Frequently Asked Questions

AI
Powder reacts faster, making it ideal for urgent pH correction. Chips dissolve slowly, providing sustained acidity for acid-loving plants like rhododendrons over a longer period.
Sulphur is beneficial for acid-loving plants but can harm those preferring neutral or alkaline soil. Always test your soil pH before application to avoid over-acidification.
Apply in early spring or autumn. Powder may need reapplication every few months, while chips can last several months. Follow package instructions for specific dosage rates.
