Frequently Asked Questions

AI
Organic options improve soil structure over time and are safer for the environment, while synthetic fertilizers provide immediate nutrient availability for faster growth.
Frequency depends on the product; water-soluble types are typically applied every 1-2 weeks, while granular slow-release formulas may only be needed every few months.
While NPK (Nitrogen, Phosphorus, Potassium) is the base, calcium is vital for tomatoes to prevent blossom end rot, which causes the bottom of the fruit to blacken.
