How to Propagate Hollyhocks from Cuttings

by

Hollyhocks are beautiful, tall flowering plants that add charm and color to any garden. Propagating hollyhocks from cuttings is an effective way to produce new plants that are true to the parent. This guide will walk you through the process step by step.

Choosing the Right Time and Materials

The best time to take hollyhock cuttings is in late spring or early summer when the plant is actively growing. You will need sharp pruning shears, rooting hormone (optional but recommended), pots or trays, well-draining potting soil, and plastic bags or a propagator.

Preparing the Cuttings

Choose healthy, non-flowering stems that are about 4 to 6 inches long. Cut just below a leaf node using sharp scissors or pruning shears. Remove the lower leaves to expose the node, leaving only a few leaves at the top.

Applying Rooting Hormone and Planting

Dip the cut end of the stem into rooting hormone to encourage root development. Insert the cuttings into pots filled with moist, well-draining soil, burying at least one node. Gently firm the soil around the stem to secure it in place.

Creating a Humid Environment

Cover the pots with plastic bags or place them in a propagator to maintain high humidity. Ensure the plastic does not touch the leaves and that there is some ventilation to prevent mold. Keep the soil moist but not waterlogged.

Providing Proper Care and Monitoring

Place the cuttings in a warm, bright location with indirect sunlight. Check regularly for signs of root growth, which typically occurs in 4 to 6 weeks. Keep the soil moist and remove the plastic cover gradually to acclimate the new plants.

Transplanting the Rooted Cuttings

Once the cuttings have developed a strong root system, transplant them into larger pots or directly into your garden. Choose a sunny spot with well-draining soil. Water thoroughly and continue to care for your hollyhocks as they grow.

Tips for Successful Propagation

  • Use sharp, clean tools to prevent disease.
  • Maintain consistent moisture without overwatering.
  • Provide plenty of light but avoid direct, harsh sunlight initially.
  • Be patient; roots may take several weeks to develop.

With proper care and patience, you can successfully propagate hollyhocks from cuttings and enjoy their vibrant blooms year after year.
