Caulimo Deep Root Watering Tool for Trees, 32" Stainless Steel Spike with Brass Valve & T-Handle, Fertilizer Bottle

This long, welded stainless-steel spike combines a sharp point, 4-side outlet design, and a brass shut-off valve to push water and nutrients below compacted soil surfaces. Included is a small fertilizer bottle for precise, diluted feeding; the tool also aerates the soil as it penetrates, reducing surface runoff and evaporation. Whether you want targeted irrigation during dry spells or a way to supplement feeding at the roots, this tool makes deep watering straightforward and efficient.

How does the Caulimo spike get water and nutrients where roots can use them?

The spike's 32-inch length places water lower in the soil profile where active roots absorb moisture and fertilizer. Four side outlets disperse flow sideways to avoid channeling and to wet a wider root zone. A brass valve with a standard 3/4" garden hose thread lets you control flow or attach a hose for direct pressurized watering.

• 32" stainless-steel shaft reaches below soil surface to root depth.
• Four side holes spread water outward, reducing clogging.
• Brass shut-off valve and 3/4" GHT connection for hose compatibility.
• Non-slip T-handle for controlled insertion and removal.

Can I use fertilizers with this root feeder, and how?

The tool includes a 3.5 oz fertilizer bottle that screws into the spike so you can apply diluted liquid feed directly into the root area. Mix fertilizer according to the product label, pour into the bottle, and allow the solution to flow into the soil or use the valve to regulate slow release. This targeted approach helps reduce wastage and keeps nutrient delivery concentrated where roots can access it.

• Use diluted liquid fertilizers as directed on the label.
• Insert bottle into the spike for direct root delivery.
• Adjust valve to control dispensing rate and avoid overfeeding.
• Pair with periodic watering for even distribution of nutrients.

Is the spike durable and easy to use in compacted or dry soils?

The spike is constructed from stainless steel with welded seams and a polished finish to resist rust during outdoor use. The sharp tip and robust T-handle provide leverage for driving the tool into firm or compacted ground; in very hard soils, pre-wetting or loosening the soil can simplify insertion. After use, rinse and store in a dry place to preserve the finish.

• Stainless-steel construction resists corrosion for long-term use.
• Sharp point and rubber T-handle for secure, easy insertion.
• Welded build and brass valve for reliable performance.
• Rinse after use to prevent mineral buildup on holes and valve.

How does this tool help conserve water compared with surface watering?

By delivering water beneath the soil surface, the spike cuts down on evaporation and runoff, directing moisture straight to root zones where plants need it most. The side outlets distribute flow laterally, improving soil wetting efficiency and reducing the number of hose-on sessions required. This makes it an effective option during dry periods or for drought-conscious irrigation routines.

• Deep delivery minimizes surface evaporation losses.
• Side outlets reduce concentrated surface flow and runoff.
• Precise application limits wasted water on non-root areas.
• Good for targeted watering during drought or restricted use.

Who is this for? Home gardeners, orchard managers, and landscapers who need a durable, simple tool for deep root watering and targeted feeding will find this spike useful. It suits established trees, shrubs, and fruiting plants where surface watering is inefficient or when you want to supplement root nutrition. If you manage compacted soils, live in dry climates, or prefer efficient, low-waste irrigation for larger plants, the Caulimo Deep Root Watering Tool is designed for those needs.
