Growing notes
- Parsley sends down a taproot — use a deep container (≥8" depth) for best results.
- Likes a steadily moist, rich mix; don't let it dry out completely or leaves go bitter.
- Tolerates part shade better than basil — useful for east-facing balconies.
- Liquid-feed at half strength every 3-4 weeks for ongoing harvests.
- Treat as an annual in containers — flavor declines sharply once it bolts in year two.
