What to plant in May? Let’s delve into the world of fruits, flowers, and vegetables, and explore the fascinating rhythm of May gardening in the UK.
Garden Maintenance in May
While you’re in the process of deciding ‘what can I plant in May’, there are a few jobs that need doing in the garden.
Make sure your furniture is cobweb-free and clean, and you’ll have more garden waste so you’re going to need a big compost bin.
Before you start pruning your shrubs, walk around the garden and check for nesting birds, as well as making sure your weeding is under control. Remember to be on the lookout for pests and diseases.
What Vegetables to Plant in May
Choosing what seeds to plant in May could take you a while! There’s a whole host of amazing vegetables that can go in the ground this month and you can start with a global tour of beans.
Borlotti beans from Italy, edamame beans from Japan and French beans from – believe it or not – Central and South America, can all be sown outdoors in May.
Sweetcorn can be planted in seed trays and then transferred outdoors when the seedlings are big enough, and if you planted cucumber seeds in April, you can now get them into the ground.
Purple sprouting broccoli, carrots, red chicory, peppers, parsnips and salad leaves can all go straight into the ground.
Deciding what to plant in May in the greenhouse can be a time-consuming affair because there’s so much to choose from. Sow lettuce and rocket every three weeks or so for a harvest all through the summer and autumn. If you didn’t have the space last month, courgettes, squash and pumpkins can all be sown undercover.
Herbs like basil, thyme and lovage can also be sown undercover.
Sowing & Growing Fruit in May
Strawberries and gooseberries can be planted out now and once the fruit starts to swell and ripen, cover the plants with well-pegged nets to deter birds.
Like strawberries, raspberries can also be planted out at this time. If space is at a premium, they can also be planted in containers. Indeed, raspberries is one of the best answers to the question ‘what can I plant in May’ because they will regrow year after year!
What Flowers to Plant in May
