You’ll need to develop the perfect outdoor cannabis soil mix for big, beautiful buds to flourish.

We understand that you might need some guidance to get things right the first time. We know you’re picturing yourself lighting up that first fat joint and don’t want you to be disappointed.

Starting to Grow Weed Outdoors Using Soil

There are many benefits to growing weed outside, including:

  • Lower costs
  • Big yields
  • Environmentally friendly
  • Fun and relaxing

Choosing the best soil to grow cannabis outdoors means you’ll need to stay on top of monitoring the acidity, texture, and pathogens (pests in the ground). 

If you opt to make your own soil or purchase sterile earth, you’ll have complete control over the acidity, nutrition, and texture

You need to be aware that planting weed in the ground gives your plants exposure to all the living organisms in the dirt, which is more challenging to create in a pot. 

The container you grow your marijuana in is fundamental to the life cycle and harvest of your plant.

Wherever you decide to plant your weed, a well-prepared outdoor cannabis soil mix is crucial to mitigate any issues throughout the different growth stages. As long as you nourish the earth properly, your plant will thrive, and you won’t need to intervene. 

Ultimately, excellent soil is the gateway to a healthy plant, which means an optimum harvest for you to enjoy to the fullest. 

Soil Texture and Composition

The best soil for growing cannabis outdoors is light, loamy, and drains well but retains enough moisture. Loamy means a mixture of sand, silt, and clay with a ratio of around 40:40:20. The following make up the composition:

  • Sand makes up a big part of many soils and consists of granular particles of rocks and minerals. Sand particles are between 0.05mm-2mm in diameter.
  • Silt is finer than sand, and the particles measure between 0.002mm-0.05mm.
  • Clay is the finest of them all, and particles are less than 0.002mm in diameter.

To test your soil composition, half fill a jar with earth and then to the top with water. Shake the pot and let the components settle over a few hours. You should see a layer of sand at the bottom, followed by silt and then clay. 

If you notice your earth is poor-quality, consider buying commercial soil to mix with the existing dirt

Planting in Pots or in the Ground

Once you’ve got your soil mix for cannabis outdoors ready, you’ll need to determine where you’re going to plant your weed. There are two primary options, pots or in the ground. Both methods have their benefits, so it’s up to you to decide which works best.

If you opt for pots, you have the advantage of using commercial soil, which, luckily for you, tends to be optimized for growing cannabis and is pre-sterilized. This earth keeps harmful microbes away and your plants well-nourished. 

There’s a downside, though. Your plants will be constricted within the container and may also require transplants and lots of watering. 

If you want to go all-natural, your plant’s roots can spread out and access the maximum amount of groundwater. Your cannabis will grow bigger and require far less maintenance, but there’s always the risk of exposure to pathogens in the soil and contamination. 

The seasoned weed growers may make it seem near impossible to create the best soil for cannabis outdoors, but fear not! Marijuana will grow almost anywhere, even on riverbanks. 

Make sure to watch your plants as they grow and adjust the soil when needed. Producing cannabis is a learning curve that you need time and patience for. The best way to learn is on the job.

We’re sure you’ve heard the phrase, ‘you are what you eat.’ The same applies to your cannabis seeds and plants, which is why quality soil is essential. The better the earth, the better your final harvest will be, and the more you’ll enjoy it. 

What is the best soil for outdoor weed growing? It depends on where you plant your cannabis. 

Best Soil for Growing Weed in Pots

When planting your seeds in pots, you have complete control over what goes into the mix. You can buy a commercial branded soil that’s all ready to pop your seeds into, or you can opt for some homemade compost. 

For first-time cannabis gardeners, investing in quality potting soil is the best idea. Marijuana outdoors grows with watering alone if you use the ‘super soil’ correctly without having to add any minerals or nutrients. 

You can make this earth yourself with a combination of worm castings, bat guano, and other components. Let it sit for a few weeks with some quality soil, and it’ll be good to go. We recommend adding a few stones to help with drainage.

Best Soil for Planting Weed Seeds in the Ground

The best soil for weed outdoors when planting in the ground is loam, which we mentioned is a mix of sand, silt, and clay. 

Test your soil with the glass jar method to check the ratio of each element and amend accordingly. You’ll also need to consider certain factors, including:

  • pH level
  • Water retention
  • Texture
  • Nutrient makeup
  • Drainage

A clay-heavy soil will drain slowly and won’t hold oxygen well. Dig large holes at least a month before you plant and mix in plenty of compost, worm castings, manure, and other organic matter. This technique allows for aeration, drainage, and lots of nutrients.

Sandy soil is easy to manipulate and drains nicely, but it doesn’t hold nutrients well. You’ll need to dig holes and add compost and peat moss to bind everything together.

Silty soil is ideal because it’s simple to work, holds moisture, drains well, and has lots of nutrients. This dirt is also very fertile and will welcome your seeds well.

Ideally, your outdoor soil mix for cannabis should be a blend of them all. You can add in store-bought earth with added nutrients to help maintain your plants healthy until harvest. Ensure you add fertilizer and sterilize the dirt if you don’t use a commercial brand.  

The Best Nutrients for Outdoor Soil Growing

For your seeds to grow to their full potential, your earth will need three essential nutrients. The best soil to grow cannabis outdoors should include the following in the fertilizer.

Nitrogen

This nutrient is the most essential for your plant’s growth, food processing, and chlorophyll creation. You’ll notice a lack of nitrogen if your cannabis starts turning yellow and stops growing taller.  

Potassium 

When your soil doesn’t contain potassium, leaves will turn light green to yellow. The nutrient aids proper growth and helps with the reproduction of your plant. Potassium also affects the shape, size, color, and taste of your weed.

Phosphorus 

Playing a vital role for seedlings and young plants, phosphorus helps cell division, promotes root growth, and aids the development of the growing tip

How to Get the Best Soil Mix for Cannabis Outdoors

As mentioned earlier, you can buy a soil mix or make your own. Here are a few things to consider and look out for in either situation.

Buying Pre-Made Soil Mixes

If you decide to buy the best soil for outdoor weed from your local garden store, you’ll come across a variety of amendments, such as:

  • Bat guano
  • Peat moss
  • Perlite
  • Plant food
  • Worm castings
  • Bone meal
  • Biochar
  • Compost
  • Fish meal
  • Glacier rock dust

If the brand amends the soil heavily, there’ll be a huge list. Others create great structured soil with basic nutrients, leaving gaps to fill yourself. 

When looking for something that’ll help you throughout your plant’s life, opt for dirt that offers the correct pH level, balanced nutrients, and a loamy texture. This way, you won’t need to do a lot, if anything, yourself. 

If you like the idea of creating your soil mix but would like a little help, purchase a customizable option. With these bags, you can add your topsoil and liquid nutrients when you want, depending on your weed’s needs. 

Creating Your Own Outdoor Cannabis Soil Mix

Perhaps you decide to create your mix, so you’ll need to do a bit more work to keep your seeds happy. To make the best soil for growing weed outdoors, you’ll need to assess your current dirt first

Once you’re satisfied, you’ll need to look for a quality fertilizer to provide your plant with the three essential nutrients. The less nourishment your weed gets, the fewer buds it’ll produce. 

These nutrients need to be present throughout each growth stage, which means a lot of maintenance on your part. 

Keep in mind that shop-bought soils come already sterilized, which kills harmful bacteria, fungi, and insects. For your seeds to flourish, thorough sterilization is a must

The process takes a lot of time and effort, though, and there are other ways to control your pests by introducing beneficial microbes and insects into the soil. 

Checking pH Soil

How to Feed and Maintain the Best Soil for Outdoor Weed

Once you’ve started growing marijuana outdoors, you need to know how to feed and maintain your beloved plant. Neglecting your cannabis at any stage will result in poor quality weed or, even worse, losing your entire harvest.

Throughout your marijuana’s lifecycle, you’ll have to ensure it gets enough nutrients. You can buy ready-made mixes in a store or create your fertilizer. If you want to make organic food for your cannabis, we recommend these:

  • Blood meal or fish meal for nitrogen
  • Bone meal or bat guano for phosphorus
  • Wood ash or kelp meal for potassium
  • Dolomite lime for calcium and magnesium
  • Epsom salts for magnesium and sulfur

We advise against nutrients designed for indoor growth as they tend to contain synthetic mineral salts, which are damaging to bacteria in the earth

If you’re not sure how much fertilizer to use, it’s best to be conservative. You can always add topsoil if you notice deficiencies in your plants. There’s such a thing as too many nutrients, which could cause a nutrient lockout and ruin your crops.
