March gardening jobs mark the true launch of the growing season in the UK.
Day length stretches to 11 to 13 hours, average temperatures range from 5 to 10 degrees Celsius, while frost risk drops but remains possible and rainfall averages 70 to 90 millimetres.
For gardeners, this month is about preparation, planting and protection. The tasks you complete now shape your harvest all year, so this guide divides jobs by week so you can match them to weather and soil conditions.
Week 1 – Soil and Structure
Test pH again if January results were borderline. Use a Soil Testing Kit and aim for 6.5 to 7.0. If acidic, spread ground limestone now so rain will carry it in before planting begins.
Fork over veg beds lightly on dry days and avoid walking on wet soil. Incorporate Compost Plus at 5 to 7 centimetres depth to feed microbes and mulch bare areas with Coir Mulch Mats to hold warmth and stop weeds. Inspect fences and sheds and apply Lifetime Wood Treatment to any bare wood – one coat lasts decades.
Week 2 – Early Planting
Sow broad beans and early peas direct if soil is 7 degrees Celsius or warmer. Use cloches if nights are cold. Plant bare-root fruit trees, roses and native hedging. Last safe window before growth restarts. Enrich holes with Peat-Free Compost. Sow hardy annuals such as calendula and cornflower under cloches or in trays. Divide overcrowded perennials like hostas. Plant native hedging to boost pollinators.
Week 3 – Greenhouse and Windowsill
Sow tomatoes, peppers and chillies in Coir Pots at 18 to 21 degrees Celsius. Sow onions from seed for exhibition size and prune roses and clematis group 3 before sap rises fully. Feed birds with Natural Suet Feeders to support nesting.
Week 4 – March Main Sowing and Protection
Sow carrots, parsnips and beetroot under fleece if soil is dry enough. Plant onion sets and shallots and apply Organic Neem Oil to emerging sprouts for pest defence. Sow Wildflower Seed Mix in trays for summer meadows. Also, check for slug damage and use natural barriers or nematodes.
March jobs set the foundation for your best season yet. A little work now means abundant harvests and fewer headaches later.
