Help save my dying rose buds

4 years ago

I’ve just purchased a pot of miniature roses, it was really beautiful. I watered it once on alternative days early in the morning because I find that the soil is still wet if I had watered it the day before..
But after a few days, I noticed the roses buds were turning brown like the picture below. It hasn’t even bloom. Since it turned brown, I plucked it and it easily came off. I’m new with roses, really like them a lot.

I don’t know what’s wrong with it. Is it infected with fungus? What can I do? Please help. Appreciate any advise. Thank you.

    Don't worry.

    In my opinion this is kind of par for the course with minis.

    They are often grown in greenhouses with rather artificial conditions and they get a bit of a shock when removed from that environment. Both of the minis I bought did the same thing at first, buds looked just like yours, and both thrived in the end.

    Did you repot it? They often come in tiny pots. If possible, pot your rose up in a bigger pot than the one it came in, maybe a 2- 3 gallon for a mini is a good start, with some good soil and good drainage. A little slow release fertilizer in there too.

    Then just give it some time and it will grow, making new buds and flowers.

    Regarding watering, every other day is a bit much. Basic method: Dip your finger in the soil and see if it still feels moist two inches down. If yes, don't water. If it feels dry then water. If you repot it to a bigger pot then use a stick to check moisture deeper in the soil.

    Thank you very much for your tips. I will take note of the soil moisture level before watering again!

    I have actually repotted them into a sightly bigger pot than it’s original. Here’s a picture of them, i don’t even know the species.

    And I hope I’m not asking a lot but can you share some basis knowledge like..What disease/fungus miniature roses are prone to and what should I do to prevent them?

    Thank you 🌹

    Anything that can affect a full-sized rose can affect a miniature.

    So blackspot, rust, mildew, botrytis, canker etc.

    Climate zone, humidity levels, etc will affect the likelihood of various fungal diseases. Fungal attacks seem to happen more right after a flush of flowers, and in the fall. Often they can be alleviated by simply pulling off affected leaves and pruning diseased canes. Don't let fallen leaves stay on the soil surface.

    For prevention, you could spray with a fungicide a few times a year, and for that you have many options, from organic (Serenade and the like, or bicarbonate, or sulphur or copper-based sprays) to synthetic ones like FungusClear, Provanto, etc. That's up to you. Never spray when it's hot outside or you may burn the leaves: I learned the hard way not to spray in summer.

    But even without fungicide, you can do a lot to prevent disease by just keeping your rose in a sunny, well ventilated place, and making sure it gets adequate nutrition.

    Your rose looks beautiful and very healthy! Nice dark glossy leaves are a good sign. Don't worry too much, and enjoy your rose!

    Julie, it wasn't clear to me if you were attempting to grow this rose inside. That will cause buds to abort just like what you are showing us. Is the beautiful hanging pot the mini in question--the leaves are gorgeous. Where do you garden? Is it a dry area? Here is a six foot tall mini from the grocery store that I have grown in ground for about 12 years. We get no fungal diseases, so I never spray. Diane

    Wow Diane! That is fabulous! I don’t think I have ever seen you post this rose.

    Thanks, Stephanie, but I have posted a few photos of it and I don't want everyone to get tired of them. I'm so amazed at what this looks like. In spring, the blooms are about full sized, and look a bit like an Austin. Then when the hot weather starts, the rose produces smaller blooms, which get bigger when it cools down in fall. Sort of like my PAoK. Diane

    @seasiderooftop thank you very much for your kind advise. I’ll keep that in mind. I’m very new to roses. I live in South East Asia so the weather is relatively hot everyday except when it’s rainy days. Trying to find and search for ways to grow them at my area. Most of the roses here are grown in well, greenhouse as you said but I have read some blog that they grew in low land prettily as well. I’m actually planning to buy a few more to decorate my garden and hope I can take care of them well!

    @diane Im leaving the roses at semi shaded area where it’s getting half sun ☀️ daily. Every evening I’ll move the hanging pots back nearer to my house so that even if it rains in the middle of the night, my roses won’t get wet. I’m moving them every morning and night. I am worried it won’t survive rain water at such age.

    Is that your patio in Auckland?

    @rifis, I don’t live in Auckland

  • 4 years ago

    Yes! I now see that you don’t. Your comment thanking seasiderooftop was not visible to me when I asked about Auckland. Even though you had posted it prior to my query.

    I have commented on your other thread. I think you are battling against a climate which is unsuitable for these hardy, temperate climate plants.
