Alba rose

hello

after receiving some very helpful advice about my hybrid tea roses, I wanted to check I’m giving this new rose the best chance. It’s an alba rose maxima and my hope is for it to grow up the side of the house and along the fence. It’s in a large pot as there’s no soil under the patio. I’ve given it a prune to remove touching stems and ones growing in the “wrong direction”. Is there anything else I ought to be doing? 

Thanks so much 
Bethany

    I don't think you need to do anything else this year.

    It's a large shrub, summer flowering, doesn't repeat so it flowers on old wood, not new growth. It should be pruned just after flowering so that it has time to make new growth to flower the next year. Yours is young so doesn't need much pruning. It should be quite bushy, but it can be grown as a shrub or as a short climber.

    I prefer to mulch roses with compost, rather than pebbles. It will need feeding in March with a rose fertiliser, then in May and July as roses in pots need more feeding than roses in the ground. You can water it with Tomorite tomato food every 2 weeks from March. In dry weather it will need a good watering at least twice a week. I expect you already know all that.

    I hope the pot is 60cms deep, or more. It is a big rose.

    Thank you! Yes it is big pot - ideally it would be in the ground but hey ho. Do you need to refresh the compost or just keeping mulching every year?

    The pebbles are there to prevent cats...I mulched with compost underneath them yesterday which was tedious! 

    Good to know about feeding, I didn't know that.

    I'm hoping to grow it as a climber.

    I remove the top few inches each spring and replace with new compost and work some rose fertiliser in. The trouble with plants in pots is that they are so reliant on us for food and water and the food gets washed out with the watering and heavy rain.
