Buying Guide: Key Considerations for 12-12-12 Fertilizers
- What plants will you feed? Choose 12-12-12 if you need a general purpose feed for vegetables, annuals, perennials, and ornamentals. For containers, smaller bags may be easier to manage.
- Granular vs liquid: Granular formulations provide slow, even feeding over time, while liquid concentrates can deliver faster uptake when used with regular watering.
- Soil condition matters: If your soil is compacted, look for products that mention soil structure benefits or include micronutrients to support root health.
- Release rate and safety: Slow-release options reduce the risk of nutrient burn and provide steady growth, especially in hot weather or windy conditions.
- Container suitability: Containers and hanging baskets often need more frequent feeding; select smaller packages or ready-to-use formulations for easier dosing.
- Soil testing: Consider a soil test to tailor nutrient needs. Adjust feed based on existing soil pH and nutrient levels.
