When soil supply falls behind
Plants need nitrogen to build chlorophyll, leaves, and stems. Much of the nitrogen in soil organic matter, compost, and many organic fertilizers must first be converted by soil organisms into a form roots can use. That process changes with temperature, moisture, and soil conditions.
During rapid growth, a plant can need usable nitrogen faster than the soil releases it. That temporary mismatch is the nitrogen gap. Growth may slow or older leaves may begin to pale.
Build the soil before the season. Feed the plant during the season.
Before planting, use finished compost and soil-building fertilizers—such as Dr. Earth products when they fit your plan—to feed the soil. Some of those products are labeled for in-season use; our preference is simply to do the major soil building before the crop is growing.
During active growth, Thriva feeds the plant directly, not the soil, in a form roots can use right away. Thriva is a focused 5-0-0 nitrogen fertilizer, designed specifically to feed the plant.
Why we prefer this timing: It helps match plant nutrition to active growth, and it limits broad soil-amendment applications around an edible crop. This is a precautionary approach—not a claim that properly labeled organic amendments are unsafe or that Thriva makes a garden pathogen-free. Product source, treatment, handling, animals, and water all matter.
