6 Best Clonex Rooting Gels For Tomato Cuttings For First-Year Success

You’ve found the perfect tomato plant—the one that produces flawless fruit and resists blight better than its neighbors. Instead of waiting a whole year to grow more from seed, you can simply take a cutting and create an identical clone. Using a quality rooting gel is the single most important step to ensure that cutting survives and thrives.

Why Use Rooting Gel for Tomato Cuttings?

You can stick a tomato sucker in a glass of water and get roots. It’s true. But what you can’t get is consistency, especially when you’re just starting out. Rooting gel isn’t just about speeding things up; it’s about dramatically increasing your success rate from, say, 50% to over 90%. That difference saves you time, frustration, and precious plant material.

A rooting gel performs two critical functions. First, it contains rooting hormones—usually Indole-3-butyric acid (IBA)—that signal the plant stem to stop producing leaf cells and start producing root cells. Second, the thick gel seals the fresh cut on the stem. This protective barrier prevents air embolisms and keeps fungal diseases, like damping-off, from entering the vulnerable wound. For a first-year grower, this built-in insurance policy is invaluable.

Think of it as the difference between a minor scrape healing on its own versus cleaning it and applying a medicated bandage. Both might heal, but one method is faster, cleaner, and far more likely to succeed without complications. For the small cost of a bottle of gel that will last for hundreds of cuttings, you guarantee a better outcome.

HydroDynamics Clonex: The Industry Standard Gel

When people talk about rooting gel, they’re often thinking of Clonex. Its distinctive purple gel is the benchmark against which all others are measured. It has a thick, tenacious consistency that clings to the stem exceptionally well, ensuring the active ingredients stay exactly where you need them during planting.

Clonex uses Indole-3-butyric acid (IBA), a reliable and well-studied synthetic plant hormone that consistently promotes vigorous root development. It also contains a blend of vitamins and mineral nutrients to nourish the young cutting as it begins to form roots. This isn’t just a rooting stimulant; it’s a complete kick-starter package for your new plant.

The main advantage of Clonex is its sheer reliability. It’s a proven formula that works exceptionally well for semi-hardwood cuttings like tomatoes. If you want a no-fuss, predictable product that delivers consistent results time and time again, Clonex is the go-to choice and a safe bet for any beginner.

Technaflora Rootech Gel for Vigorous Roots

If Clonex is the reliable standard, Rootech is its high-performance cousin. This gel is exceptionally thick—almost like a paste—which means it absolutely will not drip or run off the cutting. This is a significant advantage, as it guarantees the entire cut surface remains coated with hormones even when inserted into a wet growing medium.

Rootech Gel is formulated with a powerful concentration of IBA, which often results in an explosion of root initials. Where some gels might produce a few long roots, Rootech tends to encourage a dense mat of fibrous roots right at the base. This robust root ball helps the new clone establish itself much faster once transplanted into soil.

The tradeoff for this power is a slightly higher price point. However, a little goes a long way due to its thickness. Choose Rootech if your primary goal is the fastest possible development of a dense, healthy root system and you don’t mind spending a bit more for premium performance.

Olivia’s Cloning Gel: A Proven Organic Option

For the hobby farmer committed to organic practices, finding an effective rooting product can be a challenge. Olivia’s Cloning Gel fills that niche perfectly. It forgoes synthetic rooting hormones like IBA in favor of a proprietary formula derived from natural plant extracts and nutrients. It’s a different approach to the same problem.

Because it doesn’t rely on a concentrated synthetic hormone, the rooting process can sometimes be a day or two slower than with products like Clonex or Rootech. However, it is remarkably effective and gentle on the cuttings. Users often report healthy, natural-looking root growth without the sometimes-overwhelming explosion of roots seen with stronger hormone gels.

This is the ideal choice for anyone maintaining an organic garden or who prefers to avoid synthetic inputs. It’s also a great option for more delicate herbs and plants alongside your tomatoes. It proves you don’t need a lab-synthesized chemical to achieve excellent cloning success.

Quick Clone Gel: Fast Acting for Quick Results

The name says it all. Quick Clone Gel is engineered for speed, making it a fantastic tool for those moments of opportunity or crisis in the garden. Did a storm snap your favorite indeterminate tomato’s main stem? With a quick, clean cut and a dip in this gel, you can turn that disaster into a brand-new, productive plant in record time.

The formulation combines a rooting hormone with a blend of B vitamins and other growth promoters. This cocktail is designed to reduce the initial shock to the cutting and jump-start the cellular processes that lead to root formation. The gel itself is a bit thinner than some competitors, so be sure to get a good, even coat.

Consider Quick Clone Gel your emergency-response tool. While it’s perfectly suitable for planned cloning projects, its ability to deliver rapid results makes it uniquely valuable for salvaging broken branches or quickly multiplying a plant that you realize is performing exceptionally well mid-season.

MX Clone Gel with Added Vitamins and Hormones

MX Clone Gel takes a holistic approach to cloning. It understands that a cutting needs more than just a hormonal signal to grow roots; it also needs nourishment. This product is packed with a wide spectrum of vitamins, particularly B1, which is known to help plants manage stress and encourage new growth.

The gel provides the essential IBA hormone to initiate rooting, while the vitamin package supports the overall health of the cutting during this vulnerable period. This can lead to greener, healthier-looking clones that are less likely to wilt or yellow while they work on developing roots. The result is a smoother transition from a leafless stem to a fully-fledged, photosynthesizing plant.

This is a great all-around choice, especially for beginners. The added nutritional support provides a wider margin for error. If your humidity dome isn’t perfect or your light is a bit off, the vitamins in MX Clone Gel can help the cutting power through the stress and succeed anyway.

Hormex Rooting Gel: Trusted Name for Hobbyists

Hormex has been a trusted name in plant propagation for decades, long before gels became the standard. While they are famous for their rooting powders, their gel products carry that same legacy of reliability. They are a workhorse product often found in the sheds of seasoned gardeners.

One of the unique aspects of Hormex is that they offer their products in different numbered strengths. While tomatoes are generally easy to root and do well with a general-purpose gel, this concept is important. It reminds us that not all plants are the same. Hormex Rooting Gel #8 is typically the right strength for semi-hardwood cuttings like tomatoes.

Choosing Hormex is about trusting a long history of success. It’s a straightforward, no-frills product that does exactly what it promises. It’s an excellent choice for the hobbyist who wants a single, reliable product that can handle tomatoes one day and a harder-to-root woody shrub the next.

Best Application Technique for Tomato Cuttings

Your success with any rooting gel depends heavily on your technique. First, select a healthy, vigorous sucker or side shoot about 4-6 inches long. Use a sterile, sharp blade—not scissors, which can crush the stem’s vascular tissue—to make a clean 45-degree cut just below a leaf node. Carefully strip off the lower sets of leaves, leaving only the top two or three.

Next, and this is crucial, never dip your cuttings directly into the main product container. Doing so will contaminate the entire bottle with potential pathogens. Instead, pour a small amount of gel into a separate, clean dish or bottle cap. This small step preserves the integrity of your gel for future use.

Dip the bottom inch of the prepared cutting into the gel, ensuring the entire cut surface is coated. Immediately plant the cutting into a pre-moistened, sterile medium like perlite, vermiculite, or a seed-starting mix. To maintain high humidity, cover the pot with a clear plastic bag or a humidity dome. Place it in a warm spot with bright, indirect light, and you should see roots in 7-14 days.

Choosing the right rooting gel comes down to your priorities—organic principles, raw speed, or all-around reliability. Any of these six options will give you a massive advantage, turning one prized tomato plant into an entire row of perfect clones. This simple technique is one of the most powerful skills a hobby farmer can master.
