Isolate and identify your plant's disease

Rest assured, a plant's disease is not necessarily irremediable. First of all, when you notice that your plant is sick, it is important to keep it away from your other plants to avoid any risk of contamination. Afterwards, remember to check that you are scrupulously respecting the maintenance of your plants. If not, your plant may not be sick but its care probably needs to be readjusted. We therefore advise you to check your plant's care sheet. You can also take a look at our infographic below to identify the problem.

Plant diseases, easy to identify

Below we have listed the most common diseases found in plants, as well as our solutions to restore their health.

Powdery mildew: a disease that affects many plants:

Do you notice a white powder on the leaves, flowers or stems of your plant?  This is powdery mildew. This disease is caused by insufficient watering and a lack of air. It usually occurs in May during dry weather. In this case, remove the parts attacked by this white deposit and adjust your watering as well as the ventilation of your room.

Mildew: A gardener's nightmare:

Do you notice brown spots on the leaves of your plants with mold, like white down, on them? Your plant is most likely affected by mildew disease. If this is the case, remove the affected leaves and stop spraying them. Indeed, the fungus can develop even more if the foliage is wet. You can also add garlic decoction to fight mildew (this technique also works against rust and aphids). This disease is very common in vegetable gardens where rain, humidity and mild temperatures encourage its development.

Root rot:

Drought or overwatering your plant can cause its roots to rot. You will first notice that your roots turn black, and then rot completely. In this case, unfortunately, there is no other solution than to throw away the contaminated plant.

Appearance of black spots:

You notice black and yellow spots on your foliage. Sometimes, some of your leaves come loose and fall. In this case, you will need to remove the stained leaves immediately to leave only those in good condition. Your room must lack ventilation, so remember to open your window from time to time to circulate more air.

Rust:

This disease mainly affects garden plants. You will see brown and orange spots on the lower part of the leaf as well as red spots on the upper part of the leaf. Too much watering (or rain) is the cause of this disease. To treat this infection, you can use natural fertilizer, at a higher dose than usual.
