JUNE IN THE FLOWER GARDEN

ACTION NOW	SOW AND PLANT	IN FLOWER NOW
Plant out remaining bedding plants	Ageratum - plant	Roses are the stars of the garden flowers this month. They are at their most beautiful with the first flush of flowers. Most bedding plants will also be in full bloom - geraniums, fuchsias, begonias, ageratum and garden pinks to name but a few. Walls and fences will be clothed by the large flowered hybrid clematis such as The President and Nelly Moser. For scent in the climbers, the climbing honeysuckles are hard to better. Amongst the shrubs, Magnolia sieboldii will be in full bloom with its saucer-like flowers. Two other favourites, budleia and the orange ball tree (B. globosa) will make their first flowers from mid month onwards - both will attract butterflies into your garden to complete the summer picture.

All danger of frost will have passed now, so get those remaing bedding plants into the flower beds at the beginning of this month. Remember to soak the compost prior to planting and water the flower bed soon after planting.thorough

Every four years or so, lift and divide the rhizomes (tuberous roots) of bearded irises after flowering has stopped. Gently ease a fork under the rhizomes and lever the clump from the soil. Select three or four healthy looking rhizomes, towards the outside of the clump, which have foliage growing from them. For each rhizome selected, cut through each about 10cm (4in) from where the foliage is growing - a sharp knife will be needed. Cut the leaves by half (to preserve moisture) and replant with the rhizome just showing above the soil. In this way, you have three or four healthy plants next year.

For all forms of sweet peas, they will flower better and longer if the tendrils (thin green curly growths) are pinched out with your finger tips. If you do this, the main stems will need to be tied to their supports. If you are growing sweet peas in a cordon form (one single stem), select the healthiest main stem and pinch out any side stems as they appear - be careful though not to pinch out the flower shoots. They are easily identified by their swelling of small flower buds. Feed them regularly from now onwards and most of all ensure they do not go short of water.

Every three years or so, lift and divide clumps of primulas. Simply lift up the clump with a fork and tease it apart with the hands. Replant wherever needed and water in well.

When mowing the lawn with an electric mower, a good tip is to start mowing nearest the power source, gradually moving away from that point. This will reduce the risk of cutting the electric cable with the mower. Water the lawn in the eveing to minimise the amount of water which evaporates.

Deutzias, Philadelphus and Weigelas should be pruned soon after flowering stops. Prune away roughly 30%. This will encourage new shoots which will bear flowers next year.

Modern roses are grown on more vigorous rootstocks (the joint between rootstock and the main rose will be just above ground level). Often, the roostock sprouts shoots of its own (suckers) which should be removed. Because the suckers come from beneath the soil, gently remove some of the soil around the sucker and cut it off as near its point growth on the rootstock as possible.
