As the gardener prepares for planting, what indicators should be observed in the environment, like the behavior of nature or the characteristics of the soil? In essence, at what precise moment, factoring in all these variables, should engagement with the earth occur to achieve the most fruitful tomato harvest? What guidance can be drawn from expert recommendations?
