Rolling hills. A few rocky areas. Some side-slope where it’s too narrow for a tractor.
Handheld gas-powered weed wackers used just after weeds germinate
Gramegna tractor-mounted in-row tiller. Challenges: Slow & one-sided
Piloting a few weed-trimmer attachments
1 - 2 passes depending on growing season conditions

Hire sheep before bud break (Kaos)
Currently, some blocks are no-till and some alternate till. Goal to be entirely no-till. Even in a dry year we didn’t see a drop in yield in no-till blocks.
Some of the very aromatic we don’t want in the fruiting zone (e.g., hit Mare’s Tail with a targeted shovel pass). Johnson grass - tall, vigorous and deep-rooted - do worry about competition.
Fair tolerance for weeds in the vineyard. Mostly dead or dormant for core vineyard management. Some dead/dormant weeds are also shading out further weed growth.
