New oak trees

I have started some oak trees from acorns and now the leaves are drying and turning white. Any idea what is causing this? Pictures at attached.

    Mmm, not sure, but I collected acorns when from a famous oak tree (parliament oak) when my son was born fifteen years ago. All the acorns germinated and I potted them on. I still have them in pots on my patio. I did donate two to my local park when they were planting a new area, and I do want to plant out some more where they can be left to grow, I'm just not sure where.

    You'll need to pot them on as they grow, and also not let them get too warm or dried out. They'll need a soil based mix to grow on in, unless you're constantly refreshing the mix they're in. Those card containers will soak up moisture very quickly too which isn't ideal.

    If they're inside, they need to be outside.  :)

    All my acorn seedlings (Quercus robur)have oak leaf shaped leaves. Do you know what variety these are?

    Good point @fidgetbones. They look 'oak-y' from early on, which those don't  :/

    I wonder if they’re Quercus ilex … Holm oak?

    I am told they are white oak. 

    Do I need to put them outside even if temperature is below freezing?

    If they've been inside all of their life, then that's the reason for the leaves drying at the edges.  You'll need to 'harden them off' by placing outside during the day and bringing back inside at night, for about 10 days.  After that, they can (and should) be left outside permanently.  Depending on location, if your daytime temps are currently below freezing it would be a big shock, so would wait until daytime temps are a few degrees above before starting the hardening off process.  Most of the UK is in the latter category at the moment, so would be fine if based here.  I agree with the advice to re-pot them and would likely use ones twice the size, which should be good for a year.  I generally use tall 'rose' pots for tree saplings, so the roots have more room. :)

    That's the problem  :)

    Follow @BobTheGardener's advice re acclimatising them. If you're in the UK [even in colder, more exposed parts ] they should never have been indoors at all.
