It is not an N-P-K fertilizer — it is a targeted supplement for two essential nutrients plants can't make leaves and proteins without. Magnesium sits at the center of every chlorophyll molecule, so a shortage shows up as a telltale pattern: interveinal chlorosis — yellowing between the veins of older leaves while the veins stay green. Sulfur backs the amino acids and enzymes behind healthy growth.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eGreens up deficient leaves — \u003c\/b\u003eMagnesium is the core of chlorophyll — correcting a shortage restores green color and reverses the interveinal yellowing of older leaves.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMagnesium AND sulfur — \u003c\/b\u003eTwo essential nutrients at once: magnesium for photosynthesis and sulfur for the amino acids and enzymes behind healthy growth.\u003c\/p\u003e\n\u003cp\u003e\u003c!-- [if !supportLists]--\u003e\u003cb\u003eWorks fast, applies any way — \u003c\/b\u003eFully water-soluble, so it dissolves for foliar sprays and drenches that act within days — or mixes dry into soil.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMade for Mg-hungry plants — \u003c\/b\u003eThe trusted fix for tomatoes, peppers, roses, and blueberries, and for the sandy, high-potassium, or rain-leached soils that lose magnesium fastest.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePure and predictable — \u003c\/b\u003eA single defined compound with guaranteed minimums that match the chemistry — no guesswork, no fillers.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"mso-list: Ignore;\"\u003e\u003cspan style=\"font: 7.0pt 'Times New Roman';\"\u003e \u003c\/span\u003e\u003c\/span\u003e\u003c!--[endif]--\u003e\u003cb\u003eOrganic or conventional — \u003c\/b\u003eSuitable across organic and conventional programs as a clean, targeted nutrient source.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 6.0pt;\"\u003eBecause it's fully water-soluble, it works fast and flexibly: mix it into soil at startup, dissolve it for a foliar spray that greens leaves within days, drench the root zone, or run it through fertigation. It's the classic fix for magnesium-hungry favorites — tomatoes, peppers, roses, and blueberries — and for the soils that lose magnesium fastest: sandy ground, high-potassium soils, and beds leached by heavy rain. The honest caveat that keeps it credible: magnesium sulfate corrects a magnesium (or sulfur) deficiency. Where there's no deficiency, more won't help — so a soil test or the clear interveinal-yellowing symptom should guide its use.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 6.0pt;\"\u003e\u003cstrong\u003eWhere to use it: \u003c\/strong\u003evegetables (especially tomatoes and peppers), roses and flowering ornamentals, evergreens and acid lovers, fruit trees, lawns, containers and houseplants, and any magnesium- or sulfur-deficient soil — across organic and conventional programs.\u003c\/p\u003e","brand":"Old Cobblers Farm","offers":[{"title":"5 lbs","offer_id":41560544477317,"sku":"AE-G3VL-LUKM","price":44.99,"currency_code":"USD","in_stock":true},{"title":"10 lbs","offer_id":41560544411781,"sku":"D4-VZU4-9IG7","price":62.99,"currency_code":"USD","in_stock":true},{"title":"15 lbs","offer_id":41560544379013,"sku":"FO-2WXY-8B1P","price":82.99,"currency_code":"USD","in_stock":true},{"title":"20 lbs","offer_id":41560544444549,"sku":"Z9-T094-3YP2","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/3573\/9781\/files\/OldCobblersFarm_WickedOrganicsMagnesiumSulfate.jpg?v=1774863458","url":"https:\/\/theoldcobblersfarm.com\/products\/https-theoldcobblersfarm-com-products-old-cobblers-farm-wicked-organics-magnesium-sulfate-_pos-1-_sid-18a2dee7b-_ss-r","provider":"Old Cobblers Farm","version":"1.0","type":"link"}
