Are coming in beautiful but no blooms! My neighbor offered some food that a sprinkled around the drip line according to instructions. Now I see white cotton substance growing on the fertilizer. Is this normal? Help!

Welcome! Do you know what kind of fertilizer it was? Is it possible to post a picture of the cottony stuff? Hydrangeas that bloom on old wood won't flower if they were pruned late in the preceding year or if winter killed the flower buds. Other hydrangeas do flower on new wood produced after winter, and some can do both. I assume from your user name you are in Ohio? Fertilizing isn't going to make them flower this year if there is no sign of flower buds by now. Do you know what kind of hydrangeas they are?

Hi and welcome. If you would please fill in your profile to show your location, that will help us to help you. Just a zone doesn't cut it because it won't tell us anything about your general weather conditions during the growing season.

The most common reason for hydrangeas not blooming is that they were pruned too late in the fall, or in spring. If you did that, you've cut off all the growth from last summer that would have bloomed this year. For future reference, they need to be pruned right after they are finished blooming, then let to grow out through the fall to develop blooms for the next year.

As far as the fungi growing on the soil surface, it's usually not anything to worry about. Let the top of the soil dry out and it will disappear.

Yes, I'm in Ohio and the hydrangeas are from Jackson & Perkins:
Everlasting Ocean
Everlasting Amethyst
I also have an Invincibelle Spirit in the middle and it's growing out of control with a ton of blooms. We did have a late Spring freeze this year. Thank you for the replies
