Bio Advanced All-In-One Rose and Flower Care - Granules can be applied during high heat temperatures outdoors however you want to be sure that you do not apply the granules directly to leaves or other green parts of the plants. We recommend applying in the morning or evening when temperatures are at the coolest for the day rather than during the middle of the day when it’s the hottest. Follow the application directions per the product label.
