Cherry blossoms tree

[user789653241]

Hi, I am not very good at gardening.

I have planted cherry blossom tree in our garden, in memory of my dear friend when she past away about 12 years ago. It was meant to be a miniature tree.
Now, actual trunk bit is not tall, but tree itself is very tall, blocking a sun light on one of our window.

My dh trimmed it few times over the years, but we are both totally novice and don't know what we are doing, and every time he cut off, it seems to grow even taller.

I really love this tree, and last year, he cut it really badly and we had very very bad flowering this spring. I don't know what to do, but it really become too tall, but don't want to damage it again.

Can anyone give me a tip please? What do we need to do to keep the flower blossoming but also keep it not to grow so tall?

Well if you cut it now, you will cut all the shoots off which are carrying next year's buds so you will get no flowers. Best time would be to prune it next year as soon as it has finished flowering.

Trees are trees, they don't grow to the height you want and then stop, sorry

A lot of Cherry Blossom trees require pruning in late August. Spring pruning can cause the sap to run. If it was me I would do a dramatic prune.now then Trim it each August,

Do you k ow which variety it is.

Thank you, both.
I think we need to do dramatic prune now, since it's really become too tall. And make sure to do it after flower each summer.
Have no clue about the variety.

Pruning at this time of year is not good; energy reserves are low and fungal spores are abundant in the air. Either wait until dormant (mid November-Feb, avoiding freezing temps) or ideally August (avoiding drought).

Oh, thank you both.

With your advice, I think I will wait till mid Nov, Hoop, and have to do a bit of drastic cutting.

The tree was meant to be a miniature, in a pot. I planted in our garden, and it was fine for years, still remained rather small. But now the really thick trunk part is not long, but it just seems to be growing upwards.
