Expert tips
The key tip
This very hardy perennial daisy loves dry, well-drained soil. Once established (after the first summer), it needs very little watering.
The common mistake
Watering too regularly in winter: it rots slowly if the soil stays wet.
The pro's trick
Divide the clumps every 3 years in spring to rejuvenate the plant and multiply your flowering stations.
Care
Exposure
Caucasian chamomile prefers full sun for optimal growth and abundant flowering. It tolerates well-exposed, breezy locations. Sunny exposure for at least 6 hours per day ensures healthy vigor.
Watering
Water regularly during the growing and flowering period, keeping the soil moist but well-drained. Reduce watering in winter. Avoid excess water, which promotes rotting and fungal diseases.
Soil
This plant adapts well to most ordinary soils, provided they are well-drained. Light, slightly chalky or neutral soil is ideal. Improve heavy soils with compost or sand.
Fertilizing
A balanced fertilizer application in spring is usually sufficient. For prolonged flowering, you can apply diluted fertilizer every 4 to 6 weeks during the flowering period. Avoid excess nitrogen, which promotes foliage at the expense of flowers.
Pruning and cutting
Pinch young plants to encourage more compact growth and better branching. Regularly remove spent flowers to extend the flowering period. Light pruning in late summer can encourage a second flush of blooms.
Diseases and pests
This chamomile is generally robust and not very prone to disease. However, watch for powdery mildew in humid conditions and aphids in spring. Good drainage and ventilation prevent most fungal problems.
Did you know?
The genus Tripleurospermum, to which Caucasian chamomile belongs, is distinguished from common chamomiles (Matricaria) by its unique flower structure: its disk flowers lack fertile achenes, making it less prone to self-seeding. This botanical peculiarity makes it interesting for gardens where you want to control chamomile spreading.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
