Seems like everyone is talking about no-till gardening these days. This is the idea that if you inoculate your soil with bacteria and-fungi and layer enough enough compost and “duff”on the surface, that you can recreate the forest floor and avoid the tedium of digging our heavy East Bay clay.
While sheet composting, straw mulching and shallow surface cultivation will work in the long run, it may not be the perfect choice for those who wish to garden in well amended clay soil in the next five years. An integrated system of sheet composting, double digging, single digging and amending with compost for the first few years will decrease the amount of time it takes to achieve an effective no-till system.
Here is a sample scenario:
Year 1: Sheet mulch.
Year 2: Double dig. add compost and green manures, mulch with rotted straw, aged manures or other easily decomposable material.
Year 3 & 4.: Double or single dig with green manures or finished compost, mulch tops of bed with rotted straw, aged manures or other easily decomposable material.
Year 4 or 5: Start no-till gardening, continue to layer mulch on top of beds at each planting.
