#ProPlantTips for Care:

Requiring full sun, Purple Dome can take some afternoon shade in the hottest of its favored USDA growing zones of 4 through 8. Plant these herbaceous perennials in a moderate soil range with good drainage. Tolerant of lower moisture to average moisture environments once established, Aster should not be allowed to become extremely dry during the summer. Pinching back the stem tips in late spring and early summer will produce denser growth and heavier blooming. This plant may be divided every few years in the spring.

Lovely blooms

I thinned my purple dome asters out some this past year in the hopes to get a little bigger flowers. They were getting so thick and I think they were over crowded. Lots of flowers though!

Dear Diane,

Thank you so much for sharing your experience with your Purple Dome New England Asters! It’s wonderful to hear that your thinning efforts encouraged lots of lovely blooms—crowding can definitely make it tough for flowers to reach their full size. You did a great job by spacing them out, which helps air circulation and allows each plant to thrive.

For an even bigger floral display next season, you might consider deadheading spent flowers regularly to encourage continuous blooming, and making sure they’re planted in well-draining soil with plenty of sunlight. These asters typically love full sun and benefit from consistent moisture without being waterlogged.

If you’d like, we also have care guides and planting tips on our site that could help you optimize the health and size of your asters in the coming years.

Thanks again for your thoughtful review and happy gardening!

Lovely blooms

Hi Diane,

Thank you so much for sharing your experience with your Purple Dome New England Asters! It sounds like your thinning strategy was right on track—overcrowding can definitely limit how large and vibrant the flowers get. You did a great job giving your plants the space they need, and we’re thrilled to hear you still enjoyed lots of lovely blooms!

For continued success, a good tip is to thin asters early in the season by selecting the healthiest, strongest stems to grow out fully. Also, ensuring consistent watering and light feeding can boost flower size and overall plant health. If you need any guidance on fertilizer options or watering schedules, please don’t hesitate to reach out.

Thanks again for your thoughtful feedback. We’re rooting for your asters to blossom their brightest year after year!
