Fennel is one of the few plants that can be classified as a vegetable, herb, and spice all at the same time. The bulb is eaten as a vegetable, the fronds are used as an herb, and the seeds become a spice.
On a single tower, we can grow 36 fennels vertically. In most regions, the ideal time for planting fennel is from March to May or August to September. Fennel prefers cool growing conditions and will thrive in temperatures ranging from 15°C to 24°C (59°F to 75°F). Avoid planting fennel during the hottest part of the summer, as heat stress can cause the plant to bolt.
