Horehound can be established from seeds and harvest the first year. The leaves have a wooly crinkled appearance, and the small, off-white hairy flowers bloom in the summer.

Plant indoors 4 - 6 weeks before the last frost. Or, start directly outdoors after danger of frost has passed.

Plant in full sun with moist, well-drained soil.

• You have two options for planting seeds: Sow them directly into the garden at a depth of 1/4 inch after the risk of frost has passed. Alternatively, start seeds indoors four to six weeks before the average last frost date in spring.
• Presoak seeds overnight before planting 2 - 3 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 10 inches apart in garden.

• 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 seeds from germinating.
• 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.
• Water regularly, but do not overwater. Let soil dry out in between waterings.
• Cut back for new flushes of growth and extended harvests.
