When is the best time to plant a tree?

When your heart sings to you, "Plant a 40 stone fruit tree todaaaaay."

Early spring and in autumn are best. Summer is not advised but is practiced in certain areas. Deciduous trees are best left alone unless trimming in the dormant winter months as a newly planted tree does not have the ability to properly establish it's root system into the new soil and only has about a 50% survival rate if re-planted.

The best time to plant a tree was 20 years ago, the second best time is right now
