Asters are most easily grown by splitting an existing clump in early spring, as the plant starts into growth or late autumn after flowering. Loosen the whole clump using a fork and dig up with roots and soil attached. Split the clump with a spade or leaver apart with two garden forks, back to back. Aim to have roots and stems with attached soil. Replant each clump, about 0.5m apart, firming in and water well
Soft wood cuttings in spring will also grow well
Asters flower best if clumps are divided regularly every year
