I use a bit of soapy water, sometimes with a dash of rubbing alcohol to get rid of any persistent pests like Squash Beetles, otherwise I rely on planting heirloom seeds that are already adapted to resist pests and plantings that deter pests. My garden is bordered with 600 garlic plants and a few dozen marigolds which helps to deter pests and I have a pond beside it which attracts frogs, toads and birds which feed on any bugs that come to dine on what's mine.

I only kill three things in the garden
Hornet nests
Yellow jacket nests
Japanese beetles
The first two I have a foaming agent for the nest
The japs I kill by hand.

RoundUp: cut-and-paint only, no broadcasting or spraying of any kind, to be painted on buckthorn, honeysuckle, etc stumps.

I live on sand, have made soil from mulch and compost which gives me a great base, but it lacks trace elements, so have to add them which I do in soluble form. Spray is the only solution I have found to citrus leaf miner, all other pests are controlled naturally, and we just don't plant things like cabbages as teh grubs and snails would have a field day.

I get in there and weed and go after the bigger bugs by hand. I have a huge compost heap-about 8x8 feet and about 2.5 feet high. My dogs help me with it-they're always digging in it. Saves me having to turn it. I will use some chemical fertilizer when I have to, but thats kinda rare, I usually make my own. College chem 121 wasn't a total waste I try to use natural pesticides when I can. BT is usually my go to.

Organic whenever possible. ♥ Food definitely.

I have a worm box in the pantry and a compost bin in the yard. I never use anyhtingicides.

Heirloom seeds and pesticide free...yep. (I do use essential oils and other plants to keep the uggy buggies away)
