Langlands June Gardening Tips

The days are getting warmer and longer, gardens are more colourful, plants are growing...

Get out there and enjoy!

Trees and Shrubs

  • Carefully snip off the dead heads of azaleas and rhododendrons after flowering.
  • Cut back broom when it has flowered.
  • Reduce long shoots of climbing plants.
  • Towards the end of the month, trim box-topiary.
  • Feed roses and deadhead regularly to encourage more blooms.
  • Prune plum trees in June or July when growing strongly.


  • Many types of hedges can be given their first clipping of the season, which will help them keep their shape and stimulate fresh growth.
  • Older hedges may need just a small trim, but young, actively growing hedges should be given a substantial prune.
  • To keep the top of hedges flat and even, try using a length of string as a guide.
  • Don't forget to weed under your hedges at this time of year. After weeding, add a layer of mulch to reduce the chance of any weeds from reappearing.

Fruit & Vegetables

  • Separate and plant strawberry runners.
  • Thin out any developing fruit on fruit trees after the June drop.
  • Fertilize vegetables as necessary and keep them watered, mulched and weed-free.
  • Plant any vegetables outdoors that were pre-grown in the greenhouse.
  • Tie up tomatoes and pinch-out side shoots regularly.
  • Harvest herbs and early potatoes.


  • It may be necessary to mow twice a week now. If rainfall is low then water the lawn thoroughly, but not frequently, to encourage deep root growth.
  • If weeds are still prevalent, apply a lawn weed treatment when the soil is moist.
  • If clover exists then rake the lawn before mowing.
  • If you plan to mow a wildflower meadow twice a year, carry out the first mow in mid-June.

Flowering Plants

  • Plant the last of the annuals.
  • Stake tall-growing varieties to prevent them from being flattened by wind and rain.
  • Pull out weeds, hoe and mulch the beds.
  • Cut back early flowering species, such as delphiniums, to a hand's height above soil level
    (they will flower again in late summer).

Senetti should be treated as an annual. If regularly deadheaded, it will bloom all summer long!
