These two newly developed white clovers persist well in grazed Georgia environments and offer excellent potential to improve both animal performance and pasture quality. Plant clover in the spring or early summer, when the ground has become soft and moist from the spring rains. Applying clover seeds in clumps will cause the seeds to compete with each other, which will slow down establishment time. Their germination and sprouting times are dependent on soil preparation and proper sowing methods. In the absence of a soil test and assuming a medium-fertility soil, apply -60-145 lb per acre. Lime is necessary to bring the pH of the soil up to the neutral range (6.0 to 7.0 for the best performance). If you must till or plow the soil before planting, be sure you wait 4 to 6 weeks for new weeds to emerge so you can kill them before planting the clover seed. White clover interseeded into toxic tall fescue pastures can reduce intake of these toxins and improve animal performance. The temperature should be around 30-50 degrees Fahrenheit at night. Also, clovers take less than a week to germinate and sprout when temperatures are around 59 degrees Fahrenheit. As you can imagine, planting and watering clover plants seem easy enough.
