The English Composting Garden is a stacking, vertical composting planter. The circular exterior is designed with a brick-like texture to give it a classical, stone appearance. Each planter pod can hold about 5 gallons of flora thanks to its circular construction which beautifully showcases plants and vegetation on all sides. The pods can be stacked as desired (max 6 recommended) or may be used individually as planters around an area. The English Composting Garden features a hollowed fillable core that can hold additional soil, fertilizer, and compost. This is perfect for worm composting as they dramatically increase nutrient production when mixed with the compost, making plants thrive. With the pods stacked in a garden, worms can also penetrate the compost from the bottom, spreading nutrients to the plants in the tower and throughout the surrounding garden soil. The pods are constructed from a naturally inert and incredibly strong plastic that's weatherproof and nature proof. Several drain holes allow moisture to escape to avoid root rot. Made in the USA with several color options.
