Establishing a Chamomile Ground Cover

Suitable Chamomile Varieties

Different species and cultivars offer varying characteristics for ground cover applications. Common options include:

Chamaemelum nobile (Roman Chamomile): Known for its apple-like scent when crushed. Tolerates light foot traffic.
Chamaemelum nobile 'Treneague': A non-flowering cultivar that forms a dense, low-growing mat. Requires less mowing.
Matricaria chamomilla (German Chamomile): A self-seeding annual with stronger medicinal properties and more upright growth. Less suitable for a dense, walkable surface.

Considerations include flower production, growth habit, scent, and tolerance to foot traffic when selecting a variety.

Proper preparation is essential for successful establishment. Chamomile thrives in well-drained soil and requires full sun to partial shade.

Soil Testing: Determine soil pH and nutrient levels. Aim for a slightly acidic to neutral pH (6.0-7.0).
Weed Removal: Eliminate all existing weeds, including roots. Consider using herbicides or manual removal.
Soil Amendment: Incorporate organic matter, such as compost, to improve drainage and fertility.
Leveling: Ensure a smooth and level surface for uniform growth.

Chamomile can be propagated from seed or through the use of plugs (small, pre-grown plants).

From Seed: Seeds can be directly sown in spring or early fall. Scatter seeds evenly over prepared soil and lightly rake in. Keep the soil consistently moist until germination. Germination can be slow and uneven.
From Plugs: Planting plugs provides a more reliable and faster establishment. Space plugs 6-12 inches apart, depending on the desired density.

Specific techniques vary depending on the chosen propagation method.

Seed Sowing: Lightly compress the soil after sowing seeds. Water gently to avoid disturbing the seeds. Monitor for weed growth.
Plug Planting: Dig holes slightly larger than the plug size. Carefully remove the plugs from their containers and plant them at the same depth as they were growing. Water thoroughly after planting.

Ongoing maintenance is crucial for a healthy and attractive ground cover.

Watering: Water regularly, especially during dry periods, until plants are well-established. Once established, chamomile is relatively drought-tolerant.
Weeding: Remove weeds promptly to prevent competition. Hand-pulling is generally the best option.
Mowing: Mow occasionally to maintain a desired height and encourage denser growth. Avoid mowing too short.
Fertilizing: Apply a balanced fertilizer in spring if needed, based on soil test results. Avoid over-fertilizing.
Foot Traffic: Limit heavy or concentrated foot traffic, especially during establishment.
