What Is Epsom Salt And Why Is It So Important For My Cannabis Garden?
There are many different ways to modify your garden into a more organic, natural environment for your cannabis plants to live in. Using natural ingredients is one way to ensure the best quality plants, and luckily for you, there are plenty of natural sources for your plants to get all the nutrients they need. Here, we will be looking at Epsom salt for cannabis growth and what it can do to benefit your growing ambitions.
Origins Of Epsom Salt
Epsom salt, the nickname given to magnesium sulfate, is a compound that was discovered in underground springs in the town of Epsom, England. It is a natural and organic source of both magnesium and sulfur. Epsom salts are commonly used in bath salts, exfoliants, muscle relaxers and pain relievers. However, these are different from Epsom salts that are used for gardening, as they contain aromas and perfumes not suitable for plants.

Why Should I Use Epsom Salt For Cannabis?
Using Epsom salt for cannabis plants is extremely important for those who want to begin implementing more organic ingredients in their gardening habits. When using Epsom salt for weed, it’s almost impossible to overfeed your plants. At the same time, it provides them with a healthy dose of micronutrients that are crucial for strengthening their cell strength and overall immunity.
A Natural Source Of Nutrients
Epsom salt is an excellent addition to your gardening routine, as it’s a natural source of two of the most important nutrients for cannabis plants: magnesium and sulfur. Using Epsom salt for cannabis will allow a gardener to rely less on synthetic nutrient supplements or specialized, fertilized soils. Adding organic ingredients like Epsom salt to the diet of your cannabis plants will therefore ensure healthy soil and a healthy lifecycle.
The Importance Of Magnesium in Epsom Salt
Epsom salt is a natural source of magnesium – one of the most important nutrients to a plant’s life, as it encourages its uptake of essential nutrients like nitrogen, phosphorus and potassium. Magnesium is also important for your plant’s development of chlorophyll, the component responsible for your cannabis’ ability to absorb sunlight, which allows photosynthesis to occur by strengthening cell membranes. Overall, a healthy level of magnesium is what’s responsible for the successful and healthy growth of your cannabis plants.

Why Do Plants Need Sulfur?
Sulfur is the essential basis for your plant’s immune system. Sulfur facilitates the production of amino acids, enzymes and vitamins in your plant, all of which aid in the healthy growth of a plant and build up its immune system. In other words, a healthy base of sulfur in your garden will help prevent your plants from getting sick. Sulfur is also essential for your plants to create chlorophyll. Most importantly, it works together with magnesium to secure the plant’s uptake of nitrogen, phosphorus and potassium, or NPK – the most essential nutrients to a cannabis plant’s survival.
Bring Epsom Salts Into Your Garden To Prevent Deficiencies
Now that we know why magnesium sulfate, or Epsom salts, are so beneficial to plant health, we can apply this knowledge to our own marijuana grow ops. Using Epsom salt for cannabis gardens is an excellent way to prevent or treat magnesium deficiencies that will negatively impact bud growth, or sulfur deficiency, which can harm plant growth and cause discoloration.
The Right Time To Incorporate Epsom Salt
You can begin using Epsom salt for cannabis plants within the beginning of each lifecycle, when the plants are just a few inches tall. You should, however, cease using Epsom salts during the first week of flowering, as this can alter the growth of buds. Generally, a good amount of magnesium and sulfur throughout a plant’s life will ensure a high yield.
How Much Epsom Salt To Apply And How?
The ideal amount of Epsom salt for cannabis plants is one tablespoon per 5 liters (1.3 gallons) of water, or about one teaspoon per 3.7 liters (1 gallon) of soil. You can use Epsom salt for weed growth as a topical foliar spray when diluted with water, or incorporate Epsom salts directly into the soil or substrate. It’s a great way to prevent or treat magnesium or sulfur deficiency.
Start Using Epsom Salt Now
Epsom salt is an excellent way to ensure proper nutrient levels in your garden by using natural sources for organic ingredients. As proper levels of magnesium and sulfur are critical to healthy cannabis plants, using Epsom salt for cannabis can be considered a necessary addition to your gardening shed. Whether you want to start a new substrate or are looking for a natural way to cure some nutrient deficiency, Epsom salt and marijuana makes for the perfect team.

Vinegar and Epsom salt: It’s not the cure-all for weeds
Darren Strenge (Photo: Contributed photo)
As gardeners, we like to think we work with nature, and that is true to some extent. Despite attempted cooperation, nature is hedging its bets on our garden plots. Just in case we don’t fill our plots with plants, nature has a horde of plant seeds (we call them weeds) waiting to come in and grow. Unfortunately, nature just assumes we will fail and those seeds promptly germinate to take over without asking how we feel about it. How rude.
So, to keep our gardens happy, we get out there and pull most of the weeds. When there are too many, we may get out the weed torch (be careful!) or our sprayer and apply some sort of herbicide (read the label!). Whatever your stance is on the use of garden chemicals, I hope you use them as an absolute last resort. But don’t worry, I’m not writing today about the general pros and cons of herbicides. Partly because I have a different but related topic in mind, but mostly because I don’t want a torch and pitchfork-wielding mob at my doorstep.
Instead, I want to discuss the use of vinegar and salt/Epsom salt as a weed killer in our gardens, sidewalks, and driveways. But before I do, let’s briefly mention an important safety note. Be on the lookout for Giant Hogweed and Poison Hemlock, two outright dangerous weeds. Please go look them up on the Kitsap County Noxious Weed Program website (extension.wsu.edu/kitsap/nrs/noxious) right now. Both species are contact and ingestion poison hazards. Touching or tasting them can potentially cause you great harm. You absolutely do not want them growing in your yard, especially if you have children or pets. Don’t bother spraying them. Don’t even touch them. Instead, contact the Kitsap County Noxious Weed Program (WSU extension) for advice. You can report an infestation via their website.
So if your weeds don’t include Giant Hogweed and Poison Hemlock, vinegar might be an option for you. Vinegar from the grocery store mixed with salt has become popular over the last several years as a homemade weed killer. Before you go mix up a tank, however, there are some things you should consider first. It may help or not be worth the trouble depending on your situation.
The vinegar and salt mix is a contact weed killer, meaning that it only kills the part of the plants that it touches. Contrary to some myths that I’ve read, a foliar spray absolutely does not kill roots. Most weeds sprout back from the roots within a few short weeks of being sprayed with vinegar. Repeated sprays may keep the weeds in check and some of them will peter out and die eventually. But, beware. Repeated sprays with vinegar and salt are problematic.
Vinegar alone can kill weeds under the right circumstances, and adding salt significantly improves its efficacy, but salt is a double-edged sword here. Applying the salt and vinegar mix repeatedly can lead to a plant-unfriendly build-up of salt in the soil. The term “salting the earth” came in part from the practice of applying salt on soil to prevent plants from growing, and frequent use of salt and vinegar weed killer can lead to similar results.
If you insist on repeated use, give strong consideration to giving your garden a good deep watering occasionally to flush the salt through. If you are using regular table salt in your mix, sufficient watering and occasional deep watering should help alleviate salt build up. “Should” is the operative word here. Don’t go nuts with your salt and vinegar weed killer.
Some recipes call for regular table salt. Many call for Epsom salt. Both will work and a build-up of both in your garden soil is bad. Too much of any salt can lead to wilting and dead plants, and while using Epsom salts avoids table salt’s potential for sodium toxicity, excess magnesium from Epsom salts can interfere with phosphorus absorption in plants (that’s bad). Epsom salts provide the plant nutrients magnesium and sulfur but, like any fertilizer, overuse can be detrimental to your plants.
The popular vinegar and salt weed killer can be a useful tool in our control of weeds, but it is not a cure-all. Be careful where and when you apply it. Like any medicine, too much is not good. Incorporate other methods of weed control. Go ahead and pay the neighbor kid five cents for every weed pulled. Just check to make sure they get the roots with the tops.
Repeated use can have harmful consequences to your garden.
