Hi

I am new to gardening and was captivated by the colorful flowers of Gaillardia. I purchased a pot from an online store located in suny, dry CA. I planted them last week in a sunny (west facing) location, added reasonable amount of compost to make the sticky clay soil of Northern VA a little more well-drained. This week I observed that the lower leaves of the plant have starting getting yellow. I have not been watering the plant much as I read online that the plant prefers dry, well-drained, poor soil.

Not sure if I am doing anything wrong for the plant or is this just an adjustment phase for the plant as it adapts to the new conditions.

Will really appreciate insight from someone who has successfully grown these beautiful plants in clay soil. Thanks in advance
