- Plant Safety: Select non-toxic fertilizers safe for pets, beneficial insects, and pollinators to maintain a healthy garden ecosystem.
- Specific Plant Needs: Some fertilizers are tailored for tomatoes and vegetables specifically, optimizing nutrient delivery for these crops, while others offer versatility for various plants.
