Use Insta-Green foliar spray for a deep, dark green in your foliar favorites. Like tanning spray for plants, Insta-Green is a darkgreening fertilizer, scientifically formulated to bring plants back to a lush dark color. Insta-Green fights yellow leaves in young seedlings and cuttings with extra iron, calcium, and nitrogen. Insta-Green is also great to apply when plants are stressed due to underfeeding or transplanting.
