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)

don't know if you will get this but I thought I would make a comment by now your fennel should have had a large swolen stem you If you didn't eat it it would become skinny again and then grow up to seed if it didn't you will have ordinarily fennel or wild fennel if it made a swolen stem you will have a plant called Florence fennel

Seeds are available from several Australian heritage and organic seed suppliers. Diggers Club is closest to you. You can buy online...or take a quick trip across the Peninsula to Dromana - why not enjoy a day out at their gardens and cafe? I'm sure they'd be happy to answer any questions you have too!

Bunnings has the seeds and punnets of seedlings. Might be a bit late to get seeds going.

Hello, I live in Edmonton. At our community garden, we are trying to grow Florence Fennel. The plant is healthy, with fronds a metre high, but it is not forming a bulb. The root is ten centimetres long. If we cover it to get over the early threat of frost, which is often a risk in early September, we may get warm and sunny days trough to October. Is there anything we can do encourage the plant to form a bulb? Thank you for taking our question. Morris

Did you have any luck finding the fennel seedlings? I live in SW NSW and have a couple of patches of fennel going wild and self seeding. I'm on a property and am experimenting with what I can grow that is easy care - and fennel is one of them (so long as the soil is kept mulched during seed germination time and early seedling stage). I don't water my gardens often so I don't get as good a bulb size than if I did water - but fennel doesn't mind the lack of watering once established.

We have just purchased a home with an old herb garden, I am sure that fennel is growing but it doesnt have the bulb - it has been left overgrown for years. What should I do pull it all out or persevere?
