Raised Bed Vegetable Garden with Stone Borders

It's taken me all summer to get to it but I'm finally taking the first steps toward changing the vegetable garden to the parterre layout. I had some of the blocks sitting around for months now and others I borrowed from our patio sidewalk expansion which I just haven't had time to get to this summer.  Using the stone for the border is more expensive than wood but will last much longer.  

For a comparison take the $2.50 cost per foot of these stone blocks and compare it with a piece of lumber somewhere around $5-6 for a 10 foot piece.  That comes to about $0.50-$0.60 per foot which makes the stone about 5 times more expensive.  The big advantage is that it won't ever rot and it looks pretty good!

So far I only have one small portion of the raised bed vegetable garden put together.  Even it still needs several more blocks placed to complete the beds.   These beds are going to be planted ASAP with some more winter greens.  Pak choy sounds good and maybe more spinach.

Ever tried potatoes in the fall?  This one was a volunteer in a large nursery pot I was using for a weeding bucket.  I'm tempted to wrap the top area where you see the metal stakes in plastic to create a little greenhouse effect. I'm theorizing here but I might just be able to get some potatoes by December.  We'll see!  The neat thing about potatoes in a pot is that when they are ready all you need to do is dump the pot to get the potatoes.

How's your vegetable garden growing?
