June Gardening Tips

June gardening tips are provided by John Morgan, Category Manager Horticulture at Van Hage.

Beds and borders

  • Prune shrubs as they finish flowering
  • Remove faded blooms of annual and perennial plants
  • As Rose petals fade remove the flowering stem and feed
  • Support and tie up climbing and tall growing plants


Normally a month when the grass needs cutting all the time and may need watering. However with the mostly cold spring so far this year, if your lawn is not looking lush and green, feed again with Evergreen Complete lawn food and sow grass seed on bare patches, chose a seed that best fits your purpose, Tough grass where children run about and Shady place when under a shadow from trees.

  • Mow weekly and trim the edges
  • Liquid lawn food will give a quick green up
  • Use lawn weed killers on problem patches
  • Sow grass seed on bare patches


Most fruit trees should now be starting to produce the small fruit-lets, many of these will fall off a term called, “June drop”. This process is the tree naturally adjusting to the amount of fruit the tree can cope with. In dry weather apply water to avoid too much drop.

Netting strawberries as they ripen pays dividends, no one wants to grow them for the birds to eat.

Check twice a week for and pests or diseases that may attack your plants, if you are unsure cut of an effected piece, put it in a plastic bag and bring along to Van Hage. We will identify the problem and suggest solutions.

  • Protect strawberries as they ripen
  • Do not be alarmed by “June drop”, as most fruit trees shed several small fruit lets as a natural adjustment to the amount of crop they produce.
  • Support and tie in new growth on raspberry and blackberry
  • Check for pest and disease

Bedding plants

As flowering shrubs finish, remove the faded blooms, this should include Rhododendron and Lilac. Most plants will greatly benefit from a feed after flowering they will reward you by producing lots of blooms next year, Miracle-Gro slow release fertiliser is an excellent choice.

Continually check that tall growing perennials are securely staked and tied, there is nothing worse than waiting for something to flower, to have it snap off in the wind.

  • The best time of year to plant bedding plants in the ground, pots and hanging baskets
  • The removal of faded blooms will increase as the month progresses
  • Increase watering when the warmer weather arrives


Early crops should now be ready to harvest; the flavor is second to none when eat your own crops freshly pulled.

Sow and plant again as soon as space becomes available, for crops later in the year.

Tomatoes, Cucumbers and Peppers grown under glass will need to be regularly water and fed with Tomato feed. All greenhouse crops must be kept well supported.

  • Pick crops as they mature
  • Continue to sow small batches of quickly maturing crops such as Radish
  • Support and tie in new growth, such as runner beans
  • Increase the watering, feeding and ventilating of any greenhouse crops, such as Tomatoes. Such plants will also need to be supported and tie up.

House plants

It is easy to forget that any plant inside the house will require a lot more water especially on hot summer days.

  • The summer months mean that most indoor plants will need more water
  • Feed regularly
  • Move some plants away from the hottest south facing window
  • Remove any faded blooms


  • The summer months always mean a large amount of weed growth. Hoe or use a weed killer, ask for advice if help is needed for the best treatment, a sample in a plastic bag or a photo makes identification easier.


We all know when summer is truly here when the rose begin to bloom in the garden. For a succession of flowers remove all faded blooms and feed with rose food.

As with the fruit check twice a week for and pests or diseases that may attack your plants.

Climbing Plants

The new growth produced by climbing plants allows them to show their true potential, covering walls, fences and those unsightly areas. Ensure all the new growth is trained or tied in to avoid wind damage.


The leaves from spring flowering bulbs will soon have died down enough to pull off, making more space to cultivate and grow.

Summer flowering Dahlia, Lily and gladioli will need to be staked and tied to avoid any wind damage. Watch out for bright red lily beetle, which will start to appear this month.

Pest and disease

  • The summer is always the time of year when the garden comes under attack, organic and chemical methods are available, ask for advice if help is needed for the best treatment, a sample in a plastic bag or a photo makes identification easier.


Watering is an essential task in the summer.

Pots and containers should be watered at least one a day. Plants in the ground perform much better when given a lot of water occasionally rather that a little bit every day, it can be very relaxing in the garden hose in hand at the end of a busy day.

If time is short an automatic watering system is an easy way to save time.

  • Watering is essential to the whole garden if we get a prolonged period of hot weather, better results are gained by applying a larger amount of water infrequently rather that a small amount of water regularly.
