Yellow spots?

[Kittykicker]

Yellow spots normaly means that there is too much water. Will the leaves go back to normal or do I have to take the yellow leaves off?

Yellowing is generally a nitrogen deficiency from my experience. You shouldn't have to remove the leaves.

Cultural management is generally sufficient to keep these diseases in check. Leaf spot fungi overwinter in and produce spores for new infections on the fallen leaves, which should be gathered in the fall and removed from the site or destroyed. Infection occurs when leaf surfaces are moist; improve air circulation by thinning crowded plants and pruning overly dense growth. Avoid overhead irrigation, or water only in the morning to ensure leaves dry quickly
