Soil & Amendments Buying Guide

Understanding Soil Components

Quality growing media combines organic matter, minerals, and air pockets. Our guide helps you understand the components and choose the right blend for your specific gardening needs.

Types of Amendments

  • Potting Mix: Pre-formulated blends for containers, often including perlite or coir
  • Compost: Decomposed organic matter rich in nutrients and beneficial microorganisms
  • Mulch: Surface covering that retains moisture and regulates temperature
  • Aerating Agents: Perlite, vermiculite, and pumice improve soil structure

Best Practices

  • Replace 25-50% of soil annually to maintain nutrient levels
  • Mix amendments based on your plant’s specific requirements
  • Test soil pH before adding buffers
  • Store soil in cool, dry conditions to prevent compaction

Container Garden Recommendations

For urban container gardens, we recommend a 40% potting mix, 30% compost, 20% coir, and 10% perlite blend. This provides excellent drainage while retaining necessary moisture and nutrients.
