Frequently Asked Questions

AI
Organic options like poultry manure or seaweed improve soil structure over time, while synthetic feeds like Miracle-Gro offer immediate nutrient boosts. Choose based on your long-term soil health goals and how quickly you need results.
Liquid feeds typically require application every one to two weeks during the growing season. Slow-release granules, such as Renaissance, may only need applying once or twice a year. Always follow the specific instructions on the product packaging.
Epsom salts provide magnesium and sulphur, which benefit leafy greens and tomatoes. However, they should be used sparingly and only if a deficiency is suspected, as overuse can imbalance soil nutrients and harm other plants.
