How I Decide Which One to Buy

Before I buy, I think about my plants’ needs and how often I want to fertilize. If I want convenience, I go for slow-release granules.

I also check whether I am feeding indoor plants, outdoor plants, or a garden bed, since that affects what works best.

What I Look for on the Label

I always read the label carefully. I look for:

  • Clear NPK ratio of 10 10 10
