I am lucky , these are sprouting containers setting on a 8 inch raised bed ,, Forest like ,,
That is , as it began , two or three seasons , of every kind of mulch and leftover potting mixes ground up and piled up and dug in ,
The one across from this is twice as long and has three to four feet deep of forest like top soil all nice and dark looking ,easy to dig in . and full of worms ,,
Saying compost and mulch , is only a polite of a graphic way of saying a dessicated and "poop" load of work and effort ,, (done over time , not so bad though
I forgot, that is the result since 2003 , I occasionally do the stack , mix , fork over a few inches ,
