Five Simple Steps to Get the Most Out of Your Tertill

Using a solar-powered garden weeding robot can require some simple changes to your garden for optimal Tertill performance. Here are the top five: 


1. Size Matters - Each Tertill can patrol approximately 200 square feet, so a 10 x 20 garden, or 14 x 14 are great options. A well-tended 200-foot garden can out-produce a weed-filled, disease-ridden garden 2 times the size! 

2. Barrier - Tertill is programmed to roam, so it requires a physical barrier completely around the perimeter of your garden or else you will find it in your neighbor's yard!  The barrier should be at least 4-inches tall and preferably made of conductive materials such as:

  • Metal fence (chain-link, chicken wire, hardware cloth, etc.)
  • Wood fence (picket, stockade, landscaping timbers, wood planks)
  • Brick edging
  • Supplied row guards
Boundaries made of plastic, or other non-conductive material will contain Tertill but the robot will take extra time to turn around whenever it bumps into them. This uses up energy and can create ruts, so plastic is not recommended.

    3. Surface Prep - Tertill works best when the terrain is relatively smooth. Tertill has 4-wheel drive and will do its best to maneuver around rocks and ruts, but the time spent negotiating those is time away from weeding. A well-raked garden without rocks or ruts bigger than an inch is optimal. 

    A slope that is too steep can cause Tertill to flip, again possibly damaging the robot.  For that reason, Tertill turns away from any slope steeper than about 22° (40% grade).  This corresponds to two units of rise for every five units of run. (See Geometry does come in handy in the real world!)

    4. Weather and Watering - Tertill is weatherproof and can stay outside in all types of weather and is not harmed by sprinklers or soaker hoses. Tertill should never be submerged in water or sprayed with a power-washer as this might force water into the case causing damage. Note: You might have to clean the mud off the wheels manually if you have a prolonged wet period or particularly pernicious mud in your garden.

    5. Spacing- Tertill needs access to your whole garden to stop weeds from gaining a foothold. We recommend at least 12-inch spacing between plants and along the perimeter. This will also help ensure that each plant gets the sun, water, air circulation, and nutrients it needs for optimum health and yield.
