Failing to prepare cannabis gardens in the fall can lead to poor soil health, nutrient deficiencies, and increased susceptibility to pests and diseases in the next growing season. In regions with naturally acidic soils, such as the East Coast, neglecting to address pH imbalances can result in toxic levels of aluminum and manganese, as well as reduced phosphorus availability. Additionally, leaving plant debris in the garden can harbor spores of bud rot, powdery mildew, and pest eggs, which may lead to recurring issues. Proper fall preparation is crucial to mitigate these risks and ensure a productive harvest next year.
