Best Fall Fertilizers for Your Garden: Expert Recommendations and Dosages

Plants may slow down in winter, but soil life like earthworms and microorganisms stays active—if properly fed. Fall fertilization nourishes them through the cold, ensuring steady nutrient release come spring. Not all organics work the same; here's what experienced gardeners recommend.

Choose high-quality organic matter that decomposes slowly for optimal results. Dosages are per 10m²—a standard garden plot size.

Top Fall Fertilizer Options

  • Manure: 2 to 3 kg per 10m²
  • Wool and feathers (from discarded mattresses and pillows): 2-3 kg per 10m²
  • Crushed or roasted horn: 300 to 400 g per 10m²
  • Wood ash: Bury in top 10 cm at 500 g per 10m²
  • Lithothamnium: 300 to 500 g per 10m² (ideal for acidic or neutral soils)
  • Garden compost: 50 to 80 liters per 10m² (roughly one wheelbarrow)

Save fast-acting boosters like guano and desiccated blood for spring use.

Visualizing 10 m²:

  • 10m x 1m rectangle
  • 5m x 2m rectangle
  • 3.33m x 3.33m square
