Late May is one of the most important moments in the gardening calendar — and if you miss it, you'll be waiting another whole year. The good news? A handful of vegetables planted right now will reward you with an abundant harvest by midsummer. Here's exactly what to put in the ground before the window closes.
1. Tomatoes
Tomatoes are the undisputed star of the summer garden, and for good reason. Planted by the end of May, they'll be producing juicy, flavour-packed fruit right through the heart of summer. Give them a sunny spot and soil enriched with compost, and they'll thrive with very little fuss.
Key tip: tomatoes love warmth and good drainage — avoid heavy, waterlogged soil at all costs.
2. Peppers
Peppers are another late-May favourite. They need a warm, sheltered, sunny position to develop their full sweetness and depth of flavour. Well-draining soil and consistent watering are all they ask for in return — and they'll grow surprisingly fast once the heat kicks in.
3. Cucumbers
Cucumbers are cold-sensitive, which is exactly why late May is the ideal time to plant them — the soil is warm enough for them to establish quickly. They're typically grown as climbing plants, so give them a trellis or support structure to work with. Using a layer of mulch around the base helps retain soil warmth and moisture, which cucumbers absolutely love.
4. Beetroot
Beetroot is one of the most forgiving and resilient root vegetables you can grow. Plant it through May and it asks for very little: regular watering and steady nutrients. In return, you get vibrant, vitamin-rich roots that work beautifully in salads, roasted as a side dish, or blended into soups.
5. Green beans
Green beans are warm-weather growers at heart — they truly hit their stride in the hotter months. Sow them by late May and you can expect a generous crop by late summer. They need a sunny spot and, for climbing varieties, a simple stake or support to grow upward. Few vegetables are this easy and this rewarding.
6. Cabbage
Cabbage takes longer to mature than most of the vegetables on this list, but that's exactly why timing matters. Plant it by the end of May and you'll be harvesting firm, full heads just as the cooler autumn days arrive — which is when cabbage tastes its best. Keep an eye on watering and watch out for pests, as cabbage does attract a few unwanted visitors.
7. Carrots
Carrots are a quiet achiever in the spring and summer garden. Sown by late May, they mature at just the right time — and they couldn't be simpler to grow. The one thing they need is loose, sandy soil that lets their roots develop freely without obstruction. Compact or stony soil leads to forked, stunted carrots, so it's worth preparing the bed well before sowing.
Whether you have a large garden or just a few raised beds, these seven vegetables are worth making room for. Plant them now, care for them consistently, and by the time summer is in full swing, your garden will be producing more than you might expect. There's something genuinely satisfying about eating food you've grown yourself — and it all starts with getting the timing right.
