Making the Right Cage

Making the right cage for your tomato plants is a step that should be taken with full attention. A three-foot-tall, cone-shaped cage that is found in many gardening supply stores is good enough for some determinate plants but cannot handle indeterminate plants. Keeping this fact in mind, a cage of height of about 4 feet and a width of 14-18 inches is suitable for determinate tomato plants. Plus the height of 6 feet is enough for an indeterminate variety of tomato plants.

Place Cage after seedling

It is noteworthy that the tomato plant is such a delicate plant that it can hardly bear any pressure. So, it is advised to place the cage right after the seedling. Be careful it may not damage roots. This plant grows too fast and you should not take the risk of cage installation during its growth as it may damage its soft branches.

Fixing cage in soil

In order to fix the cage in the soil, place it right around the plant and draw some pressure to dig it down in the soil. For larger cages, extensions or stakes may also be driven along with the cage. Carefully guide the branches of the plant through the cage as it grows to fill it

Benefits of Making Tomato Cages

Can’t we grow tomato plants without a cage around it? You can, but its production suffers without a cage. Following are some of the benefits of using a cage:

Provides Support and Avoid Diseases

A tomato cage provides support to your plant and helps it grow vertically upward. This prevents them from bending or crawling along the ground. Without a cage, they may come in contact with the soil for a longer time which suspects them to fungus and other diseases. By keeping your plants off the ground, you prevent rainwater from splashing the plant leaves, which is a common way for disease spreading.

Saves Space

You can easily save much space in your garden by growing plants in a cage. By saving space, you can plant more and get a larger harvest at the end of the season. Also, crop rotation is much more practical in a small garden.

Support Branches

Tomato cages have horizontal supports. So you can easily rest the branches of your tomato plant on these horizontal supports. Doing this reduces the chances that the branches will split or break due to the weight of tomatoes on the vine. It is also helpful in windy weather conditions. Unlike stakes, you will not have to tie your plants to the cage as it grows. However, you still can tie your plant to your tomato cage if there are chances of heavy winds.

Taking Care of Your Tomato Plant

Most importantly, it is much easier to take care of plants that are grown in tomato cages than if grown along the ground. If your plants are growing vertically in a tomato cage, you will not have to worry about stepping on vines, fruits, and branches. Also, you can water the base of your plant easily. This will save the leaves of the plant from getting wet and your plants will not suffer from fungus and rot.

Protection of Plants

It can be difficult to protect an established plant from cold if you live in an area with low temperatures. A tomato cage can protect your plant from cold because it provides a very nice frame for you to wrap the garden fabric around your plant, in preparation for an early fall frost.
