Our trumpet creeper was doing real good this spring and produced an abundant number of flowers. But these last few weeks we noticed the leaves started turning yellow. We have had a pretty good amount of rain this spring but now summer is upon us. We have had the plant for two years and it has done well until now. It is in our courtyard located next to a large (18 inches high and six feet wide) planting wall. It receives full sun all day long. We do not see insects feeding on it. Our soil is high in lime due to this area being a limestone bed. Thanks for your help.

There are several reasons why a plant gets yellow leaves. Typically, it is a water or fertilizer issue. Making sure that it is getting the right amount of water and is fertilized (especially with iron) is a first step. Likely if you've had lots of rain, this could be the issue and will clear up on its own once the soil has dried out some.
