Each season brings different jobs. The seasonal guides tell you exactly what to sow, when to vent, and how to protect your plants as the weather shifts.

Most gardening content is written for a US or Mediterranean audience — different climates, different suppliers, different growing conditions. That creates real problems for UK gardeners trying to follow advice that simply does not apply here.
Every guide here is written with UK weather, UK suppliers, and UK growing conditions in mind. When we reference a variety or method, we are talking about what you can actually grow in British conditions and what works through our unpredictable seasons.
