Some roses require more work than others. Ask yourself if these particular bushes are worth the effort.

Lucas,

Roses are much beloved all over the world. They can be very successfully grown in a variety of climates, but the variety grown is critical to success. Not all varieties do well everywhere. Just because a rose is sold locally does not necessarily mean it will thrive for you. Merchants often could care less if you succeed, and frequently, knowingly sell roses that are difficult to care for after you buy them, just to make a sale.

Miniature roses are often sold as 'throw away,' plants in the USA. They come into the nursery in tip top health, full of blooms. You buy a mini thinking it will only enlarge and prosper under reasonable care. You quickly find out that they are very disease prone, and need spraying to grow well. Spraying that they received religiously from the grower that provided them to your retailer, to get them healthy and full of blooms so that you will buy them. I would say that most folks that buy a mini in pristine condition, watch it decline day by day under their reasonable care until it is almost dead, and consequently gets discarded...a 'throw away' plant, indeed!

I suspect miniature roses are sold as, 'throw away,' roses in Rio, too.

My advice to you is to search for a local, exerienced amateur home gardener rose grower in Rio, who grows roses successfully there, and if as you find out the details of that person's management program, and determine that it is ACCEPTABLE TO YOUR LIFESTYLE, duplicate it with the roses that person recommends and has success with, and you will have success, too.

Roses are usually very labor intensive in most climates, with minimal care needed for them in only a few climates...mostly those that are low humidity with mild winters. Your climate is wonderful in many ways, probably for a number of classes of roses, but your humidity encourages continual black spot issues for black spot prone roses such as minis.

Try to find out if there is a rose club in Rio. I imagine there is. Members of rose clubs are usually overjoyed to give you sound, practical help. Ask at nurseries who in Rio grows roses successfully in their gardens, and who to contact for advice.

Also, public gardens where roses are grown are a great source of help, too. Gardeners in charge of the gardens are also usually very helpful.

I wish you success!

Moses

P.S. I wish I could grow gardenias, plumerias and jasmines like you can in Rio! Alas, they need warmth all year long....an impossibility here, except if they are pot cultured which presents almost insurmountable obstacles to success here where winters are severe.

If you love them then yes, they are worth the effort

I bought a mini at the grocery store. It turned into a blackspotted mess. To me it wasn't worth the hassle

But, I have several that I ordered from For Love of Roses .Maybe because I paid more for them I will spend the time and money to keep them clean

However, when I read about a potential mini I choose the most disease resistant one I can find

So, do you love them? Do they make you Happy? If not then give them the heave ho

Thanks a lot for all your answers! Especially to Moses, you really helped!

Blackspot is always in the environment, even if you don't have roses. So if a rose is susceptible to blackspot it will get it in the right conditions. If a rose gets it all the time, then you have to decide if it's worth it or not.
