Foaincore 6-Pack 15-Gallon Slow-Release Tree Watering Rings, Green PVC — 90×90 cm Deep-Root Drip Irrigation

Foaincore 6 Pcs 15-Gallon slow-release watering rings are round PVC drip bags that deliver water directly to tree and shrub roots for controlled, deep watering.

These green, heavy-duty watering rings (six per pack) measure approximately 90 x 90 cm and each holds up to 15 gallons (about 57 liters). Built from durable PVC with a protective film, the rings provide a slow, steady release of water to newly planted trees, shrubs and evergreens. With updated outlet fittings, each bag dispenses water over several hours so you can reduce frequent hand-watering while encouraging deeper root growth and better establishment.

How long will each Foaincore watering ring release water?

Each ring is designed to slowly dispense its 15-gallon capacity over about 4 to 6 hours, depending on soil type and outlet settings. That steady flow reduces runoff and promotes absorption at the root zone.

• 15 gallons (≈57 L) capacity per ring
• Typical drip period: 4–6 hours per fill
• Fill frequency: usually 1–2 times per week for established plantings

Will these rings work with different tree sizes and planting conditions?

The circular design and large diameter (90×90 cm) suit small to medium trees, newly planted specimens and grouped shrubs. You can place the ring around trunks or root collars; the adjustable outlet fittings help tailor flow to different soil textures and plant water needs.

• 90 x 90 cm footprint supports deep-root watering
• Works on clay, loam or sandy soils with flow adjustment
• Suitable for trees, shrubs, evergreens and transplant sites

How easy is installation and maintenance for these irrigation bags?

Installation is simple: lay the ring flat around the tree, open the top cap, insert the water hose or fill port, then secure the lid after filling. The PVC construction is tear- and UV-resistant, and occasional cleaning of the outlet keeps flow consistent season to season.

• Quick setup — no tools required
• Top lid for easy filling and nutrient addition
• Durable PVC resists wear and sun degradation

Can I add fertilizer or nutrients to the watering rings?

Yes — the convenient top opening allows you to add soluble nutrients or root stimulants directly into the reservoir for efficient delivery to the root zone. Use soluble formulas according to manufacturer guidance to avoid clogging the outlets.

• Top lid accepts liquid nutrient solutions
• Delivers amendments straight to root area
• Flush outlets periodically to prevent buildup

Who is this for: Foaincore 6-piece 15-gallon watering rings are ideal for landscapers, homeowners, nurseries and gardeners who need a low-effort way to establish young trees and shrubs. If you want to cut down on daily hand-watering, improve root development, or provide targeted irrigation during hot, dry spells, these reusable, heavy-duty PVC rings offer a practical, time-saving solution.
