Ross Root Feeder Refills 36‑Count, 25-10-10 High-Nitrogen Cartridges for Deciduous Trees & Shrubs, Premeasured Mess-Free

These refills simplify seasonal tree and shrub feeding by delivering a 25‑10‑10 nutrient balance where plants absorb it best: at the roots while you water. Each cartridge is ready to use — no measuring, no mixing — and the 36‑pack supplies multiple treatments across spring, summer, and fall. The refills are formulated specifically for deciduous trees and shrubs, helping maintain leaf growth and overall vigor when used as part of routine landscape care.

How do these refills feed trees and shrubs more effectively?

The refills release nutrients directly into the root zone when used with a compatible Ross Root Feeder, letting water carry fertilizer where fine feeder roots can take it up. This targeted approach reduces nutrient loss on the soil surface and improves uptake efficiency compared with broadcast spreading.

• Direct root delivery via Ross Root Feeder
• Premeasured cartridges eliminate spillage and uneven application
• Water-activated release ensures nutrients reach feeder roots

What is the nutrient formula and when should I apply it?

The product carries a 25‑10‑10 analysis—higher in nitrogen to support leafy growth in deciduous species. Apply during active growth periods: early spring, mid‑season (summer), and again in early fall according to plant needs and local growing conditions.

• NPK ratio: 25% nitrogen, 10% phosphorus, 10% potassium
• Suggested application windows: spring, summer, fall
• Designed for deciduous trees and shrubs rather than evergreens or turf

How easy are these refills to use and store?

Each refill comes premeasured and ready to drop into the Ross Root Feeder — no measuring cups, no mixing with water or spreaders. The 36‑count box gives you multiple cartridges for routine maintenance, and the compact cartridges are simple to keep in a dry, cool place between seasons.

• Premeasured cartridges for fast, mess‑free use
• No mixing, measuring, or special tools required
• 36 cartridges per pack for multiple treatments or multiple plants

Will this work with different tree sizes and landscape setups?

Yes — because the refills feed at the root zone, they are suitable for a wide range of deciduous tree and shrub sizes when used as directed. Larger trees may need multiple feeder placements across the root zone for even distribution.

• Suitable for a variety of deciduous trees and shrubs
• Use multiple cartridges for larger or multi‑trunk specimens
• Compatible with landscape beds and isolated yard trees when paired with the Ross Root Feeder

Who is this for? Home gardeners, landscapers, and property managers who want a tidy, low‑effort way to provide consistent nutrients to deciduous trees and shrubs will appreciate Ross Root Feeder Refills. If you use a Ross Root Feeder and prefer targeted, water‑activated feeding without measuring or mixing, these premeasured 25‑10‑10 cartridges save time and reduce fertilizer waste. They’re especially helpful for routine seasonal care when you want predictable, mess‑free applications across multiple plants.
