Caring for grapevines
1Grapes are rampant plants, so you’re likely looking at a tangle of leaves and stems come early summer. Make sense of them by tracing them back to see if they support a decent bunch of grapes – cut two leaves past the bunch of any that do. Weak shoots can be rubbed out.
2 Non-fruiting, strong shoots can be left in place if you have the room, otherwise these, too, can be cut out. If you’re training a young vine now is also the time to tie in any shoots that you want as a permanent framework. Foam-coated wire is ideal as it’s strong yet soft.
3 Your grape will now pump all its nutrients into the developing bunches. As they swell, thin them out to one per 61cm (2ft) of stem. On indoor vines keep your eyes peeled for scale insect and red spider mites, and keep vines well watered and ventilated.
