Raspberry leaf and bud mite can also cause yellow blotches on the surface of the leaves, so can be confused with the mosaic virus.
Best root barrier for raspberries free#
Discard affected plants and plant elsewhere with certified virus free stock. The most common is the mosaic virus that causes yellow patterning on the foliage leading to stunting and a poor crop. There are various viruses that can attack a raspberry plant. Prune out affected canes as soon as you spot the rot spreading up from the base. Raspberry cane blight is another fungal disease that attacks the cane itself, causing it to die right back in the middle of the summer. Ensure your canes do not get too overcrowded by limiting them to 6-8 per stool. Pruning summer fruiting varieties straight after fruiting should help control this, as you remove all the affected leaves in one go. Pick off or rake up affected leaves to avoid spreading the fungus.
Raspberry rust is a fungal disease that causes raised orange pustules on the tops of the leaves in spring or early summer. You can also hoe carefully around the plants to disturb the beetles and expose them for the birds to enjoy. There are also floral lure traps that you can put in place in spring to attract the adult beetles as they emerge from the soil. This is one reason to delay netting the fruit until it is almost ripe – that way the birds can help you out by eating the beetles and grubs. My mother would have told me to look at it as a bit of extra protein, but now we might be more squeamish.
They can be up to 8mm long, so you might even spot them in the fruit bowl after you have picked them. If you spot a brown desiccated top to a ripe fruit, the chances are it has been attacked by the larvae of the raspberry beetle. To store in the fridge, place in a single layer on a tray and cover. Allow them to ripen fully on the plant, so that the hull remains on the plant and the fruit comes away easily without being damaged.
The summer fruiting varieties need to make their fresh fruiting canes for the following year and the autumn ones will be concentrating on getting their roots established.
These can be used to fill any gaps in the row, or indeed to start a new row elsewhere.ĭo not expect much of a harvest in the first year. Both summer and autumn varieties will spread outside their rows, so you will need to rein them in by removing the suckers each year. Don’t be tempted to tidy them up before that as the pruning can spur them into shooting too early and getting caught in a late frost. If you struggle to see the difference between the two, the old, fruited canes will have a brown woody stem, and will show the remains of the fruiting spurs, the new ones will still be green with no side shoots.Īutumn-fruiting raspberries fruit on the current season’s growth and should be pruned by cutting all the canes back to ground-level at the end of winter. There should now be no more than 6-8 canes healthy canes on each stool. Cut back the tip of each cane in February. When the canes grow taller than the structure bend the tops over and tie to the top wire. So, in order not to get muddled and overcrowded they should be pruned as soon as they have finished fruiting.Ĭut back all the fruited canes to ground level and tie in the new canes to the structure.
