With milder weather and extended daylight hours, May marks the moment when gardens truly burst into life. All those months of grafting throughout winter finally begin to bear fruit. Plants start sprouting afresh, and outdoor spaces become ideal spots for entertaining and unwinding.
It is also a critical period for planting summer staples and monitoring plant wellbeing, according to specialists. The horticultural expert at Cherry Lane Garden Centres has outlined the "key" gardening tasks to tackle in May.
Plant Up Hanging Baskets
The experts said: "May is the perfect time to plant up hanging baskets with colourful summer favourites such as petunias, fuchsias and geraniums." Keep newly planted baskets in a sheltered spot for a short period to help them establish before placing them outside where they will enjoy plenty of sunshine.
Sow French and Climbing Beans
Rising soil temperatures this month make it an "ideal time" to sow French beans and climbing beans straight into the earth. The specialists advised selecting a sunny, protected location and making certain the soil is properly prepared and nourished to encourage robust growth.
Plant Your Bedding Now the Frosts Have Finished
The experts said: "With the risk of frost largely behind us, May is the time to plant out bedding plants." Varieties such as begonias, marigolds and petunias will quickly add colour to borders, pots and containers, helping gardens look vibrant heading into summer.
Check Plants for Pests and Diseases
As the weather warms up, summer nuisances like aphids and slugs become increasingly active in outdoor spaces. Be sure to inspect plants regularly for signs of damage or disease, and respond promptly when necessary. The professionals highlighted: "Removing affected leaves early or treating infestations promptly helps keep plants healthy."
Repot and Feed Houseplants
Indoor plants will be growing more vigorously in May, making it an ideal time to repot those that have outgrown their current containers. New compost and a gentle feed will supply the nutrients plants require to flourish during the warmer months ahead.
Add Plants to Garden Ponds to Help Wildlife
The gardening specialists explained: "Adding aquatic plants to ponds in May helps create a balanced ecosystem. Plants provide shelter for wildlife, improve water quality and help prevent excessive algae growth by absorbing nutrients."
Plant Out Dahlia and Canna Tubers
Dahlia and canna tubers can be introduced into the garden during May. Ensure you select a sunny location with well-draining soil. The specialists noted that these varieties will reward you with "bold, colourful blooms throughout the summer".
Add Interest with Ferns and Hostas
Shadier sections of the garden can still be brimming with vegetation, the professionals advised. This includes incorporating ferns and hostas, which thrive in dim light.
