How to Prune Grapes Summer
Hi, I’m Tricia, a California organic gardener and today we’re going to talk about summer maintenance for your table grapes we’ve had an extremely wet season this year and my table grapes have gone bonkers I’m growing four different types of table grapes here and there’s a lot of vegetative growth making for a very dense canopy over the grape vines earlier in the spring, the shoots were thinned when they were about six to twelve inches long you should have about six to eight shoots per foot of canopy at the same time as thinning the shoots, I also cut the suckers off at the trunk.
And i’m going to continue to trim these suckers throughout the season, as necessary you see there’s not enough sunlight getting into this little fruit clusters the sunlight is what helps improve the flavor and the quality of the fruit by having so much foliage around the cluster, I’m also at risk for disease the first step is to take these long shoots and tuck them into the trellising and keep them out of the fruiting zone that helped a lot but you can see there’s still a lot of hanging vines I’m going to trim back this shoot that has no clusters on it.
If you’re going to trim back a shoot that has clusters, be sure and leave about 1517 fullsized leaves before you make your cut cut as little as possible and try to cut at the point where the leaves are half the size of the mature leaves these smaller leaves haven’t started producing food yet so the vine won’t miss them as much as it would miss these larger food producing leaves the grape vines are looking a lot better the cutting is going to stimulate the growth so you don’t want to do this too late in the season if the fruit is just beginning to ripen, it’s too late to cut.
Now that I’ve tamed the vines, it’s time to thin the fruit cluster thin when the fruit has just set and before it gets too big for goodsized table grapes leave one cluster per shoot in order to improve the size of the grapes, snip off the very bottom of the cluster I’m happy to have completed my summer maintenence on my table grape vines now I look forward to grape jam, grape jelly, grape juice, and those frozen grape treats so enjoy your grape vines and Grow Organic for Life!.
Hi, I’m Tricia, and organic gardener. Grapes are a beautiful edible landscape plant, as well as producing delicious fruit. Today I’m going to plant a new grapevine. If you’re not ready to plant your grapes as soon as they arrive, that’s ok, you can heel them in. You can either dig a shallow trench, put the grape vines in and cover the roots with soil, or you can do like I’ve done and put the roots in a bucket, cover them with soil and protect them with a little bit of straw.
Grapes are tolerant of a wide variety of soils, but it is important to check with your Master Gardener or local ag extension to find out what varieties will do best in your climate. Your site selection should be in full sun with a southern exposure, away from trees. And avoid depressions where cool air can collect. Ideally, preparation for planting your grapes will start the year before with a soil test and an appropriate cover crop. Grapes like moderate fertility and a pH of about 5.5 7. In most climates you can plant grapes in late winter or early spring.
For northern climates you might want to wait until a little bit later in the spring. Just dig a hole the same size as the roots and don’t add any fertilizer. You don’t want to get more leaves than fruit! Soak the roots of your grapevine for about 2 to 3 hours before planting, and then you can prune off any damaged roots. But it’s important to leave as much of the root system as possible. Make sure that the roots are loose and not clumped together. The hole should be deep enough to plant the vine to the same level it was planted before,.
With a few inches of soil over the longest roots. Gently back fill the soil with the topsoil first. And if it hasn’t rained recently make sure and give your plant some water. You want to train your newly planted little grapevine to grow into a big grapevine with a straight single trunk reaching the trellis. In order to do that we’re going to prune this plant so that it has one straightish cane. By the second year you need some kind of a support system. This two wire support system is very common and easy to build.
To train your grapevine to grow straight up to the trellising, you may need to do a temporary support like bamboo and then just tie it together with a little twine or some tape. These are flame grapes, so I’ll be training them to a bilateral cordon. That is I want a nice straight trunk. And then I’ll choose two buds that will be trained into big, permanent branches on either side of the trunk. It’s really important to tag your plants. I use these permanent zinc plant tags.
Its really important to know what variety you have so that you can prune appropriately. Whether you have a big vineyard or you’ve just planted a few grape vines, grapes will benefit from cover cropping. So get ready for winter pruning, and Grow Organic for Life!.
