Stokes' aster

Stokes’ aster should be watered once a week during the spring and summer, when they are actively growing. Aim to provide them with enough water for the soil to be consistently moist but not wet. During the hotter months, the plant may need additional water if the soil starts to dry out earlier. In the winter, water the Stokes’ aster less frequently, but still make sure to check the soil for moisture. It shouldn’t need watering more than once every 2 weeks.

Stokes' aster (Stokesia laevis 'Mary Gregory') thrives best in a sunny spot with at least 6 hours of direct sunlight every day. This hardy perennial is tolerant of heat and drought, but will not tolerate extended periods of shade. Aim to provide Stokes' aster with all-day sun, but if your garden is in a somewhat shady location, try to provide as much direct sunshine as possible, particularly from the late morning to the late afternoon.

Stokes' aster (Stokesia laevis 'Mary Gregory') should be pruned in the early spring once the danger of frost has passed. Pruning should remove any dead or damaged stems and any foliage that has become diseased or weakened over the winter. For aesthetics, also remove any stems that have become overgrown or overcrowded the previous season. Trim back the stems of this aster by 1/3 to 1/2 of their length. This will stimulate and thicken new growth and prevent the plant from becoming leggy or producing fewer flowers.
