large container 'ballast'
Hi, I have very deep raised beds...20"...and will be moving them soon. I figure it's my chance to use some ballast this time and have the leftover soil to use elsewhere. I have seen the comments about using milk jugs etc but I don't have a supply of those. Has anyone used perlite...I can get it cheap...or large chunks of styrofoam with success? The styrofoam would still allow soil to contact the ground but the perlite would not. Can anyone see a problem with these idea's?
