This is a good month to trim conifer hedges to keep them under control
Conifer hedges have received a bad press recently, mainly because of the notorious Leyland Cypress. It can grow very tall very quickly and is too vigorous for a small garden; if neglected, it can quickly become a nuisance. As with all conifer hedges it needs trimming at least once a year, preferably twice to keep them in check. If you start doing this while they are small, long before they reach the height and width you eventually require, you will have built up a good thick layer of leafy growth over the surface of the hedge.
Prune Wisteria by cutting back the whippy growths made during the summer so they are within five or six buds of the main stem. This encourages the formation of flower buds for next year. The second prune should be done in February.
Deadhead roses to encourage the display to last longer
Don’t just take off the flower head. If you want to continue the display into autumn, you must prune down to a bud in a leaf axil lower down the stem. This encourages strong new shoots. Prune to an outward facing leaf to keep the centre of the rose bushes as an open shape (this helps protect from disease.) Don’t deadhead Rosa Rugosa as they produce attractive hips in the autumn which help to feed birds in winter.
Roses are greedy plants so after deadheading give them a feed using a fertiliser specific to roses. Don’t use a fertiliser high in nitrogen as this encourages soft, sappy growth prone to attack from pests and diseases. I apply a good layer of well-rotted manure around the base of roses twice a year but if you can’t get hold of any, garden compost will do.
