grapes-redQ. How can I increase the size of my green grapes? Some bunches are great, others have a mix of decent sized grapes and non starters in the same bunch. I trim back the runners on the plant when the main bunches of grapes set to encourage the growth for the grapes rather than the foliage. Any tips to improve the size of all the grapes in the bunch? Angie Gies

A. It is worth noting that the grapes you purchase at your local fruit shop have either been grown in glasshouses or in parts of the world that experience higher temperatures than here in NZ.

Different varieties of grapes do produce fruit of different sizes, but as long as they are sweet and tasty, size should not be as crucial.

To increase the size of your existing grapes, there are a number of things that can help. As bunches of grapes form, you can be selective and remove some of the excess bunches. The energy of the plant can then be directed to the remaining bunches and they should therefore increase in size.

While grapes do not require vast amounts of water, a steady supply applied to roots only (to avoid fungal diseases of the leaves and fruit) can help in boosting the size of the fruit.

Although grapes are not gross feeders of essential plant nutrients, the addition of balanced fertiliser (not excessively high in nitrogen) can help produce bunches of healthy fruit of a reasonable size.
