SeedLaunch Pro™ Germination Maximizer + Starter Fertilizer 8-15-10

Yes! SeedLaunch Pro™ was designed to be applied at the time of seeding, but it can still help if your seed is already down or seedlings are starting to emerge. Apply it as soon as possible so the nutrients and germination enhancers can support early growth and establishment. Stick with your current watering schedule after applying.

SeedLaunch Pro™ was specifically designed to support new seed and early-stage root development—but it can also be used on existing lawns during overseeding.

Because it contains balanced nutrients, slow-release nitrogen, and soil-enhancing ingredients like frass and biochar, it can benefit established turf by improving soil health and encouraging thicker, more resilient growth. That said, if you're not seeding or overseeding, you may want to choose a fertilizer with a different nutrient profile tailored to mature turf.

Most big-box fertilizers are designed to cover large areas at a lower cost-per-bag. They typically use high amounts of quick-release nitrogen and apply at lower rates to stretch coverage. That approach makes sense for general-purpose feeding, but it’s not always ideal for new seed.

SeedLaunch Pro™ was built specifically for seeding projects. It’s applied at a higher rate because it includes more than just standard NPK. Ingredients like slow-release polymer-coated nitrogen, organic frass, biochar, and micronutrients are included to help create a better environment in the top layer of soil—where germination actually happens. The higher application rate reflects the work the formula is doing.

In short: it covers less because it’s doing more in every square foot.

Most general-purpose fertilizers are designed to feed established lawns and push top growth. SeedLaunch Pro™ is different—it’s built specifically for seeding projects.

It has a balanced NPK ratio (8-15-10) to support early root development, and includes targeted ingredients like slow-release nitrogen, organic frass, biochar, and micronutrients to improve the top layer of soil where germination happens.

It’s not about fast green-up—it’s about giving every seed the best chance to take hold.

Yes—when used as directed, SeedLaunch Pro™ is safe for children and pets. We recommend watering it in after application. This helps ensure the nutrients move into the soil where they belong, and avoids any contact with loose granules.

When used as directed, no—SeedLaunch Pro™ is formulated to minimize burn risk. It includes slow-release, polymer-coated nitrogen, which delivers nutrients gradually instead of all at once. That makes it much gentler than fertilizers with high levels of fast-release nitrogen.

As with any fertilizer, we recommend applying it evenly and watering it in after application. This helps move nutrients into the soil and keeps your lawn safe, especially during warm weather or dry conditions.

Not entirely. SeedLaunch Pro™ includes organic ingredients like frass and finely screened composted organic matter, but it also contains synthetic nutrients—including polymer-coated urea—for consistent, controlled feeding.

It’s a hybrid formulation, built for performance. The organic components help support soil biology and germination conditions, while the synthetic nutrients ensure reliable results during a critical stage of lawn establishment.

If you’re looking for a fully organic fertilizer, SeedLaunch Pro™ may not fit that category—but if you’re focused on germination success, it’s designed to give you the best of both worlds.

Because seedlings don’t need a nitrogen overload—they need balance. Many big-box fertilizers contain high levels of quick-release nitrogen. This can lead to a surge in top growth from existing grass, which often outpaces root development in new seedlings—crowding them out and blocking sunlight.

SeedLaunch Pro™ takes a more balanced approach. It includes premium, slow-release, polymer-coated nitrogen to deliver a steady, controlled feed—supporting healthy development without overwhelming young grass or existing turf.

Most big-box starter fertilizers rely on outdated assumptions that more phosphorus always equals better results. But research and modern turf practices show that excess phosphorus doesn’t necessarily improve results—and can create environmental runoff concerns.

SeedLaunch Pro™ uses a balanced 8-15-10 ratio, which delivers all the phosphorus new grass needs, without overdoing it. Combined with bioactive soil ingredients like frass, compost, and biochar, this smarter approach supports stronger root development while reducing waste.

Frass is a natural, nutrient-rich soil input made from insect compost—specifically from black soldier flies, which are widely considered the gold standard in frass production. These insects are raised on plant-based food scraps in tightly controlled environments, and the resulting material is dried and processed into a clean, odourless granule.

It contains organic matter, naturally balanced nutrients (NPK), and beneficial microbes that help improve soil biology. Frass represents leading-edge fertilizer technology, and its inclusion in SeedLaunch Pro™ is a performance-driven decision. It enhances microbial activity, supports early root development, and helps create better conditions for germination in the top layer of soil.

Despite being insect-derived, frass does not attract pests or introduce insects into your lawn—it’s fully processed, stable, and safe for use around people and pets.

CarbonCHARge™ is our proprietary biochar blend, engineered to support the top layer of soil where seeds germinate. It’s made from carbon-rich organic material that’s been superheated in a low-oxygen environment—a process called pyrolysis—which creates an ultra-porous structure.

This porous structure acts like a sponge in the soil, creating micro-sites that hold moisture and air around the seed zone. That helps reduce surface dry-outs, improve oxygen flow, and support the early-stage soil conditions germination depends on.

We include CarbonCHARge™ to help stabilize and enhance the critical top quarter inch of soil—the layer where your seeding project either takes off or stalls.

SeedLaunch Pro™ contains 8.0% total nitrogen. Of that, 4.3% comes from a premium polymer-coated urea that releases gradually over time to match the pace of seedling development. The remaining nitrogen comes from standard urea and monoammonium phosphate (MAP) to ensure adequate early seedling support. A small amount of nitrogen also comes from our organic frass component, which contributes to overall soil health and microbial activity.

Not at all—it depends on the context. Quick-release nitrogen is great for greening up established turf, but it can be too aggressive during seeding. SeedLaunch Pro™ uses a slower, more controlled nitrogen source to support young seedlings without overwhelming them. It’s not about “cheap vs. premium”—it’s about using the right tool for the job.

Yes! SeedLaunch Pro™ is designed to be applied at the same time as grass seed. In fact, that’s when it works best. It’s formulated to support germination and early root development from day one, so there’s no need to wait between applying your seed and your fertilizer.

Just spread the seed and fertilizer on the same day, then begin your watering schedule to keep the surface consistently moist.

SeedLaunch Pro™ can be left on the surface or incorporated into topdressing. Just spread it evenly and water it in after application to help the nutrients move into the soil where they’re needed.

If you’re applying it during a seeding project, you can spread it right before or after your grass seed. If you're covering your seeding area with something like peat moss, this can help hold everything in place and protect it from wind or washout.

Yes. For best results, we recommend watering SeedLaunch Pro™ in after application. This helps move the nutrients into the top layer of soil—right where new seeds are trying to germinate.

If you're applying it as part of a seeding project, you can water it in during your first post-seeding irrigation. Just be careful not to overdo it—avoid heavy watering that could wash away your seed. Stick to the same approach you'd use for germination: light, frequent watering to keep the surface consistently moist.

SeedLaunch Pro™ provides a steady source of nutrients designed to carry your lawn through the critical early stages of germination and establishment. In most cases, there’s no need to reapply for 4 to 6 weeks after your initial application.

After that, you can switch to a regular feeding schedule based on your lawn goals—whether that’s continued root development, top growth, or continued colour improvement.

No. SeedLaunch Pro™ does not contain iron, so there’s no risk of the rust-like stains commonly associated with some lawn fertilizers. That said, we still recommend sweeping or blowing any stray granules off hard surfaces after application—just to keep everything clean and where it belongs: on your lawn.

Each 4 kg (8.8 lb) bag of SeedLaunch Pro™ contains 0.70 lbs of nitrogen. At the recommended application rate of 2 kg per 93 m² (1,000 sq ft), you're applying approximately 0.35 lbs of nitrogen per 1,000 sq ft—a level that supports steady early growth without overwhelming young seedlings.

Yes, you can. While SeedLaunch Pro™ is optimized for use with grass seed, its balanced nutrients and soil-supporting ingredients can also benefit newly installed sod.

That said, most sod installations don’t need a starter fertilizer right away—especially if the sod was grown with fertilizer at the farm. If you do choose to apply, use a lighter rate and water it in well to avoid stressing the young root system.

For sod, think of SeedLaunch Pro™ as an optional boost—not a requirement.

No product can guarantee germination—whether it’s grass seed or fertilizer—and we don’t pretend to. SeedLaunch Pro™ is designed to support the conditions that lead to germination, especially in the top layer of soil where seeds need moisture, airflow, and microbial activity to take hold.

Germination still depends on how you prep your soil, spread your seed, and manage your watering. SeedLaunch Pro™ doesn’t replace that work—it helps you get more out of it.

If you’re following best practices, this formula creates a better environment for your seed to succeed.
