Re: Peat Moss as a Soil Ammendment?
You're in Ventura ... I believe you have the tidal clay? Peat Moss will help keep your soil on the acidic side for 3 to 5 years, and much longer if you keep your water supply from being alkaline.
I'm hoping you added horticultural sand. The "playground" sand sold in bulk is usually treated with herbicides and sometimes insecticides too. The dust material in horticultural sand is beneficial to plants. Another good choice is common 3/8 inch gravel (in moderation).
