Choose the right location and substrate
Before planting, however, you first have to choose the right location and substrate - both are essential for the well-being of your plants. Hanging geraniums need a lot of sun - the sunnier their location, the more flowers you can expect. At the same time, however, the plants should be protected from adverse weather conditions. Frequent rain, in particular, causes the flowers to become unsightly. In terms of substrate, you should choose a nutrient-rich and well-drained soil. Special geranium soil, for example, is very suitable, but you can also mix it yourself:
- 1 part of standard potting soil
- 1 part compost soil
- 1 part perlite (32.90 € at Amazon *) (or another clay granulate)
- Tyrolean hanging geraniums - care, cutting, wintering

Match the optimal time
The correct timing of planting is also extremely important for hanging geraniums; they do not tolerate frost and should therefore be planted after the ice saints at the earliest. Before doing this, it makes sense to only put the plants outside during the day to harden them and bring them into the house overnight. The right temperature is also crucial, because hanging geraniums stop growing at less than 10 ° C. The plants prefer a lot of warmth during the growing season.
Ensure good drainage
If the three important questions - location, substrate, timing - have been clarified in advance, you can now plant the hanging geraniums. The drainage in the planter is one of the most important points, after all hanging geraniums do not tolerate waterlogging.
- Choose a planter with drain holes to allow excess water to drain away.
- Thoroughly clean the planter.
- To keep the drain hole from clogging, you can put a fleece over it.
- First, pour a layer of drainage several centimeters thick on the ground.
- (Small) pebbles, expanded clay (€ 17.50 at Amazon *) or clay granules are suitable for this.
- Now fill in the geranium soil.
- Carefully remove the hanging geraniums from their current planters
- and plant them every 20 centimeters.
- Press the earth well
- and water the plants thoroughly.
If the geranium soil is pre-fertilized, fertilizing is not necessary for the next six to eight weeks.
Hanging geraniums are often wrapped with a supportive plastic rack. In order to free the plant from it without damage, you should cut open the struts all around.
