Protecting your plants outdoors is fairly easy, you don’t even need to spend much. With a little bit of work you can build a small greenhouse to keep your plants safe from bad weather, have companion plants to protect them from pests or place a wire cage against predators. Remember that your plants can get attacked by bigger animals also, like moles, gophers, cats, and dogs so having the appropriate protection will save you from worrying at all. Ultimately, the goal of protecting your cannabis plants all comes down to the end result. Damage inflicted upon your plants by pests, adverse weather, animals, and disease all impact growing and plant performance. This can slow down growth and, if the damage is bad enough, impact yields at the end of the growing cycle. Therefore, it’s in your interest to do everything you can to protect your plants against such threats. Succeeding in this area, you’ll end up with the biggest harvest possible and the highest quality flowers you can achieve with the genetics you’ve chosen and the environment you’re growing in.
As you may know, cannabis can easily get stressed if you keep your plants in bad conditions for a long time, if this happens your plant can slow down growth, start to show signs of stress or even become a hermaphrodite and all of these things can affect your harvest.
Plants (not only cannabis) can and will get stressed if they get too cold, hot or get parts eaten by bugs or bigger animals, the most common elements you should protect them from are:
When your plants are kept in excessive heat they’ll start to curl their leaves to try to conserve the water left in them, if this keeps on going for too long they will start to yellow, get crispy, and die. If they suffer from extreme cold, the leaves can get frostbite and if the temperatures are too low the oxygen available will decrease, resulting in slower growth or no plant growth at all.
Cannabis plants need wind to strengthen the stem and branches but strong wind can not only snap the branches but also completely tear your plant from the ground or pot.
Rain increases the humidity and in combination with the right weather, your plant can get infected with bugs or mold, pests like whiteflies, spider mites, or fungus gnats can rot or kill your plant with ease.
There are a lot of bugs that feed on cannabis, some of them being easier to eliminate than others but all will damage your plant, not only this but cannabis also can get mold so keeping your plants safe is a must if you want a successful harvest. But remember, not all pests are visible. Many growers fall into the trap of thinking that all pests are present above the soil. However, this presumption misses out on the microscopic organisms that live below the soil line. Although many of these minute life forms are beneficial, some of them are classed as pathogens and can do great harm to cannabis plants under the right conditions. Thankfully, there is a range of techniques and strategies available to cannabis cultivators that they can use to protect their crop against these invisible foes. Some of these involve watering in the right quantities, and others involve using good guy microbes to your advantage.
When growing outdoors you also have to worry about predators, animals like gophers, moles, rabbits or even cats and dogs love to eat cannabis plants so you should take the appropriate safety measures.

Depending on what you’re dealing with, there are simple and effective ways to protect your plants, from building a greenhouse to using nature to your favour, growers have come up with ways of growing top-quality buds outdoors.
There are a lot of ways to protect your plants from these things and they’re not expensive, they just require a bit of work, obviously, you don’t need to have all of them but prevention is essential when growing cannabis. The best way to use these things is to first know what things you think you’ll deal with and then use them in combination, for example, if you know your plants can get attacked by cats and you know the weather will be bad, you can build a greenhouse with a wire fence around to prevent animals from going in.
A greenhouse is fairly easy to build, by having a covered structure you can protect your plants from rain, snow, wind, and harsh weather.
There are several ways to build a greenhouse and it really doesn’t matter what it’s made of as long as it has the basic structure and it’s sturdy enough, this structure will allow you to cover your plants with a plastic sheet when you need to protect them from cold, rain or snow and you also give you the option to cover them with a shade net for hotter days.
Companion planting basically consists of adding other plants to your cannabis garden, plants like lavender, basil and peppermint (and a lot of other plants) produce chemicals that can help keep bugs off.
The strong aroma some of these plants produce will make insects go look for other plants to feed on, although you have to be careful because some plants can spread super fast and can limit the space your cannabis plants have so it’s better to have them in pots.
Some bugs can attack your plants but others actually protect them, using beneficial bugs like companion plants and it’s a good natural way to get rid of pests.
Some insects like the praying mantis, parasitic wasps or ladybugs can help you keep bad insects away from your plants because they feed on caterpillars, crickets and other bugs that may attack your crop.
Have in mind that beneficial bugs won’t eliminate a bug infestation if it already started but are a way to prevent an infestation because they will get rid of those bugs before they start to reproduce.

A wire fence is used to protect plants from bigger animals, cat, dogs, and rabbits (among others) can eat your plants, a lot of animals are attracted to cannabis plants and because of their size, they can kill your plant quite fast so it’s essential to have a wire fence or wire cage around your plant and also underground, protecting the roots from animals that you can’t see, like gophers and moles.
Diatomaceous earth (also sometimes referred to as kieselgur/kieselguhr) is a naturally occurring sedimentary rock that presents as a fine white powder. Its consists almost entirely of diatoms, which are the fossilized remains of tiny marine organisms. When added to the soil mix it offers a range of benefits – water retention, nutrient uptake, and pest control being the main three.
The fine, abrasive nature of diatomaceous earth makes it a great insecticide-free option. It works by slowly stripping away the exoskeleton of the pests, resulting in the bugs dehydrating and slowly dying. As it is chemical-free, the insects can not build any natural immunity as they sometimes do to chemical pesticides. There are 2 grades of diatomaceous earth – food and filter grade. It is also sourced from both fresh and saltwater quarries. Make sure to buy freshwater, food-grade diatomaceous earth for use with any gardening. This organic pesticide has been proven to be effective against a range of insects such as :
It is very budget-friendly and easy to use, so really everyone should be adding diatomaceous earth to every soil mix. Even though these tips are super effective and will surely prevent a lot of problems, remember it’s essential to check on your plants every day and make sure they’re fine, some things can kill a plant really quickly so checking on them every day is the best way to prevent problems.
You can’t see the fungal pathogens that reside in the soil. To fight them, you need to get on their level. As a cannabis grower, you have a range of beneficial microbes at your disposal when it comes to waging this invisible war. Mycorrhizal fungi are one of the greatest allies when it comes to defending your plants against root disease. These species fuse with plant roots and act as symbionts. As well as giving plants nutrients and water in return for sugars, they help to fight off disease-causing microbes. Trichoderma species are also great at helping to fight off pathogenic fungi. You can inoculate plant roots with these microbes during transplanting in the seedling stage to protect them later on in the growing cycle.
You can take all the precautions in the world to help ensure your plants don’t suffer from infestation issues, problems brought on by inclement weather, and damage caused by wild animals – but if you don’t keep your grow private and secure, all this hard work may be for absolutely nothing.
We all remember the movie “Fight Club” right? If you haven’t seen the film, it’s about a secretive underground fight club that has a few rules. The first and second rules are: ” You do not talk about fight club”. That’s exactly how you should approach cannabis cultivation. Of course, this is more important in places where the prohibition of cannabis hasn’t yet been repealed or overturned, but even in legal areas, it is always recommended to keep your mouth firmly shut about any grow op you work on.
Police and law enforcement will always be an issue, but they’re not the only thing you have to worry about. “Rippers” or weed thieves are constantly on the lookout for unsecured grows to raid, and this has become a huge problem in certain legal states. If everyone and their grandmothers are growing huge, sticky bushs’ of the good good in their own backyards, it makes finding and stealing cannabis grows super easy. So, remember to be very selective about just exactly who you share info with, and keep that sharing to an absolute bare minimum.
Growing outdoors has a lot of benefits but there are basic safety measures we should have so we don’t risk ending up without a harvest, depending on your growing space you can use some of these methods in combination to make sure your plants are safe at all times.
