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

Post a question, comment or tip about Florence Fennel

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.
