Haxnicks Vigoroot hanging basket liner to get full enjoyment of flowers – more abundant and longer lasting blooms! It is made with unique “Vigoroot” an advanced air-pruning fabric that creates a super-strong root system for healthier more productive plants. When the roots reach the side of the Vigoroot fabric the air pruning process takes place enabling roots to continue to develop without rootballing. The strengthened root system can take on more nutrients benefitting the entire plant. Liner can be washed at the end of the season and reused year after year. For optimal results pair the Vigoroot liner with the Aquastore water retention liner sold separately #50-9820.
