Soil in a raised bed |
2018-06-24 |
|
Georgia pose la question :
Good Afternoon,
I'm planning on building a raised bed garden measuring
6 feet long x 4 feet wide x 12 inches deep.
I'm not sure how to calculate the amount of soil to fill it up. I will have to
purchase the soil in 2 cubic feet bags.
I've read several articles about this topic on various gardening websites,
and one of them stated it would take a ton of soil to fill up an 8 foot long x
4 foot wide x 12 inch deep raised bed garden.
I'd greatly appreciate it if you could help me out with this quandary.
Thank you for your prompt and courteous response.
Kind Regards,
Georgia
