Using Sea90 Fertilizer for Growing Garlic ??

The Power of Sea90 Fertilizer in Growing Hardneck Garlic:

Garlic, particularly the hardneck variety, is beloved for its robust flavor, hardiness in cold climates, and the delightful scapes it produces. However, growing hardneck garlic to its full potential requires more than just planting cloves and hoping for the best; it demands a keen understanding of soil health and nutrient availability. Enter Sea90 fertilizer, a marine-derived mineral supplement that promises to revolutionize the way we cultivate garlic by enhancing soil microbiology, unlocking bound nutrients, and boosting overall plant health. Let's dive into the science and explore how Sea90 can make your hardneck garlic thrive.

Understanding Sea90 Fertilizer

Sea90 is not your average fertilizer; it is a mineral-rich product harvested from sea water, specifically from ancient sea beds or evaporated sea salts. This product boasts over 90 minerals and trace elements, including essential nutrients like magnesium, potassium, and calcium, as well as a suite of micronutrients in ionic form, which are readily available for plant uptake. The comprehensive mineral profile of Sea90 mirrors the natural mineral composition of ocean water, providing a balanced nutritional supplement for plants.

Sea-90 Fertilizer taps into the ancient mineral wealth of the Sea of Cortez. Originally discovered by Dr. Maynard Murray,  it comes from unprocessed and unrefined deposits found in this marine environment, once nicknamed "The World's Aquarium" by Jacques Cousteau for its biodiversity.  The harvesting process is relatively simple and doesn't require a lot of energy. Sea-90 is essentially mined from the seabed,  ground into a powder, and then sized for different applications. This minimal processing helps preserve the natural balance of minerals and trace elements that Sea-90 boasts.  By focusing on natural resources and a low-impact harvesting method, Sea-90 offers a potential path to a more sustainable approach to fertilizer. Sea-90 is derived from seawater, which naturally contains a vast array of elements from the periodic table. The company claims it replicates the exact proportions of these elements found in seawater.

Technical information suggests it contains a balanced mix of macro-elements (sodium, potassium, calcium, magnesium) and trace elements (copper, chromium, zinc, manganese, etc.) but avoids specifying the exact number or type of trace elements.

The Role of Sea90 in Soil Health

  1. Feeding Soil Microbiology: Soil is a living ecosystem teeming with microorganisms, enzymes, and fungi, all of which play crucial roles in nutrient cycling and soil structure. The diverse minerals in Sea90 serve as a buffet for these soil organisms, enhancing microbial activity and diversity. These microbes decompose organic matter, release nutrients, and improve soil texture, creating a more productive soil matrix.

  2. Unlocking Locked Nutrients: Over time, soils can become compacted and nutrients can become chemically bound or "locked up," making them unavailable to plants. Sea90 contains elements that help break these chemical bonds, releasing nutrients into the soil solution where they can be taken up by plant roots. This is particularly beneficial in agricultural systems experiencing a decline in fertilizer efficiency, as it maximizes the utilization of existing soil nutrients.

  3. Improving Soil Structure: The mineral content in Sea90 also helps improve soil structure by promoting the formation of soil aggregates. Good soil structure enhances water infiltration, root penetration, and reduces erosion, creating an optimal growing environment for hardneck garlic.

Growing Hardneck Garlic with Sea90

Hardneck garlic, known for its hard central stalk and superior flavor, thrives in nutrient-rich, well-drained soils. Here’s how Sea90 can be integrated into the garlic-growing process to maximize yields and quality.

  1. Soil Preparation:

  • Soil Testing: Before planting, conduct a soil test to understand the nutrient status and pH of your soil. This will help you determine the appropriate amount of Sea90 to apply.

  • Application of Sea90: Incorporate Sea90 into the soil during the fall, a few weeks before planting your garlic cloves. A general recommendation is to apply 1-2 pounds of Sea90 per 100 square feet of garden space. This will ensure the soil is enriched with essential minerals as the garlic establishes its roots.

  1. Planting:

  • Planting Time: Hardneck garlic is typically planted in the fall, about 4-6 weeks before the ground freezes. This allows the cloves to develop roots while avoiding above-ground growth until spring.

  • Clove Preparation: Separate the garlic bulbs into individual cloves, leaving the papery husk intact. Plant each clove pointy side up, about 2 inches deep and 6-8 inches apart.

  1. Growing Season Care:

  • Fertilization: Throughout the growing season, a light application of Sea90 as a foliar spray or soil drench can provide additional nutrients. Mix 1 tablespoon of Sea90 in a gallon of water and apply every 2-4 weeks.

  • Watering: Ensure consistent moisture, especially during the bulb formation period in late spring. Avoid overwatering, as garlic prefers well-drained soil.

  1. Harvesting and Post-Harvest Care:

  • Scape Removal: In early summer, hardneck garlic produces flower stalks called scapes. Remove these scapes to direct the plant’s energy into bulb formation, and enjoy them in culinary dishes.

  • Harvest Timing: Garlic is ready to harvest when the lower leaves start to brown, typically in mid to late summer. Gently lift the bulbs from the soil and cure them in a well-ventilated area for several weeks.

Benefits of Using Sea90 for Hardneck Garlic

  1. Enhanced Flavor and Nutrient Density: The wide array of minerals in Sea90 contributes to the development of complex flavors and increased nutrient density in garlic bulbs, making them not only more delicious but also more nutritious.

  2. Increased Yield and Size: By improving soil health and unlocking essential nutrients, Sea90 can lead to larger and more plentiful garlic bulbs, ensuring a bountiful harvest.

  3. Disease Resistance: Healthy, mineral-rich soils can improve plant immunity, reducing the incidence of diseases and pests that often plague garlic crops.

  4. Sustainable Agriculture: Sea90 promotes sustainable farming practices by reducing the need for synthetic fertilizers and enhancing natural soil fertility.

Sea-90 Fertilizer, derived from mineral deposits near the Sea of Cortez, boasts a unique composition rich in trace elements and minerals. Proponents claim it can enhance soil health, improve plant nutrient uptake, and boost overall crop yield.  One particular advantage is that Sea-90 can be used in conjunction with existing fertilizer programs, potentially reducing reliance on synthetic inputs. Additionally, its organic certification makes it attractive to those seeking a more natural approach. However, some potential drawbacks exist.  Limited research exists to definitively prove its effectiveness across all soil types and plant varieties. Additionally, the long-term effects of consistent Sea-90 use on soil composition are still being explored.  Finally, while generally affordable, its cost can be higher than traditional fertilizers.


Unleash the inner alchemist in your soil with Sea-90 fertilizer! This volcanic rock dust masquerading as marine minerals offers a potent (and slightly salty) punch to enhance your hardneck garlic's journey from clove to colossal bulb.  Studies have shown that humic acids in Sea-90 can act like tiny Pac-Mans, gobbling up locked-away nutrients and making them readily available for your garlic to devour.  Think of it as a Michelin-starred meal for your microbes, leading to a thriving soil ecosystem that rivals the biodiversity of the Great Barrier Reef (well, maybe not that impressive, but you get the picture).

Some garlic growers suggests a potential 10-20% increase in garlic yield with Sea-90. That's like growing prize-winning bulbs without the back-breaking effort of a champion garlic wrestler (it's a real competition, look it up!).  So ditch the chemical concoctions and embrace the power of the sea! After all, who wouldn't want their garlic infused with the invigorating essence of the ocean breeze (minus the pesky seagulls, of course)?  Remember, happy soil, happy garlic, happy you! Now go forth and cultivate those monstrous cloves, because with Sea-90, the only tears you'll be shedding are from laughter (or maybe from chopping all that glorious garlic)
