Summer care for roses

[Mustansir Billah]

JazakAllah Umar sb.

Mustansir sb, may also consider changing the pots. In my view these are too small to support good growth for two years bush. Cramped roots invite trouble and plants will keep getting sick. Ideally, roses should be planted in ground but I see that you don't have that option. For good growth, two years old bush would need 2*2 ft space with a well prepared potting mix having good drainage. Increasing pot size will help, IMHO.

I have changed the pot and now thay are in 20" pot and hoping for the best.

Can I pour Fungicide to the soil?

[Mustansir Billah]

I have poured fungicide (sulphur) mixed with water and sprayed it on roses and Now black spot disease is IMO completely gone but I forgot to wash the bush after the application of sulphur due to which my one rose has died because of leaf burn. Now I have washed it and hoping for the best.

For blackspot, pluck disease leafs. and BURN them. or dispose them very far. And if you want to spray, I suggest copper-fungicides- copper oxichloride is easily available under many brands. Sulfur in my experience, like you have mentioned causes burning to some roses with delicate leaves, or those with less glossy leaves. Sulfur is good if u have fungus AND mites, because it does have some miticide activities.

Keep roses in shade for now. Karachi is expecting rain this week inshallah, or so says BBC weather. Let's hope this heat ends!

Where this copper oxychloride is available in Karachi? And Yes! with this rain rain this heat will end and fall will begin.

[dragoonsers]

It should be available either under the STEDEC brand "Copxikill" or simply Copper Oxichloride at the shops near old sabzi mandi (KHI).

Ok! JazakAllah

[Mustansir Billah]

Something troubling my roses. Bud eye fails to develop and I am sure it is not from summer heat because I had been only giving them 2 to 3 hours of sunlight only.
The brown color on leaves is of sulphur burn but I had washed it now and that is not troubling.


Even if the new leaves sprout then the bud wilts and fall.




And What is this?
