s/h scaffold boards also - gd to know they're cheap.

For bed height 6" (a different notion of 'raised bed') we use sawmill 'slabbing' or 'scantlings' - the outer bit with bark, resiny doug fir at our local mill, 7" to 9" wide, lasts 3-4yrs, looks good, easily renewed. Treated 38x38x450 pegs @ 600c/cs. On cross-sloping ground, can make terrace-retaining walls 500h even, 3 boards high, with 50x50x750 pegs @ 400c/cs - surprisingly durable. I made a miniature post-thumper - 6" of 2" pipe with plate welded across end, slips over top of a peg, can be bashed with lump or sledge hammer without splitting.]]> Raised planters - best material to use https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17455&Focus=295955#Comment_295955 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17455&Focus=295955#Comment_295955 Sat, 23 Apr 2022 08:44:42 +0100 philedge Posted By: djhI can see that will restrain the corners but do they still bulge a bit along the middle of the beds?

Primarily to keep the corners tight so soil doesnt drop out. Longest run we have is 6 x 2'6"×2' and theres no significant bulge in the middle with them set a foot in the ground longer side down.]]> Raised planters - best material to use https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17455&Focus=296016#Comment_296016 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17455&Focus=296016#Comment_296016 Tue, 26 Apr 2022 10:16:16 +0100 Jamster
The recycled plastic boards are I suppose ticking a box but they're expensive!

If you're just doing v shallow raised beds, do you need them - look at Charles Dowding's website / you tube. He recommends not using them if you go down the no-dig route. Be warned though, its quite a rabbit hole!]]>
