Four weeks in — same site, same watering cycle
Our BC Interior pilot site: 30°C stretches, wind, full sun, no shade. Every tree on the same 7-day cycle. The photos argue for themselves.
Observational photos at four weeks post-planting. Measured survival and soil-moisture data come from the instrumented pilots.

Young trees need water every 2–3 days; crews come every week or two, and summers are getting hotter and longer. Tree Guardian closes the gap at planting: a drop-in establishment kit whose bag and wicking irrigation deliver water to the root ball continuously, 7–10 days per fill, while inoculated biochar and mycorrhizal fungi improve the soil it roots into.
Watering guidance: daily for two weeks, every 2–3 days through week 12 (University of Minnesota Extension; municipal policy in Saint Paul). The same guidance notes a standard surface bag empties in 5–9 hours.

The pilot: matched controls, sized to your program
Same species, same neighbourhoods, same planting window — survival measured at 12 and 24 months. One avoided failure covers thirteen pilot kits; the conservative model projects a 10-point survival gain.
