Spruce (fir) tree seeds from Israel

Some years ago, I bought back two cones from Israel (sentimental reasons) and recently put a couple of the seeds into some compost. Surprisingly they have taken root and I now have four little bright yellow green spikey shoots almost like the spikes of an upturned umbrella. Do you think they will survive here and can you give me any tips on how to help them survive in our climate.
