How to Apply
-General application: 2–3 lbs per 100 sq ft
-Established beds (spring): 2–3 lbs per 100 sq ft, before spears begin to emerge
-Post-harvest: 1–2 lbs per 100 sq ft after the final harvest, as ferns begin actively growing
Timing:
-Early spring: just before spears emerge, so nutrients are ready as growth starts
-Post-harvest (late summer/early fall): as ferns grow and refill the crowns for next season — if you feed only once, choose this one
Steps:
1. Broadcast evenly over the root zone, starting at the crown and extending 2–3 feet on both sides of the row — asparagus roots spread wide.
2. If the bed is mulched, pull the mulch back, apply, then replace it after watering in.
3. Water thoroughly after application to move nutrients into the root zone and start the microbial breakdown.
4. Feed twice a year (early spring and post-harvest); if only once, choose post-harvest to rebuild the crowns.
When and how often: early spring (pre-spear) and after the final harvest (fern growth); post-harvest preferred if feeding once.
What NOT to do: do not cut the ferns down early (they're feeding next year's crowns — let them stand until they yellow), do not over-apply on shallow roots, and do not leave it surface-exposed where pets can reach it.
