User Question: Every year, I battle mites on my tomatoes. I prefer avoiding chemicals—what are my options?
As seasoned gardeners know, spider mites thrive in hot, dry conditions, forming swarms on tomato plants. These tiny arachnids—often called red spider mites (from the French araignée rouge)—can appear yellow, green, or red depending on the species. Don't worry; effective organic treatments exist based on years of practical experience in home gardens.
The gold standard is sulfur powder, dusted directly on plants for superior control. Wettable sulfur (mixed with water and sprayed) offers moderate results. For additional natural options, try sprays from fern decoctions or nettle manure, which have consistently protected crops without harm.

Increase humidity to deter them by spraying the undersides of leaves with a high-pressure garden hose or sprayer—this simple, trusted technique washes them away effectively.
Key Reminder: Insecticides are useless against spider mites, as these pests are arachnids, not insects. Stick to targeted, spider-specific remedies for reliable results.
