Water requirement: Medium
Prefers rich, moist soil.
There are 3 ways you can plant Aster: from seed, from stem cuttings and from division.
Start seeds indoors, sprinkle one or 2 seeds in starter pots half filled with soil, barely cover them (about 1/8"), place in indirect sunlight, keep moist (but not soggy), thin the seedlings when they have one set of leaves, keeping the stronger one. After the last frost, acclimate the seedlings outside (2 hours per day for the first 3-4 days), then tansplant the seedlings outdoors.
To divide, cut straight down through the roots, and re-plant the removed portion elsewhere.
