What to plant with hydrangeas – best varieties

When planting hydrangeas, it is important to consider the companion plants. Companion plants depend on the type of hydrangea you are planting. For example, if you are planting a Mophead Hydrangea, then you would want to plant a vine such as clematis or a morning glory nearby. Clematis will grow up the hydrangea and morning glory will sprawl across the ground.

In addition, it is important to consider the soil type when planting hydrangeas. They grow best in moist, well-draining soil but can tolerate a variety of soil types. If your soil is not ideal for hydrangeas, then try planting other varieties that will suit your soil type.

Quick Care Guide For Hydrangeas

Hydrangeas are beautiful woody deciduous shrubs that can be grown in a variety of settings. They grow well in both containers and in the ground, and they need rich soil with plenty of compost and leaf mold added. Be sure to keep it moist, especially during the heat of summer.

Mulching is a key part of taking care of your hydrangeas. The mulch will keep the soil cool and moist, which they need to thrive. In addition, hydrangeas are greedy feeders and need plenty of water during the growing season. You can feed them with fertilizer in spring to fall for the best results.

Finally, the flowers of the hydrangea are affected by soil pH levels. The color of the flowers will change depending on the pH level of the soil.

Why Do Some Hydrangeas Change Flower Color?

Some hydrangeas change color to pink in alkaline soils. Alkaline soil has aluminum and a pH level that is higher than 7.0. Flowers are naturally pink, but turn blue in acidic soils because of the presence of anthocyanins. Hydrangeas remain pink in alkaline soils because aluminum suppresses the production of anthocyanins.
