How to Plant Xeranthemum Annuum
- You have two options for planting seeds: Sow them directly into the garden at a depth of no more than 1/16 inch after the risk of frost has passed. Alternatively, start seeds indoors six to eight weeks before the average last frost date in spring.
- Presoak seeds overnight before planting 3 - 4 seeds per cell or plant.
- Once seedlings sprout, ensure they receive plenty of light by placing them on a sunny windowsill or positioning them 3-4 inches below fluorescent plant lights that are switched on for 16 hours daily and off for 8 hours at night. Adjust the lights as the plants grow taller. Avoid using incandescent bulbs as they generate excessive heat. Remember, most plants need a period of darkness to thrive, so do not keep the lights on for 24 hours.
- Transplant into garden when temperatures are consistently warm.
- Before transplanting seedlings into the garden, it's essential to "harden them off". This involves acclimating young plants to outdoor conditions by placing them in a sheltered outdoor area for about a week. Initially, shield them from strong winds and direct sunlight. If there's a risk of frost overnight, either cover the plants or bring them indoors, then return them outside in the morning. This hardening off method helps strengthen the plant's cell structure, minimizing transplant shock and sun damage.
- Space plants 15 - 18 inches apart in garden.
Care And Maintenance
- Maintain weed control throughout the growing season. Weeds can compete with plants for water, space, and nutrients, so it's essential to manage them by regular cultivation or by applying mulch to stop their seeds from sprouting.
- Mulches play a crucial role in retaining soil moisture and regulating soil temperatures consistently. When dealing with annual plants, using organic mulch made from shredded leaves can enhance the appearance of the bed naturally and enrich the soil as it decomposes over time. Remember to avoid placing mulch directly against a plant's stems to avoid potential rot issues.
- During its first year of establishment, give the young plants consistent moisture. After that, watering only once a week is best. However during the dry, hot summer months water two to three times a week. Make sure to keep the soil relatively moist but not wet.
- Cut off any yellowed, spotted or dying leaves to help keep the plant healthy and encourage further growth.
- To dry your Xeranthemum, cut flowers in the morning when the blooms are just beginning to open. Hang cut flowers in buches upside down in a warm, dark, well-ventilated room for 2 - 3 weeks, or until they are firm to the touch.
