What Are New York Asters?
With their daisy-like appearance and vibrant colors, New York asters add a pop of beauty to any fall landscape.

These deer-resistant flowers are perfect for rock gardens, cottage gardens, and coastal landscapes. All they need is a sunny spot with well-draining soil to thrive.
New York Asters Care
Here are the main care requirements for growing healthy and beautiful New York asters:
Light
To ensure your New York asters bloom to their full potential, place them in a sunny spot where they will receive at least six to eight hours of sunlight every day. While they can tolerate some shade, they won’t produce as many impressive flowerheads.
Soil
New York asters are adaptable to various soil types, but they prefer well-draining soil rich in organic matter. Sandy, loamy, or clay soils can all support these plants, but fertile, loamy soil will help them thrive and produce prolific blooms.
Water
These plants are relatively drought-tolerant, but they don’t like to be left dry for too long. Keep the soil evenly moist (but not soggy) to promote healthy growth and vibrant flowers.
Temperature and Humidity
New York asters prefer temperate climates and average humidity levels. Extreme heat or cold can cause wilting, but these plants are resilient and can bounce back once temperatures stabilize.
