Fennel flowers attract numerous small beneficial insects.
Gather fennel fronds as you need them in the kitchen. Fennel can reseed to the point of weediness. Gathering and using the blooms as cut flowers will prevent excessive reseeding.
Prune back fennel plants in mid fall, before cold weather turns the plants to mush.
