Plant science, smart-home gardening, and the engineering behind precision plant care.
Smart-home gardening

Snake plants are sold as unkillable, and that reputation is exactly what kills them. Here's how to read the plant in front of you — its light, its pot, its slow week — instead of watering a desert plant on a houseplant schedule.
