Flowers to sow in June include, for outdoor sowings, alstroemeria, achillea, arabis, canterbury bells, coreopsis, erigeron, myosotis and sweet william seeds.
Sow in the greenhouse polyanthus, primrose and pansy for autumn planting to flower in spring.
June’s warmer weather also means that flowers to sow in June include the raising of foliage plants as houseplants. To brighten up winter and spring displays indoors, make sowings of calceolaria, cineraria and primula obconica.
Preparation of the ground for bedding plants can now be done, as well as thinning out plants that have already been sown. And now is the ideal time to prepare the greenhouse against hot days by either using shade netting or a shade paint.
