How to Propagate Tall flat-topped asters?
Propagating tall flat-topped asters is commonly achieved through seeds, cuttings, or division. Key factors for success include adequate light, correct temperatures, and well-draining soil. Special considerations involve stratifying seeds if necessary and ensuring cuttings are taken from healthy, disease-free plants. Propagation of tall flat-topped asters is moderately easy, with potential difficulties being stem rot in cuttings and seed dormancy. To propagate by division, follow these steps: 1) In late fall or early spring, dig up plant clumps. 2) Gently separate the clump into smaller sections, ensuring each has roots attached. 3) Replant the sections immediately at the same soil depth, spacing them about 18 inches apart. 4) Water thoroughly and provide consistent moisture as new plants establish.
