Frequently Asked Questions (FAQs)

1. What is the best fertilizer for garden plants?

Most gardeners should use a complete fertilizer with twice as much phosphorus as nitrogen or potassium. An example would be 10-20-10 or 12-24-12. These fertilizers usually are easy to find. Some soils contain enough potassium for good plant growth and don't need more.
