When looking to grow tomatoes, you might wonder which grow bags or pots you should be going for. Experiments have shown that growing plants such as tomatoes in fabric grow bags are healthier compared to those that are grown in plastic pots and the reason is not the location, because they have both been in the same view. It's not the weather either as they both had the same chances.
It was observed that the one in plastic pot was overcrowded, the roots in the plastic pot were circulating around and around and around. Eventually, if disease didn't kill it already, it would just choke itself to death. So the roots finally find something they can't find in the fabric pot. What happens is, the roots try the circle. What they do is, they're self pruned.
When they hit the sidewalls, this self prunes so the roots lay beautiful and that's why the plants are much healthier. It is recommended that if you do not have any space, you do not want a guide and dig up the ground, that you go with a fabric grow bag.
They are not too expensive. You can buy some of the best quality fabric tomato grow bags which you could use to grow tomatoes online and they are not expensive. A decent quality fabric grow bag would normally cost between $20 to $30.
