| My crape myrtle was doing fine until a few days ago. The nearest city I'm in is Nashville/Memphis. I've noticed there wasn't much sun and the crape was almost like an understory. Now some blossoms are coming out white/light pale pink rather than purple/ lavender. |

| So the weirdness of which you speak is a change in bloom color? |

| Normally the cause is not enough sunlight-- either due to location or even extended cloudy weather. There are other possible causes. "Crape myrtles need full sun to perform the best, grow the best and bloom the best. This means eight hours or more of direct sun daily. Many of us underestimate the amount the amount of sun that our landscapes receive. Check sun patterns in the morning, during the middle of the day and during late afternoon. Soil pH is important for crape myrtles, but maybe not as important as it is for some of our other landscape plants. Crape myrtles like a soil pH of 6.0-6.5. This is considered slightly acid. Do not guess on soil pH � soil test. Lower pH with sulfur products and raise pH with lime products, but always do this based on the results of a soil sample." - LSU Ag Center See also articles by "The Grumpy Gardener" at Southern Living's website. Also, Crepe Myrtle plants can often be mislabeled at time of sale (if this is a newer planting) as is common with high-volume plants with multiple variants. |

| We have had two abnormally cool, cloudy summers in a row where most of our crape myrtles didn't bloom at all. They budded out and then the buds didn't open. We saw this all over the county, as they are used as street trees in some of the cities. So sunlight definitely makes a difference! |
