I planted a fennel seed from a dried herb packet i bought from an organic store. What variety if fennel do they typically sell as a herb?

It could be any variety of fennel and chances are it is imported. I suggest you keep growing it and if you like the end result save some seed for next seasons planting.

I live in Kingston Jamaica in the area where temperature at this time is 85 degrees. Can fennel seeds grow in this area under a shade cloth

Hello all, I have havested some fennel but have left the actual root in the ground and now I seem to have baby fennel growing again - from these roots. Does anyone know if I can leave the roots in the ground to keep sprouting? Much easier, if so, as I dont need to bother about tender seedlings. Cheers, Tracy

Hi Tracy, I've had fennel growing from roots left in a large pot a for the past couple of years - just because I hadn't bothered doing anything with them. They don't seem to grow as bulbous like this, and tend to bolt quickly, which is great for the insects. I have eaten a few baby bulbs from it too. :)

Hi Tiffany, Thanks for the reply - I might just leave a couple and see... Cheers, Tracy

I grew fennel last year in east london. It did very well but I didn't understand how and when to harvest it for some time. It almost overwhelmed me. I would rather have it as an annual in future.

What are the types of pest that attack fennel ????

I was given 4 seedlings and planted them about April they are growing well but I was unsure when they would be ready for use, looking at the picture they must still have a way to go as they are all feathery top ( I mistakenly thought the bulb would be underground like a carrot) and no sign of root. We have been have 6-11C degrees mornings here for the last 3 weeks or so and unually drizzely days (2-10mls)
