8 Garden Plants You Can Multiply For Free To Fill Your Borders Easily

Salvias are drought-tolerant perennials prized for their vibrant blooms and architectural foliage. Propagating them allows gardeners to expand their borders with minimal cost.

How to propagate salvias

1. Select healthy shoots: Choose non-flowering stems with fresh growth. Cut 10cm sections from the base of the plant.
2. Prepare the cutting: Remove lower leaves to prevent rot. Dip the cut end in rooting powder for better success.
3. Plant the cutting: Place in a pot with moist, gritty compost. Keep in a warm, bright spot away from direct sunlight.
4. Maintain conditions: Ensure consistent moisture and warmth. Roots should develop within weeks, ready for transplanting.

Common challenges and solutions

• Rooting failure: Use clean tools and fresh compost to minimize infection risks.
• Pests: Inspect cuttings regularly and treat with neem oil if necessary.
