FoxFarm Happy Frog Citrus & Avocado Fertilizer — 4 lb Pack (2) Slow-Release Nitrogen, Calcium & Mycorrhizae

FoxFarm Happy Frog Citrus and Avocado Fertilizer is an OMRI-listed, slow-release nutrient formula designed to support healthy vegetative growth and root function in citrus and avocado trees.

Designed for home gardens and small orchards, this 4 lb pack (sold as a pack of 2) combines slow-release nitrogen with calcium, sulfur, and beneficial soil microbes to help trees develop robust foliage and stronger root systems. OMRI listing indicates suitability for organic production, and the inclusion of mycorrhizal fungi aims to improve root efficiency so trees can access water and nutrients more effectively over time.

How does this fertilizer support tree growth?

The formula delivers slow-release nitrogen to provide steady vegetative growth without the spikes that can stress plants. Added calcium and sulfur contribute to overall nutrient balance while supporting tissue strength and metabolic processes. Beneficial microbes, including mycorrhizae, are included to enhance root activity and nutrient uptake.

• Slow-release nitrogen for consistent leaf and shoot development
• Calcium and sulfur to support plant structure and nutrient balance
• Mycorrhizal fungi to increase root surface area and efficiency

When and how should I apply it to citrus and avocado trees?

Apply according to tree size and season: light, regular applications during the active growing season and reduced or no feeding during dormancy. Work granules into the soil surface under the canopy and water thoroughly to start the slow-release action. For new transplants, use smaller, more frequent doses until roots establish.

• Apply in spring and early summer for peak growth support
• Broadcast and lightly incorporate into the root zone, then water
• Adjust rate by tree age and trunk diameter per package directions

What benefit do the mycorrhizal fungi provide?

Mycorrhizal fungi form a symbiotic relationship with tree roots, extending the effective root surface area and improving access to water and immobile nutrients. This can lead to more efficient nutrient uptake, especially in challenging soils, and may help trees tolerate brief water stress better. Results depend on soil conditions and proper application.

• Expands root reach for better absorption of water and nutrients
• Supports establishment of young trees and recovery of stressed trees
• Works alongside slow-release nutrients for sustained feeding

Is this product suitable for organic gardening and all tree stages?

Yes; the OMRI listing means the formula meets organic standards for allowed inputs in organic production. The balanced composition and gentle slow-release action make it appropriate for newly planted saplings as well as mature citrus and avocado trees. Always follow label directions and adjust application based on tree age and soil tests.

• OMRI-listed for organic production compatibility
• Formulated for both new plantings and established trees
• Non-gaseous, granular form for easy, controlled application

Who is this for: Gardeners, hobby orchardists, and small-scale growers who want an organic-compatible fertilizer tailored to citrus and avocado trees will find this FoxFarm Happy Frog formula useful. It's especially helpful for those seeking a steady, low-maintenance nutrient release combined with beneficial microbes to support root health and improve long-term tree vigor. If you prefer granular, easy-to-apply products and are managing trees from planting through maturity, this pack-of-two provides ongoing feeding for multiple seasons.
