Understanding & Preventing Botrytis aka Bud Rot

Botrytis - Bud Rot

Cultivating healthy plants demands time, effort and vigilance. Yet, despite your best efforts, you may encounter issues like bud rot, mold or root rot. Recognizing these problems early and knowing how to tackle them is essential to safeguard your plants and maximize yields.

When humidity is high or plants are wet for at least 6 hours, declining or dying, soft tissues can become infected by airborne spores of Botrytis and Botryotinia species. Healthy, actively growing green plant parts are seldom infected directly by these fungi.

Understanding Bud Rot

Bud rot, also known as Botrytis, is a form of mold that thrives in the dense centers of buds in flowering plants. Initially, it manifests as a subtle discoloration inside the bud, making it challenging to detect. As it progresses, the affected area turns mushy and emits a foul odor. Left untreated, bud rot spreads rapidly, jeopardizing the entire plant.

Spotting mold-infected buds is crucial. If you notice any signs, promptly remove the affected areas to prevent further spread. While it's possible to salvage the rest of the plant if the infection is localized, extensive infestations may necessitate removing the entire plant.

Preventing Bud Rot

Prevention is the best defense against bud rot. It thrives in environments with high humidity, poor ventilation and dense foliage. Investing in environmental like dehumidifiers and air conditioning units can help regulate humidity levels. Additionally, selecting strains of plants known for their mold resistance can mitigate the risk.
Pruning and spacing plants effectively can improve airflow, reducing moisture accumulation. Moreover, maintaining a healthy soil ecosystem with diverse nutrients strengthens plant immunity against mold.

Dealing with Root Rot

Root rot poses a severe risk to your crops, typically arising from overwatering or poor drainage. When roots suffocate and decay, the plant's ability to absorb nutrients is compromised, leading to stunted growth. Prevention involves maintaining well-aerated soil, watering plants judiciously, and ensuring proper drainage.

Promoting Healthy Roots

Healthy roots are crucial for robust plant growth. Adequate oxygenation, achieved through proper soil drying and breathable containers, is essential for root health. Additionally, maintaining optimal soil temperature and watering practices fosters root development. Incorporating mycorrhizal fungi and compost teas can enhance nutrient uptake and root vitality.
