In Alabama, perennial clovers should be planted in the fall. Perennial clovers spend 5-6 months establishing their root systems. That's why there's not a lot of above ground growth during the fall and winter, like annual clovers. Come spring they will take off with a bang. Come summer with a good established root system, planted on soil that holds moisture, with some late afternoon shade, the clover should survive. Planted in spring, the clover doesn't have enough time to establish its root system before our hot dry summer comes. Yes believe it or not, there will come a time when it will stop raining.
