How often should I test my garden soil?
Nourish your outdoor container plants with Miracle-Gro Organic Potting Mix. This OMRI-listed mix contains quick-release natural fertilizer and feeds for up to 2 months, promoting healthy growth for flowers, vegetables, and herbs.
For established gardens, testing every 2-3 years is sufficient unless you notice plant health issues. New gardens should be tested before planting and again after the first growing season. Vegetable gardens benefit from more frequent testing (annually) because food crops deplete nutrients more rapidly. If you’re making significant soil amendments, test again 3-6 months after application to measure effectiveness and adjust your approach accordingly.
