Tomato plants are heavy feeders and fast growers, which means they often collapse under their own weight without proper support. Left untied, vines sprawl on the ground, making fruit more vulnerable to pests, disease and rot. Supporting and tying tomatoes improves yield, increases airflow and helps keep fruit clean and healthy.
There are several reliable ways to keep tomato plants upright, from single stakes and cages to trellis systems and the Florida weave. While the setup varies, one step is always the same: fastening the plant securely as it grows. The material you use for tying plays a big role in plant health. Twine that’s too thin, too tight, or made from synthetic fibers can damage stems and leave behind waste. Natural hemp and linen twines, on the other hand, provide strength, flexibility and biodegradability, making them ideal for both small gardens and commercial farms.

Why Tomato Plants Need Support
Tomatoes are vigorous growers. Without support, plants bend or break under the weight of their fruit. Stems lying on the ground are more likely to rot or develop blight and harvesting becomes more difficult.
- Airflow – Keeping vines upright improves circulation and reduces disease risk.
- Fruit quality – Tied plants hold clusters off the ground, making fruit cleaner and less prone to rot.
- Higher yields – Well-supported plants put more energy into producing fruit instead of recovering from damage.
- Ease of harvest – Vertical growth keeps plants accessible and manageable.
Both determinate and indeterminate varieties benefit from tying, but indeterminate plants, which continue growing all season, require regular, ongoing support.
Tying vs. Staking vs. Other Methods
Tying tomatoes is the act of fastening plants to a support. Staking is the broader method of using a post or pole to guide growth, while cages and trellises are alternative structures.
- Staking – A single stake driven into the ground near each plant. Requires regular tying as plants climb.
- Cages – Wire or metal enclosures that support stems without much tying. Easier for small gardens, less effective for vigorous indeterminate varieties.
- Florida Weave – Twine woven between posts along a row, holding multiple plants upright. Efficient for CSA programs and farms.
- Trellises/Netting – Larger structures that allow plants to climb, offering maximum airflow and yield potential.
No matter the system, tying remains the crucial step that keeps plants upright, healthy and productive.
Best Twine for Tying Tomato Plants: Why Choose Hemptique
The material you use to tie tomato plants affects both plant health and long-term sustainability. Plastic ties and wire can cut into stems, and synthetic options leave behind waste that lingers in the soil. Natural hemp and linen twines provide the right balance of strength and flexibility, holding plants securely while allowing for growth and airflow. When the season ends, they can be composted or disposed of without adding plastic to the environment.
Hemptique supplies a full range of biodegradable hemp and linen twines designed for agriculture and farm use from single stakes in a backyard garden to large-scale greenhouse and CSA operations. Explore our complete collection on the Farm & Agriculture Applications page.
Step-by-Step: How to Tie Tomato Plants with Twine
Supporting tomato plants properly means fastening them as they grow, not just installing a stake or cage and leaving them. Below is a practical step-by-step approach that works for both home gardens and larger farm rows.
Materials You’ll Need
Stakes, trellis, or support posts
Natural hemp or linen twine
Scissors or pruning shears
Gardening gloves
Step 1: Install the Support
Drive stakes 8–12 inches into the ground near each plant or set up a trellis or Florida weave system for multiple rows. For spacing, plan about 18–24 inches between plants to allow airflow and access for tying.
Step 2: Cut a Length of Twine
Cut a piece of twine long enough to loop around the plant stem and secure it to the stake or trellis with room for growth.
Step 3: Tie Using a Loose Loop
Wrap the twine around the stem just above a leaf node. Tie it to the support using a figure-eight loop, one loop around the plant, one loop around the stake to prevent rubbing.
Step 4: Adjust as the Plant Grows
As plants climb, add new ties every 6–8 inches of vertical growth. Check weekly to ensure ties aren’t too tight and shift them upward as needed.
Alternative Tying Methods
- Slip Knot – A quick loop that can be loosened and moved higher as the plant grows, saving time compared to cutting new twine.
- Florida Weave Tie – Twine is woven between stakes along a row, with plants tucked between the lines. A labor saver for larger plantings.
Variety-Specific Considerations
- Determinate tomatoes usually need fewer ties, since they stop growing at a set height.
- Indeterminate tomatoes continue to grow all season and require regular reties with stronger twine or trellis systems.
Comparison of Tomato Support Methods
There’s no single “best” way to support tomato plants. The right method depends on your setup, plant type, and whether you’re growing a few plants in the garden or managing long rows on a farm. Below is a side-by-side look at the most common support systems.
| Method | Pros | Cons | Best Use Case |
|---|---|---|---|
| Single Stake | Simple, inexpensive, space-efficient | Needs frequent re-tying; less stable for tall indeterminate tomatoes | Small gardens; determinate varieties |
| Florida Weave | Efficient for rows; strong support; reusable posts | Labor intensive; posts must be sturdy; needs regular tightening | Larger gardens, farms, CSA rows |
| Cages | Low maintenance once installed; good airflow | Bulky; harder to scale; limited for vigorous indeterminate types | Home gardens; a few plants at a time |
| Trellis/Arches | Maximizes airflow; high yield potential; easy harvest | Higher setup cost; more planning required | Commercial farms; indeterminate tomatoes |
Which Method Should You Choose?
Small gardens - a single stake or cage is usually enough.
CSA programs or farms - Florida weave saves time across long rows.
Indeterminate varieties - trellises or arches provide season-long strength.
Choose the support that fits your space and variety; the constant is fastening plants as they grow with a gentle, durable twine.
Mistakes to Avoid When Tying Tomato Plants
Even experienced growers run into problems if ties are done incorrectly. Avoiding these common mistakes will keep plants healthy and productive through the season.
Tying Too Tight
Fastening twine snugly around the stem can restrict growth and cut into plant tissue. Always leave a little slack so stems can expand naturally.
Using the Wrong Material
Wire, plastic ties or rough string can bruise or snap stems. They also leave behind waste. Choose a soft, flexible, biodegradable twine such as hemp or linen.
Waiting Too Long to Tie
Plants that are already sprawling on the ground are harder to secure without damaging branches. Begin tying when plants are about 10–12 inches tall.
Ignoring Growth
Tomatoes grow quickly, and ties that were fine one week may be too tight the next. Check and adjust ties weekly during peak growth.
Overcrowding Plants
If plants are spaced too closely, airflow suffers even with good tying. Allow at least 18–24 inches between plants to minimize disease risk.
Pro Tips for Tying Tomato Plants
Small adjustments in your tying routine can make a big difference in plant health and harvest results. These are practical tips growers use in both gardens and farm rows.
Start Early and Stay Consistent
Begin tying when plants reach 10–12 inches tall. Add new ties every 6–8 inches of vertical growth to keep stems upright and manageable.
Prune Before You Tie
Remove suckers or side shoots before tying. A cleaner stem reduces stress on the plant and improves airflow.
Use the Figure-Eight Method
Instead of a straight loop, cross the twine between the plant and stake. This prevents rubbing and gives the stem more breathing room.
Tie on Dry Days
Tying when stems are wet increases the risk of snapping brittle branches. Work in dry conditions for better flexibility.
Match the Twine to the Task
Thin twine works for small plants or seedlings, but heavier cord is better for indeterminate varieties or long rows tied with the Florida weave.
Think Ahead for Harvest
Plan your ties so fruit clusters hang freely. Proper spacing now makes picking easier later.
Conclusion: Healthy Tomatoes Start with Proper Ties
Supporting tomato plants the right way prevents breakage, keeps fruit off the ground and improves airflow for a healthier harvest. From single stakes and cages to the Florida weave and trellis systems, the most important step is fastening stems with the right material and adjusting ties as plants grow.
Natural hemp and linen twines provide growers with strength, flexibility, and sustainability in one solution. They hold firmly without cutting into stems and break down safely at the end of the season.

Frequently Asked Questions About Tying Tomato Plants
Do tomatoes need to be tied up?
What is the best way to tie tomato plants?
The figure-eight method with soft, biodegradable twine is the most reliable. It holds plants firmly while preventing stems from rubbing against stakes.
When should I start tying tomato plants?
Begin tying when plants are about 10–12 inches tall. Starting early prevents damage and helps direct growth upward from the start.
How often should tomato plants be tied?
Check plants weekly during peak growth. Add a new tie every 6–8 inches of vertical growth, and adjust older ties if they become tight.
What kind of twine is best for tomato plants?
Natural hemp or linen twine is best. They’re strong, flexible, and compostable, unlike plastic ties or wire which can damage stems and create waste.
Can you use string to tie tomato plants?
Yes, but not all string is suitable. Thin or synthetic string may cut into stems. Choose a natural fiber twine that has some give and is gentle on plants.
Should determinate and indeterminate tomatoes be tied differently?
Yes. Determinate varieties need minimal tying since they stop growing at a set height. Indeterminate varieties require regular tying throughout the season.
How do you keep tomato plants from falling over?
Use sturdy stakes, cages, or trellises combined with regular tying. Indeterminate varieties often need stronger support like a Florida weave or tall trellis.
Can I reuse twine from one season to the next?
It’s not recommended. Natural twine can weaken after a season outdoors. For the best support, start each season with new twine.
Can twine spread disease between tomato plants?
Yes, if the same twine is reused between infected and healthy plants. Always start with clean, new twine each season to avoid transferring pathogens.
How high should I tie tomato plants?
Keep tying as the plant grows, usually up to 5–6 feet for indeterminate varieties. Stop when the top of the support is reached, then pinch or prune to control height.
Can I use biodegradable twine in wet or humid conditions?
Yes. Hemp and linen twines hold their strength even when damp, unlike some natural jutes that weaken quickly. This makes them dependable for greenhouse and outdoor farms.
Is it better to tie tomatoes to stakes or cages?
It depends on scale and variety. Stakes and twine are efficient for rows of indeterminate tomatoes, while cages are practical for determinate types in small gardens.
What happens if tomato plants are tied too loosely?
If ties are too loose, stems can slip and break in wind or under the weight of fruit. A proper tie should be snug enough to support, but never constrict growth.
