These are out door 11 Roses in a buildasoil 3.0 mix in a 32 inch tall 42 inch wide birdies metal raised bed. My lowest leaves are showing burning and rust/yellow coloring. But as you move up the plant it goes away and everything looks fine.
I also have 4 other plants, different strains, in the same soil mix showing no problems. Is there anything I can do, should I just ride it out?
Since my other plants seem to be fine I figure the problem is either the metal raised beds, as my other plants are in wooden raised beds. Or this strain is sensitive or has additional nutrient requirements.
Any diagnosis or advice would appreciated.
