Buying Guide
FAQs
What is the difference between the Miracle‑Gro Performance Organics All Purpose Container Mix and the Organic Raised Bed and Garden Soil?
The Container Mix is a ready‑to‑use potting blend formulated for indoor and outdoor containers and feeds plants for up to three months, while the Raised Bed Soil is designed for in‑ground beds and includes a quick‑release natural fertilizer for faster establishment. Both are OMRI‑listed, but the Container Mix emphasizes aged compost for container vigor, whereas the Raised Bed Soil focuses on soil structure and nutrient release in larger garden beds.
How do the single 32 oz liquid plant food and the 2‑pack version compare in value and usage?
Both containers contain the same 94 % plant‑based formula and dilute to make about 10.75 gallons of feeding solution, but the 2‑pack offers a slight price advantage and ensures you have a backup when you run out. The single bottle is convenient for occasional use, while the pack is better for gardeners who feed multiple beds or need regular re‑applications every 7–14 days.
Which granule product should I choose for vegetables versus flowering plants?
For vegetables, the Performance Organics Edibles Plant Nutrition granules are optimized for fruiting crops like tomatoes and herbs, delivering nutrients that boost harvest size. If your priority is abundant blooms, the Performance Organics Blooms granules provide a higher phosphorus blend that encourages more flowers and vibrant colors.
How long does each product feed plants and how often should I reapply?
The All Purpose Container Mix and the Organic All Purpose Plant Food granules both feed for up to three months, with re‑application recommended every 4–6 weeks for granules and as needed for soil mixes. Liquid plant food works faster, showing results in a week, but should be reapplied every 7–14 days to maintain optimal nutrition.
Are the organic products OMRI listed and why does that matter?
Yes, every Miracle‑Gro Performance Organics product mentioned is OMRI‑listed, meaning it meets strict organic standards accepted by the USDA. This certification assures gardeners that the ingredients are derived from natural sources and free from prohibited synthetic chemicals.
What are the cost‑effectiveness considerations when buying bulk (e.g., 2‑lb bags vs 3‑lb bags)?
Larger packages, such as the 3‑lb bags of Organic All Purpose Plant Food, typically lower the per‑pound cost and reduce packaging waste, making them a better value for gardeners with extensive beds. However, if you have limited storage or only need a short‑term supply, the 2‑lb option may be more convenient despite a slightly higher unit price.
Can I use the Performance Organics Edibles Nutrition with indoor containers?
Absolutely; the Edibles Nutrition granules can be applied to both indoor and outdoor containers as long as you water the soil after spreading the granules. Just follow the recommended coverage rate and reapply every 4–6 weeks to keep indoor herbs and vegetables thriving.
