Grape growing is becoming a big backyard hobby. If you produce a harvest of grapes you can make jam, jelly, juice or even wine. The Thompson seedless grape is one of the varieties that is readily available to home growers and does quite well with the proper care. If you want to plant your own Thompson seedless grapes, keep in mind where you plant the grapes, the drainage of the soil and fencing, as grapes must have something to climb on.

Skill level:
Moderately Easy

Things you need

  1. 1

    Choose a location for your Thompson seedless grape plants. Choose a southern slope in your yard or garden that will get full sunlight and good drainage.

  2. 2

    Install simple, but strong fencing (see Tips). Build a fence that has only two or three rungs.

  3. 3

    Purchase grape canes in the early spring and plant in the soil immediately. Remove the grape plant from the container by tapping on the container to gently loosen and remove the root system.

  4. 4

    Dig a hole that is as deep and wide as the root ball of the grape canes. Spread out the roots of the grape plant gently and place the plant in the hole. Cover the roots with soil.

  5. 5

    Plant subsequent Thompson seedless grape plants, leaving 6 to 8 feet in between each plant to allow plenty of room for the vines to grow and spread out.

  6. 6

    Plant subsequent rows of grapes, leaving 8 to 12 feet in between.

  7. 7

    Water the newly planted grape plants until the soil is well-watered. Give the grapes about 1 inch of water per week if there is no rain.

  8. 8

    Train the grape vines to climb on the fencing by tying the vines to the fence using hook and loop ties. Rearrange the hook and loop ties whenever necessary, to either prune the vines of the plant or just move the growing vines of the plant around.

Tips and warnings

  • Figure out how many grape plants you want by figuring that a healthy, productive grape vine will produce about 11.3 Kilogram of fruit.
  • You can make a simple fence for your grapes that is much like professional grape growers use. Use two 4-by-4s for the posts, and attach 9- to 12-gauge wire in between. This is an uncomplicated fence to put up and it also makes it simple to add more posts when you want to add more plants.
  • Do not plant Thompson seedless grape plants at the bottom of the slope where there may be standing water from time to time. Too much water, especially during the spring, will prevent growth.
