Whether you’re maintaining a small garden, a large landscape, or commercial grounds, May is one of the most important months in the gardening calendar. With longer days, warmer temperatures, and rapid plant growth, it’s the perfect time to get your outdoor spaces thriving. But what are the important gardening tasks for May? And how can you make the most of this key growing period?
So, what are the important gardening tasks for May?
Staying on top of essential gardening jobs in May will help ensure your garden remains healthy, vibrant, and well-prepared for the summer months ahead. Key tasks to prioritise include:
- Lawn care and mowing
- Planting summer bedding plants
- Weeding and soil maintenance
- Pruning and training plants
- Watering and irrigation management
- Pest and disease control
- Supporting wildlife and pollinators
Lawn care and mowing
As temperatures rise, grass growth speeds up significantly. This means that regular mowing becomes essential in May to keep lawns neat, healthy, and under control. It’s important not to cut the grass too short, as this can stress the lawn and encourage weeds. Instead, aim for consistent trimming while maintaining a reasonable height.
May is also a great time to repair any bare patches and apply lawn feed to encourage thick, green growth.
Planting summer bedding plants
With the risk of frost largely behind us, May is ideal for planting summer bedding plants. Bright, colourful flowers such as petunias, marigolds, and geraniums can be introduced to beds, borders, and containers to create vibrant displays.
This is also the perfect time to plant hanging baskets and window boxes, helping to add colour and visual interest to your outdoor areas.
Weeding and soil maintenance
Weeds grow quickly during May, competing with your plants for nutrients, water, and sunlight. Regular weeding is essential to keep them under control and prevent them from spreading.
In addition to removing weeds, it’s important to improve soil quality. Adding compost or organic matter can boost nutrients and help retain moisture, giving your plants the best possible conditions to grow strong and healthy.
Pruning and training plants
May is a key time for pruning certain shrubs and training climbing plants. Spring-flowering shrubs can often be pruned after they finish blooming to encourage healthy growth for the following year.
Climbing plants such as clematis and roses should be tied in and supported as they grow, helping to maintain structure and prevent damage.
Watering and irrigation management
As the weather becomes warmer and drier, consistent watering becomes increasingly important. Newly planted flowers, young plants, and containers will need regular attention to prevent them from drying out.
Watering early in the morning or later in the evening helps reduce evaporation and ensures plants can absorb moisture effectively. Installing or maintaining irrigation systems can also make managing larger gardens or commercial spaces much more efficient.

What are the benefits of hiring a professional grounds and gardening team in May?
While May is an exciting and productive time in the garden, it can also be demanding, especially for larger spaces or commercial properties. Hiring a professional grounds and gardening team can make a significant difference in both the appearance and health of your outdoor areas.
