Pruning
To maintain the plant's shape and promote healthy growth, pruning should occur during the dormant season. Cut back the oldest stems at ground level and clip back the newer stems to roughly one-third of their length. This practice encourages new growth and helps prevent the center of the plant from becoming too dense.
Propagation of Spiraea lucida Dougl. ex Greene
Spiraea lucida Dougl. ex Greene, also known as shiny-leaved meadowsweet, is a beautiful shrub that produces clusters of pink flowers in summer. The plant is native to western North America and can be propagated through various methods:
Seed propagation
The most common way to propagate Spiraea lucida is through seeds. Collect the seeds from the plant during autumn and sow them in well-drained soil in a greenhouse or seedbed. The seeds usually take 2-3 months to germinate, and once they have reached a height of 5-10cm, they can be transplanted into individual pots.
Cutting propagation
Propagation of Spiraea lucida can also be done through cuttings. Take a 10cm cutting from the plant's semi-hardwood stem in the summer, and remove any leaves from the lower end. Dip the cutting into rooting hormone powder and plant it in a pot filled with a mixture of peat and perlite. Keep the pot in a humid environment and water the cutting regularly until it has established roots.
Division propagation
You can also propagate Spiraea lucida through division during spring or fall. Dig out the plant and remove any dead or diseased roots. Divide the root ball into small sections, each with a few stems and roots, and plant them in well-drained soil. Give them enough water and sunlight, and in a few weeks, new shoots should start growing.
Propagation of Spiraea lucida is an easy and rewarding task that can help you fill your garden with these beautiful shrubs. Choose the method that suits you the best and start propagating today!
