Pick and Prune Raspberries

Summer fruiting Raspberries should be ready to harvest around now. If you have plenty of Raspberries they are suitable to freeze or to cook gently and make a puree .Old canes will be easily identifiable as they will be a darker brown and the remains of fruit clusters and leaves will most likely look a bit tatty. Younger canes will still have fresh summer foliage on and the stems will be green. You can start by untying the old canes from their wire supports and cut them to ground level. You can them tie in new canes, with spacing of around 10cm apart. Make sure you only tie in strong and healthy canes. The old canes which have been pruned out can be shredded and used as mulch.

Managing Pest and Disease

In the warm summer months, pests and disease can multiply rapidly. Greenfly and Blackfly can reproduce quite rapidly and it can be hard to control them. It is important to have a wide range of plants in your garden that will attract an array of other insects and other wildlife that can help to keep pests and disease at bay. There are many biological controls now available to help control pests. Many of these can be bought in our Garden Centre .
