What To Do in the Garden in June

June brings warmer temperatures, lighter evenings and longer periods of the British summer sunshine. The longest day of the year falls on the 21st June and encourages us to spend more time soaking in the sunshine in the great outdoors. This month sees our gardens flourish in greenery, blooms and beautiful floral scents and is the perfect time to enjoy your hard work with al fresco dining, entertaining and morning coffee in your garden.

As the warmer temperatures bring blooms and plenty of ongoing maintenance, the weather is frost free but can still be unpredictable. Take a look at all the things you should be doing to keep your garden in bloom this June.

What To Do in the Garden in June

Plants and Flowers:

  • One of the main things to keep on top of throughout June is deadheading. Encourage your plants to keep blooming by removing spent flower heads and leaves routinely. This is especially important for rose varieties.
  • Trailing leaves and flowers in your hanging baskets should be trimmed to encourage new growth.
  • Divide your annual spring flowering plants such as Irises, Primrose and Daylillies to encourage healthy plants year on year. This also gives you the opportunity to increase the number of plants you have and reduce competition and overcrowding.
  • Lift and divide bulb and legume plants like Bluebells and Snowdrops after the leaves have begun yellowing and activity has ceased. This helps reduce competition and encourage healthy growth next year.
  • June can often still bring unpredictable weather and storms. It’s advisable to stake tall perennial plants to reduce potential wind damage.
  • For climbing plants such as Clematis and Honeysuckle use trellis and soft ties to train new trails.
  • Towards the end of the month cut back Geraniums that have finished flowering to encourage new growth for the remainder of the season.

Lawn Care:

  • Depending on the weather, cutting may need to be left for longer periods of time to reduce stress on the grass.
  • If the weather is particularly dry, raise the blades on your lawn mower to avoid reducing moisture levels and drying out.
  • For recently seeded or turfed areas water well and consistently to help with growth whilst the grass is young.
  • Use specialist lawn fertiliser to feed your grass and create thick, luscious growth. A slow release of nitrogen rich fertiliser will help to boost growth and greenery despite the drought and higher traffic levels it will face throughout June.
  • For easier maintenance throughout the summer trim edges and consider adding decorative borders and edging to elevate the look of your lawn.

In the fruit and vegetable patch:

  • Harvest potatoes and crops as and when ready, this may change frequency through dry and wet spells.
  • Salad crops and leaves should be harvested and replanted every two weeks for a consistent supply of fresh salad to accompany your BBQs throughout the entire summer.
  • Tomato plants should be fed and watered regularly. When the flowers start to appear, begin regular feeding to get the best flavour and harvest from your crop.
  • Fruit trees should regularly be pruned to encourage further flowers and fruits to grow. Fruit should be thinned to help improve the quality of the remaining produce and stop branches from becoming overloaded. Your trees will have naturally dropped some of their own fruit during the ‘June Drop’ which will make it easier to tell when further thinning is required.
  • To protect developing fruits from birds and wildlife, place netting around trees and the vegetable plants.
  • Fruiting plants in containers need to be fed regularly with a high potash liquid feed to encourage healthy growth of flowers and increase resistance to the weather and pests. This extra boost in potassium is particularly important for light and sandy soils.
  • Either peg and propagate strawberry runners or remove for main plant focused fruit bearing.

Pests and Weeds:

  • To keep on top of your lawn, apply a specific lawn weed killer to deter rapid weed growth throughout warm dry spells of weather. A combined lawn fertiliser and weed killer is the ultimate way to encourage grass growth and prevent weeds.
  • On flowering plants remove aphids on the underside of leaves or young buds by rubbing them off by hand or with an insecticide spray.
  • For young and recently planted flowers, invest in an effective pest control to prevent slug and snail munching on growth, particularly in shaded and damp areas of your garden.

Watering Tips:

  • Try to water your plants with natural rainwater which is easiest collected in water butts.
  • In extended periods of dry, hot weather water plants and in particular fruit and vegetable bearing frequently.
  • For those plants in greenhouses, frequently open the door for ventilation and water in the morning and evening to prevent drying out.
  • Make sure pet bowls and bird baths are well topped up and are in the shade as much as possible.


As temperatures get warmer and the summer holidays loom, remember if you are going on a break, whether that be in the UK or abroad to consider your watering. If possible set up a sprinkler system for automated watering or organise a family member or friend to look after your stock when you’re away.

Something for the little ones:

Though it may seem a long time off, get the little ones involved in the garden by beginning to grow pumpkins for Halloween. Pumpkins can be sown indoors from April, however they can do extremely well by being sown in early June outside as they need a warm, sunny position with shelter from cold winds. After germination pumpkins should be covered with plastic sheeting. For more information about growing pumpkins, please refer to the seed packets for tips on the particular variety that you are growing.

Enjoy your garden throughout the entirety of June, taking in the sights and smells of your plants in bloom and begin to enjoy the first fruits and vegetables from your garden.
