6 Best Tomato Twine For Supporting Plants That Old Gardeners Swear By
Discover the 6 tomato twines seasoned gardeners trust. From biodegradable jute to durable synthetics, learn which options provide the best support for a heavy harvest.
You walk out to your garden one July morning and see it: a heavy-laden tomato branch, bent at a sharp angle, nearly snapped from the weight of its own fruit. It’s a gut-wrenching sight for any gardener who has spent months nurturing that plant. This is why the simple, often-overlooked choice of tomato twine is more than just a detail—it’s cheap insurance for your harvest.

Why Old-Timers Are Picky About Tomato Twine
Experienced gardeners don’t just grab any old string. They know that the wrong twine can cause more problems than it solves, from snapping under pressure to strangling the very plants it’s meant to support. The ideal twine is a careful balance of strength, texture, and longevity.
The core conflict is between natural and synthetic materials. Natural fibers like jute or sisal are biodegradable and have a rough texture that grips stakes well, but they can rot in a wet season, failing when you need them most. Synthetics like polypropylene last forever and won’t break, but they can slice into tender stems if you’re not careful and must be meticulously removed at the end of the year to avoid polluting your soil.
Think of it this way: are you growing heavy, indeterminate heirlooms that will climb for months, or compact determinate varieties that set their fruit all at once? Are you in a dry climate where jute will last, or a humid one where rot is a constant battle? Your answer dictates which twine is a tool and which is a liability.
T.W. Evans Jute: The Biodegradable Classic
Jute is the quintessential garden twine for a reason. It’s soft enough that it’s less likely to damage tender green stems, and its fibrous texture provides excellent grip on stakes and trellises. When you tie a knot with jute, it tends to stay put.
This 600-foot jute twine is perfect for crafting, gardening, and gift wrapping. Made from natural jute fibers, it's strong, biodegradable, and easy to use for various DIY projects.
Its greatest strength is also its weakness: it’s fully biodegradable. At the end of the season, you can simply snip the vines and toss the whole lot—twine and all—into the compost pile. This convenience is a huge time-saver during fall cleanup.
However, that biodegradability means it has a limited lifespan. In a particularly rainy or humid summer, jute twine can weaken and rot mid-season, potentially snapping just as your tomatoes are at their heaviest. It’s a fantastic choice for lighter determinate varieties or for gardeners in arid climates, but it might not be robust enough for a season-long battle with heavy, sprawling Brandywines in the damp Northeast.
Tytan Sisal Twine for Heavy Tomato Loads
When jute just won’t cut it, sisal is the next step up in the natural fiber world. Derived from the agave plant, sisal is noticeably stronger and more durable than jute. It’s the twine you reach for when you’re staking massive Beefsteak or Cherokee Purple plants that produce pounds of fruit on a single truss.
This added strength comes with a tradeoff. Sisal is rougher and stiffer than jute, so you have to be more mindful when tying it. If cinched too tightly, it can absolutely girdle a stem, restricting the flow of water and nutrients. Always use a loose figure-eight loop to give the plant room to grow.
Despite its toughness, sisal is still a natural fiber and will eventually break down in the compost. It just takes a bit longer than jute. Think of it as the heavy-duty, biodegradable option for serious tomato growers who need reliability without turning to plastics.
Norpro Polypropylene Twine: Weatherproof Pick
Sometimes, practicality has to win out. Polypropylene twine is the go-to for gardeners who need absolute, season-long reliability, no matter the weather. This stuff is completely waterproof, will not rot, and has a tensile strength that can handle the heaviest tomato clusters without a hint of strain.
This durability makes it highly reusable. At the end of the season, you can collect the ties, wash them, and store them for next year, making it an economical choice over time. It’s especially valuable in very wet, humid climates where natural twines are guaranteed to fail before the first frost.
The downside is purely environmental. Polypropylene doesn’t break down. Ever. You must be diligent about removing every last piece from the garden, or you’ll be finding bits of plastic in your soil for years to come. For those prioritizing a zero-waste garden, this is a non-starter, but for pure performance, it’s hard to beat.
Hemptique Hemp Cord: A Rot-Resistant Option
Hemp cord sits in a sweet spot between jute and synthetics. It’s a natural fiber, but it’s significantly stronger and more resistant to mold and rot than jute. This makes it an excellent choice for gardeners who want to stick with biodegradable materials but need something that can withstand a damp, demanding growing season.
Hemp is strong enough for most indeterminate varieties while still being relatively soft on the stems. It holds knots well and has a durable feel that inspires confidence. It will break down in the compost pile, though it takes a bit longer than standard jute.
The main consideration with hemp is often the cost. It tends to be more expensive than jute or basic polypropylene twine. However, for gardeners growing a few prized heirloom plants, the extra expense for a reliable, rot-resistant, and natural material can be a worthwhile investment in harvest security.
VELCRO Brand Garden Ties for Gentle Support
For those who cringe at the thought of cinching any kind of string around their plants, Velcro-style garden ties are a modern solution. These are wide, soft, and infinitely adjustable. You simply wrap the fuzzy strip around the stem and the stake and press it together.
The key benefit here is the lack of pressure points. Because the tie is wide, it distributes the load and is almost incapable of girdling a stem. This makes it perfect for supporting delicate main stems or attaching vines to a trellis without causing damage. They are also completely reusable for many seasons.
Of course, they are a synthetic product made of nylon and plastic, so they won’t break down. They also represent a higher upfront cost compared to a simple ball of twine. But for protecting a particularly valuable plant or for anyone who wants a foolproof, gentle support system, they are an outstanding tool.
Luster Leaf Twist-Ties for Quick Adjustments
Twist-ties are all about speed and convenience. These paper or plastic-coated wires are perfect for making quick, temporary adjustments in the garden. When you see a small side-shoot that needs to be guided onto the trellis, a twist-tie gets the job done in seconds.
Their main advantage is their ease of use. No knots required—just a simple twist. This makes it easy to loosen and readjust them as the plant grows, which is a frequent necessity with fast-growing indeterminate tomatoes.
However, they are not meant for heavy-duty support. The thin wire inside can easily cut into a stem if wrapped too tightly or if the branch becomes too heavy. They are best used for light-duty tasks, like training young vines or supporting small fruit clusters, rather than securing the main, load-bearing stalks of your plants.
Tying Methods to Avoid Damaging Your Plants
The best twine in the world is useless if your tying technique harms the plant. The number one rule is to never tie a tight loop directly around the plant stem. As the stem thickens, the twine will constrict it, a process called girdling that cuts off nutrient flow and can kill the branch or the entire plant.
The gold standard is the figure-eight loop. Make a loose loop around the stake or trellis, cross the twine over itself, and then make a second, larger loop around the plant stem. This creates a soft cradle for the stem that allows it to move and grow without being choked. The stake, not the plant, takes the strain of the knot.
Always tie to the main, sturdy stems, not the more fragile suckers or fruit-bearing trusses. Give the plant some slack; the tie should guide the plant, not immobilize it. Check your ties every couple of weeks, especially during periods of rapid growth, and loosen any that appear to be getting tight.
Ultimately, your choice of tomato twine comes down to your personal gardening philosophy—balancing convenience, cost, plant health, and environmental impact. There is no single "best" option, only the best option for your garden, your climate, and the specific tomatoes you’re growing. The most important thing is to walk your rows regularly, check your ties, and make sure your plants have the support they need to deliver that perfect summer harvest.
