Rose problems

[Taliskerskye]

So I have a few Bush roses. All happy flowering away. I have one that is 3 years old. It’s never flowered. Year 2 and 3 it’s grown massive side shoots from low down. That I don’t even notice until they’re taller than the actual shrub!
I figured last year it was an anomaly and lopped it off.
But 2 years in a row! Any thoughts. Roses next to it. Just fine

Those side shoots are suckers that grow below the graft. Roses are often grafted onto a root stock to help them be more hardy amongst other reasons.The suckers will take the energy from that rose and prevent the flowering. You should remove them as close to the main stem as possible.
Presumably the other rose bushes are grown on their own root stock and have no suckers.

Are the side shoots really strong and dead straight? If so, they are suckers. Cut them off as low as you can.

Meanwhile you can also prune the rest of the plant back, though Autumn / Winter are the best times for this. Cut each stem diagonally, just above a new shoot/node that points outwards.

Do you feed the roses? Blood, fish and bone is a good mixture which you can buy. Do they suit the soil type you have?

Great thanks @SoapboxFox and @Beebumble2
Yes they are indeed poker straight! Ok I’ll take them down hard to the ground. Weird it happen 2 years in a row.
I’m not sure if the others are grafted or not. They were all bought from David Austin!

I will give them a good feed too.

By co incidence, Joe Swift writing in the Times gardening section today, says to tug them off. Apparently cutting them leaves enough stem for them to grow again!
Thanks Joe.

Oh interesting maybe that’s why they grew back from last year!
