From Ground: First, water the tatarian aster plant to dampen the soil. Gently dig around the plant 6-12 inches away from the stem using a spade or shovel. This is done to preserve as many roots as possible to ensure successful transplanting. Once the plant is loose, gently lift it from the ground.
From pot: Water the tatarian aster plant adequately. Turn the pot upside down, holding the plant at its base with your fingers spread on each side. Gently tap the pot’s rim on a hard surface to loosen the root ball and carefully slide the plant out of the pot.
From seedling tray: The tatarian aster plant is usually ready for transplanting when it has at least two sets of true leaves. Moisten the soil and carefully lift the seedling out, holding them by their leaves to avoid damaging the stem or roots.
