Some of the most common cannabis pests include leaf miners, spider mites, whitefly, thrips, cabbage loopers, and aphids. Many people refer to inch-long looper caterpillars as “budworms.”

Depending on the region you grow in, you might experience different pests than others. Regardless of where you are, you want to nip the problem in bud before it grows.

Preventing Cannabis Pests

You must consider how badly these pests bother your cannabis crop before determining how you will treat it.

One important thing to consider is the health of your cannabis plants, which all starts in the soil. A plant with high-quality soil made up of quality compost, rich organic matter, and worms, will be able to fend off pests better than a plant in dry, nutrient-lacking soil.

The same thing goes if you grow your cannabis in synthetic fertilizer.

A few things you might consider adding to your soil to improve your plant health include:

  • Crab Meal
  • Aloe Vera
  • Seed Meal

Fighting Bugs with Bugs

While there are many insects you might fear seeing around your plants, there are many that you would like to welcome with open arms. There are insects you can introduce to your crop to fight off other pest insects. Some of the best examples of good insects include lacewings and ladybugs.

Ladybugs are ferocious little predators. They’ll kill everything from spider mites to whiteflies to aphids and beyond.

When releasing ladybugs, ensure you release them near a good food source so that they stick around. You should also make sure to release them at night so they rest in the environment you want them.

Amazingly Effective Pest Control Applications to Choose From

Conventional methods involve the application of chemicals to deter pests, but they often come with drawbacks. Many pesticides are harmful to your environment and unsuitable for human consumption. Additionally, using such chemicals puts your precious cannabis crop at risk of contamination.

Fortunately, there are alternative methods available to outdoor growers for minimizing pest invasions and the resulting damage. By employing these beneficial approaches, growers can protect their plants and reduce the loss caused by pests should an invasion occur.

For example, you can choose to go with organic pest-control compounds, which can ward off unwanted pests while keeping your soil healthy. There are plenty to choose from, so make sure to do your research to find the right product for your environment.

1. Do Companion Planting: A Natural Defense for Your Outdoor Cannabis Garden

Companion planting offers an excellent, holistic, and natural solution to ward off unwanted invaders in your outdoor weed garden. The beauty of this approach lies not only in pest control but also in the opportunity to enhance diversity by introducing other plant species. Some companion plants can even serve as a delicious addition to your dinner table.

Companion planting involves surrounding your cannabis crop with plant allies that generate positive effects, including reduced risks of pests and diseases. Unlike monocultures, where rows of the same plant species dominate, companion planting imitates the diverse ecosystems found in untouched nature.

The presence of diverse plant species within a polyculture increases local biodiversity to benefits multiple species, ultimately boosting the overall health and vitality of the ecosystem. By incorporating your marijuana crop into a polyculture system instead of isolating them on a cleared plot, you can effectively recreate a natural setting that protects your plants from pests.

Some examples of plant allies for your outdoor cannabis grow include garlic, mint, melissa, coriander, peppermint, and basil.

The strong aroma of mint confusing pests acts as a protective shield for weed plants. However, since mint has a tendency to spread rapidly, you should limit its growth to pots. Garlic chives also emit a powerful scent that confuses cannabis field invaders, and their leaves make an excellent garnish for culinary dishes.

In addition to companion planting, several other methods can help protect your outdoor cannabis grow from dangerous pests. Read on to learn about more such methods.

2. Introduce Beneficial Insects

Introducing beneficial insects into your outdoor cannabis garden can serve as a form of natural pest management strategy. For instance, parasitic wasps can effectively control caterpillar populations in your field, which can cause significant damage to your weed plants. Female wasps inject their eggs into living caterpillars, and the hatched larvae consume the caterpillars from the inside out. Though it may sound less appealing, this natural approach greatly benefits the health, vitality, and productivity of your marijuana (weed) crop. Another insect, called praying mantis, is known for its appetite for caterpillars.

3. Sterilize Your Soil

Sterilizing your soil is a proactive step to eliminate potential invasions from pests. Exposing your potting soil to high temperatures through a steam sterilization or solarization can help eliminate many harmful organisms.

4. Catch Airborne Pests with Sticky Pads

You can strategically place sticky pads around your marijuana plants to catch airborne pests such as gnats. When these pests land on the sticky pads, they become trapped, helping to reduce their numbers.

5. Use Diatomaceous Earth

To create a protective barrier against ground-dwelling pests like ants, diatomaceous earth can be used, which consists of microscopic fossilized shards. When anti-cannabis insects come into contact with sharp particles, they experience damage.

6. Consider Neem Oil

Neem oil, derived from the neem tree, is an effective deterrent for many anti-weed pests, including cannabis aphids. A mixture of neem oil and water, applied with a mister, helps combat various invaders.

7. Erect Netting to Deter Winged Seed-Eaters (Birds)

While we have focused on smaller anti-marijuana pests, larger creatures like birds can also pose a threat to your cannabis plants, particularly during the seed production stage. Erecting netting around your crop can effectively deter birds from approaching your plants while still allowing adequate sunlight penetration into your outdoor marijuana garden. However, it’s worth noting that birds can be beneficial too, as they prey on pests like caterpillars.

8. Train Your Pets Not to Harm Crops

For outdoor gardens where pets, like cats and dogs, may roam freely, it’s important to take steps to protect your plants from their mischief. Training your pets to respect your outdoor marijuana grow can allow them to enjoy the outdoors without harming your plants. In cases where additional security is required, fences and netting can be employed.

By implementing these techniques, you can create a thriving and naturally resilient outdoor cannabis garden, safeguarded from pest invasions.
