💧 WateringLow to moderate; drought-tolerant once rooted
🧺 HarvestFresh leaves (fronds) can be picked throughout growth; for seed, harvest once the flower umbels turn brown and the seeds yellow, usually ~3-4 months after sowing. Cut once the seed heads dry and shake out the seeds.
🪴 SoilLight, well-draining soil; intolerant of heavy clay
⭐ DifficultyEasy
🗓️ SeasonSpring/Summer
📅 Calendar is for the Northern Hemisphere; in the Southern Hemisphere shift sowing times by ~6 months.
💡 Key tip: Fennel is a good companion to almost no vegetable; its allelopathic root secretions hinder the growth of neighbouring plants or cause them to bolt early. Keep it away from tomato, bean, pea, cilantro and caraway. It is best grown in a separate bed or container.
🤝 Companion logic: Fennel strongly draws beneficial insects (solitary bees, ladybirds, hoverflies, parasitic wasps); for this reason its best use is to grow it apart from the vegetable bed, at the garden's edge. Because of its allelopathic root secretions it should be kept away from most vegetables, above all tomato and other nightshades, all bean/pea types, cilantro and caraway.
