Winter Hollyhocks - How to get the plant through the cold season unscathed

Bringing hollyhocks over the winter is not that difficult. In fact, it's actually quite straightforward. You should only consider a few things for hollyhocks planted in tubs.

Hollyhocks easily survive the winter in the bed

The good news first: Hollyhocks (Alcea rosea) are frost hardy. Adult plants survive the winter in our latitudes practically without damage. Young Hollyhocks also have excellent chances of survival without any further action.

With potted plants, however, there is a risk that the hollyhocks will die of thirst during the winter. In addition, strong winds can affect the tall plants. But if you act in time, you don't have to have any concerns here either.

❀ Hibernate adult hollyhocks in the bed

If your full-grown hollyhocks are in the bed, you do not have to worry about winter and do not have to take any special measures to protect the plants. The Hollyhocks will most likely not suffer frost damage.

Unless you want to prune the plants, the deepest winter is not the best time. It is better to prune in autumn after flowering or in spring from March. A pruning is not absolutely necessary, but it can ensure a slightly better growth of the Hollyhocks next year.

❀ Hibernate young plants

If you don't pick up the fallen inflorescences of your hollyhocks in late summer and autumn, the plants will reproduce independently through the scattered seeds. The young plants usually survive the winter as well as the larger specimens. If you want to be on the safe side, cover the small hollyhocks with brushwood or fir branches in late autumn.

Hollyhocks that you prefer in the house or greenhouse from February will be released outdoors in the second half of May. After the ice saints in mid-May (mostly) there is no longer any danger of frost in Germany.

❀ Hibernate hollyhocks in tubs

If your hollyhocks are not in the bed, but in tubs, you must make sure that the plants do not die of thirst in winter. This can easily be done if the tubs are protected under a canopy and neither snow nor rain reaches the plants. Use the frost-free days in winter to ensure the water needs of the plants by watering.

But don't overdo it: waterlogging is just as unhealthy for hollyhocks as long-lasting dryness.

❀ Don't forget the windbreak!

Also ensure adequate wind protection. Hollyhocks reach a total height of up to two meters. Some varieties reach heights of three meters. There is a high risk that the plants will snap off due to strong wind or fall over with the tub. Protect your hollyhocks by tying the plants or by placing them on a sheltered side of the house near the house wall.

If you take into account all of our tips, there will be nothing standing in the way of your hollyhock next year.
