Typical urban soils are deprived of much of this crucial microbial life due to a number of factors. Research has shown that temperatures above 90°F are unfavorable for most crops, since they lead to an increase in the rate of metabolism, which in turn increases the stress levels for other biological processes in the plants. Don't choose plants that require full sun if you live in a shady woodland. A little research will go a long way. Opt for vegetation whose natural defenses will keep it healthy, without a great deal of attention or external influences.
Healthy plants are not generally prone to insect infestations.
Once the plants are in place, buckwheat hulls are my favorite choice for mulch, keeping moisture in and weeds out.
Synthetic fertilizer can not achieve this. Fungal diseases run rampant when plants are planted too closely. Refer to your seed packet or starter plant instructions for more information.
* Seeds from plants that thrived under organic management should produce plants that fare better when grown organically in their turn, but as far as I know there has been no scientific trial of this thesis.
Whereas chemical based agriculture attempts to change the environment to suit the crop by using chemical additives and fertilizers etc. They tell a lot about the health of the soil. Check your soil frequently with a pH kit and correct the soil pH when necessary.
Chemical fertilizers add nothing to the soil, and can in fact have harmful effects. Organic
Organic pest control uses nature's own methods to keep destructive insects in check, and so allows your garden to maintain a healthy diversity of organisms.
Chemical fertilizers and additives will, over time, damage the soil's ability to provide what plants need to resist disease, insect attacks, and stress.
They can be spread through the air on spores, pollen and by insects.
If that was the case, you could eat peach seeds with impunity, curare would be no big deal, and pig farms wouldn't have such nasty reputations.
