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!

Where can I get seeds or seedlings I am in Hastings Vic ?

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?

Hi Heather, I think I've heard that Bulb Fennel can have male or female plants for example some will fillout to a bulb and others will stay sort of flat. If thats not the case then its possible you actually have a Dill plant! I'd persever and see what you get and dry some of the fronds for kitchen use.

When your crop has finished what do you need to do to the soil to make it ready for your next crop? I understand about crop rotation but not sure when I should be adding fertiliser and compost.

Late reply..but here goes.. all I do is a mix of compost or worm castings..maybe with a dash of seaweed solution or worm juice. Even a crop of peas just to help break up the soil a bit with a nitrogen fix.

My fennel seems to be making more frondy vegetation and the bulbs don't seem to be growing.What am I doing wrong? My soil is good and I feed my plants with worm tea.
