Multiply Hollyhocks - It's easy to grow new plants


Anyone who has ever had hollyhocks in their garden is guaranteed not to want to do without them again. So it's good to know that multiplying is a breeze.

Hollyhocks reproduce themselves through seeds

Multiplying hollyhocks (Alcea rosea) is one of the simplest tasks in the garden. Propagation via seeds works so well that you no longer need to deal with cumbersome methods. You can get the seeds for many different varieties of hollyhock in any gardening store and also online (e.g. here).

But the best thing about hollyhocks is that once they have bloomed, you always have seeds free in your own garden.

❀ Sow hollyhocks in the garden

Sowing the hollyhocks in the garden is recommended between May and September. To do this, proceed as follows:

1 Simply lay the seeds on the ground and cover them with a little damp soil. Keep a distance of 40 to 60 cm. However, you can also sow more densely and then leave only the strongest and most beautiful specimens.

2 If possible, choose a sunny location to ensure ideal plant growth.

3 Hollyhocks need a temperature of around 20 degrees Celsius to germinate. After a short waiting period of two to three weeks, the first leaves can be seen. Hollyhock does not have any special demands on the soil.

4 In the second year, you can put a little humus around the plants in spring to ensure a good nutrient supply. Cultivation in a bucket as an alternative to the bed is also possible. Choose very tall containers for this, as the hollyhocks form deep tap roots.

❀ Advance and expose hollyhocks in the house

As an alternative to sowing in the garden, hollyhocks can also be brought to a bright location in February or March in the house or greenhouse. With a little luck, flowers that grow from these early seeds will bloom in the first year.

After sowing in the garden in summer or autumn, on the other hand, you have to wait a year to enjoy lush inflorescences. Use ordinary plant pots for growing and put the young hollyhocks outdoors at the end of May.

❀ Wait for self-propagation and move young plants

After the hollyhock blooms, the dried inflorescences fall off and release the seeds so that new plants grow on the spot. You can let this natural self-reproduction run free or move the young plants to a desired location.

Here's how:

1 Use a spade to prick the soil around the hollyhock deeply and inwards from all sides. This gives you a compact block of earth with the root system of the plant that tapers to a point.

2 Lift this block out as a whole and place it in a prepared hole in the floor at the new location.

" My advice: The young plants grow particularly well in sunny and sheltered locations such as a south-facing house wall.
