Grapevines are well suited to container gardening, which, on the surface, looks like a great fruit gardening idea. However, there is one problem with grapes in container gardening. Usually, grapes grown in containers are grown only for the beauty of their foliage and the enjoyment of watching them climb a trellis; they won't bear fruit. Although some varieties of grapes self-pollinate, blossoms need the help of wind or bees to produce fruit.
Still, a trellised grapevine can be a lovely focal point for your container garden. Whether planted or potted, growing a grapevine in full sun is probably the most important requirement for growing grapes.
Because it's very easy to propagate grapes from cuttings, if you have a grapevine in your garden, transplanting a cutting into a container won't cost you anything more than the pot! Low-maintenance plants, in addition to being easy-going about soil composition, planting depth, and fertilization container grown grapevines require only moderate watering.
To start a grapevine in a container, merely preserve a few pruned canes that are 12 to 18-inches long with three or four growth nodes intact. Make a 45 degree cut at the top of the cane for identification purposes and make a straight cut on the bottom of your transplant. Plant the canes, flat end down, keeping one growing node above the soil line. The others will take root and in three to six weeks, you will have the start of a beautiful new grape container garden!
Like garden grown grapes, container grapevines need to be pruned at the beginning of their second season of growth. However, unless you are seriously trying to produce fruit, container-grown grapevines only need pruning to keep them manageable and attractive.
