How Many Bags Of Compost Will I Need

Question

I’m making Mels Mix. I have the peat moss and vermiculite. I’m just not quite sure how many bags of compost I’ll need. I have three 4’ x 8’ and five 4’ x 4’ beds. All are 10” deep. I’ve come up with three different choices. 33? 44? 55?

Answer 1

The proportion is equal parts (1/3 each) of peat moss, vermiculite, and compost. So the amount of compost would be the same as the amount of peat moss and vermiculite you figured. Plus it depends on the size of the bag as to how many you will need.
