"June, the month of Leaves and Roses"
What to sow in June.
Traditionally June is the month of roses when these lovely blooms are at their best. With the promise of sunnier days to come I keep sowing a variety of salad crops: beetroot, lettuce, spring onions, rocket and radishes. (Leafy salad crops may do better when sown in partially shady sites since hot dry weather can lead to bitter tasting leaves.) My outdoor tomatoes are hardened off and planted out in their tubs. It is generally safe to assume the last frost is over (but not guaranteed with our changeable weather).
I have direct sown runner beans under their frame and courgettes in a large tub. You could direct sow French beans both dwarf and climbing types, peas, pak choi, spinach, squash, sweetcorn, and outdoor cucumbers. Autumn crops of kale, calabrese, turnips and kohl rabi should be sown now as well..
Don’t forget your herbs (often expensive in the supermarket and can be grown repeatedly for just a few pence worth of seeds). These tasty plants add beauty and fragrance to the garden while attracting pollinators and beneficial insects. Certain herbs are better adapted to grow during the heat of summer than others. Amongst the best herbs to grow for summer are basil, chervil, coriander, dill, fenugreek, oregano, parsley, sage, savory, rosemary and thyme. Sow either in open ground or containers.
For flowers late summer I have sown nasturtiums, calendula (pot marigolds) and poached egg (Limnanthes douglasii). You might also sow candytuft, clarkia (godetia), larkspur, nigella and sunflowers too. Or thinking further ahead; winter flowering pansies and spring flowers for next year such as alstroemeria, aquilegia, erigeron, delphiniums and lupins.

It is the month of June, The month of leaves and roses, When pleasant sights salute the eyes, And pleasant scents the noses...
