Skimmia is a popular evergreen shrub valued for its fragrant flowers and attractive berries. Propagating skimmia allows gardeners to expand their garden or share plants with friends. This guide provides step-by-step techniques to successfully propagate skimmia.
Understanding Skimmia Propagation
Skimmia can be propagated through several methods, including cuttings, seed sowing, and division. Among these, taking cuttings is the most common and reliable way for gardeners to produce new plants that are true to the parent.
Propagating Skimmia by Cuttings
This method involves taking young, healthy cuttings from the parent plant and encouraging them to develop roots. It is best done in late summer or early autumn.
Materials Needed
- Sharp pruning shears or scissors
- Rooting hormone (optional but recommended)
- Small pots or containers
- Well-draining potting compost
- Plastic bag or propagator
- Watering can
Steps for Taking Cuttings
Follow these steps to take successful cuttings:
- Choose healthy, non-flowering shoots about 10-15cm long.
- Use sharp scissors or shears to cut just below a leaf node.
- Remove the lower leaves, leaving only a few at the top.
- Dip the cut end into rooting hormone to encourage root development.
- Plant the cutting into a pot filled with moist, well-draining compost.
- Cover the pot with a plastic bag or place it in a propagator to maintain humidity.
- Place the pot in a warm, bright location but out of direct sunlight.
- Keep the compost moist but not waterlogged.
- Wait several weeks for roots to develop, checking periodically.
Propagating Skimmia by Seeds
Growing skimmia from seed is possible but takes longer and has less predictable results. Seeds require stratification, a process of cold treatment, to break dormancy.
Seed Collection and Preparation
- Wait until berries turn red and are fully ripe.
- Collect berries and extract seeds carefully.
- Clean the seeds and soak them in water for 24 hours.
- Stratify the seeds by placing them in moist sand or compost in the refrigerator for 3-4 months.
Planting Seeds
After stratification:
- Plant seeds in pots filled with seed-starting compost.
- Cover lightly with compost or vermiculite.
- Maintain moist conditions and place in a warm, bright location.
- Germination can take several months, so patience is required.
Dividing Skimmia
Dividing mature skimmia plants is another propagation method, suitable for established shrubs. It involves separating a section of the root ball and replanting it.
Steps for Division
- Choose a mature, healthy skimmia shrub in early spring or late autumn.
- Dig around the base to expose the root system.
- Use a sharp spade or knife to divide the root ball into sections.
- Plant each division in a prepared hole with well-draining soil.
- Water thoroughly and mulch around the new plants.
Care Tips for Propagated Skimmia
Once propagated, skimmia plants require proper care to establish and thrive. Here are some essential tips:
- Plant in a sheltered, partially shaded location.
- Ensure the soil remains moist but not waterlogged.
- Apply mulch to conserve moisture and suppress weeds.
- Feed with a balanced, slow-release fertilizer in spring.
- Prune lightly after flowering to maintain shape.
Conclusion
Propagating skimmia is a rewarding process that allows gardeners to multiply their plants and enjoy their fragrant blooms year after year. Whether through cuttings, seeds, or division, patience and proper care will ensure successful propagation and healthy new plants.
