When applied to the ground around your hydrangeas, it will briefly raise the pH in a narrow zone – and then disappear with the next watering or rain.

If grown in pots, it is usually best to pick a dwarf variety in order to accommodate growing needs.The best time to plant hydrangeas is early fall or spring, depending on your region. In areas with mild winters, planting in September or October allows the roots to establish before winter dormancy. In colder climates, it’s better to plant in early to mid-spring (April or May) after the risk of frost has passed.One of the best times to plant hydrangeas is in the fall – this gives time for the roots to get established before any harsh weather sets in.However, most varieties of hydrangeas take two to four years to mature to full size.

Not all plants pair well with hydrangeas. Here are some combinations to avoid: Sunflower prefers full sun and hotter conditions than hydrangeas, which require some shade. Lavender is a sun-loving perennial that performs best in dry conditions and leaner soil, so will not thrive near hydrangeas.Many hydrangea bushes prefer some shade, especially in warmer climates, however, there are cultivars that can not only tolerate sun but also thrive in it. We have versatile hydrangeas that can grow in full shade or full sun.Hydrangeas that are grown in more sun than they like will often flag on hot days. They may recover at night, but if they continue to wilt every day, they may become stressed, making them more prone to damage from pests and diseases. And they’ll look tired with drooping flowers that often don’t attain full size.These shrubs are rapid growers, averaging two feet of growth per year, and their blooms can last all summer and into fall.

Most dried hydrangea flowers break off sometime in the winter and any that remain on the plant can be removed in the spring. Don’t “neaten them up”!When hydrangeas grow lots of leaves but no flowers, it is often due to excessive nitrogen in the soil, which encourages foliage over blooms. Insufficient sunlight can also cause lush growth without flowers, especially in varieties that need 3-4 hours of direct light.

This timing will vary by region. For instance, in areas with winter freezing and snow, hydrangeas should be planted in early spring or early fall (as soon as summer heat breaks). In warmer regions with mild winters, the window for planting hydrangeas is longer, from fall all the way through to early spring. Hydrangeas lose their leaves in autumn or early winter and grow best in temperate and cool climates with warm dry summers and cool winters.Hydrangeas are perennial plants, meaning they can live for several years or even decades.
