young wild cherry

Better in the ground than in a pot. However, until you decide where it's going, just keep it watered. Not choosy plants, they grow in almost any soil, although neutral to alkali ground's best for them (clay or chalk). It will quickly outgrow the pot, so if you do wait until autumn, bear in mind its ultimate size (they aren't best pruned, although it can be done), as they'll reach 35 - 40ft. 20ft after 10 years easily.

Some councils or local conservation area like locally grown trees if your garden is too small for it, birds love the fruit

Thank you both very much for your reply. I'll keep watering for the moment.
