Planting and Care Tips
Proper planting and ongoing care are vital for thriving heirloom flowers in Zone 1. Follow these guidelines for the best results.
Timing Your Planting
Plant after the danger of the last frost has passed, typically late spring. Use soil temperature as a guide—wait until it reaches at least 50°F (10°C).
Soil Preparation
Heirloom flowers prefer well-drained, fertile soil. Amend your garden bed with compost or organic matter to improve soil structure and nutrients.
Protection and Mulching
Use mulch to insulate roots and retain soil moisture. Consider using straw, wood chips, or leaves. Cover plants with row covers or cold frames during unexpected frosts.
