You may know that the flower color of Hydrangeas is usually a result of the pH of the soil. If your soil is very acidic, your Hydrangea will likely produce more blue flowers. If your soil is more neutral or alkaline, your Hydrangea will likely produce more pink flowers. If you are unsure of your soil pH, you can buy a soil test kit at your local garden store.
If you prefer to have mostly blue and lavender flowers, you may add acidic soil amendment which will shift the pH. If you prefer to have mostly pink flowers, you may add garden lime to your soil which will shift the pH.
If your L.A. Dreamin® Hydrangea is blooming pink, blue and everything in between, and you like this multi-colored effect, then there is no need to amend your soil with any products.
If you want to shape your plant, it’s best to do so immediately following a heavy flowering (likely in June or early July). Light shaping won’t affect blooms for the following year.
If you want to remove spent flowers, you can do so at any time but you’ll need to be mindful about where to cut. For the best success, follow the guidelines below.
L.A. Dreamin’® is a macrophylla type Hydrangea. It will bloom on both new wood (this season’s growth) and old wood (last season’s growth), but the best flowering is on old wood. In more Southern climates, L.A. Dreamin’® Hydrangea is often a better re-bloomer.
