While foliar spraying (or foliar feeding) your plants doesn’t really require any special growing skills, it can nevertheless be helpful to know how to do it right so you can get the best results. Let us take a closer look at foliar spraying; what it is and when you want to use it.

If you grow outdoors, buds getting wet can be a normal occurrence due to rainy weather. If a spray with some type of fungicide is the only way to save your precious outdoor crops from a mould infestation, use a natural, safe, and residue-free product only.
Because of the fast-acting way that nutrients can be provided to your plants via foliar application, this also makes it effective for providing your crops with boosters and stimulants when they need them. There are a wide range of products out there, most of which require foliar feeding as the method of application.

In addition to speed, foliar feeding has also other positive effects. When the plant is taking in nutrients via its foliage, this causes it to give off more carbohydrates into their root zone. This is beneficial for the microorganisms in the growing substrate that help assist with nutrient uptake.
What makes foliar feeding so special and an excellent way to address any type of nutrient deficiency is that spraying is much faster compared to applying nutrients to the soil via irrigation. The majority of the nutrients that you spray directly on your plants’ leaves will be absorbed in a very short time. The plants will also take in a much higher percentage of the nutrients this way. Studies have shown that foliar feeding is as much as 95% effective. This means plants take in almost all nutrients administered by spray, while they uptake a smaller percentage when fed through the soil.
Neem oil has the advantage of being a natural insecticide that also has some fungicidal properties. Cannabis growers use a neem oil foliar spray together with aloe vera juice and some type of emulsifier like potassium silicate to dissolve the oil. Weekly sprays during the vegetative phase can strengthen plants and increase their resistance against pests and pathogens.
Not all growers may be familiar with it, but most will at some point encounter a scenario where they should apply a foliar spray to their cannabis plants. The reasons for this are various; from treating your plants with insecticides or fungicides, to addressing a nutrient deficiency in the fastest way possible.
Some growers make their own foliar growth stimulators, for example by mixing liquefied aloe vera leaves with water or by using any number of DIY foliar stimulant recipes that you can find online.

Take note of the recommended nutrient strengths of your solution. Most of the time, foliar feeding requires a much lower nutrient strength than feeding your plants through soil. If the product that you are spraying doesn’t specify the proper amount for foliar application, start with half the recommended dose.

The vegetative phase refers to the period of robust growth in which plants develop their branches, stems, and fan leaves—but no flowers. During the early flowering stage, small buds known as “pre-flowers” begin to form at the nodes.

Now that we know how nutrients enter leaves, let’s take a look at why growers choose to foliar feed.

When making your foliar spray solution, be sure to follow the product instructions carefully. If you go overboard and add too many nutrients (or too many organic pesticides), you run the risk of damaging the leaves and potentially killing the plant.
High winds can also blow foliar feed off a plant. Save your solution for when the weather is compatible.
When a plant doesn’t have access to a particular nutrient, symptoms of deficiency can arise. These can range from discolouration and wilting to the full-blown death of a plant. Foliar feeding allows growers to directly target specific plants and leaves that display these symptoms. This enables a degree of accuracy much higher than adding extra nutrients to the soil.
It may just be a single plant that is struggling with deficiency. As opposed to treating the entire growing medium, foliar spraying is a highly localised means of correcting an issue.
Foliar feeding plants is a relatively simple process. But you need to be aware of what not to do. A slip-up here could cost you an entire plant. Follow these tips to ensure a fail-safe application.

Let’s explore how foliar spraying works, the advantages and disadvantages, and how to administer it properly.
