Recently came across a great quote in The Interview section of Maclean's August 22, 2016 magazine.  Alison Gopnik said: What it really means to be a good gardener is to work hard to produce an ecosystem that will have enough diversity, enough possibilities, so it's robust, and it's resilient, and it can change when the seasons change.

A much better writer than me of course, Alison is referring to her book about parenting called The Gardener and the Carpenter.  However, it sounds like she knows a thing or two about organic gardening. 

Growing plants that suit your garden, that you enjoy, that provide food and shelter for both good bugs and birds also creates a garden that will usually look good or provide food.  Furthermore, caring for the soil by using compost and mulch will do a lot of your weeding, fertilizing, watering and tilling for you.  Healthy soil ecosystems feed plants naturally. 

Providing a shallow dish of water and some abiotic elements, such as rocks or dead stumps further enhances the livability of your garden for beneficial bugs like earthworms and flying insects.
