Commercial potting mixes are convenient, but most are nothing more than sterile dirt (likely treated with chemicals to eliminate weeds and pathogens). Instead of mineral-rich soil, they are mostly bark, peat or coir—light enough to transport, but lacking in the essential minerals and trace elements that produce lush, fragrant flowers and nutrient-dense food.
For the most beautiful blooms and the healthiest plants, container gardeners should start with a high-quality organic potting soil and amend it with mineral-rich rock dust. A product like Cascade Minerals Remineralizing Soil Booster that is made of all-natural volcanic basalt will steadily release calcium, magnesium, iron, manganese and silicon dioxide into the soil while helping improve water retention.
Finely milled volcanic basalt is well-suited to the needs of most container gardeners because it produces relatively little ambient dust and is easy to add to container mixes. Moreover, a little goes a long way. A small quantity of high-quality volcanic basalt is all it takes to provide container plants with the essential minerals and trace elements they need to stay strong, healthy and resistant to disease.
Need some container inspiration? Try these tips:
- Start with a sturdy container that will take you through different seasons and can accommodate different styles
- Make sure your containers have drain holes before you begin filling them (and look for the “perfect spot” while they are still empty)
- Reduce the weight of a large container by filling the bottom half with lightweight materials (anything from Styrofoam peanuts to pine cones to inverted plastic pots)
- Don’t skimp on plants—for a lush container that shines all season long, choose a dramatic mixture of “thrillers, fillers and spillers”
- Keep things fresh by replacing wilted plants with new ones
- Keep containers well-watered (water when surface soil is dry to the touch)
