I love all this talk of new garden installation! Just yesterday I constructed and filled a 4x12x12 bed. I used 1/2 black dirt and 1/2 composted manure on top of logs from the forest. I also mixed in some aged alpaca manure with straw. Soon I will add a huge ( up past my waist) of perlite and vermiculite. These help with drainage.
I will top it off with shredded leaves.
I am also interested in seed swapping
