Planting and Care Tips
- Soil Preparation: Add compost or aged manure to garden beds before planting to improve fertility and drainage.
- Moisture Management: Water thoroughly after transplanting, especially during dry spells. Mulch to retain soil moisture and suppress weeds.
- Spacing: Give each perennial room according to mature size to avoid overcrowding and ensure best air circulation.
- Deadheading: Remove spent flowers regularly to stimulate new blooms and keep plants tidy.
- Fertilization: Most perennials do well with a spring application of a balanced slow-release fertilizer. Avoid overfeeding, which leads to lush foliage but fewer flowers.
