Common Questions
Are hollyhocks hard to grow?
Hollyhocks are low-maintenance and easy to grow. They just need fertile soil, plenty of sun, and appropriate spacing and moisture levels to prevent problems with the fungal disease rust.
My hollyhock plants have a sickly appearance, what should I do?
If your hollyhocks appear stunted and feeble, they may be affected by the Puccinia malvacearum rust disease. This disease manifests as yellow or orange spots on the leaves, which later develop into lumps, causing the foliage to wither and fall off. Promptly eliminate the infected plants and dispose of them securely in a sealed bag.
My hollyhock’s leaves are curling, what is wrong?
Curling hollyhock leaves could indicate that the plant is under heat stress due to intense sunlight. To remedy this, consider relocating the plants to a shadier spot or installing a shade cloth for protection. Additionally, adding mulch to the soil can help maintain cooler roots for the plant.
Do I need to deadhead my hollyhock flowers?
Yes, to prolong your bloom season you will need to deadhead spent flowers. Also keeping your plants consistently moist will help encourage a good bloom season.
What are some good companion plants for alcea?
Plants such as salvia, echinacea and shasta daisy all work well with the alcea hollyhock plants.
