Organic 4-6-4 with the Acid-Soil Micronutrients They Live On\u003c\/b\u003e\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 6.0pt;\" class=\"MsoNormal\"\u003eOld Cobblers Farm Wicked Organics Blueberry Fertilizer is a blended organic plant food formulated for blueberries and other acid-loving fruit and shrubs. Blueberries are famously particular: they want acidic soil (roughly pH 4.5–5.5), shallow feeder roots that spread well past the branches, and steady, gentle nutrition. This 4-6-4 is built around exactly that. Its nitrogen is split — of the 4% total, 2.5% is water-insoluble and released slowly by soil microbes, with 1.5% water-soluble for a steadier start — making it a genuine slow-release, non-burning feed safe for those sensitive shallow roots. The 6% phosphate supports root systems and flower-bud formation, and the 4% potash supports stress tolerance and fruit quality.\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 6.0pt;\" class=\"MsoNormal\"\u003eThe part that matters most for blueberries is the acid-soil package: it supplies iron, manganese, and sulfur — the micronutrients that become more available in acidic soil and whose lockup in sweet (high-pH) soil is the usual cause of yellowing leaves and weak growth. The elemental sulfur also works gradually to support the low pH blueberries need. One honest caveat keeps expectations right: blueberries are unusually pH-sensitive, and a fertilizer alone won't rescue genuinely alkaline soil — on high-pH ground, use a soil test and a dedicated acidifier alongside this feed.\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 6.0pt;\" class=\"MsoNormal\"\u003eIt's best fed in fall — blueberry roots stay active well into autumn, building winter hardiness and storing nutrients for spring — with a spring feeding before bloom for berry set. One ingredient note: this blend contains animal protein meals and bone char, so it is not a vegan product, and like other bone- and protein-based feeds it can attract pets; incorporate it and store it securely.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eThe blueberry micronutrients — \u003c\/b\u003eSupplies iron, manganese, and sulfur — the acid-soil micronutrients whose lockup in high-pH soil is the usual cause of blueberry leaf yellowing.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSupports blueberry soil pH — \u003c\/b\u003eElemental sulfur works gradually to support the low pH (≈4.5–5.5) blueberries need to thrive and fruit.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSlow-release, non-burning — \u003c\/b\u003eThe 2.5% water-insoluble nitrogen releases slowly through microbial breakdown — steady feeding that won't shock or burn shallow blueberry roots.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePhosphorus and potassium for fruit — \u003c\/b\u003e6% phosphate supports root systems and flower-bud formation; 4% potash supports stress tolerance and fruit quality.\u003c\/p\u003e\n\u003cp\u003e\u003c!--[endif]--\u003e\u003cb\u003eSupports bloom and berry set — \u003c\/b\u003eProperly fed plants in favorable soil set fuller bloom and better fruit — the feed does its part of the picture.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAll blueberry types \u0026amp; kin — \u003c\/b\u003eWorks for highbush, lowbush, and rabbiteye blueberries, plus azaleas, rhododendrons, and other acid-lovers.\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 6.0pt;\" class=\"MsoNormal\"\u003e\u003cstrong\u003eWhere to use it: \u003c\/strong\u003eblueberries (highbush, lowbush, and rabbiteye), plus azaleas, rhododendrons, gardenias, hydrangeas, heaths and heathers, huckleberries, mountain laurels, raspberries, and other acid-loving plants.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Old Cobblers Farm","offers":[{"title":"5 lbs","offer_id":41560547590277,"sku":null,"price":32.99,"currency_code":"USD","in_stock":true},{"title":"10 lbs","offer_id":41560547688581,"sku":null,"price":38.99,"currency_code":"USD","in_stock":true},{"title":"15 lbs","offer_id":41560547623045,"sku":null,"price":45.99,"currency_code":"USD","in_stock":true},{"title":"20 lbs","offer_id":41560547655813,"sku":null,"price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/3573\/9781\/files\/OldCobblersFarm_WickedOrganicsOrganicBlueberryFertilizer.jpg?v=1774862602","url":"https:\/\/theoldcobblersfarm.com\/products\/https-theoldcobblersfarm-com-products-old-cobblers-farm-wicked-organic-blueberry-fertilizer-_pos-1-_sid-e858556f5-_ss-r","provider":"Old Cobblers Farm","version":"1.0","type":"link"}
