The vegetable garden in May: plant pairings that attract pollinators

Buzz, it's Buzette! 🐝
May is the month when everything explodes in the garden. Frosty nights are over, the soil is warm, and insects are emerging en masse. If you want a bountiful vegetable garden this summer, now is the time to act – and the key isn't fertilizer or watering. It's pollinators.
A tomato not visited by a bee? No tomato. A zucchini ignored by a bumblebee? A zucchini that aborts. Up to 75% of the plants in your vegetable garden depend on pollinators to produce fruit.
Good news: there are magical plant combinations that attract bees, bumblebees, hoverflies, and butterflies directly to your home. Let's take a tour. 🌻
Why combine plants?
Before diving into the recipes, a quick word on companion planting. This is the art of planting together plants that mutually benefit each other:
- Some flowers attract pollinators to your vegetables
- Others deter pests (aphids, flea beetles, Colorado potato beetles)
- Still others enrich the soil or provide shade for more fragile plants
It's a win-win system. And most importantly, it's what transforms a "producing" vegetable garden into a living mini-ecosystem.
The star combination: Tomatoes + Basil + Marigolds
If you only remember one combination, this is it.
The winning trio:
- Tomatoes: your main crop, greedy for pollinators
- Basil: its white flowers attract bees, and its scent repels whiteflies
- Marigolds (Tagetes): their roots repel soil nematodes, and their bright orange flowers are adored by hoverflies (those small bee-mimicking flies that devour aphids)
How to plant? At the base of each tomato plant, place 2 or 3 basil plants and 1 marigold. Spacing: 30-40 cm between tomato plants, the rest fits around them.
Result: more fragrant tomatoes, fewer pests, and a continuous ballet of pollinators.
For zucchini, cucumbers, squash: bet on borage
Cucurbits (zucchini, squash, cucumbers, melons) are the most pollinator-dependent of all garden plants. A female zucchini flower is only fertile for a few hours. If no bumblebee passes by, the zucchini rots before it grows.
The magic solution: borage.
This plant with bright blue flowers is a magnet for bumblebees and bees. Plant a few plants between your rows of zucchini: pollinators will come for the borage and stay for your zucchini.
Bonus: borage flowers are edible (oyster-like taste, perfect in salads), and the plant self-seeds every year.
The universal ally: phacelia
If I had to offer only one flower to all gardeners in France, it would be this one. Phacelia (Phacelia tanacetifolia).
Why?
- It flowers in 6 to 8 weeks after sowing
- Its purple flowers are visited by over 100 species of pollinators
- It improves soil structure
- It self-seeds
- It is visually stunning
When to sow? Now, in May. Broadcast it in a corner of the vegetable garden or along an edge. You'll have a spectacular bloom from June to August.
For strawberries and small fruits: carnations and nasturtiums
Your strawberry plants need to be visited by bees to produce well-formed fruits. A poorly pollinated strawberry yields... a deformed strawberry.
The winning combo:
- Nasturtiums: their orange and yellow flowers attract bumblebees, and they serve as a trap crop for aphids (who prefer them to strawberry plants)
- Sweet William carnations: their sweet scent attracts butterflies and solitary bees
- Flowering chives: their purple pom-poms are irresistible to bees, and they deter aphids
Plant all of these along the border of your strawberry patch. You'll transform a utilitarian area into a super-productive flowering rock garden.
Flowers to absolutely sow in May
If your vegetable garden lacks flowers, it's still not too late. Here are my top 5 must-sows this month:
Cosmos Easy, fast-growing, tall (up to 1.20 m). Perfect at the back of a bed. Flowers from July to October. Adored by bumblebees.
Marigold (calendula) The Swiss Army knife of the vegetable garden. It attracts pollinators, repels nematodes, and its petals are edible. Essential.
Dwarf sunflower Dwarf varieties (60-80 cm) fit everywhere. A single flower can host up to 50 bees at once. A guaranteed spectacle.
Lavender Plant in May (as plants, not seeds). Pollinators go wild all summer, and it looks magnificent as a border.
Buckwheat Underrated but formidable. Ultra-fast growth, very nectar-rich white flowers, and it enriches the soil. Ideal for filling an empty corner.
Mistakes to avoid
Planting everything in straight lines A military-style vegetable garden is pretty but not very attractive to pollinators. Mix, scatter, create islands of flowers among the vegetables.
Forgetting simple flowers Double flowers (very full old roses, some dahlias) are inaccessible to bees: too many petals, no accessible pollen. Prefer simple flowers with visible stamens.
Mowing all the "weeds" Dandelions, clover, daisies are among the best melliferous plants in spring. Leave a corner of the lawn unmowed until the end of May. Pollinators will thank you.
Using insecticides, even "natural" ones Nettle manure sprayed directly can kill bees. Any treatment, even organic, should be done in the evening, never on open flowers.
And Asian hornets in all this?
An important side note: a vegetable garden that attracts bees also, unfortunately, attracts their predators. The Asian hornet hunts bees in hovering flight in front of hives and flower beds.
This is exactly why May is the key month for spring trapping. Capturing a queen now protects your garden's pollinators for the entire season.
If you've planted your nectar-rich plants, it's also time to set a selective trap nearby (but not in the bed itself) to intercept hornets without disturbing bees.
In summary: Buzette's checklist ✅
- ☐ Plant at least 3 different flowers in the vegetable garden
- ☐ Combine tomatoes + basil + marigolds
- ☐ Slip borage among the zucchini
- ☐ Sow phacelia in a corner
- ☐ Leave a patch of lawn unmowed
- ☐ Border strawberry beds with nasturtiums and chives
- ☐ No treatments, even organic, on open flowers
- ☐ Hornet trap installed away from flower beds
There you have it, everything you need to transform your vegetable garden into a pollinator paradise. And the beauty of it is, the more you welcome bees, the more your garden produces. That's the magic of living gardening. 🌱
