Gardening as commonly practiced is better than not gardening. Feeding yourself from your backyard is a huge benefit of having a garden, whether you are growing in wide rows or in horse troughs full of MiracleGro potting soil.
Having a garden makes you less fragile. But it doesn’t take you to the level of Nassim Taleb’s “antifragility,” as expounded in his book Antifragile. Something that is “antifragile” does not just survive bouts of disorder, it grows and even thrives through them.
This is an antifragile gardening system:
Chopping and dropping some plants leads to better growth and the fertilization of others. Having a broad range of species means that pests are very little issue. A big windstorm coming through would open up light and make non-damaged portions grow even better. The “messiness” of the system and the many redundancies make it a very powerful way to garden that is not fragile like traditional gardening systems that require careful timing, weeding, external fertilization, etc.
