what to cut back in summer

Top Tip Always make sure your tools are sharp and clean. Use secateurs on pencilthick growth, loppers on larger wood and a saw for thick branches. CONVENTIONAL wisdom says we prune trees and shrubs in autumn and winter when they are dormant, but there are several varieties that ought to have a haircut in summer. These largely fall into two categories; those that are susceptible to silver leaf disease; and shrubs that flower in early summer and create each year’s blooms on strong young growth produced the previous year and early the next. A third group are evergreen shrubs that are less hardy can be damaged by cold if trimmed in winter. This week I have been busy pruning our recently flowered philadelphus and weigela, giving a straggly ornamental flowering cherry muchneeded tidy up, and…

more summer pruning tasks

AS well as pruning varieties prone to silver leaf and shrubs that flower in early summer, this is a good time to tidy up other shrubs and climbers. Early flowering clematis such as C. montana may be starting to straggle and outgrow their space, so run your shears over them to remove straying shoots, then deadhead to create a neat appearance. We have a compact The Countess of Wessex clematis in a pot that has flowered, but will hopefully flower again in late summer. To encourage this, I deadheaded the spent flowers, and forked and watered some bone meal into its compost. Keep an eye on your roses, too. Watch out for pests such as aphids and sawfly, controlling them immediately, and treat blackspot to help keep your plants robust. Pull out any rose…

dealing with clematis wilt

CLEMATIS are one of our most popular, exotic-looking plants, and with good reason. There are different varieties that flower in almost all seasons, and they can be grown in borders or containers and trained up walls and fences or up elegant teepees in the middle of beds However, they can be tricky to cultivate. They like to have their roots cool and damp, but their top growth in sun or partial shade – even though the blooms of some larger varieties tend to fade in sunlight. It is extremely disheartening to see previously healthy clematis shrivel and blacken almost overnight, and there are two main reasons – the disease clematis wilt and the environment in which they are growing. Clematis wilt is caused by the fungus Calophoma clematidina and is more likely to…

how to prevent unsightly powdery mildew

A COMMON plant affliction from spring onwards is powdery mildew, a fungal disease that shows itself as a white, powdery substance on the surface of leaves and flowers. There are many strains of the disease that affect many varieties of ornamental and edible plants, and it is largely caused by environmental stresses on the plant. Reduce the risk of mildew by planting with lots of room between plants, in a sunny, open spot with good ventilation and free-draining soil. Watering is important, as drought will stress the plant. When pruning shrubs, keep them healthy by creating an open shape with an uncongested centre to assist ventilation and reduce the risk of rots and mildew. Avoid wetting the leaves if you water in the early morning or evening, though dampening foliage during the rest of the…

it’s time to count butterflies

Got a story? email ruth.hayes@futurenet.com AG READERS are being called upon to mobilise and take place in one of the UK’s largest ‘citizen science’ projects. The Big Butterfly Count, which runs from July 17 to August 9, is seen as one of the best ways of ‘taking the country’s natural pulse’ and gauging the health of its natural environment. All you have to do is spend 15 minutes in an outdoor space during sunny conditions and then count the types and amount of butterflies you see. You can do as many counts as you like on different days during the three-week period, and even unsuccessful counts where you saw no butterflies at all are important and should be logged. A time of peak butterfly appearance Joanna Bower of Butterfly Conservation, which is organising the count, said:…

the (socially distanced) national dahlia show must go on

ALTHOUGH most of the UK’s major gardening shows and celebrations were cancelled in the face of Coronavirus, one group of growers have found a way around lockdown. The National Dahlia Society is, for one year only, holding a Socially-Distanced Dahlia Show. Taking place at the Abercorn Garden Centre in Chelmsford from September 10-14, just 30 growers will be exhibiting their plants. Dave Gillam said: Abercorn Garden Centre have offered the use of their coffee shop, currently closed, to stage the best competitive display of dahlias in the country. We anticipate that over 75m (245ft) of three-tier tables will be full to the brim with flowers from all areas of the UK. This will be a real spectacle as the UK is accepted in the world to produce dahlias to their highest potential.” He added: “We…
