Description

The Yellow Lupine is a specialist for acidic, light sandy soils and drives its strong taproot deep into the substrate. Through its nitrogen-fixing actinobacteria it fixes large amounts of atmospheric nitrogen and also captures otherwise unavailable phosphate with its roots. Its yellow, fragrant flower spikes are also a valuable forage for bees.

Care instructions

Sow the Yellow Lupine from April to June (weeks 14 to 26) on acidic to neutral, low-calcium soils, it does not thrive on calcareous soils. Plant the seeds about three centimeters deep. Cut back or mow the stand at flowering (July, week 28) and work it in flat before the stems harden.

Companion planting

Good neighbors

cabbage family (Brassicaceae)

particularly well established

Leguminous plants collect nitrogen in the soil, from which Brassicaceae benefit as heavy feeders.

carrot family (Apiaceae)

Peas and beans provide carrot and celery with nitrogen and grow as shallow-rooted plants without competition next to each other.

gourd family (Cucurbitaceae)

Beans and peas enrich the soil with nitrogen, which cucurbits, as heavy feeders, can make good use of.

Rather not

amaryllis family (Amaryllidaceae)

particularly well established

Allium species inhibit the nitrogen‑fixing rhizobia of legumes through their root exudates, which slows their growth.
