Water newly planted vines during dry spells. Established vines grown outside will require little watering as they are deep rooted. Vines grown under cover, and in containers, will need regular watering and will also benefit from a high-potash liquid feed . Apply a mulch in late winter. Avoid using manure as a mulch as this will encourage the roots to grow towards the surface and may also lead to excessive vegetative growth.
Make sure not to allow your vine to flower for the first couple of years after planting.
Grape vines grown outside will not need any help with pollination, as the wind will do this. However, those grown in the greenhouse will benefit from a helping hand. Gently shake the branches to release the pollen. If you wish, you can then stroke the bunches of flowers gently to further aid pollination.
Once the fruit have started to form, thin out individual dessert grapes. This allows for large juicy grapes, and enables them to ripen fully. Use long narrow scissors to remove individual berries when they are still very small. Try to avoid touching the grapes. Instead use a forked twig to support and steady the bunch whilst you snip. Remove about a quarter of the grapes. You can thin later on as well, once the fruit have started to swell. Thinning allows air to circulate around the developing grapes, thus minimizing the risk of fungal problems.
Remove any tendrils that grow. Instead tie the leader and laterals to the supports using string or garden twine.
Remember to ventilate the greenhouse on sunny days. Grapes do not like excessively high temperatures, and greenhouses can get very hot.
In order to start flowering, grapes require temperatures below 5ºC for a period of 4-6 weeks. This is easily achieved outside. If your vine is container grown, then move the container outside for a few weeks during early winter. If your grape vine is in the greenhouse, then open all the vents during December.
If you wish, during early winter, you can remove any old loose bark from the stems using a sharp knife. This will expose any pests that are hiding there.
