And if, instead of asking the question “Why go for organic gardening”, we were to ask ourselves: “Why use chemical products in the garden?”. Chemical fertilisers?
Why use them, when the plants would be better nourished with compost? Pesticides? What’s the point when, by keeping the plants in good health and treating them with a few non-toxic products, we could resolve all the problems relating to pests and diseases?
Let’s begin by reminding ourselves that this, strictly speaking, is an agricultural practice aimed at growing a plant without water, often more simply called « soil-less » cultivation. In these types of crop-growing techniques, which can currently be applied to vegetables (tomatoes, cucumbers, peppers…) or many kinds of commercialised cut flowers or pot plants, the soil is replaced by an inert pH neutral substrate (rock wool, coconut fibre, peat, pine bark, pozzolana, clay granules…)! Generally speaking, the crops are placed in a protected environment (green houses or under plastic) where the climate is also rigorously controlled (moisture, temperature, sunlight) and irrigation is managed in a methodical and stringent manner (required because of the shallow rooting zone).
The wine-growers’ trade associations of the Côtes de Provence and Coteaux Varois regions and the producers of the PGI wines of the Var region, the Company Canal de Provence and the Chamber of Agriculture are working together to irrigate the vineyards of the Var region and offset the adverse effects of climate change.
