Episode notes
Prioritize Calcium For Cell Strength
- Strengthen plant cell walls by boosting calcium and silica levels to reduce pest and disease damage.
- Foliar-spray calcium (e.g., calcium nitrate + fulvic acid) and correct cation balance to improve uptake and resilience.
Foliar Calcium To Overcome Immobility
- Apply foliar calcium regularly because calcium is immobile and translocates poorly into fruit.
- Use cheap options like calcium nitrate plus soluble fulvic acid or allowable organic inputs if certified.
Too Much Nitrogen Weakens Immunity
- Excess nitrogen, especially urea, suppresses potassium then calcium and increases pest susceptibility.
- Managing nitrogen and cation balance is crucial to maintain cell strength and reduce outbreaks.
