That’s how I do my garden. Started with cardboard over grass double layered then 10 cubic yards of compost on top, at least 3 inches of new compost on each row. Each succeeding year i layer leaves from the year before (2 huge compost piles out back I save them all) then in the spring I put in the leaves and compost as soon as it’s availabe in bulk (local company does organic dark leaf compost nothing else in it) it’s a bit more expensive but you don’t have to add any ferts all season, I just hit the garden with an hour of water every morning.It may be bro science to some and you may bring in a straggler or three in terms of pests but if you are an organic grower, you should look into using leaves and whether it helps you achieve a cheaper and better method than without. Leaves are easy to come by. Pile em up and spread manure/dirt over top. Plant a few months later.
Taking a Closer Look at Tannins
If it worked for every veggie in that garden (at least 30 varieties lol) I bet it would do awesome on my outdoor plants next year
Awesome way to grow organically, not to mention the cardboard the first year kills all the weeds (at least 90%) so weeding was about 10 minutes every few days in a 65x40 garden
