Newly planted roses have buds turning brown

[lbperera]

I have bought two David Austin roses from Bunnings two weeks ago. Planted them in pots. Both plant had buds at the time of purchase and they looked healthy. However, now the buds are showing some signs of browning and some young growth near the buds are also browning and crispy dry. What might have caused this and how to resolve the issues. Should I remove all affected buds and parts? Some hint is really appreciated.

Hello @lbperera 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your rose buds.

The browning and crispy dryness on the buds and new growth of your David Austin roses could be due to transplant shock, environmental stress, or early signs of pests or disease. Transplant shock is common when moving roses from a nursery to a new environment, as the plant adjusts to different light, soil, and humidity levels. During this period, buds may dry out as the rose redirects energy to establishing roots. Ensure the pots are in a sheltered location with partial sunlight, as direct sun or strong winds can exacerbate the stress.

Consistent watering is also crucial water deeply when the top inch of soil feels dry but avoid overwatering. Dry conditions and low humidity can contribute to browning, so a light misting may help, but avoid wetting the buds and leaves too much to prevent fungal growth. If you suspect pest or fungal issues, consider using a gentle treatment like Yates Rose Gun Black Spot & Insect Killer, which targets both pests and common rose diseases.

It’s best to trim off any affected buds and severely damaged leaves to encourage healthy growth and prevent disease spread. Additionally, feeding your roses with a balanced fertilizer like Yates Dynamic Lifter Organic Plant Food can help boost resilience and support new growth. With these steps, your roses should have a better chance to recover and thrive.

If you need further assistance, pleat me know.

Thanks for your message EricL. Could you please refer this to query to any other experts within this forum for alternative opinions? Thanks.

Good morning @lbperera looks like a bit of transplant shock, that’s quite normal. Photo number 5 with the perfect holes cut out are from Leaf Cutter Bees, that’s fantastic you have them in your garden as they are collecting leaves for their nests. They are Australian Native Bees. 
Have the flower buds opened up now ? 
I personally would just give them Seasol as it’s a tonic and really helps with transplant shock. 
When you have time, could you please share some photos of the whole plant including the pot it’s planted in and what type of potting mix you used. Good luck 😀🌿

Also I agree with the great advice Eric has given

It's great to see that one of our gardening experts, @mich1972, has responded to your questions @lbperera.

I'd also be keen to know if the buds are starting to open. I'd agree that it's likely some transplant shock. You could remove the buds if you wished, and this might help the plant focus on recovering.

Please let us know if you have any questions.

Thanks for your response. I removed those affected buds, canes and leaves. This was nearly two weeks ago. However, I feel still the plants are not performing at their best. Please see the photos attached. What is the cause of affected leaves? Any ideas would be greatly appreciated.

Have you beeen spraying anything over the leaves @lbperera?

Yes I’ve spayed Charlie carp foliage feed and macozeb plus.?

[MitchellMc]

The brown spots could quite possibly be from the Charlie carp as it is brown in colour @lbperera. I am uncertain whether Mancozeb would dry white. Let me tag @Noelle to see if it might be some other affliction.

Hi @lbperera and @MitchellMc 

Mancozeb Plus contains wettable sulphur which can leave a whitish deposit on sprayed leaves. I'd agree that transplant shock and Charlie Carp residue are the most likely causes of the other markings.

The roses have only just been planted out, so environmental conditions are unlikely to have affected them in that short period of time.
