Hello,

Im brand new to EarthBoxes and I just finished setting up my two boxes before I saw this thread!  Now Im worried that I used the wrong mix... I filled up with "Great Gardens" garden soil, which is 40% composted manure, 40% leaf compost, and 20% sphagnum moss.  Will this wick poorly or drown my plant roots? Can I amend it by mixing with perlite or vermiculite? And if so, do I need to dig out all the soil, including the fertilizer strip and dolomite, or can I just mix it down to the dolomite layer? 

Thanks!


No, Its wrong for the Earthbox science. Wicking is really the only purpose for the pmix other than a place for roots.

Peat, no manure, top soil of any kind. It will fail your efforts. Compost does not belong in your Earthbox. Your making it an expensive planter. The EB must wick. "Great Gardens" garden soil, which is 40% composted manure, 40% leaf compost, this will rot and interfere with wicking and air spaces are wiped out.
