In order for your garden hydrangeas (Hydrangea macrophylla) to grow into magnificent bushes with a dense abundance of flowers, you should offer them the best possible starting opportunities with the right planting.

Plant your garden hydrangea in spring

Which location do garden hydrangeas prefer?

Garden hydrangeas prefer a sunny to lightly shaded location with mostly direct sunlight. A sheltered spot with light shade (e.g. under tall trees) without direct midday sun is ideal.

What substrate do garden hydrangeas thrive in?

Garden hydrangeas thrive best in acidic to neutral soil. Although alkaline soils are sometimes acceptable, you should try to avoid or reduce high pH values above 7.5. For the popular blue flower color of garden hydrangeas, in addition to a low pH value in the soil, special fertilizer containing aluminum is also necessary.

When is the best time to plant garden hydrangeas?

The ideal planting time for garden hydrangeas is spring to mid-May at the latest, when the soil is open. Container plants (i.e. garden hydrangeas grown in plastic pots) can also be planted during the summer months. In this case, however, you must water particularly carefully and extensively after planting so that the hydrangea is adequately supplied during the rooting period. Autumn planting is also possible, but should be done as early as possible, by the end of September at the latest. Then the plants have enough time to take root before the first frost.

What is the best way to plant garden hydrangeas?

Thorough loosening of the soil by digging is important before planting. In addition, the soil should be prepared in the previous autumn with green manure (e.g. phacelia or wild mustard) and lime. For planting, dig a sufficiently deep hole, which should be about one and a half times the root ball. Also enrich the excavation with mature compost and a handful of horn shavings (32.93€). Any grafting points must be about two to three fingers below the ground.

What planting distance should be observed for garden hydrangeas?

When determining the planting distances, you should keep the growth performance of these shrubs in mind. Although garden hydrangeas hardly get higher than one and a half meters when they are old, they form compact, dome-shaped shrubs. So give the shrubs enough space to develop into well-proportioned, even shrubs.

How can I propagate my garden hydrangeas?

Garden hydrangeas are best propagated via layering or summer cuttings.

When do garden hydrangeas bloom?

The main flowering time for all garden hydrangeas is in July; for some, flowering begins as early as mid-June or extends into September. Since the flowers wither in a very decorative way, they convey a much longer "perceived" flowering time overall.

tips and tricks

You do not need to cut off the dry inflorescences of garden hydrangeas, instead they are a special ornament in winter, especially when they are "covered" with hoarfrost.
