| I recently planted these CM's and noticed today several have red leaves with black spots. I searched online in an attempt to diagnose and treat to no avail. I have many CM's (Tonto, Sioux, Muskogee, Pocomoke, to name a few) and have never see red leaves with black spots. ALso, some yellow leaves with spots. Please help. |

| When you say you recently planted them, do you mean now, in some of the worst heat of the year??? Just how long have they been in the ground and how are you taking care of them (watering, etc)? Do you have pictures you could post? |

| Brandon, yes, these were planted a few weeks ago, very small - about 8" tall, healthy, and one plant already has a few blooms. Yes, it is hot, but they have been watered and watched every day and hae shown no sign of stress or wilting. They actually look beautiful except for the few red and yellow leaves with the black spots. I will take a few pics and post, but what is up with the red leaves? Lack of a nutrient? Sure hoping it is not Cercospora or I will be returning them to the nursery. Will post pics later today. Thanks. |

| The red leaves are most likely a sign of stress. Could it be disease? - That's possible, but unlikely if they were in good shape when you got them. Lack of nutrients? - Nope, forget that one. Watering every day? - Should only be done if you have very very sharply draining soil. You really need to test soil moisture (down a few inches below the surface) to determine when to water. Longer (deeper), less frequent watering is much better than shorter (quick), frequent watering. Post some pictures AND tell us about how your crapes were planted (especially details about planting depth, root preparation, and soil amendments used). The link below may also be helpful with future planting endeavors. |

| As to "watering everyday?" Is often an excellent idea for recently plants trees and shrubs and more. Not at all related to soil drainage at this time in the plant's life. The reason: the rootball dries out VERY rapidly and needs water more often than the surrounding soil. Apply directly to the rootball! |

| "Not at all related to soil drainage at this time in the plant's life." Sorry, but that statement is absolutely 100% totally incorrect! More frequent watering is indeed often necessary for newly planted trees with limited root systems, which may not be able to reach sufficient moisture when the soil dries out too much. However, drainage (including the drainage of the surrounding soil) is highly important! Trees can die from over watering as easily as from under watering. Insufficient drainage coupled with consistently wet soil can certainly kill a newly planted tree. |

| ...make that tree or shrub. |
