Do plants produce food from the sand they grow with?
Is it possible for plants to grow in sand?
Plants can not grow in sand alone. If you provide the necessary nutrients and water, as in Hydroponic gardening, then you can grow healthy plants in sand or gravel. But that is not 'sand alone'. Likewise, plants will grow well in sand that has organic material and other soil enrichers mixed into it. Again, that is not 'sand alone'. Plants can grow in just about any medium, as long as they have water and nutrients. Unfortunately, sand doesn't hold onto water and it contains no organic material, so there is nothing for plants to use for nourishment. As you can see at a beach or in a sand desert, some plant species have evolved to handle conditions close to 'sand alone', usually by sending roots down far enough to find water, or by growing very fast whenever there is a rain, or by absorbing the rainwater quickly and storing it for future use. However, even these plants can only survive where there are some nutrients mixed in the sand. Pure sand will not do. (Please note: this question concerns growing in 'sand alone', not 'sandy soil' or 'in a desert'.)
