Give your trees room to grow with Vego Garden’s Tree Surround & Watering Ring Kit! Using a tree surround raises the plant, allowing you to easily control the soil that your tree will thrive in, as well as neatly contain mulch, and protect your tree from moisture loss, flooding, & damage from lawn equipment. Paired with the heavy-duty 16 gallon slow release watering ring, your trees will be set to thrive for years to come! Vego’s Tree watering bags are donut-shaped to easily fit around the trunk of your tree, and neatly into the Tree Surround. Placed under or over mulch, these UV-resistant watering bags provide slow-release irrigation to the roots of your tree, reducing shock and stress.
