one clematis thrives, other no new growth but not dead

seagreen_turtle(Z5 MI)September 16, 2009

The thriving species is Jackmanii (purple) and the sickly looking is Niobe(fuschia). I planted over a month ago in very similar locations, they both came from a very good nursery whose plants tend to thrive. The Niobe has grown a lot and produced lots of new flowers. The Niobe is not dead but hasn't grown at all and the leaves are a bit ratty. Should I fertilize it a little even though it's fall?

The difference is because Jackmanii is a Type III and Niobe a Type II. Type II's typically get off to a slower start than III's. III's are usually more vigorous in general. Getting lots of flowers the first year isn't typical though of any clematis. They are first year sleep, second year creep and third year leap plants.

I would not fertilize in your zone at this time.

Cut them both back to the last set of buds in early spring when you cut back roses in your area. Then fertilize them.

Thanks buyorsell888. The Jackmanii is flowering like crazy (second flush). When I bought it and planted it in early July, it was flowering (they both were - the Niobe too I mean). I will keep my fingers crossed for the Niobe for next spring. Thanks again.
