Question I live on Long Island, NY and have several hydrangea bushes. They have always bloomed each season. This year my hydrangeas didn't bloom. All I got was the green leaves. I noticed many hydrangeas in my area also did not bloom. What's going on?
Answer Hi Jewel,
Thanx for your question. It depends upon what type of hydrangea you have. If you had any kind of cold snap this spring, that could have done the blooming buds in, especially if you notice other folks' hydrangeas did not bloom either. It's usually because a cold snap killed the buds. Another thing is to avoid trimming the shrubs back too late. They can be trimmed right after blooming but don't wait too long or you'll be trimming off next year's buds. Too much nitrogen from lawn treatments can result in heavy green growtha and no blooms as Nitrogen in the lawn treatments results in very good leafy growth at the expense of blooms. Other than that, the other thing you may want to do is check with the local Country Extension Agent to see if there were any invasive pests recently introduced or otherwise attacking hydrangeas. If you want a contact, give me your county and I'll set you up. I hope this helps.
I have been a gardener for 20 years with perennials both growing from seed and from nurseries. I went through the Master Gardener Program from Kansas State University Cooperative Extension Service and I answered questions on the Hotline a few years ago for the Wyandotte County Kansas Extension Service. I have also lived in the Florida, California, Hawaii, Arizona, Texas, Kansas and Missouri and am experienced with a variety of climates, soils and weather conditions.
I have been growing perennials for over 20 years now. I am self-taught mostly except for a master gardener class. I have experimented with all kinds of perennials including many that are not common to my area. I have read hundreds of books and grown hundreds of varieties of plants and hope to make it a business some day. I have become versed in botanical names and growing conditions and what I don't know off of the top of my head I can usually easily find in my vast array of research material and botanical and horticultural contacts. I especially enjoy experimenting with growing plants out of zone.
