I just happened to read the FAQ on this at the Iris Forum this week. It could be any number of things it seems. I have no bloom on my bearded irises. Why are they not blooming? Next............ Sue

Hello, heckabore. Normally, pruning after the rhodie has set flower buds would cause your problem. However, since it has not been pruned in 5-6 years, something else is causing the problem. Do you mind answering some questions? How close is it planted in relation to the other plants, shrubs and/or trees? Can you give us an idea in terms of plant types and inches/feet of separation? Has the plant ever bloomed... at all? Do you have flower buds now or did the plant not even set buds at all? If it has buds, how do they look? Healthy? Are they browned out? Do they look like they have hair covering them? (That is a sign of a fungal infection.) Do you have animals that could eat the flower buds in your city? Deer and squirrels have been known to eat the buds in some locales. If the plant is not developing buds, how much and when do you fertlize? Could it be getting too much nitrogen directly (when you fertilize it) and indirectly (from lawn fertilizers)? Normally, you do not need to fertilize rhodies as they feed off the decomposing mulch. But if you have to fertilize due to poor soils or because it is in a pot then the plant could stay busy in growing mode if you apply fertilizers after July or so. July or so is when the plant begins developing flower buds for next year. Cold weather can be issue but I doubt it would be THE issue for so many years in Zone 9. Moreover, I would have expected it to be an issue for the azaleas too. Very wet conditions could also cause problems during summer so let us know if you normally have cool wet summers. Lack of sun can also be an issue although I would be suspicious of that if the nearby azaleas are blooming as well as you say. Is the plant suffering from moisture issues at the time it is developing the flower buds (July-August)? This could be an issue to nearby azaleas but it surprises me that all of them are doing ok. How much and how often do you water during the summer? If they are drowned in water during this critical time, they may be unable to develop buds. Ditto for lack of water. Soil Ph might be an issue too but it would have affected the other azaleas. Lack of certain micro nutrients in the soil can trigger this behaviour in rhodies but, again, I am surprised that the nearby azaleas have not been affected. When was the last time that you had a soil test? Lastly and this is not a cop out, I have heard of some varieties of rhododendron that never bloom but I doubt yours would be if the label showed otherwise. People buy them for the foliage. Of course, you did mention that the missing plant label indicated otherwise. If we cannot figure something out, do not feel obliged to keep this weak specimen. Some plants like roses (Queen Elizabeth for example) sometimes bloom poorly or not all. Luis

I don't keep anything in pots so it may be a little different. irises don't need a lot of fertilizer. I usually fertilize after bloom. True for most flowers - nitrogen gives you green, phosphorus gives you blooms. Little bit of of miracle grow for blooms should do it. Any balanced fertilizer would work. They aren't all that fussy and really do better in soil that's on the poor side.

Unless they are a reblooming cultivar, they will only bloom once per growing season. You might check them, though, to see if they still have any unbloomed buds on the remaining stalks. It's possible they might not be done yet. Laurie
