I started doing it when i found out that a lot of the big nurseries use a type of fabric pot when they grow out trees for planting. I have three lemons that were 6 inches when i bought them and now they are over 2 ft in just 2 years. I have grown plants side by side, one in a traditional pot and one in a fabric pot and the fabric potted plants seem to grow bigger faster but they do need watered more
