Flower garden job checklist

20 - 26 June 2016

It's time to...

  • Tie shoots of honeysuckle and climbing roses to supports
  • Pinch out the shoot tips of dahlias to encourage branching
  • Deadhead lupins as soon as the flowers have faded
  • Propagate wisteria, clematis, honeysuckle and ornamental vines by layering their shoots into the soil
  • Cut down old stems on spring-flowering euphorbias, taking care not to get the milky sap on your skin
  • Give hanging baskets and patio pots a weekly liquid feed
  • Remove flower heads from flag irises as petals fade
  • Prune back flowered stems on lilac, philadelphus, exochorda, deutzia and weigela
  • Propagate dianthus by taking cuttings of non-flowering shoots
  • Sow seeds of sweet Williams, wallflowers, Brompton stocks and forget-me-nots now
