Gardening in June

As midsummer has arrived the garden should be full of colour and interest.  Now most of the hard work of preparing the garden is done midsummer is the time to take full advantage of any good weather.  It’s really a matter of maintenance at this time of year.  Weeds will be growing quickly now so carry out some regular hoeing to prevent weed seedlings establishing and dig out larger weeds by hand.  Keeping weeds under control not only keeps the borders looking their best but it also prevents them from taking nutrients and water away from your plants.  Applying a thick layer of bark mulch on the border will help to smother weeds and retain moisture cutting down on maintenance.

Any newly plants shrubs, perennials and bedding plants whether in the border or in containers will need regularly watering.  If there is no significant rain, water borders weekly and containers daily.  Container plants will also need feeding through the growing season so either apply a liquid feed weekly when watering or put some slow release feed tablets in each container.  Containers can also be mulched with bark or gravel to retain moisture.

Spring flowering Primulas that have become congested can be dug up, split into smaller plants and replanted for next years display and flag irises that have finished flowering can also be split and replanted to increase stocks.  Continue to stake tall growing perennials as they grow and start to regularly deadhead flowers from perennials and bedding plants to prolong and increase flowering.  Hardy geraniums can be cut back after flowering to encourage a further display later in the season. Climbing plants will need to be tied in weekly as they can soon grow out of control.  Roses should be fed with a rose fertilizer and cut back any suckers sprouting from the base of the plant to ground level to prevent energy being sucked away from the main plant.  Keep an eye out for pests and diseases as these can rapidly take hold at this time of year, keeping plants healthy in the first place will help to prevent pests and disease becoming a problem but if you do notice things like black spot, mildew or green or blackly infestations deal with them immediately with a suitable organic spray from the garden centre.

Lawns should be mown at least once a week now and if the weather is hot and dry raise the blade setting to help the lawn stay greener.  Trimming the edges of your lawn will improve the appearance of your garden and also feed your lawn regularly to maintain health.

In the vegetable garden, start to harvest as plants mature and regularly sowings to maintain supplies.  Tender crops like tomatoes, basil, corinader and runner beans can be planted outside and winter brassicas can be also be sown.  Ensure your greenhouse is kept well ventilated and shaded in hot weather.  Keep ponds, water features and bird baths topped up as they can quickly lose water in dry weather and sit back to enjoy your summer garden.
