Sure, a good way is to split the project into two parallel tracks. On the practical side, map out a clear schedule, budget, and roles—use a simple spreadsheet to keep everything on track. On the harmony side, set up a weekly “pulse check” where every volunteer shares a quick thought or concern; that keeps the vibe open and prevents grudges from building. Then, when a decision is needed, run it through a quick “cost versus benefit” matrix that everyone can see—transparent criteria give people confidence that practicality and fairness are both being respected. Keep the process short and to the point so no one gets stuck in analysis paralysis. That balance of data and dialogue usually keeps the garden thriving and the team happy.

Yes, a backup plan is essential. Set a hard cap on how much the budget can stretch, and for every new idea run a quick “budget impact” check before it moves forward. If a proposal exceeds the cap, have a fallback: either split the cost over a longer period, or replace it with a cheaper alternative. Keep a list of those “if‑budget‑exceeds” options on hand—so the group can pivot immediately and the discussion stays focused. That way you avoid heated clashes and keep the project moving smoothly.
