Asparagus is a long-game crop: the spears you cut in spring are powered by energy the plant banked in its crown the previous summer. That makes the post-harvest fern a feeding priority, and it's why this formula leads with nitrogen — 16% — to drive the lush fern growth that recharges the crown for next year, alongside 10% phosphate for roots and crown establishment and 13% potash for plant structure and resilience. Added sulfur and magnesium round it out, with magnesium feeding the chlorophyll that keeps the ferns green and photosynthesizing hard.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 6.0pt;\"\u003ePart of the nitrogen comes from polymer-coated urea, which releases gradually rather than all at once — so a single post-harvest application keeps feeding the ferns through their growing stretch instead of flushing and fading. The timing is the key: cut your spears through spring, stop harvesting, then feed, and let the ferns convert that nitrogen into stored crown energy all summer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHigh nitrogen, on purpose — \u003c\/b\u003e16% nitrogen drives the post-harvest fern growth that recharges the crown — and next spring's spears are made from this summer's stored energy.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePartly coated, longer feeding — \u003c\/b\u003ePart of the nitrogen is polymer-coated for gradual release, so one post-harvest feeding keeps the ferns fed through their growing stretch.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMagnesium for green ferns — \u003c\/b\u003eAdded magnesium feeds the chlorophyll that keeps ferns green and photosynthesizing — directly tied to how much energy the crown banks.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eA complete perennial feed — \u003c\/b\u003eSulfur supports nutrient uptake; 10% phosphate builds roots and crowns; 13% potash supports structure and resilience in a long-lived bed.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNew beds to old beds — \u003c\/b\u003eNew crowns or decades-old beds, small raised beds or large patches — one formula for the whole asparagus life cycle.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSimple bed rates — \u003c\/b\u003e1.5–2 lbs per 100 sq ft; a 5 lb bag covers roughly 250–333 sq ft.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 6.0pt;\"\u003e\u003cstrong\u003eWhere to use it:\u003c\/strong\u003e new asparagus crowns and established beds, small raised beds and large perennial patches, in home gardens and larger plots.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Old Cobblers Farm","offers":[{"title":"5 lbs","offer_id":41560553259141,"sku":"C8-7D4N-95CK","price":30.99,"currency_code":"USD","in_stock":true},{"title":"10 lbs","offer_id":41560553291909,"sku":"6J-OYZT-I7XO","price":34.99,"currency_code":"USD","in_stock":false},{"title":"15 lbs","offer_id":41560553324677,"sku":"7M-N40R-A4HA","price":39.99,"currency_code":"USD","in_stock":true},{"title":"20 lbs","offer_id":41560553226373,"sku":"3B-2FUM-GKB7","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/3573\/9781\/files\/OldCobblersFarm_WickedGrowthAsparagusFertilizer.jpg?v=1774850958","url":"https:\/\/theoldcobblersfarm.com\/products\/https-theoldcobblersfarm-com-products-old-cobblers-farm-wicked-growth-asparagus-fertilizer-_pos-1-_psq-asparag-_ss-e-_v-1-0","provider":"Old Cobblers Farm","version":"1.0","type":"link"}
