Care
Light Exposure
Place clustered clover in full sun to partial shade for good flowering. It tolerates sunny locations well and develops satisfactorily even with moderate light. Avoid completely shaded areas and overly damp spots.
Soil
This clover adapts to well-drained soils, even lean or poor ones. It prefers to avoid compacted and permanently waterlogged ground. Slightly acidic to neutral pH suits it well.
Watering
Water moderately, especially during active growth periods. Once established, it tolerates dry spells thanks to its deep root system. Let the soil dry slightly between waterings to prevent root rot.
Fertilizing
No fertilizer is necessary: as a legume, it fixes atmospheric nitrogen and enriches the soil. Excess nitrogen can reduce flowering and hardiness.
Pruning and maintenance
Little maintenance required. You can cut back faded stems after flowering to encourage branching. Leave some flowers in place if you want natural self-seeding.
Diseases and pests
Very few problems. Monitor excessive moisture which can promote rot. Wild clovers are generally robust and little affected by common garden pests.
Did you know?
Clustered clover is an excellent green manure: farmers once sowed it in fallow fields to naturally regenerate depleted soils. Its small pink to red flowers, tightly packed into compact balls, make it easily identifiable among other clovers, and it remains a valuable resource for pollinators and a subtle yet effective nectar plant.
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.
