A small roof can yield astonishing liters. Fit gutter guards, add a first-flush diverter, and anchor barrels safely to walls. Paint tanks to shade algae, label shutoffs boldly, and route overflow to swales or fruit trees that welcome every cloudburst.
Group plants by thirst and stage: seedlings under gentle drip, established perennials on deeper intervals. Use pressure regulators, filters, and color-coded valves to avoid confusion. A laminated map by the tap turns panic into confidence when a neighbor helps during holidays.
Consider laundry-to-landscape loops where permitted, sending soap-sensitive flows to ornamentals, not lettuces. Mulch basins soak pulses, while soil biology finishes the job. In dry spells, shaded tanks and scheduled top-ups protect seedlings and prevent heartbreak after weeks of hopeful growth.
