Frequently asked questions

Q: What’s the difference between fertilizer and amendment?
A: Fertilizers feed plants (N-P-K + micronutrients). Amendments improve soil structure, biology, and long-term performance.

Q: Can I apply compost and fertilizer together?
A: Yes—compost supports soil health; fertilizer provides targeted nutrition. Just follow label rates to avoid overfeeding.

Q: How often should I fertilize?
A: Depends on product type and plant needs. Slow-release is usually less frequent; liquids may be more frequent but lighter doses.

Q: I see yellow leaves—what should I use?
A: Often a nutrient availability issue (commonly iron in high pH soils). Consider a micronutrient option and check watering/drainage.
