From what year do shrub and climbing roses planted with bare roots begin to produce large numbers of roses?
My climate is dry subtropical and in my case since I planted them two years ago they have produced few or no roses.

It depends on climate, soil and understock used. Some start immediately, most need 2-3 years, others more than 5. In your climate you might also do better with Tea, Noisette and China roses rather than Hybrid Teas or Old garden Roses, which need a period of cold in winter.

Dear Jedmar
Here in winter it usually reaches around 11 or 12 degrees Celsius on some days. Would that be enough for a cold winter period? Here the climate becomes more humid and colder between mid-November until the end of March, although it usually varies according to the year.
I guess I'll have to wait another year then. I hope to be lucky with Variegata di Bologna as it belongs to the Old Roses, although some nursery websites recommend Bourbon roses for hot climates.
Kind Regards
Alejandro

I believe some roses need temperatures lower than that. I have heard that in Florida temperature drops to minimum 5 degrees in winter and that is not enough for old garden roses to florish. Maybe you could check what other members are growing in Florida. Look at Gardens/List by Location/USA/Regions/Florida.

You might try 'Old Blush' if you can get one. I have a house in Belize which is slightly more southern that the Canary Islands, but also in the temperate zone. 'Old Blush' is quite common here, a former English colony usually labeled "English Rose". It does bloom on and off all year and grows in sand reasonably well.

Might the black stems and mildew be downy mildew. Maybe take a look at the photo's of my comment on Home Run from Carruth.

Thanks for the advice.
I have not been able to find the photos you are telling me but I have searched the internet. It looks like what my rose bush has. However, in the areas where the black spots are, there are some small mealybugs although they are almost like small scales and are not seen in the image. Recently it was infested with ants.
But I think that by repelling the ants with poison, pruning and using some alcohol on the trunk the problem was solved. The inside of the stem is healthy so I think I can be calm.

I know those aphids with that downy stuff from apple-trees, they are called over here appelbloedluis or wollige bloedluis: (literally translated) Blood-aphids. ((Eriosoma lanigerum)) They shed wax-threads.
In apple trees, those aphids can cause/transfer canker.
Do You have photo's of Your critters?

Hi Jay-Jay!
What you tell me does not seem to be the problem but thank you for your comments. The creatures are the small brown spots on the trunk. I think they are called rosebush scales. I looked on the internet and apparently they can be treated with alcohol. But I really don't know if they are related to the black spots. Once I treated them with alcohol, the black regions stopped progressing but I will have to wait a little longer to confirm.
The rose bush now has about seven new shoots. I will upload some photos here when these have formed leaves and I can see the color of the new secondary stems formed.
