Today, we decided to devote the entire mail bag segment to this question which is surely on many people’s minds right about now. It is hydrangea season, after all, and we know how confusing it can get when you have high expectations for your plants and they disappoint.  Before we get into the nuts and bolts of the issue, it’s important to keep in mind that if your hydrangea was just planted last year, it’s not necessarily surprising it’s not blooming. First of all, because when you buy a hydrangea from the garden center, it will bloom much earlier that year than after it spends a year in your garden because the grower will have brought it into warmth much earlier in spring than it will experience in your yard. Second of all, sometimes hydrangeas need a little time to get established before they will bloom well.  The real key to understanding why your hydrangea isn’t blooming is knowing which hydrangea you have in the first place. That’s why we created Hydrangeas Demystified.
