Perhaps a scheduled campaign of watering in a stew of good soil microbes, sourced from different suppliers, will kick your roses into vigorous growth. A pH adjustment, if needed, may help.

Foremost, don't beat yourself up for your presumed haste. Your roses' slow progress may be due to other factors, factors unrelated to 'Rose Replant Disease.' Growing roses is a constant learning experience through which we amass considerable information, so consider this specific case a knowledge enriching addition to your wisdom chest.

Thank you everyone.

I'm only really concerned as they're in very prominent positions and a few small canes sticking out of the ground will inevitebly draw criticism from the people in this house who don't want this many roses 😂

I will try a natural root stimulant and see if it makes any difference

Do you have any photos?

It's not the best picture sorry. This is Scarborough Fair and it hasn't done much of anything. Its still the same height it was when it was planted last winter.

I can't say why that would be, but the foliage looks healthy. I've had roses stall in their growth after moving them, and after a poor growing season or a hard winter and after a year or two they do fine. I am careful of what I buy. I only buy online from a reputable rose grower and I only buy bare root stock to minimize any potential issues. I also try to choose roses that are known for health, hardiness and vigor.

I had a rose that became diseased at the end of it's first season and the next season it started out fine and grew okay, then the next season it started out awful and I cut it back to the ground and it grew in healthy again. I am patiently waiting to see what it will do next year, but I like to experiment in allowing a plant to manage for itself and recover.

So, it just depends on how you feel about giving up space to a plant that you need to be patient with. Depends on how confident you are about the health and appropriateness of the plant you bought. Unless you really need the space or are not that crazy about the rose, I'd give it another season. I'd add some organic compost and some organic alfalfa meal around the base of the rose, not too close to the canes and keep it evenly moist the rest of the season and see what it does in the spring. You could also dilute some organic seaweed emulsion and spray the leaves with it every couple of weeks for the rest of the season. Give it another dose of organic compost and alfalfa meal next spring and if it doesn't improve, then it would seem something is not right.

Doesn't look bad to me. I would put down some mulch. Sometimes nothing much happens above ground while a lot is happening below ground. Once the roots get established, top growth commences.

Grafted roses start faster. Even grafted roses don't reach their peak plateau until Year 3.

I agree with the recommendation for mulch, and my personal preference is shredded cypress, as it does not blow away, and helps discourage some insect pests - the insect benefit is mild at best. It also helps prevent fungal disease, keeps soil from overheating, and helps prevent soil evaporation.
