What is windburn in cannabis?
Windburn in cannabis is a stress reaction of the plant caused by strong and constant winds. These winds damage the leaves and stems, resulting in limited nutrient uptake. The result is yellowed and necrotic leaves, which can impair the plant's growth. Importantly, windburn is not caused by disease or pests, but by external environmental factors. Understanding these causes is the first step to better protecting your plants.
How to identify the first signs
Recognize cannabis windburn
The first signs of windburn in cannabis are often subtle, yet clear warning signs. You will notice that the edges of the leaves start to yellow and curl upwards slightly. This yellowing usually occurs first on the upper leaves, as these are most exposed to the wind. Another sign is the appearance of brown or necrotic spots on the leaves. These occur because the plant is not supplied with sufficient nutrients due to the continuous exposure to wind. If you recognize these symptoms early, you can take quick action to minimize the damage.

Cannabis windburn symptoms
If your cannabis plant shows symptoms of windburn, it is important to act quickly to limit the damage. First, you should carefully remove the damaged leaves to allow the plant to focus its energy on the healthy parts. This also promotes air circulation and reduces the risk of further damage. Make sure that you protect the plant from further strong winds, for example by erecting a windbreak or moving the plant to a more sheltered location. In addition, it can be helpful to provide the plant with a light fertilizer to support the healing process.
Tips for restoring your plants
Cannabis leaves and windburn
After a windburn, it is crucial that you help your plants to recover. A first step is to strengthen the root zone through regular but moderate watering - this will prevent the plant from suffering from additional stress. Also use a plant-strengthening fertilizer rich in potassium and phosphorus to promote the growth of new leaves. A temporary reduction in light exposure can also be helpful to allow the plant to fully recover without experiencing additional stress from strong light. Remember to check your plants regularly and remove any other damaged parts immediately so that the plant can regenerate better.
Windbrand im Grow: So verhinderst du Schäden
Windbrand kann im Grow schnell auftreten, wenn Pflanzen ständig starkem Wind ausgesetzt sind. Indoor solltest du Ventilatoren so ausrichten, dass sie die Luft nur sanft bewegen, anstatt direkt auf die Pflanzen zu blasen. Outdoor helfen Windschutznetze, Mauern oder Hecken, um starke Böen abzufangen. Junge Pflanzen sind besonders empfindlich – stütze sie mit Pflanzstäben, damit sie nicht abknicken. Eine gute Nährstoffversorgung mit Kalium und Phosphor stärkt die Pflanze zusätzlich und macht sie widerstandsfähiger. Mit diesen Maßnahmen schützt du deine Pflanzen und verhinderst Windbrand im Grow effektiv! 🌱💨
