Proven Winners® Premium All Purpose Potting Soil
Proven Winners Premium Potting Soil is a professional grade soil for homeowner use made from a blend of composted bark, premium Canadian Sphagnum peat moss and horticultural grade perlite.  The product comes in two sizes – a 1.5 cu. ft. bag, which is perfect for outdoor container use, and a 16 qt. bag, perfect for indoor use and for smaller outdoor containers.

The 1.5 cubic ft. bag comes premixed with Proven Winners 15-7-15 + Minors Premium Continuous Release Plant Food, which provides a continuous nutrient release to help ensure consistent feeding while providing a base level of nutrition.  Both the 1.5 cu. ft. and 16 qt. sizes contain dolomite lime to buffer soil pH, and a wetting agent for thorough water distribution.  

The result is a medium weight mix with excellent air porosity and drainage - all important features to give you the best growth and most vibrant, colorful flowers, and healthy vegetables.  Note – to achieve optimal growth results with both products, we recommend using Proven Winners Premium Water Soluble Plant Food every 1-2 weeks after planting.

Nut Allergies? All Proven Winners potting soil bags contain a statement that product may be produced at a plant that uses composted nuts, however, this is a regulatory requirement. We do not use any nut compost at any of our production facilities and the ingredient statement on the back of the bag says this product includes: Sphagnum peat Moss, Composted bark, Perlite and fertilizer ingredients. Additionally, no compost is not used.

It is critical for you understand the importance of regular feeding of your plants! Just like people – your flowers need food and water to provide you with constant color!  When growing plants in containers, the food must be added to the container or basket since the plant has no other way to get nutrients. Our mix in water fertilizer can be added each time you water your plants, it provides all the necessary nutrients to keep your plants going strong.

Designed with the lazy gardener in mind, our Continuous Release Plant Food provides all the same nutrients but in granular form so you only need to apply once or twice each season! One application every six months is all you’ll need as our plant food delivers nutrients only when the weather is warm and plants are actively growing. It won’t waste plant food during cold months when plants don’t need it.
