Lupine: Direct Sow Perennial
How to Sow
Sowing Directly in the Garden:
- Direct sow in spring after danger of frost in a sunny location with well-drained, moist, slightly acidic soil. Sow where plants are to remain as they do not transplant well.
- Remove weeds and work organic matter into the top 6-8 inches of soil; then level and smooth.
- Sow seeds ¼ inch deep.
- Firm lightly and keep evenly moist.
- Seedlings will emerge in 14-28 days depending on soil and weather conditions.
- Thin to 18 inches apart.
How to Grow
- Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their germination.
- Mulches also help retain soil moisture and maintain even soil temperatures. For perennials, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
- Water thoroughly at least once a week to help new roots grow down deeply. Soil should be damp at about 1 inch below the soil surface. You can check this by sticking your finger in the soil. Water early in the morning to give all leaves enough time to dry. One inch of rain or watering per week is recommended for most perennial plants. You can check to see if you need to add water by using a rain gauge.
- Taller varieties may require staking.
- Plants bloom in summer, but if you cut the spent slower stalks back after blooming, the plants may reward you with a second flush of bloom in late summer or fall.
- Lupines are cool season plants that are at their best in areas with cool summer nights.
- These spiky plants are dramatic at the back of the border and beautiful for cut flowers.
- They naturalize well in wildflower meadows.
- The flowers attract hummingbirds and beneficial insects.
