The invention relates to an aqueous composition which is used to protect and strengthen plants, comprising: polyethylene glycol at a concentration of between 2 and 10 grams per litre of composition, whereby said polyethylene glycol has a molecular weight of between 6000 and 8000 grams/mol; vitamin A or a derivative or precursor thereof, including mixtures of same, at a concentration of between 0.1 and 10 grams per litre of composition; and at least one red colouring agent at a concentration of between 0.1 and 10 grams per litre of composition, said colouring agent enabling the passage of light at wavelengths greater than 600 nanometres. The inventive aqueous solution is particularly suitable for preventing biotic or abiotic factors that generate stress in plants, as well for quickly improving plants that are in said state. In one embodiment of the invention, the aqueous composition comprises at least one glucoside and/or at least one foliar fertiliser. The invention also relates to a method of applying said composition.
