Pro-Tips from Kent Countryside Nursery:
Prevention is Better Than a Cure: Fungal spores spread incredibly fast in warm, muggy Putnam County weather. Don't wait until your plants are completely covered in white film or black spot to act. Start treating your vulnerable plants—especially tomatoes and squashes—preventatively in early summer or at the absolute first sign of a spot.
Safe Right Up to Harvest: A quick note for backyard farmers! Because this formula is fully approved for organic gardening, it is completely safe to use on your edible vegetables, herbs, and fruit trees right up to the very day you harvest them. Just give your produce a standard rinse before bringing it to the kitchen table.
Avoid the Midday Heat: To protect your plants from getting leaf-burn, always apply this spray in the early morning or evening when temperatures are cooler and the hot afternoon sun isn't shining directly on the wet foliage. Be sure to shake the bottle well and thoroughly coat both the tops and the undersides of the leaves.
