Jobs in the garden in June include:

  • Plant out the more tender vegetable plants – such as courgettes, squashes and French and Runner beans remembering to harden them off before planting them. Courgettes and squashes are greedy feeders so make sure lots of organic matter is incorporated into the soil. Outdoor tomatoes can also be planted out.
  • Earth up main crop potatoes. Sow quick growing vegetables like salad greens and radishes to fill spaces in empty vegetable beds. Continue to sow main crop carrots and peas so you have a succession of vegetables later in the year.
  • Tomatoes grown under cover will need regular watering and feeding with a potassium rich plant food to encourage flower and fruit production.
  • In the fruit garden cover soft fruit with netting so that you and not the birds get to enjoy the fruits! And thin apples and pears to increase fruit size.
  • As soon as sweet peas start to flower pick them as this encourages more blooms.
  • Pinch out the tips of your Fuchsias to encourage a bushy habit and more flowers
  • Towards the end of the month, cut back hardy Geraniums that have finished flowering. This will encourage a fresh growth of leaves – and more flowers if the Geranium is one that repeat flowers.
  • June is a good month to prune spring and early summer flowering shrubs ie as soon as they have flowered – many flower on the previous year’s growth so if pruning is left until later in the year you will be cutting off growth that will produce flower next year. Shrubs to prune now include Forsythia, Philadelphus, Ribes (flowering currant) and Weigelas. The secret to pruning these shrubs is to prune from within – removing the oldest (thickest) stems as well as any crossing branches. This will result in a less congested looking plant with a more natural shape. When pruning also remember the 3 D’s –   Dead, Damaged and Diseased. Any of these parts of a shrub should definitely be removed whenever you are pruning (and can be removed at any time).
  • Regularly dead head roses (unless they are good for hips like Rugosas). Cut off the old flower plus 2-3 leaves worth of stem rather than just snipping off the flower head.
  • Tie in the wayward stems of climbers, roses and wall shrubs – using soft twine tied loosely – not wire which cuts in and damages plant stems.
  • If we have a spell of warm dry weather remember to water plants in pots, hanging baskets and other containers.   Recently planted trees and shrubs will also need watering. All should be watered thoroughly: a good soaking less often is better than a frequent light sprinkling of water!
