United Kingdom & Ireland

Allotment timing, month by month.

A UK or Irish plot runs on a different clock from the USDA map most growing advice is written for: mild, wet winters, a long cool spring, and slugs. agripure reads its plant database through RHS hardiness ratings for these islands, and its allotment guides run month by month.

The guides below were written for UK plots — allotments, no-dig beds, peat-free compost, pigeons and slugs, and fruit trees for small gardens. The plant database adds the species rated fully hardy through a British winter.

Plant profiles carry an RHS hardiness rating (H1a tender to H7 hardiest) alongside the USDA range; filter the plant finder by rating.
