Answer 1

There may be a mild iron deficiency. When planting in pots, you need a fertilizer that has micronutrients as well as NPK. How long has the rose been in this pot and what type of rose is it? Except for miniature roses, they often don’t thrive in pots. A shrub rose that gets 3+ feet high and wide needs a much larger pot. I suggest you shift to a long-acting granular fertilizer with micronutrients. 20-20-20 is pretty strong stuff and you run the risk of burning the roots as well as getting too much P&K, especially if you are using a liquid fertilizer.

Answer 2

Thanx for your answering.
I’ll feed the plant with iron
I Bought that as a miniature rose and it’s about 3 month in that pot
But the original pot of the plant was too smaler than this one.
Is this one still small?
Can i change it again now in spring or i should wait until winter?
Best regards

The present pot should be fine. Remember that potting mix breaks down and plants needs to be renewed by repotting every few years. To keep the plant in this container, you may want to prune the roots when repotting. I’d repot when the plant is dormant; it will be much less stressful to the rose.

Thx for attention.
So every year i will change that pot with one size bigger when the plant is dormant
