Growing Hollyhocks: A Beginner’s Guide
Introduction
Hollyhocks are impressive flowers that can add height and drama to any garden. They are relatively easy to grow, but there are a few things you need to know to get started. In this guide, we will cover everything you need to know about growing hollyhocks, from planting to care and troubleshooting.
Planting Hollyhocks
- When to plant: Hollyhocks can be planted in the spring or fall. If you are planting seeds, start them indoors 6-8 weeks before the last frost. If you are planting seedlings, wait until 2-3 weeks after the last frost.
- Where to plant: Hollyhocks prefer full sun and moist, well-drained soil.
- How to plant: If you are planting seeds, sow them 1/4-inch deep in the soil. If you are planting seedlings, dig a hole that is twice the width of the root ball and just as deep. Place the seedling in the hole and fill it back in with soil, tamping down gently to remove any air pockets.
Caring for Hollyhocks
- Watering: Hollyhocks need regular watering, especially during hot, dry weather. Water deeply at the base of the plant, avoiding the leaves.
- Fertilizing: Hollyhocks benefit from being fertilized in the spring with a balanced fertilizer.
- Mulching: Mulching around hollyhocks helps to retain moisture, suppress weeds, and regulate soil temperature.
- Deadheading: Deadheading spent blooms encourages new growth and flowering.
Common Hollyhock Problems
- Rust: Rust is a common fungal disease that affects hollyhocks. It causes yellow or brown spots on the leaves. To prevent rust, water hollyhocks from below, avoid overhead watering, and keep the area around the plants clean and free of debris.
- Aphids: Aphids are small, green insects that feed on the sap of hollyhocks. They can cause leaves to curl and wilt. To control aphids, spray them with a strong stream of water or use an insecticidal soap.
- Japanese beetles: Japanese beetles are metallic green beetles that feed on the leaves and flowers of hollyhocks. To control Japanese beetles, handpick them off the plants or use a trap.
Tips for Growing Hollyhocks
- Choose the right variety: There are many different varieties of hollyhocks available, so be sure to choose one that is suited to your climate and garden conditions.
- Plant in groups: Hollyhocks look best when planted in groups of three or more.
- Provide support: Hollyhocks can grow to be quite tall, so it is important to provide them with support. You can use stakes, cages, or trellises.
- Overwintering: Hollyhocks are hardy in USDA zones 4-9. In colder climates, mulch around the plants in the fall to protect them from the cold.
Conclusion
Growing hollyhocks is a rewarding experience. With a little care, you can enjoy these beautiful flowers in your garden for years to come.
