Hydrangea Care Guide: Expert tips for growing confidently
With their showy flowers, lush foliage, and striking color choices, it's no wonder that hydrangeas are favorites of gardeners across the country (and across the pond). But we've found that many gardeners feel stumped when it comes to how to best care for their hydrangeas. For some, hydrangeas have gotten a bad reputation for being fussy.
1. Planting Hydrangeas
If we had to pick, we'd say fall is the best time to plant hydrangeas. Planting in fall gives ample time to develop a healthy root system before the burst of growth that will come in spring. The longer and colder your winter, the earlier in fall you'll want to plant.
2. Deadheading and Pruning Hydrangeas
Yes (but you don't have to). The most common form that your snipping will take when it comes to caring for your hydrangeas is deadheading, which is not technically "pruning." Deadheading your hydrangea can increase bloom and help keep your hydrangeas looking neat, but you also don't have to deadhead in order to keep your plant healthy.
3. Fertilizing Hydrangeas
Different hydrangeas have different needs when it comes to fertilizer. A good "rule of thumb" fertilizer suggestion for all hydrangeas is to fertilize them with a well-balanced fertilizer in early spring. Adding a layer of compost and mulch will benefit your soil health, and in turn, your hydrangeas.
4. Watering Hydrangeas
Water your hydrangeas in the morning before the heat of the sun is strong enough to quickly evaporate soil moisture. Try to avoid watering at night, which can encourage mold and mildew as the moisture sits through the cool night. Water your hydrangeas through the growing season as well as in late fall.
5. Changing Hydrangea Flower Color
The science of changing hydrangea color comes down to soil pH. So, in order to change the color of your hydrangea flowers, the first thing you need to do is get a soil test to see where your soil lands on the pH spectrum. Then, based on your soil pH and your desired flower color, follow the steps below.
