There is NO EXCUSE today for a gardener to use chemicals. Perfect Lawns? Pristine Roses? Immaculate Flowers all Summer long? If you live in the Northeast/Atlantic Coast, I'll guide you down the non-toxic road to Organica - and you will not believe how easy it can be. Yes, it can be complicated, but backing off from Ortho and Scotts is not as hard as you think. Your neighbors won't believe their eyes. I have intelligent answers on soil care, bug killing, weed control and fungus-freedom!
I have college credits in horticulture and botany, and 30 years of gardening for personal pleasure. Plus I am a volunteer docent at the local botanical gardens. But a person's real gardening skills are learned from trial and error. I am strict about not using chemicals in the garden. Always have been. Always will be.
