more concrete block planters :
site prep
molds set off-center to adjust to alternate pattern(which adds stability) of block layout.
to seal the holes of top blocks, pour a bit of cement over a sheet of plastic
the blocks inverted
slather the tops and sides with tan concrete icing to finish the cake, then stuff the void with as much organic matter(weeds/thorny brambles/twiggies/kitchen refuse). Economical since it fills the bottom and skimps on having to buy extra soil-mix bags to be used as topsoil
then top it off with friable soil mix and drench with water to percolate downwards and fill empty packets.
the final products with lemon grass, okra, egyptian spinach, and mexican green onions/chives
