How To Manage Cannabis Wind Burn

What is cannabis wind burn?

Cannabis wind burn is a condition that can affect cannabis plants when they are exposed to excessive wind. It occurs when the leaves of the plant experience high levels of wind stress, leading to damage and a range of negative effects on the plant’s growth and development.

The primary symptoms of wind burn include dry, wilted, or burnt-looking leaves that may appear scorched or yellowed. In severe cases, the leaves may also curl, wither, or fall off the plant entirely.

Wind burn on cannabis plant can also weaken the plant’s overall structure and make it more susceptible to other environmental stressors, such as pests or diseases.

How does wind burn happen?

Wind burn occurs when cannabis plants are exposed to excessive amounts of wind that cause physical damage to their leaves and other cannabis plant tissues. When wind speeds exceed a certain threshold, the leaves of the plant can become dehydrated and scorched, leading to a range of negative effects on the plant’s health.

The wind causes damage to the plant in several ways. First, it causes the plant to lose water more quickly through a process called transpiration. As the plant loses water, its leaves can become dry, brittle, and prone to breakage.

Second, high winds can cause physical abrasion of the leaves, which can lead to tissue damage, scarring, and discoloration.

For novice growers, it can be challenging to differentiate wind burn from other stressors that can affect marijuana plants and produce similar signals. However, there are specific indications that set wind burn apart, and growers should pay attention to them. Here are some signs to look out for to identify wind burn in your cannabis crop.

What are the cannabis wind burn symptoms?

Marijuana wind burn can have a range of common symptoms, and they can be challenging to differentiate from other types of stress, such as nutrient deficiencies or pest infestations.

However, some common signs of wind burn include leaf damage, discoloration, wilting, and drying out. In severe cases, wind burn can lead to stunted growth, reduced yields, and even death of the plant. Growers need to identify and address wind burn promptly to prevent significant damage to their cannabis crop.

Clawed leaves

Clawed leaves

Clawed leaves or otherwise known as wind burn, is a common symptom seen in cannabis plants. It occurs when the tips of leaves curl under due to high amounts of wind force. In an effort to protect their foliage from further damage, your plant will goes into a defensive position in order to minimize potential harm.

It’s possible that because the clawed shape resembled an issue with nitrogen toxicity, it can be easy to misdiagnose the problem. Therefore, it’s important to look for indicators of wind burn such as leaves closest to the fan being more affected than those further away from the fan’s direct path.

If this pattern is observed, then you likely have a weed wind burn problem and should take steps accordingly in order to maximize your plant’s health and growth potential.

Burnt leaf edges

The edges of burnt leaves are a common sign of stress caused by the wind. Plants exposed to high winds will suffer from disrupted photosynthesis and other harmful effects, sometimes resulting in burnt leaf edges.

In mild cases, the leaves may be dry and withered on the tips, but in more severe cases, the entire leaf can become desiccated and blackened around its edges. This problem is usually found on older growth – as new leaves are more structurally resilient and better protected by existing foliage.

If you find your plants have burnt edges, check the foliage of other nearby plants to make sure you’re dealing with wind burn. Different environmental conditions can cause similar damage on plants – salinity or frost may give rise to dryness or discoloration near plant tips – so ruling out other causes is important.

Stunted growth

Stunted growth in cannabis plants can occur for a variety of reasons, including nutrient deficiencies, pests, diseases, or environmental stress factors. One such stress factor is wind burn, which can cause the leaves of a cannabis plant to become dry, discolored, and curled.

This can lead to stunted growth, as the plant’s ability to photosynthesize and produce energy is reduced.

Spots on leaves

Spots on the leaves of a cannabis plant can be a symptom of wind burn. Wind burn can cause the leaves to become dry, which can lead to the formation of brown or yellow spots.

The spots may be irregular in shape and size and can appear on both the top and bottom of the leaves. Over time, the affected leaves may become brittle and curl or deform, which can further reduce the plant’s ability to photosynthesize and produce energy.

In severe cases, the spots may spread and cover a large portion of the leaves, leading to leaf drop and stunted growth.

How To Protect Cannabis Plants From Wind Burn

Protecting cannabis plants from wind burn is essential to ensure healthy growth and maximum yields. Wind burn occurs when strong winds cause the leaves to dry out, leading to discoloration and damage. To prevent wind burn, it is important to take measures to protect your plants, whether indoors or outdoors.



Growing cannabis plants indoors can provide protection from wind burn and other environmental stress factors. Here are some steps you can take to protect your indoor cannabis plants from wind burn:

  1. Provide adequate ventilation: Good ventilation is important for preventing wind burn in indoor grow rooms. Make sure that the air is circulating properly and that there are no dead spots where the air is stagnant.
  2. Avoid placement near fans: Fans can cause wind burn by drying out the leaves of your plants. Avoid placing your plants near fans or other sources of strong air currents.
  3. Use a humidifier: Indoor grow rooms can be very dry, which can increase the risk of wind burn. Using a humidifier can help to maintain the proper humidity levels and reduce the risk of wind burn.
  4. Provide shade: The risk of windburn in cannabis plants can be elevated by exposure to direct sunlight, making it important to provide shade, particularly during the hottest hours of the day. To accomplish this, utilize shade cloth or other materials to establish a protective barrier against direct sun rays.
  5. Water your plants regularly: Maintaining regular watering schedule for your indoor plants is essential in ensuring their leaves remain hydrated and protected from wind burn. It is crucial to deeply water the plants and avoid excessive watering, as this may cause other problems.


Growing cannabis plants outdoors can expose them to direct wind burn and other environmental stress factors. Here are some steps you can take to protect your cannabis wind burn outdoors:

  1. Choose a sheltered location: Growing your plants in a sheltered location can help to protect them from strong winds. This might include planting them near a windbreak, such as a wall or fence, or in a naturally sheltered area.
  2. Provide shade: Direct sunlight can increase the risk of wind burn, so it’s important to provide shade for your outdoor plants, especially during the hottest parts of the day. You can use shade cloth or other materials to create a protective barrier.
  3. Increase humidity: High humidity levels can help to reduce the risk of wind burn by keeping the leaves of your plants soil moisture. You can increase humidity levels by misting your plants or using a humidifier.
  4. Water your plants regularly: Regular watering can help to keep the leaves of your outdoor plants hydrated and reduce the risk of wind burn. Make sure to water deeply and avoid over-watering, as this can lead to other issues.
  5. Use wind-resistant varieties: Some cannabis strains are more resistant to wind burn than others. Consider choosing a wind-resistant variety for your grow space if you live in an area with strong winds.

The good news is that there are ways you can help treat wind damage and prevent it from reoccurring. First off, investing in some kind of protection for your plants should be top priority; something like fencing or even hay bales may provide enough cover for your crop.

If you already have a windy environment, try trimming back any exposed branches or limbs so only strong parts remain, this will create less drag on your plants in high winds.

Lastly, ensure you keep an eye on humidity levels particularly when daylight lasts late into much hotter evenings – increase the moisture through misting and make sure pruning is done appropriately to reduce stress from extreme temperature changes.

Can plants recover from wind burn?

Yes, in many cases, cannabis plants can recover from wind burn. However, the extent of the recovery will depend on the severity of the wind burn and the overall health of the plant. If the wind burn is minor, the plant may be able to recover on its own, given time and proper care.

However, if the wind burn is severe, it may be necessary to take additional steps to help the plant recover, such as pruning damaged leaves and providing additional nutrients and water.

It’s important to monitor the plant closely and take action promptly if you notice any signs of wind burn. The earlier you catch and address the issue, the more likely the plant is to recover fully.
