This kit contains everything you need to grow a set of three marginal plants on your patio. A large light-brown plastic frost-proof planter (dia. 40cm) contains three young Marginal pond plants. There is also a bag of top quality aquatic soil and decorative gravel to allow you to create an attractive display. Once your plants have been planted up simply top up with water as shown on the instructions. Your plants will thrive and create an interesting display. You also have the option to transplant your mature plants to the main pond once they have grown and perhaps start the planting process all over again!
