Fabric Mulch Rings (6-Pack)

Grow bags have one built-in flaw: the entire top surface is exposed soil, and sun plus wind pull water out of it faster than any other planter loses it. The fix growers have used for a century is mulch — but loose straw blows off a balcony and bark migrates. The Fabric Mulch Ring is mulch, engineered: a breathable woven ring that lies on the soil surface, slowing evaporation dramatically while still letting water and air pass down to the roots.

Each ring also does three quiet jobs at once. It blocks weed seeds landing on the bag top, it stops soil from splashing out during watering (and up onto lower leaves, which is how soil-borne disease spreads), and it tidies the bag so the balcony looks deliberate rather than improvised. Water in, weeds out, moisture in — the whole life of a ring is one season, then it composts or washes for reuse.

The set of six covers a standard balcony veg run: two 7-gallon bags, two 5-gallon pots and two wide planters. They are the natural companion to the Grow Bag Rescue Kit (which includes two) and the Water Catch Tray Set — the full system that makes fabric bags behave on a real balcony instead of a farm field.
