Hi how do you encourage it to bulb?

Probably like any crop, plant it during the recommended time period, Feb-April for you. Growing time 14-20 weeks. Good soil regular watering. It probably needs the warmer temps to germinate and grow and then cooler temps to mature and form a bulb.

When you get them going, leave one to go to seed at the end of the season. Leave it in the ground afterwards and you'll get another cropping of bulbs appearing at the base of the old plant. I have seeds if you're still stuck.

I started a shoot from a store-bought fennel. It's about 3" high. When can I plant this? From your chart it seems like only March? Thanks!

Have lots of this growing wild on my place. The only recipe we tried with the bulb was a stir fry but we got put off because the flavor was too strong. Are there recipes to take the strong taste off it!? Thanks.

I recommended sauteeing or roasting it slowly in butter or olive oil with a dash of balsamic vinegar - this caramelises it and makes it taste sweeter. You can add a dash of brown sugar too.
