Climbing roses in planter help

[Bohogardner]

I’ve had 3 planters made that I’m
going to attach trellises to and plant climbing roses into them. Although the largest is 210cm long, it’s only 36cm deep and 30cm width and I’m now worrying that it won’t be big enough. I did speak to David Austin who advertised 2 plants max for this one and 1 plant max for the others which are 120cm x 36cm. But now I’ve purchased the roses, panic is setting in. I’ve seen lots of people on instagram have beautiful climbers in pots so didn’t initially think of this when I first ordered my planters but upon doing more research I’m second guessing myself. Has anybody had any experiences with climbing roses in pots and how well they’ve done? Thank you.

I have a climbing rose in a pot and it's not doing well. This is the 2nd year in a row I haven't had a flower bud, despite feeding & watering well.

I have a climber in a pot at the bottom of an arch, and it's happily covering its side of the arch (at about 2 meters high). It's called Starlight Express. I don't think it will get any bigger. I think keeping them well watered and fed is the key when they're in containers

Oh what a shame 😔 What size pot is it in?

I’ve got Gertrude Jekyll in a big pot and she’s doing ok

ahh that’s amazing! Yes, I’ve read that they’re a lot more high maintenance in pots, which I don’t mind. Fingers crossed for mine!

I have a climber in a standard plastic pot, I've just measured it's 35cm high, 45cm diameter, narrower at the bottom..it's climbing up a pergola. It has been there about 4 years, plenty of flowers every year, early. I don't know the variety,it has small close petals light pink, heavenly perfume. The label has blown off..

Oh that is amazing to hear! Thank you so much for your reply. It sounds divine

Will the trellis be attached to a fence/wall with the planter stood at the foot of it, or are you attaching the trellis directly to the planter itself?

Just realised I’ve accidentally not been replying to people properly! I’m new here, sorry.

I’ll be attaching the trellis to the planter itself. The planter is on wheels as I need to move it around to gain access to pipes/hose/outdoor plug which I’m using the trellis to hide

Ah - watch out for it getting top-heavy then, as it could blow over.

Hello OP, Choosing the right size for planters is not easy, I agree. It seems you are having yours made for you? In that case they should easily be modifiable. I would ask them to make them deeper. At least 60cm or double the depth you had planned. This will give your roses plenty of room for their roots.

I just read about your planters connected to the trellis being on wheels . That sounds a bit complicated to move for maintenance! Why not just use a beautiful trellis in a diamond pattern and have a few pots with tall plants in front?

I wouldn't recommend roses either in that container since it will be bare in winter. Something like a persistent jasmine would be better.

If it is to late to change them, you could always put your low containers elsewhere for a few annuals and herbs. At any rate you can try what you have planned . It may work for a few years. Learning by making mistakes is part of gardening! Best of luck.

Roses aren't deep rooted..you will have to keep them very well watered in a container, and fed,we tend to use liquid tomato feed you dilute.
