These square pond plant pots are designed specifically for aquatic planting, providing excellent stability and root support for marginal and deep-water plants. Available in a range of sizes to suit everything from compact marginals to larger specimen plants, they feature a mesh or slatted design that allows water to circulate freely around the roots while retaining your planting medium. Simply choose the size that suits your plant, fill with aquatic compost or pond soil, and place at the correct depth in your pond or water feature.
