Rose problem

Only planted them out of their pots about a week ago, fine when I got them. The petals are dropping off and leaves don't look good. Spotted some green fly, sprayed them with green fly and other insect spray, Fed them today with Westland Rose High Performance flower plant food. Watered them too. Any advice please?

 

How deep are the troughs that you've planted them in? Roses grow quite deep roots and if the pot is to be permanent it should be around 60cm deep. What sort of compost is it? Roses need something a bit more earthy than ordinary potting compost, like John Innes 3 which has loam in it. Or compost with some garden soil, some rotted manure too perhaps. Have you kept the soil moist? They prefer a good soak every few days rather than a light sprinkle every day.

They could just be suffering from temporary shock and will pick up. Where they in pots from a garden centre before? Did you keep as much of the old root ball with its compost on as you coul?

 

And spraying already stressed plants is really counterproductive. But those planters look utterly unsuitable to even the smallest rose.

 

Troughs approx 8" deep, they could be moved to the planter below which is around 12" deep.
Compost Westland Multi-Purpose.
Soil is moist, The roses are in the same ball when they were removed from their pots;

 

As others have already pointed out, unfortunately the trough is too shallow and actually even the 12" deep planter is probably not enough. Also, multipurpose compost is not very suitable for roses I'm afraid.

What roses are they? And are they shrubs or climbing roses? I know that for David Austin roses for instance, the website recommends a minimum of 45cm for shrub roses and 60cm for climbing roses.

 

Question: First, I am not in anyway a rose expert. My garden does not have enough sunlight for me to plant many. However, I do have a Zepharine doing well next to the deck. Here is the question, I believe it seeded a baby in the soil next to it, the leaves look right, its now about 6 inches tall, I am just leaving it alone for now. Is it worth it to actually dig it up, and pot it, setting it to the side in a "safer" place, or just leave it alone, will it actually be a decent climber one day? I guess it could be an interesting experiment. Anyway. that's it.

 

I've never heard of that happening with a rose before. Are you sure it's not just a shoot from the rose, growing from under the soil level? If so, it might be worth removing some of the soil to make sure it is coming from above the graft (if it's coming from below the graft, it is a sucker which should be removed).

 

Ok, guess it could be that, its about 8 inches from the mother base. Would it go that far?

 

Yes, I think it could. I think @CostasK could be right. Dig down and have a look. I had a Charles de Mills rose that did that and spread quite a bit sending out new babies. They were all like the parent not like suckers.
