AboutMike Mascio Expertise I have been an avid gardener since 1985 and an AllExpert volunteer since
1998. I specialize in soil preparation, seed starting and plant
propagation, flowers, vegetables, and general landscaping. I am a strong
advocate of the square foot method of gardening and the use of organic
controls for pests and diseases.
Question My snowball is very healthy looking, but it didn't bloom this year. why?
Answer The primary reason a perennial will not bloom is damage done to the buds due to a late frost. The plant will still thrive, but it will not bloom. The other factor is soil conditions. If the soil is lacking phosphorus, the nutrient required for blooming, the plant will produce lush foliage but no blossoms. To correct this problem, you need to fertilize the plants in early spring with a product high in phosphorus.
I hope this answered your question. Please write again if I can ever provide assistance.
