Garlic Fertilizer, Complete Liquid Garlic (8 oz)
TPS NUTRIENTS offers a complete liquid garlic formula designed to support thriving garlic and Allium varieties. It emphasizes bulb development and healthy growth, with easy-to-follow care instructions. This product is suitable for both established beds and containers, enabling regular feeding to sustain bulb size throughout the season.

Clear application guidelines help ensure balanced feeding without over-fertilizing.
Liquid Power Garlic Fertilizer
Gardenera’s Liquid Power Garlic Fertilizer is engineered for strong, flavorful bulbs. It supports vigorous root development, large clove formation, and pungent flavor across garlic varieties. The product provides a balanced NPK and a low pH to improve nutrient availability, which can be particularly beneficial in soil with locked micronutrients. Suitable for indoor and outdoor use, it emphasizes rapid nutrient delivery through the foliage and root zone.
True Organic Blood Meal
True Organic Blood Meal provides a high-nitrogen organic source ideal for vegetative growth in heavy feeders like garlic early in the season. While not a complete fertilizer, it can complement other products by boosting leaf growth and overall plant vigor. It’s suitable for both in-ground and container setups, and can be applied during spring and fall for ongoing nutrition.
Onion Fertilizer For Alliums
TPS NUTRIENTS’ Onion Fertilizer is formulated to promote large bulbs and vigorous leaf growth for onions and alliums, including garlic. With a liquid formula for easy absorption, it supports improved nutrient uptake and flavor. This option can be a practical addition to a garlic-focused feeding plan, particularly when used in combination with a nitrogen-rich base.
Wicked Growth Garlic + Onion Fertilizer
Old Cobblers Farm’s Wicked Growth Garlic + Onion Fertilizer emphasizes root nourishment, flavor enhancement, and robust growth with eco-friendly slow-release nutrients. Available in different package sizes, it’s designed to sustain long-season feeding. This product supports solid root systems and healthier tops, contributing to larger and tastier bulbs when used as part of a balanced feeding strategy.
Buying Guide: Key Purchase Considerations
When selecting a garlic fertilizer, consider these factors to maximize bulb size, flavor, and plant health:
- Form and ease of use: Liquid formulas provide quick uptake and easy adjustable feeding, while granular and slow-release options reduce application frequency.
- NPK balance: Garlic benefits from balanced nitrogen for leaf growth early in the season, with phosphorus aiding root and bulb development and potassium strengthening bulb structure and flavor.
- Organic vs synthetic: Organic sources like blood meal support sustainability and soil biology but may work more slowly; synthetic/liquid options offer precise, fast-acting nutrition.
- Soil and climate: In sandy or drought-prone soils, higher potassium may improve bulb quality; in cooler climates, ensure early-season nitrogen supports green growth without delaying bulbing.
- Allium compatibility: If you grow multiple Allium crops, choose products labeled for garlic, onions, and shallots to streamline feeding.
- Application schedule: Follow product-specific guidance to align feeding with garlic growth stages—greens in spring, bulb formation in late spring to early summer, and post-harvest soil health.
Overall, a mixed approach often yields the best results: a base liquid or granular fertilizer with a nitrogen boost during vegetative growth, followed by phosphorus- and potassium-focused nutrients as bulbs begin to form. Always start with a soil test when possible to tailor your fertilizer plan to your garden’s specific needs, improving bulb size, flavor, and storage quality over multiple seasons.
