Shaped privet (sp?) type plant???

[Wiggy29]

I bought a lovely shaped privet reduced in B&Q the other day but when I got home there was no care label. I've potted it in a deep pot with a drainage hole at the bottom, I put gravel in bottom, lighty loosened the root ball and planted the bottom of it level with the top of the plant.

A few questions- how often should I water it (it's outside of front door so partially sheltered by wall/ canopy) and, do I need to put it in a bigger planter? The one I out it in is only about 5cm wider than the root ball in each direction but when I looked on the internet it said this type of plant needs to be in a planter at least twice as wide as the root ball.

Thanks in advance- you can probably tell I'm a bit of a novice!

You shouldn't need to water it if it's outside in all this rain.
If we get a dry spell you can stick your ginger in the soil & if it feels dry give it some water.
If you want to repot it, I would wait till the weather gets a bit warmer, around late March, as that's when most plants begin to think about starting into new growth.

Finger not ginger

Aquelven- was baffled for a moment- thought the ginger was some sort of special gardener's tip! Thank you for the advice
