GardenPRO Muriate of Potash is a GardenPRO muriate of potash potash fertilizer designed to supply potassium for plant strength and season-long performance in home gardens. This potassium fertilizer is a focused plant nutrient for growers who want a simple, single-purpose potash source.
Muriate of potash is often chosen as a plant fortifier when the goal is a cleaner, sturdier-looking garden through spring, summer and fall, while also supporting winter hardiness going into colder weather. Instead of positioning itself as a broad “all-purpose” blend, this product keeps the intent narrow and easy to shop: potassium-forward nutrition that helps plants stay resilient during typical seasonal stress.
Because it’s purpose-built around potash, GardenPRO Muriate of Potash fits gardeners who already have their base fertility handled and want a targeted boost to overall plant condition. It’s also a sensible pick for landscapes and beds where you’re trying to support stronger structure and steadier performance across the season, rather than chasing short-lived changes. If your plants look fine early on but fade as the season wears on, a potassium-focused potash fertilizer is often the missing piece in a simple nutrition lineup.
Facts layer, kept compact: this product carries a 0-0-62 NPK, which identifies it as a high-potassium fertilizer with no nitrogen or phosphate listed in the analysis. The key input is potash (potassium), positioned as a direct, readily available potassium source for gardeners who want a clear, easy-to-understand role in their program.
GardenPRO Muriate of Potash is a good fit for home gardeners looking for a muriate of potash plant fortifier that supports winter hardiness and helps keep plants looking strong through spring, summer and fall, with a straightforward high-potassium 0-0-62 profile.
Apply: Mix 250 g (1/2 lb) per 10 m² (100 sq. ft.) of soil.
How: Spread evenly, work it into the soil, then water thoroughly to help it move into the root zone.
