Manage everything you plant organically.

Grow your garden for wildlife, as well as people.  This will encourage beneficial insects and predators.

Learn your bugs.  Some are good, some are bad.  Once you start to know the difference, knowing which ones to squish or remove becomes far easier.

Play to your garden’s strengths, by figuring out and utilizing its characteristics.

Make soil care a priority.

Make your own compost and leaf mold.  Cuts back on the amount of stuff you are sending to the dump, and helps the garden at the same time.

Reuse and recycle what you can, where you can.  The less we stick in landfills, the better.

Whenever you can, use organic seeds.

Take environmental impact into account when choosing materials for your landscaping.  Where it comes from and how it is collected is as important as what it is made of, in the grand scheme of things.

Collect rainwater, and reduce the need for watering by improving soil and choosing appropos plants.

Make local sourcing your first choice.

Use traditional methods where it makes sense to.

Science is your friend to.  Not all of what comes out of research is chemically based or inappropriate for organic gardening.

Stop using artificial fertilizers.

Give up bonfires.

Control weeds without using herbicides.

Avoid the use of pesticides and treated wood.

Say not to GMO.

Choose weird heirloom varieties to grow from time to time.  Diversity is good, and growing something threatened here and there is a way to assist with that.
