Potting Soil & Raised Bed Mixes for Boise Gardens

The first step in ensuring your plants are healthy and vigorous is rooting them in high-quality potting mix or amended soil.

For containers and hanging baskets, we recommend Fertilome’s Ultimate Potting Mix — a premium blend of peat moss and perlite designed for excellent drainage, moisture retention, and strong root development.

​

​Ideal Uses for Potting Soil

 

For in-ground beds and raised gardens, we always recommend incorporating organic compost to improve soil nutrient availability, increase water retention, and reduce compaction in Boise’s naturally dry soils.
