5. Oh please don't get me started on fabric grow bags...

We’ll be here for a bit.
Totally reusable, I’ve been using some of the bags for years. They come in all the comparable sizes as plastic pots, but much, much better for the root system. The bags ‘air prune’ the roots as opposed to plastic pots where the roots spiral around the pot.

Air pruning is very different, the roots searching for food hit the sides of the bag and stop not spiral. This is caused by the soil around the bag side is slightly drier than toward the center. Being a fabric the outside of the bag dries the roots hit this ‘barrier’ and split into more and more branches of roots, letting those roots to get more nutrients…more roots…more yield. With fabric bags it’s almost impossible to get a root bound plant.

I will caution though…there are some really cheap bags out there. In the picture you can see the big bags are a little floppy. The smaller 10 gallon bags have additional stitching around the top edge for better support.

I get most of our bags online. We stocked up before tariffs China was a big supplier.
