How to Stake and Support Tomatoes: Cages, Stakes & Trellises

A tomato plant left to sprawl on the ground is a tomato plant inviting trouble: fruit rots against damp soil, slugs and disease move in, and you trample half the crop trying to harvest. Support fixes all of that at once. The trick is to put it in early and to match the support to the plant.

Decide before you buy: determinate or indeterminate

The right support depends entirely on the type. Determinate ("bush") tomatoes stay around 3–4 feet and carry their crop over a few weeks, so a sturdy cage or a short stake is plenty. Indeterminate ("vining") tomatoes climb 6 feet or more and keep going until frost, so they need tall, strong support and ongoing attention. Check the tomato catalog page or the seed packet before you choose hardware. The full growing guide is how to grow tomatoes.

Install at planting time

This is the rule everyone learns the hard way: get the support in the ground when you transplant. Drive a stake or set a cage while the root ball is small and shallow. Wait until midsummer and you'll spear roots, snap branches, and wrestle a 5-foot plant into a cage built for a seedling. Putting it in early also guides the plant upward from the start.

The three real options

• Stakes. A single tall stake (at least 6 feet, sunk a foot deep) next to the stem, with the plant tied loosely as it grows. Cheap and space-efficient, but it demands regular pruning to a stem or two; pair it with pruning your tomatoes.
• Cages. The most forgiving for busy gardeners: the plant supports itself inside the frame with little pruning. The flimsy cone cages sold everywhere are too weak for indeterminate plants, though; a cage of concrete-reinforcing mesh or livestock panel with large openings is sturdy and easy to reach through.
• Trellises and string. A horizontal trellis or an overhead string (the plant wound up a length of twine) is how many market growers do it: excellent airflow, easy picking, ideal for a row of indeterminate plants.

Tie loosely, and tie often

However you support them, fasten stems with soft, loose ties: strips of cloth, garden tape, or twine in a figure-eight that cushions the stem against the stake. Tight wire or string girdles a thickening stem and chokes it. Check growing plants weekly and add ties as they climb; a heavy truss of fruit can snap an unsupported branch in a storm.

Why bother, beyond tidiness

Support isn't cosmetic. Keeping foliage and fruit up off the soil dramatically cuts disease (soil-splash is how early blight and other problems reach the leaves), improves airflow, and makes pests like hornworms far easier to spot. A supported, pruned, mulched tomato is a healthy one. Get your transplant date right on the planting calendar.
