Thanks luis for the reply, honestly much appreciated.
As for my roses are infected with Rose Scale, I still would not exclude that cause, and I will be able to check that only on Thursday, as I live in another town Ã¢â‚¬â€œ different than where I have planted the roses. And on Thursday will visit my roses to examine.
I have done some quick googling on Rose Scale and I know what to look for on the stem (Thanks for the tip)
As for the weather and systematic rose maintenance, well I do try to maintain them, but maybe not very systematically.
I do mulch them, I do spray coffee ground that I get from Starbucks around the base, I do mix cow manure, coffee ground and peat moss and place it around the plant base.
Soil testing, well I do have a PH tester and my soil seems to be neutral (neither Acidic nor Alkaline).
For your information I have over 24 Rose plants, some of them recently planted a week or less ago, some of them have completed two years since planted, I will have to record the maintenance I do to them.
A piece of additional information: I have a millingtonia (Indian Cork) tree planted close to my roses, and that millingtonia have spread its roots almost all over the place,around the roses. Everytime I dig around the roses I see the roots of that mellingtonia. Its root is very shallowish. But I can not and will not get rid of that millingtonia either, as it is adorable tree.
What NPK composition I should use to give good growth especially foliage. I need the foliage more than the roses for the time being.
Appreciate the comments
