Callistephus chinensis Matsumoto Light Blue seeds - China aster

Sowing Matsumoto Light Blue Shasta Daisies: It is best not to sow these plants in the same location for two consecutive years. Sow outdoors from April to May, then transplant into position as soon as the young plants have 2 to 4 leaves, spaced 40 cm apart, in well-loosened, moist, and well-manured soil, choosing a sunny spot. Water frequently, but sparingly. It is beneficial to transplant several times while keeping the root ball intact to encourage root development and slightly restrain stem growth, which might otherwise break under the weight of the flowers. For earlier flowering, sow under a frame or on a hotbed, in trays, from February to April. Sow Shasta Daisies in trays filled with sand and peat under shelter at a temperature of 16 to 20 °C. Transplant into individual small pots when the seedlings have at least four leaves. Plant them out in the garden when they reach a height of 15 cm. Use stakes to support the taller varieties with very double flowers.

A later sowing in June allows for staggered flowering until the end of autumn. This sowing can be done directly in place in the garden.

These plants prefer a neutral or slightly chalky, fertile, and well-drained soil and require a sunny exposure. Generous watering will be necessary twice a week during dry periods, but take care to water the base and not the foliage, as Shasta Daisies are susceptible to powdery mildew. Remember to remove faded flowers as they appear to prolong flowering and prevent the plant from weakening.
