### Care instructions

1. **Harvest at the right size.**  
   Fennel bulbs are ready when they reach about 3–4 inches (7–10 cm) in diameter. Smaller bulbs are more tender, while larger ones can become tough.
2. **Don’t wait too long.**  
   Overmature fennel may become fibrous or start to bolt in warm weather. Check plants regularly as bulbs develop.
3. **Cut at soil level.**  
   Use a sharp knife to cut the bulb at or just below the soil surface.
4. **Remove outer layers if needed.**  
   After harvesting, peel away any tough outer layers.
5. **Harvest during cooler weather.**  
   Fennel prefers cool conditions. Harvest promptly if temperatures rise to prevent bolting.
6. **Use the fronds and stems.**  
   Feathery leaves and stems are edible and can be used fresh or dried.
7. **Store properly after harvesting.**  
   Store fennel bulbs in the refrigerator and use within several days for best texture and flavor.
