-Extend established garden
-Open new ground for first time garden
1- Spread mulch, fertilizer or other additives before I arrive to till.
2- Mark any sprinkler line or other obstacles before I arrive to till.
3- Call bluestakes prior to tilling for a new garden. (Cable lines can be very shallow)
4- New ground can be quite hard. Getting the ground very wet the day before tilling (without making it a mud bog) will allow the tiller to get deeper. Sometimes it takes a year or two of growing and tilling to get a down 6" to 8"
Old plants/ Overgrowth
Old plants and other growth can be tilled in however, this can cause seeds to be pushed underground making it more difficult to control new weed growth.
