Potatoes benefit from compost incorporated into the soil about 2-3 months before planting. Add a 3-4 inch layer of compost to the soil and work it in about 12 inches deep. Also, phosphorous promotes root growth. Organic sources are bone meal or rock phosphate. Or choose a synthetic fertilizer with a higher second number, i.e., 15-30-15, which indicates a higher percentage of phosphorous than nitrogen or potassium. Follow package instructions for amounts to apply. Good luck with your spuds!
