Everyone knows aspirin as it is a hundred-year-old drug. Used for a multiple disorders throughout its history. New applications are apply to cure diseases. However, maybe not everyone still knows that we can also use aspirin to care for our plants. Let us see some uses of aspirin in the garden.
Research paper: aspirin help plants grow
At the University of Rhode Island, an experiment was done to sprayed on some plants. A solution was made of aspirin and water. The solution consisted of four tablets of aspirin dissolved in 4 liters of water. With this preparation, a group of plants was sprayed every three weeks throughout the growing season. At the same time, a group of plants is taken in same times that were not treated as experiment. At the end of the season, it was found that the treated group had developed better and had a higher production than the control group. It was concluded that acetylsalicylic acid improves the immune system of plants, which defends better the microbial and fungal attacks that can affect its growth.
According to the United States Department of Agriculture, plants can be treat with an aspirin solution to combat fungal diseases caused by verticillium and fusarium. It also serves to treat the blight. Especially effective is this treatment when applied to Solanaceae such as tomatoes and potatoes. Apparently all plants have in their composition a small proportion of acetylsalicylic acid that increases in situations of stress. By spraying aspirin on the plant, we increase its proportion of this active principle, which improves its resistance to external aggressions. You can also soak the seeds in an aspirin solution before using them at planting.
Do plants grow better with aspirin?
Perhaps this method is the best-known usages for a long time. At least I remember that my mother already used it and it consists in dissolving an aspirin in the vase water when we put cut flowers in it. They increase their duration considerably before drooping. Acetylsalicylic acid reduces the production of ethylene and thus delays the drooping of cut flowers. Moreover, the antifungal properties of aspirin delay the appearance of forms that obstruct the vascular tissue of the flower.
Aspirin can also help us to improve the rooting of the cuttings. Dilute an aspirin in distilled water and wet the cuttings here for a few hours before proceeding to the crop. It acts as a disinfectant and as a growth hormone. As we have seen, aspirin can serve us well in the garden but like everything in excess can be harmful. The recommended dose for any use is to dilute one aspirin tablet in one liter of water. A higher concentration can burn the leaves of the plant when pulverizing them. It is also advisable to practice the treatment in the early hours of the day to allow time for the leaves to dry and not bother the bees and other pollinators.
