Ingrid, I don't know if any of the big seed companies like Yates sell them. I order my fennel seeds from the Italian Gardener. I have also bought seeds from Digger Club in the past (but the quality of the bulbs wasn't as good as the italian ones). Most of the mail-order companies carry them - Cornucopia, Eden Seeds and New Gippsland Seeds are a few. A quick google will take you to their websites. Hope this helps

Does anyone have any tips/advice on germinating Florence Fennel? It grows really well in our region but germination seems a bit hit & miss whether I use a heat pad or not. Cheers...Jan

Fennel might need a period of cold to break its dormancy. try putting it in the refigerator for a while before germinationg it.

The fennel I planted has several bulbs growing together (that's how it came. Should I separate them, if so, how?

@ Janet You may have planted the wrong kind of fennel There are two kinds. Florence Fennel produces the bulb at the bottom and Bronze Fennel just goes to seed and is usually grown for the seeds or the feathery leaves. Bronze fennel is the one that grows along the sides of the roads (feral) in many parts of Australia.

That explains why my fennel just grew up and went to seed without growing a bulb. I planted it in late spring but it obviously should have been late summer/autumn.

I am in pinjarra W.A and would like to know the right time to plant my seed?And can you let it grow above the ground like an onion or a beetroot?Because in recent times i've been told that as they grow you need to pack them up.

Do you have to get certain seed which can be planted now? I have some seed but the packet says to only sow it in spring/summer... it doesn't say you can sow it in autumn as well? Thanks Nic ;o)

As fennel is a perennial I would expect new growth to come from the old plant. Also, for cooking - slice lengthwise in half, or more if they are big, place in a baking tray, sprinkle with salt & pepper, drop in some butter and bake covered at about 180c for about 20 mins.

i have a question: the old fennel plant is still in the ground. will it grow a new bulb from that or should i sow seed to get new plants?

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?
