When to plant Lupins in Brighton

Plant into prepared soil around 24th February - 10th April, setting the crown at the same level it was growing before. Water in thoroughly straight away, then keep the soil just moist while the roots settle.

From 24th February, water newly planted lupins during dry spells in their first season. Aim for a deep soak rather than frequent light watering, and avoid leaving the soil sodden.

Remove faded flower spikes from 25th May to keep the display going and stop the plant putting energy into seed. If you leave some spikes to ripen, collect seed from the most reliable plants only.

After the main flowering flush, cut the flowered stems down to the basal growth from 9th July. Leave the new leafy shoots at the base, because that keeps the plant strong for next year.

From 28th October, remove any dead foliage and clear away fallen debris around the crown. Leave the crown intact and do not cut hard into the base, as established plants need that growing point protected.
