What Daniel Covers

Daniel covers the diagnostic side of GreenOurs: pest identification, disease symptoms that look alike, watering and soil, and tools and equipment. His articles often pair two look-alike problems (shore flies vs. fungus gnats, bacterial vs. fungal leaf spot) so readers can tell them apart before treating.

How Daniel Approaches His Articles

Each diagnostic piece starts from the visible symptom, because that is what a reader is looking at. Likely causes are ranked by probability rather than listed with equal weight, and simple fixes (such as adjusting a watering schedule) are separated from cases that warrant a professional opinion. Product and technique claims are checked against manufacturer specifications or extension guidance, and guides are reviewed and updated as information changes.
