerheads are arranged beautifully in showy panicles. It has white ray florets at a central cluster and yellow disc florets.

Planting Tips

  • Though they are evergreen flower plants, asters prefer climates with cool, moist summers and cool, windy, and twilight temperatures.
  • In warmer climates, you should avoid planting them in the hot mid-day sun.
  • The soil of the site should be moist but loamy and well-draining.
  • Use mix compost into the soil before planting.

Planting Aster Seeds

  • If you plan to plant New York aster seeds, keep in mind that germination can be uneven. So, it is suggested to start sowing seeds in flat pots. They need four to six weeks to simulate, especially in the winter season.
  • Sow seeds at least 1 inch deep in the soil in a sunny spot in your garden.
  • The best time to plant a young New York aster flower is in mid-to-late spring, though you can still plant fully grown asters in your garden in the fall.
  • Give them enough space to thrive—anywhere from 1–3 feet, depending on the type and size it gets.
  • Be sure to give plants enough water at the time of planting.
  • To keep the soil cool and prevent weeds, add mulch after planting.

Care Instructions

  • After planting, add a thin layer of fertilizer to the soil of the New York asters.
  • If your region gets less rain, remember to water your plant regularly in the summer.
  • Many asters are moisture-sensitive, however, and don’t like too much watering or too little watering. It forces them to lose their lower foliage or stop growing. So keep an eye on them and try a different watering process if the plants are losing flowers.
  • Arrange the tall varieties of asters mindfully to keep them from falling.
  • Pinch back asters once or twice in the summer to promote blooms and bushier growth.
  • Cut them back in winter if you find the foliage has died.
