Hydrangeas have high demands on the soil in which they thrive. A loose mixture of peat and compost is very suitable. Alternatively, you can improve the soil with rhododendron soil, the pH value of which is in the slightly acidic range that is optimal for the hydrangea.
Water regularly

Hydrangeas in open ground need regular fertilization
Like all garden plants, the outdoor hydrangea also needs regular fertilization. Special fertilizers that you can get in specialist shops are high in nitrogen and low in phosphorus. Alternatively, you can also use azalea or rhododendron fertilizers. Horn shavings (€ 6.39 at Amazon *) or horn meal mixed with humus not only improve the soil quality, they also provide the hydrangea with all the trace elements it needs.

If these are removed when cutting, the hydrangea only leaves leaves in the following year and does not have any flowers.
