Bone meal is a high-phosphorus, low-nitrogen amendment — the right tool when you want root and tuber development without pushing leafy growth.
 
For potatoes: phosphorus supports tuber formation; excess nitrogen works against it. Work 2–3 tablespoons into the soil below each seed potato at planting. One pound covers roughly 5 lbs of seed potatoes.
 
For asparagus: phosphorus supports the deep root establishment that makes asparagus a 20-year investment. Work 2–3 tablespoons per crown into the bottom of the planting trench.
 
For bulbs: a tablespoon in the planting hole for tulips, daffodils, camas, and other bulbs supports root development through fall and winter.
 
For transplants: a small amount in the planting hole at transplant time reduces shock and supports establishment.
