Sowing and Growing:

  • Plant out your greenhouse-grown plants, ensuring they're well established and hardened off. Use straw or newspaper as ground cover for protection from late frosts.
  • Thin out hardy annuals, giving them around 30cm of space to promote better growth. Plants like cornflowers, nigella, and cosmos thrive with more room.
  • Directly sow biennials like wallflowers, forget-me-nots, and foxgloves for establishment before winter.
  • Fill gaps in borders with bedding plants such as Salvia. Water them regularly, especially in dry weather.
  • Directly sow poppies, which will flower within 8 weeks. Avoid transplanting to minimize root disturbance.
  • Deadhead spent flowers to encourage a second bloom. This is especially effective with annuals for seed production.
  • Pull out spring bulbs or divide clumps like snowdrops and daffodils.
  • Stake dahlias and other heavy blooms as they grow.
  • Enjoy picking lilies, alliums, sweet peas, peonies, and more from your garden in June.

Perennials Pruning & Tidying

Here are some tips to keep your garden in shape and promote healthy growth:

  • Keep weeding and deadheading for a beautiful border. Use mulch on moist soil if not done in spring. Handle aphids with soap-based water if necessary.
  • Prevent wind damage by staking and tying taller perennials. Metal supports and flower rings work well for vulnerable plants like delphiniums and peonies.
  • Divide primulas, including primroses and cowslips, for rejuvenation.
  • Cut oriental poppies back to ground level after flowering. Feed, mulch, and water for new foliage growth.
  • Trim delphiniums to the ground, including leaves and old flower spikes, for a second bloom later in the season.
  • Prune sedums to prevent sagging. Trim stems by about a third.
  • Take cuttings of lavender for propagation.
  • Deadhead roses to promote further flowering. Trim browning heads to a bud or leaf below.
