I bought a crabapple tree about two weeks ago and it has still to show any new growth. How long does it take to show any and how do I know it is actually healthy?

Do you mind sending in a photo of your crabapple? It would be helpful for me to see what you mean by not showing any new growth. Does it still look dormant and doesn’t have any leaves at all? Or, are there leaves but not any new leaves? Something to look for is healthy stems on the tree. If they are dried brown and snap off easily, there is definitely a problem with your tree. However, if they are green and pliable plus the tree has healthy leaves, then it is probably just getting settled into its new home. Take a look at our First Editions planting and care guide for tips on growing healthy plants. And, if you have a moment, please send me a photo of the tree.
