LOOKING AHEAD
Rain Expected Tomorrow — Hold Off Watering

NWS shows 70% chance of showers tomorrow with 0.6″ expected. Consider skipping today’s watering — your salsa garden plants will be fine until the rain arrives.

SoilStack looks ahead at tomorrow’s forecast. When rain is likely, we suggest holding off so you’re not over-watering right before a storm.

Weather changes. Your plan should too.

SoilStack watches for rain, heat, dry stretches, and cold snaps, then helps adjust the tasks most likely to change. Watering tasks move forward when rain is coming. Transplant dates shift back when nights stay cold. Your calendar stays useful instead of rigid.

Know what actually needs your attention.

Every task is ranked by how much it matters. Miss a planting window? That’s flagged as urgent. Skip a watering by a day? No big deal. Choose your pace — Easy Going, Balanced, or All In — and your calendar focuses on what counts.
