In simple words, organic garden and landscaping is all about the soil.
Chemically you can grow basically anything. However, you will need tremendous amounts of inputs in order to grow plants with chemicals. If you use the 5 step chemical program you will be feeding the plant. Chemical fertilizer is applied to the lawn or garden. Water is needed to activate the fertilizer, which is water soluble. Some of the product will be lost to evaporation. More product will be lost by runoff and then,the rest will be taken by the plant. A huge percentage of that fertilizer is simply wasted creating serious damage to wildlife and to our water sources.
This action is repeated several times during the growing season. The grass, or plants will use up all the nutrients and will start to decline until the next fertilizer application. Chemical fertilizers are salt based, so they will dehydrate and kill the microbiology in the soil. Chemical fertilizers will also displace earthworms. So, now you will have no microbes, no earthworms to aerate your lawn or garden. Soil will become compacted. You will start to see all those weeds that love compacted soils like crabgrass, dandelions, plantain… The soil becomes dead. Diseases and pests appear. We start applying different products to get rid of pests. Crabgrass control, broadleaf weed control, grub control, fungicide… and you apply all this products for life.
Garden maintenance doesn’t have to be complicated
You put a product to get rid of something, and because of that, you will have to add another product to fix the damage done by the first product. Ultimately you keep adding things to fix the symptoms.
Organic land care takes care of the soil. You feed the soil, and in return the microbiology in the soil will decompose the organic matter, like grass clippings, organic fertilizer, etc… Those microbes will turn those materials into readily available nutrients for the plants.
Remember to feed the soil and not the plants.
