General Culture:
Asters prefer full sun and a rich well drained soil. To combat powdery mildew do not let the plants dry out during summers heat. If mother nature goes through a dry spell - provide a little extra water for your asters. Does well in sandy or clay soil. Generally tolerates poor soils and some drought. Pinching is not required due to compact size. Plants do not come true from seed, so consideration should be given to cutting back stems after flowering to prevent self-seeding.
