6 Best Grafting Tapes for Success

You’ve made the perfect cuts, aligned the cambium on your rootstock and scion, and now everything hangs in the balance. The next two minutes of wrapping will determine whether that graft takes or fails. For a first-year grafter, choosing the right tape feels overwhelming, but it doesn’t have to be expensive or complicated. The right tape is simply the one that seals moisture, holds things together, and gets out of the way when its job is done.

Understanding Parafilm and Self-Sealing Tapes

Grafting tape isn’t just tape. True grafting films, like Parafilm, are self-sealing, waxy, and highly stretchable. Their magic lies in the stretch; pulling the film activates its clingy, waxy nature, allowing it to stick to itself and form a waterproof, breathable skin around the graft union.

This self-sealing quality is a game-changer for beginners. You don’t need to tie knots or worry about adhesives that can damage the tender bark. You simply stretch and wrap, and the film holds itself in place. The goal is to create a tiny greenhouse that locks in humidity around the cut surfaces, preventing the scion from drying out before the vascular tissues can fuse.

Unlike electrical tape or duct tape, which can girdle a tree and leave a sticky residue, grafting films are designed to expand with new growth or break down under sunlight. This "planned obsolescence" is a feature, not a flaw. It ensures the tape doesn’t strangle your successful graft a few months down the line.

Parafilm M: The Original Lab-Grade Grafting Film

Parafilm M is the classic choice, and for good reason. It was originally designed for sealing beakers and test tubes in a laboratory, which tells you everything you need to know about its ability to create an airtight, moisture-proof barrier. It is incredibly stretchy and soft, conforming perfectly to every nook and cranny of the graft union.

Its biggest strength is also its main weakness: it has very little structural integrity. Parafilm M is for sealing, not for binding. You can’t use it to pull a mismatched graft tightly together. For that reason, many grafters use it as the primary wrap to seal the scion and union, then add a rubber band or a stronger tape over it for mechanical strength.

Don’t let the price of a roll scare you off. A single roll of Parafilm M will last a hobbyist for hundreds, if not thousands, of grafts. You only need a small, two-to-three-inch piece, which you then stretch to double or triple its length. On a per-graft basis, it’s one of the most economical choices you can make. It degrades nicely in the sun, so you rarely have to come back and remove it.

Amtape Grafting Tape for Reliable, Budget Grafts

If Parafilm M is the lab standard, Amtape is the field workhorse. It was developed specifically for grafting and budding, and it strikes an excellent balance between stretch, seal, and price. It feels a bit more like a plastic film than the waxy Parafilm, but it performs its core function just as well.

Amtape often comes on a roll with perforations every few inches. This is a huge advantage for beginners and for anyone doing a lot of grafts at once. You don’t have to fumble with scissors or try to guess the right length; you just snap off a piece and get to wrapping. This simple feature saves time and reduces waste.

It provides a slightly stronger hold than Parafilm M, though still not enough for major structural support on its own. It effectively prevents moisture loss and is a fantastic, no-nonsense option for first-timers. It’s a reliable product that proves you don’t need to overthink your supplies to get high success rates.

Ounona Clear Tape: A Versatile, Low-Cost Choice

When you search for "grafting tape" on Amazon or eBay, you’ll find countless rolls of clear, non-adhesive polyethylene film, often under brand names like Ounona or other generic labels. This is your ultra-budget option. It’s essentially a specialized, stretchy plastic wrap that works surprisingly well.

This type of tape is waterproof and self-clinging when stretched, just like the name brands. It creates a solid seal and holds the union together with decent pressure. Because it’s clear, you can sometimes see the graft union beginning to callus, which is a nice bonus for an anxious first-timer.

The main tradeoff is its durability. Unlike Parafilm, this PE film is very slow to break down in the sun. You will likely need to remove it manually after the graft has fully taken to prevent it from girdling the branch. For a hobbyist with a manageable number of trees, this is a minor inconvenience in exchange for a very low upfront cost.

VViViD Bio-Graft: A Biodegradable Stretch Film

For those who prefer a "set it and forget it" approach, a biodegradable film is an excellent choice. VViViD’s Bio-Graft tape offers all the functionality of a standard grafting film—good stretch, a watertight seal—but is engineered to break down completely from UV light and moisture over a single season.

This eliminates the task of returning to your trees to cut away old tape. While this might seem like a small thing, it’s one less chore on your list. It also ensures you never accidentally forget a piece of tape that ends up strangling a thriving branch a year later.

The cost is typically a bit higher than standard films, but the convenience can be worth it. The breakdown rate can vary depending on your climate; it will disappear faster in a hot, sunny, and wet region than in a cool, dry one. It’s a smart investment if you value convenience and want to minimize your long-term impact in the orchard.

Scionon Grafting Tape for Secure, Watertight Seals

Sometimes you need more than just a moisture barrier. Scionon tape provides both a seal and significant structural support. It’s thicker, tougher, and has a more aggressive tack than Parafilm, allowing you to bind the graft union with firm, even pressure.

This is the tape you reach for when dealing with slightly larger scion wood, performing a T-bud, or grafting in a windy location where the new shoot might get whipped around. It has enough strength to often eliminate the need for a secondary binding like a rubber band or twine, simplifying the process.

While it’s a fantastic product, it’s also less forgiving. Because it’s stronger and more adhesive, you must be more diligent about removing it once the graft is healed. If left on, it will absolutely girdle the tree. Think of it as a specialized tool: perfect for when you need strength, but overkill for a simple whip-and-tongue on a pencil-thin shoot.

Buddy Tape: Perforated for Easy Application

Buddy Tape is the premium option, and many experienced grafters swear it’s the best material available. It is incredibly elastic, capable of stretching up to eight times its original length. This extreme stretch means a single roll lasts an incredibly long time, and you can wrap a graft union with very little material.

Like Amtape, it comes perforated, making it fast and easy to grab a uniform piece. It’s self-adhesive, breathable, and biodegradable. The thin film allows for excellent gas exchange while keeping moisture locked in, and it even allows buds to push directly through the tape, which is a remarkable feature.

The elephant in the room is the price; a roll of Buddy Tape is a significant upfront investment. However, when you calculate the cost per graft, it becomes much more reasonable due to the high stretch. For a beginner, its ease of use can reduce fumbling and failed wraps, potentially increasing success rates and making the investment worthwhile.

Proper Tape Application for High Graft Success

The best tape in the world will fail if applied incorrectly. The single most important rule is to stretch the film as you wrap. This action is what makes the tape cling to itself and creates the tight, waterproof seal necessary for success. A loose wrap is a failed wrap.

Start your wrap about a half-inch below the graft union. Wrap upwards, overlapping each layer by about 50%, like wrapping a hockey stick. Ensure you cross the cut lines multiple times, applying firm, consistent pressure. Continue wrapping at least a half-inch above the union. For extra security, many people wrap the entire scion, right up to and over the terminal bud, to prevent any moisture loss.

The goal is to create snug, uniform pressure without strangling the cambium layer. It should feel secure, with no gaps or loose ends. Remember, you are creating a sealed, humid environment where two separate pieces of wood can heal into one. Your wrapping technique is just as important as the quality of your cuts.

Ultimately, the best grafting tape is the one you have on hand that you know how to use. Whether you choose the lab-grade seal of Parafilm M, the budget-friendly utility of a generic clear tape, or the convenience of Buddy Tape, your success hinges on a clean cut and a tight wrap. Focus on your technique, and any of these tapes will help you turn two trees into one.
