Unique Bargains Plant Saucers Plastic Square Flower Drip Trays 10pcs Red 7"

What is this? Planter pots use drainage saucers to collect the excess water that drains from pots after watering. Also can be used to soak plants to promote germination. Are there any advantages of the product? The shallow plates prevent the water flow through the soil in the container and out the bottom drainage holes onto the planting shelf, table, flooring, carpet, decking, furniture, or patio slab. Conducive to plants to keep the soil moist. What should I notice? Standing water will promote excess soil moisture and cause plant roots to get bad. The dishes need to be drained after each watering.
