Concrete Tree Ring Raised Planter for Daylilies. 9.18.15

 This is the "Tree Ring" planter I put together over the past couple of weeks for some daylilies.  This is a spot that I often drag the garden hose across, damaging plants.  The planter will stop the hose from causing damage.  The planter is raised, which is nice for an old guy  to weed and trim the plants.  About the same size as a half wine barrel.  Especially since I had them sitting around.  This is between a container and a raised bed, in concept.

I leveled the ground for the base.  Arrange first ring, right side up.  Arrange second ring upside down, so the scalloped edges mesh.   Arrange the top level right side up again.

I mixed together yard soil with about 1/4 kitchen compost.  The yard soil is mole hills that I collected in the wheelbarrow.  The soil is finely ground, and taken from deep under my yard.  My soil tests low in magnesium and calcium, so I added about 1/4 cup of lime and 1/8 cup of Epsom salts.  Not rocket science, did not use a measuring cup.  I saved some coffee grounds, added about 4 cups of those for ongoing organic matter and nitrogen.

The daylilies were from other parts of the border where they were difficult to see and difficult to weed.  I wanted one bigger one - the maroon, almost coffee-brown one with darker eye, no name other than "Vigaro" from Home Depot.   The other two were incorrectly labeled or mutant, a very compact, very light yellow and taller, finer sort of apricot pink.  All of these will be easier to view and enjoy at this higher level, about 18 inches higher than the garden border.

I filled soil to the point where I could set in the daylily clumps on the soil.  Between the daylilies, I set hyacinth bulbs and pushed into the soil slightly  Those will have roots deeper than the daylilies.

Then I filled in the rest of the soil, watered in, and mulched with chipped tree trimmings.  Almost no transplanting trauma to the daylilies,  I imagine they will need dividing in one or two years.  No problem.

I saw some of these tree ring sections on the web for about $4.00 each.  That would make it $36.00 if I bought them new, roughly the same as a half wine barrel.  I think I bought them on sale a few years ago for about half that.  They should lase a lifetime.  A half wine barrel seems to last about 10 years in this rainy Pacific NW climate.  Compared to a wine barrel, the rings are easier to carry, can just carry one at a time.  I don't know about insulating properties.  Might not be as good as wood.
