2019 was my first year growing fennel. I grew both from starts (Orion I believe with the rounded bulb ), as well as from seed (Selma Fino from WestCoastSeeds). Initially I planted them out of curiosity as I do enjoy fennel in salads, and like the look of both fennel and dill plants. After year one, I recommend a fennel planting to anyone considering it, and will be planting several pockets of fennel again this year.
First, my fennel did very well, both those started from small pants and those started from seed. After a bit of a slow start, the seed fennel took off and by year’s end were massive.
Next, they were a very effective draw for pollinators and various types of wasps. Based on what I’ve read, I believe several of these were predatory wasps, which I was very happy to have around. The fennel flowers bloomed on immense heads and at any given point were covered by bees, wasps as well as ladybugs which really seemed to favor the plant.
Recommendations?
- If you’re planning to eat them, plant extras (so you can have the benefits of the ladybugs and wasps throughout the season) and don’t wait too long to harvest. If I could do it over, I would have pulled the bulbs earlier as the ones we ate were a bit woody. According to WestCoastSeeds you should harvest the fennel bulbs before the flowers form… in which case I wasn’t even close.
- Think about how you might stake them. I planted my fennel fairly close to some of my pepper plants (to the north and east so as not to shade them) and later in the summer the fennel started to bend over top the peppers. I tied the longer stalks back, but it wasn’t very nice to look at. This year I’ll better plan how to keep the fennel stalks and flowers from shading the peppers, while still having them close enough for the wasps and ladybugs to wander by.
- Don’t forget the seeds! At the end of the summer I saved a fair number of fennel seeds from one of the plants. After they’d try they served as a very nice snack over the next several months. That said, don’t leave the little ‘connector’ to the seed itself. Those things don’t fall off easily on their own, and dry into little gum-piercing spears. You’ve been warned.
- Don’t plant too close to dill. I read this somewhere, but given that they’re closely related you want to keep them away from one another.
That’s it. I didn’t experience any real downsides to growing fennel in my garden, and observed several valuable benefits that will see fennel become a constant presence in my garden going forward.
One more thing. I didn’t fully clean out my fennel at the end of last year. On inspection this week I noticed that shoots were erupting from the older bulb / roots. I pulled the old plant and cut the base into several pieces, each with a new green shoot and placed them back in the garden bed. It’s been several days, and so far they’re showing no ill effects, so I may have found an easy way to get a head start on this year’s fennel patch.
