To submit plants in Build a Ring Farm on Roblox, go to the Plant Contracts board near the seed area, check the current request, and turn in a plant that matches the required type, value, or rarity. After completing the requirement, interact with the finished contract on the board again to claim the reward.

How it works

  • Open the Plant Contracts board near the seed collector / seed reroll area.
  • Read the mission, because it may ask for:
  • a specific plant type,
  • a plant above a certain value,
  • or a plant of a certain rarity.
  • Bring the correct plant to the board and submit it there.
  • When the mission is complete, interact with it again to claim the reward.

Helpful tip

If you are unsure which plants count, check the plant’s category or traits before submitting, since some contracts are type-based rather than just rarity-based.

Rewards

Completed plant contracts can give cash, boosts, fertilizers, mutation sprays, treats, and contract XP depending on the mission.

TL;DR: find the Plant Contracts board, match the request, submit the right plant, then return to the board and claim your reward.
