Plant tomatoes in containers at least 10 to 12 inches across with sufficient depth to allow good root development. Staking Staking allows more plants in a given area and the fruit is easier to harvest, larger, cleaner and free of ground rots. Staked plants also lend themselves to better insect and disease control. Stakes can be made from a 1 x 2 inch piece of wood 6 feet long, pointed at one end. Place it firmly about 4 inches from the plant at time of transplanting.
Many gardeners prefer to support tomato plants in cylindrical wire cages.
Mesh should be large enough so it can be reached through to pick fruits inside. This method saves time required for staking, pruning and tying. Pruning When plants are staked, remove side shoots or suckers when they are 3 to 4 inches long. Don't cut suckers with a knife because this practice can spread diseases that may be present. When plants are grown in cages less pruning is required.
