Jobs for May
May is one of the most exciting months in the gardening calendar. With longer days, warmer temperatures, and the risk of frost fading, gardens really begin to burst into life. It’s the perfect time to get stuck in and set the foundations for a colourful, productive summer ahead.
Planting & Sowing.
May is prime planting season. Sow hardy annuals directly into borders for easy colour later in the summer. You can also begin planting out tender plants such as tomatoes, courgettes, and beans—but keep an eye on late frosts and be ready to protect them if needed. Bedding plants can go out towards the end of the month once the weather settles.
Lawn Care
Lawns will be growing strongly now, so regular mowing is essential—aim to cut little and often. This is also a good time to feed your lawn with a spring/summer fertiliser to keep it lush and green. If you notice bare patches, reseed them now while conditions are ideal.
Borders & Beds
Keep on top of weeds while they’re still small—it’ll save you time later. Mulching beds with compost or bark will help retain moisture and suppress weeds. Support taller plants like delphiniums and peonies before they flop, and pinch out tips of certain plants to encourage bushier growth.
Fruit & Veg
Vegetable plots need plenty of attention this month. Earth up potatoes, sow carrots, beetroot, and salad crops little and often for a continuous harvest. Strawberry plants should be protected from birds—netting is your best friend here!
Greenhouse & Pots
Watering becomes more important as temperatures rise. Check pots and containers daily, especially in sunny weather. Feed plants regularly to encourage strong growth and flowering. Open greenhouse vents on warm days to prevent overheating.
Wildlife & General Care
Encourage pollinators by planting nectar-rich flowers (Lavender, Buddleja, Echiums, Marjoram, and Sedums), and avoiding harsh chemicals. Top up bird feeders and keep water sources clean. It’s also a great time to tidy up edges, pathways, and outdoor spaces ready for enjoying your garden.
Final Tips
May is a month of growth and opportunity. Stay flexible with the weather, keep an eye on overnight temperatures, and enjoy the process—your garden will reward you in the weeks ahead.
Whether you’re growing your own vegetables, creating a colourful display, or simply keeping things tidy, a little effort in May goes a long way toward a beautiful summer garden.
