Care
Light exposure
Intermediate clover thrives in full sun or partial shade. It prefers bright locations for generous flowering and good vitality. A sunny exposure also promotes its robustness and resistance.
Soil
Plant it in well-drained, neutral to slightly acidic soil. Clover adapts to poor and even chalky soils, making it a very tolerant plant. Avoid constantly waterlogged soils that promote rot.
Watering
Once established, intermediate clover requires little watering. Water regularly for the first few weeks after planting, then gradually reduce. It tolerates summer drought well and natural rainfall is usually sufficient.
Pruning and cutting
Prune lightly after main flowering to stimulate renewal and prevent an overly invasive habit. You can also cut back hard in spring to rejuvenate clumps. This action promotes more compact branching.
Fertilizer
No fertilizer is necessary. As a legume, clover fixes atmospheric nitrogen in the soil through root nodules, making it a self-sufficient plant and beneficial for the fertility of surrounding soil.
Diseases and pests
Intermediate clover is very resistant to diseases. Watch for excess moisture that may promote fungi. Under normal drainage and aeration conditions, phytosanitary problems remain rare and minor.
Did you know?
Intermediate clover, like all clovers, maintains a remarkable symbiotic relationship with bacteria of the genus Rhizobium that live in its roots and convert atmospheric nitrogen into assimilable nutrients. Historically, this natural fertilizing power made clover a valuable rotation crop in agroecology, allowing farmers to restore soil fertility without chemical inputs.
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.
