Plant cloves straight into a prepared bed for the most reliable UK crop. They sit through winter and bulk up for harvest the following summer.

  1. 01

    Prepare the Bed

    28 Nov to 12 Dec

    Dig the bed over well around 28th November - 12th December, then work in garden compost or well-rotted manure. Make sure the soil drains freely, because cloves can rot if the bed stays wet in winter.

  2. 02

    Plant Cloves

    12 Dec to 28 Dec

    Plant the cloves during 12th December - 28th December, with the pointed end up and the cloves deep. Space them apart and water in thoroughly straight after planting.

  3. 03

    Keep Weed Free

    19 Jan to 18 Jun

    From 19th January onwards, keep the row clear of weeds so the bulbs are not robbed of light and moisture. Water only in dry spells, and mulch lightly if the soil is prone to drying out at the surface.

  4. 04

    Harvest Bulbs

    18 Jul to 22 Aug

    Lift the bulbs when the foliage starts to yellow and collapse, usually from 18th July to 22nd August. Ease them up carefully with a fork, then dry them in a warm, airy place for two to three weeks before storing.

Why companion planting matters

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
