Vigoroot Planters are ideal for small gardens, patios and balconies or for simply growing herbs and vegetables within easy reach of the kitchen. They will give abundant crops that are easy to care for and easy to harvest. At the end of the growing season they can be folded away and stored for the following year. All the planters come with reinforced handles and a handy growing guide. The magic of Vigoroot fabric comes from its ability to \'air-prune\' the roots of plants, dramatically changing their formation and their ability to sustain the plant in a limited volume of compost. It encourages more vigorous rooting, which enables the plants to absorb more nutrients. It prevents the roots from growing too long, and helps prevent plants from becoming pot-bound, which would normally limit the plants\' growth. This means that the plants can grow to a much larger size in a relatively small pot. The super strong root system also helps the plants to become more resistant to harsh weather, pests and diseases. Diameter 30cm (12\') Height 40cm (16\'). Helpful hint: Porous fabric + vigorous growth = thirsty plants! Gardeners need to remember to water plants regularly.
