Jobs in the Garden this June

Published: 1st June 2020

Since our re-opening mid-May it’s been clear you’ve missed your gardens and you couldn’t wait to visit our stores and stock up on the gardening essentials. Now that your gardens are looking full with plants it’s important to keep them looking their best, flowering for as long as possible and crops earning their keep.
   Here’s our guide to jobs to do in the garden this June.
Pruning and Pinching
Wisteria will benefit from a summer prune. Simply cut all the long side-shoots back to about 20cm, this will encourage flowering next year.

Once late-spring and early-summer flowering shrubs like weigela and choisya have finished flowering they can be pruned by thinning the older stems only.

Add some life into your chives by cutting the clump down to the base. This will rejuvenate the clump and you’ll find new leaves in about 2 weeks.

Plants such as fuchsias will create a bushier form and encourage more flowers if you pinch out their tips. Tomatoes will also benefit from having their new shoots pinched out. You can pot these up to create new tomato plants.

Deadheading and Tidying
If your rose is a repeat flowering variety keep dead heading, otherwise leave the flowers to form hips which will be beneficial for wild birds over autumn.

Oriental poppies will require cutting back to ground level once they’ve finished flowering, this will encourage new foliage.

Hardy geraniums can be cut back to encourage new foliage and flowers once they have finished flowering.

Supports and Ties
Climbing and rambling roses will need their new stems tied horizontally to encourage new growth.

Tall growing perennials like delphiniums and hollyhocks will require a cane to support them as they continue to grow.

Honeysuckle, clematis and other climbing plants can be trained by using soft ties around the new shoots.

What to Feed and When to Water
Containers and hanging baskets will need a liquid feed every few weeks, this will encourage continual flowering. We suggest Mirale-Gro All Purpose Concentrated Liquid Plant Food.

Continue to feed fruiting crops and flowering containers with a feed such as Tomorite which is enriched with seaweed extract for flavoursome fruit crops. Dwarf fruit trees on patios will benefit from a top dressing of fresh compost also.

Tomatoes should be fed once the first truss is setting fruit on the plant. Again, Tomorite would be the ideal choice for flavour-packed tomatoes.

Keeping your plants watered is key over the hot summer days we’ve been having. New plants will need extra attention until they’re well established. Remember to water in the mornings or evenings to avoid losing water to evaporation.

It’s always best for the plants, particularly for house plants such as carnivorous varieties and “lucky bamboo” to use rainwater as the minerals in tap water can build up and kill the plant.
  Invest in a waterbutt early to stock up on water before any hosepipe bans and just as a way to save a bit on your water bills.

Pests in the Garden
Lily beetle will be about so crush any you see and keep an eye out for their larvae on the undersides of leaves. The beetles are recognised by their scarlet colouring and the larvae are brown and sticky.

Slugs will be looking for soft new leaves, protect them with copper tape or slug pellets which can be found in the garden care department. Try the Sluggo range from Neudorff which is safe to use around vegetables, strawberries, lettuce and ornamental plants. Another benefit of the Sluggo range is that it’s also extremely resistant to rain.

Aphids are a real problem for roses and other fresh growth, so spray the all sides of the plant with Bug Clear Ultra, or squeeze them between your fingers.
