Flowers to Plant
Late spring bulbs are fading, now is the perfect time to plant colourful flowers that will carry your garden through summer.

Your kitchen garden is calling! May is a great time to sow and plant out a range of vegetables, either in open ground or containers.
Vegetables to plant in May:
- Sow beetroot, carrots, salad leaves, and radishes
- Plant out courgettes, runner beans, and climbing plants
- Support young seedlings with canes or trellis
Tip: Harden off any plants raised in a greenhouse before planting outdoors. This reduces shock from sudden temperature changes. The month of May offers a final chance to get early veg started—perfect for your summer harvest.
Water, Weed & Mulch
As the weather warms, keeping your garden hydrated is essential.
- Water regularly, especially pots, seedlings, and new plantings
- Add a layer of mulch around perennials to retain moisture and suppress weeds
- Stay ahead of weeds—they grow fast in warmer soil
Dry spells can stress flowers and vegetables, so deep, consistent watering ensures better yields and extended bloom times.
Pest and Disease Watch
With growth comes challenges. Be alert for common pests and diseases:
- Aphids on roses and beans
- Slugs and snails attacking seedlings and perennials
- Powdery mildew on vulnerable foliage
Use organic controls where possible, and invite garden birds and beneficial insects to your space. A healthy, balanced garden ecosystem helps keep pests in check.
Lawn Care and Garden Maintenance
Now is a great time to focus on your lawn and general garden maintenance:
- Mow weekly, but avoid cutting too short
- Reseed bare patches and feed with a nitrogen-rich fertiliser
- Edge borders for a neat finish
If moss or weeds are an issue, scarify the lawn and apply treatments early. Good lawn care now creates a lush space to enjoy your garden all summer long.
Prune, Tidy, and Prepare
Pruning and tidying helps plants focus energy on strong, productive growth.
- Prune shrubs that flowered in early spring
- Divide clumps of perennials for better air circulation and more blooms
- Tidy up borders and remove any frost-damaged or leggy growth
This is also a good time to assess your hedges and give them their first gentle trim of the year. If you are unsure, your garden centre will help with expert advice and healthy young plants. It is also a great source of inspiration, especially when tackling new garden jobs.
