What's my favorite soil? 

This one!

Especially blended for containers, this soil offers excellent aeration and drainage with the addition of pumice. Pumice aids in drainage, and with its microscopic holes, it helps retain minimal moisture levels. This is a lightweight soil mix that promotes root growth.

This soil has particular success with plants that are moisture sensitive and reduces the chance of root rot from plants sitting in poorly draining mixes.

Additional pumice can be added to the mix if your climate is high in humidity for additional drainage.

I was told it looks like fancy coffee packaging. I will be offering it in Venti and Grande Sizes.

Venti Appx 20 oz and enough for roughly 3 4" potted plants

Grande Appx 32 oz and enough for roughly 5 4" potted plant
