Climbing rose in a container

[Silkandvelvet]

I've treated myself to a David Austin climbing rose, and chose a short one that can be put in a container as I want it to grow on a sunny wall and there's nowhere to plant it into the ground.
Do you think this container would be suitable? (Pic attached)
I tried to get a deep one for the roots. It is 47cm deep, 32cm wide at the top and 20cm at the base.
The rose is a short climber, Strawberry Hill. It only grows to 3m
Thanks in advance for any advice.

I spoke to one of the gardeners at Fryer's roses about growing a shrub rose in a pot. He advised a big pot and pointed out some terracotta one as an example that were massive, and expensive, or a half barrel. He said to fill with John Innes no.3 but we could put polystyrene blocks in the bottom to help drainage, cut down on weight and reduce the amount of JI we'd have to buy.

I've bought a big terracotta pot for £34 from b&q who were selling ji no.3 for around £15 for two bags, iirc.

Tldr, not sure ask a rose grower, perhaps email David Austin?

And bump

I have exactly that rose and it's thriving in its pot. My pot is about 50cm at base, 60cm diameter and 50cm tall.

I feed it regularly and I added a sack of well rotted manure to the initial soil I planted it in.

It smells beautiful and is surprisingly disease free. Last year was a good year and it flowered three times!

I'd plant it in a big pot they grow a lot and need a good root system.

Thanks IcakethereforeIam, it was the expense and also the taking up of space that was putting me off buying a bigger pot, but I think that's what I'll have to do.
And thank you inloveandmarried, it's useful to have an idea of the size of container I'll need, good to hear yours is doing so well!

I've got a Gertrude Jekyll in a pot along with a standard olive tree and both are doing well.

The pot is massive, three times the size of the one you have pictured.

Twice a year I give them a feed of this stuff and mix it in well.

I have a lot of roses and I am vigilant about dead heading them.

Something more the size of a half barrel.. you might want to plant some salvias in with it to start with as I think roots can get a bit lost in a huge pot if you plant it on its own….in a few years it’ll have filled out the pot.

it would be happier in the ground if you could lever up a slab.

Ok, sounds like I'm definitely going to need a bigger pot then, and putting something else in to start with is a good idea, hadn't thought of that.

And thanks for the link to the feed @Jongleterre, I've never planted a climbing rose before, and I'm really hoping it does well!

What is the name of the rose @Silkandvelvet ?

3 metres is pretty high.

I tried a smaller climbing rose in a pot unsuccessfully I'm afraid. I think in my case the rose was too small for the enormous planter I put it in - you're better off starting with a smaller pot (which I know is difficult with statement plants like this) and then potting up as it gets bigger - or just be super careful with the watering.

@LadyEloise1 it's called Strawberry Hill.
I wondered if I could keep it pruned to 2 to 2.5m?

And yes @WobblyLondoner, I thought about starting smaller and possibly repotting later, not sure how easy that would be, and whether it might upset the plant.

Thank you @Silkandvelvet
