My mums that I planted last fall are blooming and summer just started. I wanted flowers in the fall. Now what should I do?
To prevent those mums from blooming late spring early summer, pinch them back and do not allow flower buds to form. This also helps keep the plants short and stocky, not floppy. The last pinch should be around July 15, to allow flower buds to form and bloom in September and early October. If they have buds now or are flowering, cut them back right away, feed them, and maybe they’ll set buds again for September flowering.
