What to plant in May
Seed sowing in the greenhouse has started to slow down, as now many crops can be sown direct into the soil outside. I repeat sowings of salads and roots, such as carrots and radish, to continue the supply, while sowing or planting out tender beans including borlotti, edamame and French.
Summer-loving crops, such as celeriac, tomatoes and sweet potatoes, leave the greenhouse and are planted into beds or containers.
I like to plant our squashes and pumpkins among sweetcorn, incorporating Amaranthus ‘Autumn Palette’, Persicaria orientalis, Tagetes ‘Cinnabar’ and Tropaeolum majus. By summer the patch is full of foliage and colour that gets better as harvest approaches.
If space is at a premium, try a tumbling tomato mixed with Tropaeolum minus ‘Ladybird Rose’ and Thai basil. All suited to container growing, they’ll look good all summer while providing something to taste.
In the borders, seed-grown antirrhinums, cosmos and scabious are planted to fill gaps, while containers hold nemesias, salvias and verbenas. For foliage fillers, I love to use scented pelargoniums such as ‘Pink Capricorn’ or the silvery Helichrysum microphyllum ‘Silver Mist’ and Plectranthus argentatus. Experimentation is key and this year I’m including the cascading Dichondra ‘Silver Falls’, with floriferous perennials such as Verbena ‘Bampton’.
