I Bought A Lilac Bush, But Never Got Around To Planting It. It Has Been Outside In The Container It Came In. Can I Keep It As Is

Question

and plant it in the spring? If I can, what should I do with it to keep it alive until the spring? It has shed its leaves and has been outside in the container.

Answer 1

It should be fine to wait until spring to plant your bush. Try to find a spot outside where the plant won't be damaged by wind. You may want to sink the pot into the ground for the winter or provide it with some heavy mulch, but it needs the cold, and it should be alright outside.
