Is it safe to use wooden pallets for a raised bed? I got a bunch from a lumber company that I'm wondering what to do with. I plan to use 4 to create a compost box, but don't know what to do with the others.

If planning on using the pallets for edibles, the wood must not be treated. Find out of the pallets are made of untreated or treated lumber.

Thanks for the info. I'll check on that!

How about some big plastic barrels from restraunts--I have two white ones that had olive oil in them The size of water barrels. I cut them the long way and then put them on stands. My mother has a big barrell also cut in two. It is waist high and she doesnt have to bend. She has carrots-onions an tomatoes in it. As I get older I want to have raised all over. cathy

Have you considered NOT putting sides on your riased beds, but just mounding the dirt and planting in it like hilling in?

Or how about finding someone dumping old straw or hay bales and use them as edging? Or planting directly into the bales...?

Raw lumber from a mill, or the slabs. You really don't need a finished edge, you just want to keep the dirt from washing away, right?

I am wonering if the roots will get torn up on all that rubble. I also wonder if some one might get hurt, walking on the rumble, or digging in it.

Katie,

If you want some rocks to use as edging and live near Indianapolis, email me.

How big are the mulberry trees? (if they're still there, it's been a while since this topic started) I used a lot of the limbs from my maple tree as edging for gardens and flower beds. They'll have to be replaced in a few years, but I love the look. AND they'll break down into compost eventually!

I have cinder blocks around my raised beds. If you have them in your soil already you should dig them out and use them. But I'd get rid of any glass. Cheryl
