Winter and Your Hydrangeas
If you’re a cold-climate gardener like I am, you’ve probably thought about how this (seemingly never-ending) winter will affect your hydrangeas.
The good news is that all the snow cover is a great insulator, and if we keep a heavy coating of snow while temperatures remain cool, and there are no late-spring frosts, you may see an amazing display from your plants. This is because the snow is protecting last year’s flower buds from the worst of the cold temperatures.
The bad news, like I mentioned last week, is that the snow has robbed deer, rabbits, and other critters of many of their usual winter foods, so they may be eating away at your plants.
If you live in a more mild climate and your winter has been unseasonably cold, you may not see your usual display if the chilly temperatures damaged the flower buds.
That is, of course, unless you grow reblooming varieties such as Endless Summer, Penny Mac, or the Let’s Dance series from Proven Winners — these varieties are famous for being able to make new flower buds for summertime blooms.
Or have summer-blooming types such as ‘Annabelle’, ‘Limelight’, etc., they may not be affected by the cold because they don’t start producing their flower buds until spring anyway.
