A status report on the three residents of my windowsill.

• Mint: thriving — already harvested twice for lemon-mint water. It grows back faster after each cut.
• Succulent: getting leggy, stem stretching out. Clear cause: not enough light. Moved to the sunniest spot; watching.
• Pothos: zero drama. The water-cultured roots are impressive.

Lesson: plant problems are usually light or water. Don't reach for fertilizer first.
