Task: Summarization
Input (English): This is a great product, so it's no surprise that the local shelves are often cleared of it, especially early in the season. Purchasing in bulk through amazon.com is a dependable alternative. Bayer 2-in-1 in granular form feeds roses and flowers while protecting them with a systemic insecticide for up to 6 weeks, but you'll need a separate fungicidal/disease treatment, and the systemic would not be something one would apply to anything edible. Bayer assures me the product is safe for pollinators and earthworms.
Output (English): Combo Rose Food/Systemic Insecticide
