| Kendra, which European country are you in? Every country will differ and have info in its own language so I doubt you can find dates for 'Europe' as a whole. In your position I'd try to find out the meterorological data for exactly where you live. I am in the UK and the concept of hard and fast first and last frost dates doesn't really exist. But you can find approximations - e.g. mine are 'mid-October' and 'early May'. They are so variable that they are not much use. Anyhow, you can work on your garden anytime, frost or no frost. All the preparation can to be done before the last frost. The link gives a zone map which might be useful. |

| Hope you get some help. France has a range of climates and it will depend where you are located. I agree that your best bet is to talk to local gardeners. But don't be surprised if they are a bit puzzled by the idea of first and last dates. The link might be interesting although it gives earliest frosts, not latest, and deals in extremes. |
