Taxonomic Information

Appearance

Fennel is a perennial herb that can grow up to six feet tall. It has feathery green leaves that are finely divided and thread-like, giving it a delicate appearance. The plant produces clusters of small yellow flowers that bloom in the summer and fall. The flowers are followed by small, oblong-shaped fruits that contain the seeds of the plant. Fennel has a distinct anise-like aroma and flavor.

Care Guide

Fennel is a relatively easy plant to care for and can be grown in a variety of soil types. Here are some tips for growing healthy fennel:

• Water: Fennel prefers well-draining soil that is kept consistently moist. Water the plant deeply once a week or more often during hot, dry weather.
• Fertilization: Fennel benefits from regular fertilization with a balanced fertilizer. Apply fertilizer in the spring and midsummer.
• Soil: Fennel grows best in well-draining soil that is rich in organic matter. Amend the soil with compost or well-rotted manure before planting.

Common Pests & Diseases

Fennel is relatively pest and disease-resistant. However, it can be affected by the following pests and diseases:

• Aphids: These small, soft-bodied insects can be found on the undersides of leaves and can cause stunted growth and yellowing of the plant. They can be controlled with insecticidal soap or neem oil.
• Cabbage Looper: These caterpillars can cause damage to the leaves of the plant. They can be controlled with Bacillus thuringiensis (BT).
• Powdery Mildew: This fungal disease can cause a white powdery coating on the leaves of the plant. It can be controlled with fungicides or by improving air circulation around the plant.
