If you have a small garden or live in a flat, growing grapevines in pots is the perfect solution. The best indoor varieties are Black Hamburgh and Thompson’s Seedless grapes. You can eat the grapes the vine produces or leave them as food for birds. Growing grapevines in a container is a basic task, but the pot can become heavy to lift and move as it grows. Place the pot on a board with wheels. This lets you move the pot easily wherever and whenever you want.
Things you need
45 cm (18 inch) pot with drainage holes
Find a pot that has at least an 45 cm (18 inch) diameter and is at least 30 cm (1 foot) deep. Make sure there are drainage holes at the bottom of the container.
Pour 2.5 cm (1 inch) of gravel in the bottom of the pot.
Mix equal amounts of potting soil and perlite. Fill the pot halfway with the amended potting soil.
Remove the grapevine from its container. Gently tease them free if the roots are growing around the rootball.
Place the grape’s rootball in the centre of the container.
Fill in with the amended soil around the rootball. Pat the soil down to remove air bubbles. Leave at least 2.5 cm (1 inch) between the surface of the soil and the rim of the pot.
Place a stake into the pot close to the rootball. Push it in so it rests on the bottom of the pot. Position the stake so the grapevine has something to grow against and provide support. Tie the branches to the stake with twist ties, string or strips of cloth as the vine grows.
Water the grapevine to keep the soil moist, watering every two or three days. Cut back on watering during the dormant season. Stick your finger 2.5 cm (1 inch) into the soil. Water the vine when the soil feels dry.
Feed the grapes a balanced fertiliser such as 10-10-10 early in the spring. Read and follow label directions.
- Place the pot outdoors during the summer in an area that receives full sun. In the autumn, take the pot indoors. Prune the grapevine in the first season as you take it inside for the winter. Look over the grapevine and find the strongest branch. Cut the others off to the ground.
