June tips for fruit trees
Check your strawberries regularly for weeds. Give strawberries a weekly dose of potassium-rich fertilizer dissolved in water. The first delicious strawberries are often ready for harvesting in June. Pick them with the crown attached, as they will then stay fresh for longer. This also prevents mould from developing on the plant.
Kiwis can be planted until the end of June. Self-pollinating kiwis are the most practical. If you do not use self-pollinating varieties, a rule of thumb is to always have one male plant to a maximum of five or six female
plants.The pollinating male plant should be cut back after flowering. If the kiwi plant is topped at the end of June, new side branches will develop.
In the second year after planting you can train the side shoots horizontally along a trellis. New side shoots will develop from here, and these should be cut off above the fifth leaf. A fruiting branch should be pruned seven leaves above the fruit. Repeat this process all summer long for a vigorous plant.
Check your apple trees every week for mildew (white powder on the branches). This fungal disease can be contained by immediately removing affected areas.
As soon as the apple tree has flowered, it is threatened by pests. The apple sawfly, the pear midge and the plum sawfly like to lay their eggs in the flower hearts. The larvae develop rapidly and eat away at the apples making them wormy. These pests should be tackled immediately!
Read thinning out apple trees
- To obtain a rich harvest, the fruits of prunus varieties (e.g. almond, cherry, peach and plum) should be thinned out now.
- Remove any late flowers in pear trees in June. This will prevent fire blight infection.
- If you want to harvest handsome apples and pears, remove some of the fruits that are growing too closely together.
- Ribes varieties grown as a hedge (e.g. redcurrant, gooseberry and blackcurrant), should have young shoots pinched out as soon as they reach a length of ten to twenty centimetres. This will slow growth and encourage the formation of more flower buds for the next year.
- Check all berry bushes every day if possible for caterpillars (the gooseberry sawfly). They can devour an entire bush in just a few days, which would be a great shame!
- Pumpkins and gourds can still be sown in June. The seeds will germinate faster if they are soaked briefly in luke-warm water.
You should consider that these plants take up a lot of space. A good space-saving idea is to plant them in the border. They can be trained up canes and pergolas or planted against a sunny fence. This will allow you to enjoy home-grown ornamental fruits for months.
- Grapes can be given a summer pruning in June.
