|My hardy mums never last through the winter. What is the best way to make them bloom year after year?
|Although it s possible to get hardy mums to overwinter and begin growth again in the spring, they generally won t put out as many flowers in subsequent years--and certainly nothing like they have at the garden centers, where they re nurtured for that spectacular fall display.
Once the foliage dies back, you can trim it to about 6 inches. After the soil freezes, mulch the plant heavily (6 or more inches) with straw or bark chips. Remove the mulch in the spring.
