Maybe
you don’t even have an “outside” - or physical limitations, or lack of sturdy
and willing helpers have kept you from considering growing your own food. Two solutions:
Lasagna gardening - This method of making garden beds requires no strenuous digging at all - it utilizes the natural action of microbes to form productive soil where there previously was none. The principal is to allow Nature to make and keep soil in the condition it’s normally found: undisturbed and covered with a layer of decomposed organic material. If you have a patch of lawn that you would like to turn into a garden, or perhaps a persistently weedy section of your property that takes ‘way too much time to maintain, this is the method for you. By not rototilling or digging in the ground, weed seeds are left undisturbed so they are not brought up to the surface to germinate. Place layers of scrap cardboard or clean newsprint on the mowed ground (clippings left where they are), cover with a thick layer of organic mulch - wood chips, decomposed leaves, grass clippings, unfinished compost, or my favorite, animal manure mixed with bedding. (If you have a neighbor with livestock or chickens, start cultivating that friendship!) Don’t layer grass clippings thickly - mix with chopped leaves, rotted straw, manure etc. to add loft to the mix so it doesn’t compact. Leave the mulch in place to decompose, ideally over a complete season, but depending on what mulch you use, you may be able to plant in just a few weeks (I have used a couple bags of purchased soil mix over the mulch layer, letting the plants find the rich nutrients below while they grow). A substrate of rich compost will form over time, the bottom layer suppressing grass and weeds. Thus this method also overcomes the limitations of poor or clay soil. With minimal maintenance you will have a planting area needing only an annual cover of mulch to restore. After the first year, avoid deep soil disturbance and use organic materials as mulch for your plants to keep weeds from germinating. Much more on this method is available online.
