Hollyhocks are a stunning addition to any flower garden, with their beautiful blooms adding a touch of elegance and charm. While they are generally easy to care for, knowing how to properly prune them is essential for maintaining their health and ensuring abundant blooming throughout the season. But should hollyhocks be pruned? If so, when and how should it be done? And what about trimming them in autumn? In this article, we will explore all of these questions and provide you with a comprehensive guide to pruning hollyhocks.
Should hollyhocks be pruned?
Whenever I think of summer, I am reminded of my grandmother's garden adorned with the vibrant blossoms of her hollyhocks. She has a deep fondness for these plants, which she refers to as “medicinal,” as she often uses their flowers to prepare tea. However, on a recent visit, I was surprised to find her pruning her hollyhocks. Curious, I asked her why she was doing so. As someone who also cultivates these plants in my own garden, I was eager to learn more about the importance of pruning hollyhocks.
Hollyhocks are perennial plants that are often grown as biennials. Once established in your garden, they have a tendency to return year after year and can even become invasive due to self-seeding. However, pruning hollyhocks is not a necessity. That being said, if you wish to extend their blooming period well into late summer, it is highly recommended to prune them. Additionally, removing faded flowers can prevent self-seeding and the invasive spread of hollyhocks, as my grandmother informed me.
When should hollyhocks be pruned?
So, when is the best time to prune hollyhocks? Well, there isn't exactly a specific ideal time for pruning. Hollyhocks typically bloom from June to September, and once their flowers have wilted, you can cut the stems at the base to encourage further blooming.
When autumn arrives and the hollyhocks begin to die off, you can trim the stems a few centimeters above the ground. This will help tidy up your garden and prepare it for new spring flowers. However, if you want the hollyhocks to self-seed, allow the faded flowers to remain on the plant until they turn brown and shed their seeds naturally. Alternatively, you can collect the seeds yourself and sow them in the soil for future growth.
How to prune hollyhocks after flowering to encourage blooming
Pruning hollyhocks differs slightly from other plants that produce only one flower per stem, as the buds do not all open at the same time. To maintain a neat and tidy appearance in your garden, you can simply remove the faded flowers from the stems.
However, if you want to encourage blooming, my grandmother shared with me her technique of cutting the entire stem of the flower at the base once the majority of the flowers have faded. Here is a step-by-step guide on how to do it:
- Observe the plant's flowers closely. When you notice that they are losing color and falling off, it's time to take action. Remove them so that the plant can conserve its energy for producing new flowers.
- If you want the plant to self-seed, leave a few faded flowers on the stems or collect the seeds to sow them yourself.
- In autumn, thoroughly trim the plant using pruning shears, leaving only a few centimeters above the ground.
- Remove any damaged or dead shoots as well.
How to prune hollyhocks for winter
Pruning hollyhocks for winter is different from simply removing faded flowers to promote better blooming. If you want the plants to drop their seeds for the next year, it is important to leave the faded flowers on the stems so that they can release them. Once the seeds have fallen, you can then cut the plants at the base, regardless of whether the leaves are still alive or dead.
Pruning hollyhocks is not a necessity for having a beautiful plant. They will grow beautifully and healthily even without pruning. However, pruning can encourage more abundant blooming by preventing the plant from diverting energy into seed production. Additionally, it will give your garden a cleaner and more attractive appearance. So, why not give it a try?
