I just joined this forum today.
I am very new to roses.
All of my roses are newly planted this spring.
I have no idea what the names of my roses are or what type.
I just buy them and plant them because I like the color.
It is August here in Indiana and it has rained a little this month so far.
Possibly an inch over all.
I have a question about my roses.
1) I have a blue/lavender colored rose that has been planted about 4 months.
The rose has done well since planting.
Last week I noticed that leaves on this rose was turning yellow/green on the older leaves.
The new growth will start out red then will quickly turn yellow with the edges the red color.
I have looked up the problem on the internet and got several possibility's as to what the problem my be.
Calcium deficiency, potassium deficiency or possibly nitrogen deficiency.
It was suggested to add Boric acid, bone meal or nitrogen.
I have added a picture of this rose.
It produced buds and bloomed OK for a new plant.
All of the other roses in this garden are looking good.
Any help with this problem would be greatly appreciated.
