Perennial clover will self-seed too, but it spreads consistently through its creeping root system. Some perennial clovers will die back in hot or cold weather, but new growth will emerge from the roots the following growing season.
How long does clover take to spread?
When clover seeds are planted correctly on prepared soils, they can sprout in two to three days in the summer. Also, clovers take less than a week to germinate and sprout when temperatures are around 59 degrees Fahrenheit.
How do you encourage clover to spread?
Mix your clover seed with sand, sawdust, or fine soil to make spreading easier. Use a broadcast spreader (if you can find one that accommodates clover) for large areas to ensure even distribution. Do not fertilize. Follow with grass seed if using.
