The Gardeners Diary – April/ May/June 2008

There are many things we need to be doing in our gardens, here are just a few reminders of what you should be concentrating on in the garden in the coming months.

April:

  • Start weeding the soil around soft fruit and apply a dressing of fish, blood and bone.
  • Start mowing the lawn, sow annual flower and herb seeds, divide herbaceous plants.
  • Deadhead daffodils as they fade.
  • Start staking herbaceous plants in borders.
  • Prune any spring or winter flowering shrubs after flowering and start clearing pond.
  • Plant dahlia tubers towards the end of the month and plant evergreen plants and hedging.
  • Start planting hanging baskets, marginal plants and pond plants.
  • Sow all vegetables now except tender varieties like tomatoes, runner beans, French beans, cucumbers, squashes and courgettes.
  • Sow main crop potatoes in April for harvest in late September.

May:

  • Lay new turf or sow grass, continue sowing annual herb seeds and clearing ponds.
  • Finish plant hanging baskets and dividing herbaceous plants and being to clip deciduous hedges and topiary.
  • Plant out courgettes, squash and outdoor tomatoes towards the end of May and reduce runners on strawberry plants.
  • Sow lettuce, herbs, carrots, peas and spinach and any other vegetables you enjoy eating.
  • Cover rows of early potatoes with mounds of soil to prevent the growing tubers from turning green.
  • Continue to mow your lawn.

June:

  • Prune early-summer flowering shrubs such as viburnums and philadelphus by cutting a third of the old wood.
  • Hoe the borders to keep down the weeds.
  • Thin apple, pear, plum and grape crops if needed.
  • Continue to sow annual flower seeds and clip evergreen hedges.
  • Liquid feed container plants and carry on mowing the lawn.
  • Make sure you keep the garden flowering by deadheading flowering herbaceous and annuals plants and repeat-flowering roses to encourage more blooms to grow.
  • Plug any gaps in your borders with late-season dahlias and salvias.
  • Trim slow growing evergreens such as box and holly but leave yews until August.
  • Harvest early vegetable crops and dig up the first early potatoes after the middle of the month.
  • Use the space for courgettes, squash or cabbages.
  • Now would be a good time to buy broccoli, Brussels sprouts or leek plants.
