All you can do is wait Justine. Assuming you planted bare-root trees, sometimes they sulk and decide to just grow roots for a while before leafing-up, but sometimes they do not take and die. If you use your thumbnail to scrape off a thin layer of bark near the top of the tree and see green, the tree is still alive. If it is brown underneath the bark, try again lower down and if that is also brown it's dead and you should ask for your money back.
