How to grow Scabiosa Seeds
When to sow: In most regions, sow seeds outdoors in early spring after the last frost date. If starting seeds indoors, begin about 6 to 8 weeks before the last frost date to give the seedlings a head start.
Sowing: Prepare the planting area by loosening the soil to a depth of 15 to 20 centimeters and removing any debris. Sow the seeds thinly and evenly over the soil surface, then cover lightly with a thin layer of soil and press down gently to ensure good seed-to-soil contact. After sowing the seeds, water the area gently. Use a fine mist or gentle spray to avoid disturbing the seeds.
Spacing: If planting multiple rows of scabiosa, space them about 20-30cm apart to allow for adequate air circulation and future plant growth.
Germination and Thinning: Scabiosa seeds typically germinate within 7-14 days, depending on temperature and soil conditions. Keep the soil consistently moist but not waterlogged during the germination period. Once the seedlings have emerged and developed a few true leaves, thin them to the desired spacing, leaving the strongest and healthiest plants.
Transplanting (Optional): If you started scabiosa seeds indoors, transplant the seedlings into the garden after the danger of frost has passed and the seedlings have developed several sets of true leaves. Be sure to harden off the seedlings gradually before transplanting to acclimate them to outdoor conditions.
Support and Deadheading: Tall scabiosa flowers may benefit from staking or support to prevent them from bending or flopping over. Additionally, deadhead spent flowers regularly to prolong the blooming period and encourage the plants to produce more flowers.
