Watering Rocks are a unique automatic drip system invented by JCPJ Enterprises LLC. They hold up to 5 gallons of water and require no electricity. Both lightweight (4lbs) and attractive they are an asset to any garden. During November and December I thought I would send out this blog to remind people that these rocks are self contained and can be used indoors to water a live or cut Christmas tree. Simply place the rock with as much water as you would like nearby the tree, elevated higher than the tree water receptacle, and run the included drip line to the tree. Adjust the included adjustable dripper to release the water as fast as you like. Simple as that.
