New England Aster Care

Size & Growth

The plant is a fast grower, especially when all the necessary growing conditions are met thoroughly. 

With self-seeding and division every couple of years, the plant grows aggressively.

It has the potential to grow up to 6’ feet in height and have a 2’ – 3’ feet width. 

Additionally, it is easy to grow and care for and is long-lived, making it a perfect addition to cottage gardens and meadows where other wildflowers also grow in abundance. 

Flowering and Fragrance

The flowers of the New England Aster plant are its most attractive feature. 

Daisy-like, the flowers grow in abundance and make excellent cut flowers to put in bouquets and table settings.

They grow in lovely clusters and are about 1” – 2” inches in diameter in shades of violet or lavender. 

The blooms have rose-purple, lavender or white ray florets with orangish-yellow centers.

Flowers appear on sturdy stems during the fall. 

They are the brightest and most beautiful under the sun. 

When it gets dark at night or on a cloudy day, the flowers droop. 

You will see them pursuing their glorious display when the sun starts shining the next day.

Light & Temperature

The plant is native to eastern North America and is hardy to USDA zones 4 to 8. 

Since the plant blooms in the fall, it prefers a mildly cooler climate.

As for light, the plant loves to bask in full sun. 

But it can also survive and flower well when planted in partially shaded locations. 

Watering and Feeding

New England asters have average watering needs. 

It does love moist well-drained soil despite being drought resistant. 

Then the weather starts getting warmer, check the soil to make sure it doesn’t dry out completely.

You also need to be careful about overwatering. 

Too much moisture may lead to wilt and root rot.

Soil & Transplanting

The plant is not picky when it comes to soil and thrives in average light to medium soils. 

The plant grows in heavy clay soil but doesn’t care for it. 

Heavy soils with poor drainage can lead to Aster wilt.

Choose well-drained soils with capabilities to sustain medium moisture. 

Rich soils are also preferred for healthy growth.

The plant is not particularly fond of transplanting. 

Division is done once every other year to keep the growth going strong. 

Grooming and Maintenance

The Aster novae-angliae daisy is a low maintenance plant. Pruning is not required. 

If flower growth is overwhelming, cut the flowers for a table bouquet.

Before midsummer arrives, cut the stems back. 

This will allow for bushier foliage, increased flower production, and height control, which prevents the plant from flopping overgrowth.

The plant is self-seeding, and it grows rapidly. 

If you want to curb the growth and prevent self-seeding, cut back the growth after the plant flowers.

Taller plants may require staking or other support to stay upright and not flop over.
