Hydrangea Leaves Stuck Together

Why are some hydrangea leave stuck together?

Take a look at your ‘Annabelle’ hydrangea and any other hydrangea arborescens you may have like Incrediball® or Invincibelle® Spirit. You may notice some of the leaves stuck together and cupped. It looks like these leaves on my Invincibelle® Spirit.

Pretty interesting, huh? Don’t panic!


Hydrangea leaves get stuck together when leaf rollers set up house to rear their young in the cocoon they create. This first hydrangea insect to show up is a normal and predictable occurrence. If you leave things alone, your plant will be fine.

I explain why your leaves are stuck together in detail in my book, Success With Hydrangeas, A Gardener’s Guide. It can be very helpful to know what to expect so you can be prepared to handle insect issues so I devoted an entire chapter on insects and diseases of hydrangeas. Knowing what to do about these issues is a sure way to have healthy plants. Scouting and preventive maintenance will assure you have plants that look stunning in your garden this season and for years to come.


Success With Hydrangeas, A Gardener’s Guide is all about how to grow hydrangeas. It’s an international best seller with rave reviews which you can read on Amazon. Conveniently, that’s also where you can purchase the book. On the other hand, if you want a signed copy, just go to my website to do that, especially for a Father’s Day gift. The site will also tell you about me, where I am giving talks and how to sign up for blog posts if you are not already a subscriber. Plus you can catch up on prior blog posts.


If you are close to Danbury, CT. come to the free talk I’m giving at Stew Leonard’s Garden Shoppe on June 9 at 1 p.m. Afterward, you’ll be able to buy signed copies of my book .


Last but not least, in my next blog post I’ll write about which of my hydrangeas are set to flower this month despite a really frigid Connecticut winter. I’ll discuss what I did to make that happen. In short,  unlike 2017 not all of them have buds.
