What to do in the garden in January
January in the UK garden is all about preparation. The days are slowly getting longer, but this is often the coldest and windiest month of the year, with frost and the odd fall of snow still likely. It may feel quiet outside, yet there is plenty you can do now to set your garden up for a strong start in spring.
Use the slower pace of mid winter to organise your shed or greenhouse. Tidy tools, clean pots and sort seed trays so everything is ready for the busy sowing season ahead. A few hours spent planning now will save time when growth begins in earnest.
Test and improve your soil
January is the perfect time to understand your soil before the growing season begins. A simple soil test kit will quickly tell you the pH of your soil, helping you decide what to plant and whether you need to adjust conditions.
If your soil needs improving, add organic matter or specialist composts to enhance structure and drainage. Healthy soil is the foundation of strong roots, better nutrient uptake and improved plant performance throughout the year.
Whether you are new to gardening or have years of experience, January is the month to reset, plan and prepare. Below are practical jobs to keep your ornamental and vegetable gardens on track.
