The absence of rain or irrigation within the next 24 hours is vital, as the oil requires enough time to penetrate and work its protective properties. Applying neem solutions when rain is imminent may diminish its efficacy, as the water can wash away the oil before it can provide its desired benefits.

Similarly, strong winds can disperse the neem solution, reducing its concentration in the targeted mold-infested areas. As much as possible, it’s advisable to wait for a calm day with minimal wind activity to ensure the oil stays focused on the affected plants.

If you notice visible mold on the leaves or other parts of the plant, it’s best to address it before applying the neem solution. Wash the affected areas with water, using a soft cloth or sponge to remove any visible mold growth.

Keep in mind that this step not only helps eliminate some of the existing mold but also aids in improving the oil’s ability to penetrate the plant surfaces. As you prepare the plants, handle them with care, being mindful of their delicate nature. Remember to avoid excessive force or rough handling, as this may cause further damage to the plants.

This is because water droplets can prevent proper oil adhesion to the plant surfaces, reducing its effectiveness against mold.

While preparing the plants, take a moment to observe their overall health. Healthy plants are better equipped to resist powdery mildew infestations. Ensure they receive sufficient sunlight, appropriate watering, and proper nutrition as per their specific requirements.

By patiently allowing the solution to linger on the mold-infested surfaces, you provide it with the opportunity to combat the mold effectively and impede its further growth. The goal is to ensure that the antifungal compounds within the oil deeply penetrate the mold and disrupt its cellular structure, ultimately leading to its demise.
