Alas, I grow trees, and the fabric pots only lasted about 3 years. Having to repot a tree into a 20 gallon pot almost killed me. The other problem was that the fabric pots had a totally different watering schedule (more frequent) than the plastic pots, so if I didn't keep an eye on the ones in the fabric pots they drooped badly.
Same with making my own potting soil. Did it for several years, and I have discovered that as me and my bones get older, it is wisest to choose my battles, and mixing potting is not one of them.
On the other hand, the fabric pots ARE great for veggies! Even did corn in them once!
