I don't know much about rhododenrons and I just started noticing my plant needs some help, whether it's fertilizers or it's got some mineral deficiencies.
The leaves on my rhodo seems to be yellowing somewhat although it's still green. The leaves are not veiny. It has lots of buds and is about to bloom. It's not suffering from anything else. It's presently planted against a west facing wall(light shade and part sun), in clay soil that's been ammended with compost and composted manure. I don't do much chemical fertilizing. Yesterday I just added some peat to the soil.
I would appreciate any advise on what to do. If recommending fertilizers, could you recommend specifics ratios - rather than brand name because I'm located in Canada and any brand name in the States may not be avail. up here.
