Jobe's Organics Fruit & Citrus Fertilizer Spikes 160-Count — Slow-Release 8-11-11 NPK for Trees

Jobe’s Organics Fruit & Citrus Fertilizer Spikes are pre-measured, slow-release nutrient spikes designed to feed fruit, citrus, and nut trees with an 8-11-11 NPK formula for healthier growth and better yields.

These ready-to-use fertilizer spikes give trees a below-ground source of balanced nutrients without liquid runoff, sticky residues, or complicated mixing. Inserted around the tree’s dripline, each spike releases nutrients gradually where roots can absorb them. The 160-count pack is sized for regular seasonal feedings so you can maintain consistent nutrition across multiple trees or a few seasons.

How do these spikes feed my trees and when should I apply them?

The spikes dissolve slowly to deliver nitrogen, phosphorus, and potassium directly to the root zone, supporting both foliage and fruit development over time. For most fruit and citrus trees, apply spikes twice a year—early spring and late fall—to coincide with active growth cycles. You can add supplemental spikes during heavy fruiting seasons if needed.

• Slow-release formula reduces leaching compared to liquids
• Apply around the dripline where feeder roots are concentrated
• Recommended schedule: early spring and late fall; extra applications for heavy producers

How many spikes do I use per tree and how are they placed?

Dosage depends on trunk diameter and tree size; larger trees require more spikes spaced evenly around the dripline. Push spikes into the soil so they’re in contact with active roots; this ensures nutrients move into the root zone as spikes break down. The pack of 160 covers multiple trees or repeat seasonal treatments for several trees in a home landscape.

• Follow package guidance for trunk-calibrated counts
• Space spikes evenly around the dripline for uniform feeding
• Press spikes into soil; avoid placing on hard-packed surfaces

What’s in the formula and how does it avoid overfertilizing?

The 8-11-11 NPK ratio supplies balanced nutrients for growth (nitrogen), root and flower support (phosphorus), and fruit and overall plant vigor (potassium). Spikes are pre-measured to release nutrients gradually, lowering the risk of burning roots from a single heavy dose. This makes them a convenient option for gardeners who want controlled feeding without frequent measuring or mixing.

• 8-11-11 NPK tailored for fruit and citrus needs
• Pre-measured spikes eliminate guesswork and reduce over-application
• Slow-release action mitigates sudden nutrient spikes in soil

Are these spikes safe and easy to use around a home garden?

Yes—spikes are dry, compact, and simple to insert so they produce no messy runoff, fumes, or spills. Because nutrients are delivered underground, there’s less chance of attracting pets to strong smells or leaving visible residues on the surface. Still follow label instructions and keep spikes out of reach of children and pets until inserted.

• No mixing, no liquid spills, and minimal surface mess
• Designed to reduce runoff compared with soluble fertilizers
• Store sealed in original container and follow safety instructions

Who is this for? Home gardeners and small-property owners growing fruit, citrus, or nut trees who want a no-fuss, controlled feeding method will benefit from Jobe’s Organics fertilizer spikes. They’re particularly useful for people who prefer low-maintenance seasonal care, those who dislike handling granular or liquid fertilizers, and anyone seeking consistent root-zone nutrition without frequent applications. Professional landscapers who manage multiple trees can use the 160-count pack to streamline seasonal treatments across several specimens.
