mel's mix calculator

Welcome to the ultimate tool for Square Foot Gardeners! If you're embarking on the rewarding journey of square foot gardening, you've likely heard of "Mel's Mix." This specially formulated soil blend is the cornerstone of Mel Bartholomew's revolutionary gardening method, promising optimal growing conditions for a wide variety of plants.

But how much do you need for your specific raised bed? And what are the precise quantities of each component? Our Mel's Mix Calculator is here to take the guesswork out of the equation, ensuring you get your garden off to the perfect start.

What is Mel's Mix? The Perfect Growing Medium

Mel's Mix is a proprietary soil blend designed by Mel Bartholomew, the creator of Square Foot Gardening. Unlike traditional garden soil, which can be heavy and prone to compaction, Mel's Mix is light, fluffy, and nutrient-rich. It promotes excellent drainage while retaining moisture, and its loose structure allows roots to grow freely, leading to healthier, more productive plants.

The Golden Ratio: 1/3, 1/3, 1/3

The magic of Mel's Mix lies in its simple yet effective recipe:

• 1/3 Coarse Vermiculite: This lightweight, expanded mineral acts like a sponge, holding moisture and nutrients while simultaneously improving aeration and drainage. It prevents compaction and keeps the soil structure loose, which is vital for root development.
• 1/3 Peat Moss (or Coco Coir): Peat moss is excellent for retaining moisture and providing a slightly acidic environment that many plants love. For an environmentally friendlier alternative, coco coir (made from coconut husks) offers similar benefits, improving water retention and soil structure.
• 1/3 Blended Compost: This is arguably the most crucial component. Mel Bartholomew strongly advocated for using at least five different types of compost. Why? Each type of compost brings a unique blend of microorganisms and nutrients to the mix. A diverse compost blend ensures a wide spectrum of essential nutrients and beneficial microbes, creating a robust and healthy ecosystem for your plants. Examples include mushroom compost, worm castings, leaf mold, aged manure, and homemade vegetable compost.

Why Use the Mel's Mix Calculator?

Sourcing Your Ingredients

Quality Matters

When sourcing your ingredients, prioritize quality. Look for coarse-grade vermiculite, not fine. For peat moss or coco coir, ensure it's horticultural grade. For compost, seek out reputable suppliers or make your own. Remember, the diversity of your compost blend is key!

Where to Buy

• Garden Centers: Most garden centers will carry vermiculite and peat moss/coco coir.
• Bulk Landscape Suppliers: For larger projects, buying in bulk can be more cost-effective for compost and sometimes vermiculite.
• Online Retailers: A good source for specific types of compost or larger quantities of vermiculite.
• Local Farms/Nurseries: Often have high-quality compost available.
