Using a foliar spray is a fantastic way to increase your plants nutrient intake if it is lacking. Also, if your plants have an insect infestation or some other kind of problem, it’s a great way to treat your plants with insecticides and the like. Here’s a quick guide to how and when you should utilise the foliar spraying method:
Many growers may be unaware of the benefits that come with foliar spraying, though there are definitely situations in which spraying plants is necessary. For example, if your plant falls victim to a fungal attack, foliar spraying can give your plants all the nutrients it may be deficient in as a result.
You shouldn’t use foliar spraying in place of any other methods by which you give your plants nutrients. In fact, plants typically take in all the nutrients they need to survive through their roots anyway. Although, foliar feeding can help supplement nutrients temporarily. One advantage of the method is the fact that it is incredibly quick, as well as the fact that plants nutrient intake will be much higher than if they were doing it themselves. Foliar feeding also increases carbohydrate production in the roots, which allows microorganisms to help with nutrient uptake.
As I’ve already said, using the spraying method can also aid in treating plants with insecticides. Doing so is actually very common, and there is no substance more popular to do so with than neem oil. Neem oil is a very effective insecticide and is, in fact, completely organic. Using the oil on a weekly basis during the vegetative stage can give your plants strength and help them build a defence against infestations.
As with most methods, there are particular times and ways to carry out foliar spraying so as to reap its full benefits. You should spray your plants in the morning or late in the afternoon, and should never, ever spray in direct sunlight as this can contribute to the burning of plant leaves. If you are an indoor grower, spray at the start or end of the dark period. Also, it is important to keep in mind that you should spray each leaf in its entirety, not forgetting the undersides as this is where the majority of the stomata are located.
So, there you have it, foliar spraying is an incredibly effective way to provide your plants with all kinds of things they may need. Hopefully this guide has jumpstarted your journey to foliar spraying, or at the very least, peaked your curiosity and increased your knowledge.
