June Garden Tips
Garden work for June 2018
June is the month when weeds go rampant, so a bit of time spent with a hoe will pay handsome dividends, even if the back does ache afterwards! Make sure ties on climbing roses or other plants growing on walls, arches, and such like are secure. There may be storms in July and if the plants are torn away from their supports it will mean a lot of time tying them up again.
Hedges need regular attention now, and should be kept in shape, otherwise they can so easily get away from you making the task so much more difficult. Grass needs to be mown, but keep the cutter bar on a high level and the lawn will look greener for much longer. Do not put sprinklers on lawns, even if they do turn a dusty brown, as soon as the rain comes back they will recover with surprising speed. If you do water the lawn you are wasting a precious resource to no real effect.
Roses are at their best towards the end of the month. It helps to keep them cut regularly and feed with a potash feed to keep them blooming longer. If you want to have specimen blooms it is advised to take out the side shoots carefully, as well as the smaller buds, leaving just one strong one at the end of the stem. Keep an eye out for pests and disease. Keep mildew at bay by regular spraying.
As alpine plants finish flowering, trim them back to keep the plants neat and compact. It will also encourage them to make good growth for next spring. Any gaps or vacant spots in the rock garden can be planted with summer flowering annuals or bedding plants to maintain the overall colour. Towards the end of the month cuttings can be taken from the alpine stock to increase the number of plants. Root the cuttings in a sandy compost.
If you are growing tomatoes in the greenhouse plant some Tagetes minuta which is more potent that either the French or African marigold in keeping whitefly and nematode populations to manageable proportions. They also work wonders in the garden when planted as border plants near dahlias and so on.
In the vegetable plot, make sure potatoes are kept ridged up, otherwise the tubers get exposed and ruined. Late Savoy cabbage can be sown now – use a variety like ‘Ormskirk’. Winter cabbage like January King should be planted out now. Leeks should be planted out using a dibber to make a hole about 6 to 8” deep, and then water it in well. Continue to make successional sowings of lettuce. Ones like ‘Tom Thumb’ ‘Little Gem’ and ‘Mini Green’ are fast growing, and the right size for many people. Webbs Wonderful is superb but rather large.
Frost susceptible, fast growing plants like courgettes and so on should be put into their final homes assuming that there is no ground frost forecast. If it has been very dry, make sure that they have a good drink before and after planting them out. But don’t water them all the time. Give the roots time to settle down and then water (if necessary, and allowed) about once a week with a thorough soaking, preferably in the evening or early morning before the sun has got its full power switch on
