The basil plant was smaller than I expected when I brought it home. Two thin stems, a few bright green leaves, soil still loose from the nursery pot. I set it on the balcony rail and stared at it for a moment, unsure why I felt responsible already. Plants have a way of doing that. They do not speak, but they depend.
I read the label carefully. Full sun. Regular watering. Good drainage. Basil grows best with at least six hours of sunlight and soil that does not stay waterlogged, because excess moisture can promote root rot and fungal disease (Simon et al.). That part mattered. I moved the pot slightly to catch more afternoon light.
