As the days shorten and temperatures drop, your plants are shifting gears. Growth slows, energy redirects to the roots, and nutrient uptake changes — but that doesn’t mean feeding stops. In fact, trace elements (also called micronutrients) become even more important in fall.
What Are Trace Elements?
Trace elements are the “behind-the-scenes” nutrients that keep everything running smoothly. They include iron (Fe), manganese (Mn), zinc (Zn), boron (B), copper (Cu), and molybdenum (Mo) — all needed in small amounts but critical for plant function. Without them, plants can’t efficiently use the nitrogen, phosphorus, or potassium from regular fertilizers.
Think of trace elements as the spark plugs that keep the engine firing — without them, the system stalls.
Why Fall Feeding Matters
When fall arrives, plants slow their top growth but ramp up root development and carbohydrate storage. This stage sets the foundation for healthy spring growth. Feeding trace elements now helps plants:
- Correct minor deficiencies before winter dormancy
- Strengthen roots for better cold tolerance
- Keep leaves active longer for late-season photosynthesis
- Store nutrients efficiently for next spring’s growth burst
For container fruit trees and berries, trace element supplements help reduce the yellowing and leaf drop that often appear as indoor light and temperatures change.
How to Apply Trace Elements in Fall
- Use a foliar spray or drench: Trace elements are absorbed quickly this way.
- Feed in mild temperatures: Early morning or late afternoon applications prevent leaf burn.
- Apply monthly through fall: Especially important for citrus, berries, and evergreens still holding foliage.
