welcome to GoY Amyjane.

the tree had its buds before you planted it. then it has taken time for the plant to settle in and get its roots down properly. I would expect your tree to flower next year. keep it well watered especially if we get any dry spells this summer.

Trees often flower in the nursery pots, because their roots are restricted. When planted out, they often forgo blooming for the next year or two, while they concentrate on growing deep roots and strong trunks. As Sbg says, it will probably bloom next year, but don't panic if it doesn't, since it will almost certainly bloom within the following two.

Thanks guys very helpful and that makes perfect sense will await patiently ??
