This plastic Red Tomato Tray is split down the middle so you can install it around the base of an established tomato plant. The red reflects light back up to the plant, increasing productivity. Four funnel-shaped holes allow water to be poured directly to the roots, and the stem of each plant is hugged snugly in the centre, so no weeds can emerge, but keeping daytime warmth in the soil for longer into the evening. Sold in packs of 3 trays each. The tray measures 30 x 30cm (12 x 12 inches).
