To grow Roman chamomile from seed, it is best to start in mid-spring when the soil is warm. This will provide the ideal conditions for germination and growth.
First, prepare the soil by removing any weeds or debris and loosening it with a garden fork or tiller. Chamomile prefers well-draining soil, so if your soil is heavy or clay-like, consider adding organic matter such as compost or well-rotted manure to improve its structure.
Once the soil is prepared, sow the chamomile seeds on the surface. Unlike some other seeds, chamomile seeds require light to germinate, so it is important not to bury them too deep. You can sprinkle the seeds evenly over the soil or sow them in rows, depending on your preference.
After sowing the seeds, it is crucial to protect them from slugs and snails, as these pests can quickly devour young seedlings. You can use various methods to deter these pests, such as placing copper tape around the planting area or using organic slug pellets. Regularly check for any signs of damage and take action if necessary.
Watering is essential to ensure the seeds germinate and the seedlings establish well. Keep the soil consistently moist but not waterlogged. Avoid overwatering, as this can lead to root rot. Use a gentle spray or watering can to water the seeds and seedlings, ensuring the water reaches the soil without disturbing the seeds.
As the seedlings grow, thin them out if necessary. This means removing some of the excess seedlings to give the remaining ones enough space to develop. Thin them to a spacing of 15-30cm (6-12in) apart, depending on how large you want the chamomile plants to grow. Thinning allows the remaining seedlings to receive adequate sunlight, nutrients, and airflow, promoting healthy growth.
During the growing season, chamomile plants benefit from regular watering, especially during dry spells. However, be mindful not to overwater, as chamomile prefers slightly drier conditions compared to other plants. Aim for a balance, keeping the soil moist but not saturated.
In terms of care, chamomile is generally low-maintenance. However, it is essential to monitor for any signs of pests or diseases and take appropriate action if necessary. Aphids and powdery mildew can occasionally affect chamomile plants, so keep an eye out for any symptoms and treat accordingly.
Harvesting chamomile can typically begin when the plants reach maturity, usually around 8-10 weeks after sowing. Harvest the flowers by gently picking them off the plant, being careful not to damage the stems or leaves. You can either use the flowers fresh or dry them for later use in teas, infusions, or skincare products.
Growing Roman chamomile from seed requires attention to soil preparation, proper watering, and protection from pests. With these considerations in mind, you can enjoy the beauty and benefits of chamomile in your garden or landscape.
