Zoysia grass is a warm-season grass native to the Northern Hemisphere. It is a tough grass that spreads quickly through rhizomes and stolons. It requires little care. When frost hits in the fall, however, it goes dormant and almost immediately turns brown. If you have a trouble spot in your lawn, you may want to try this type of grass. Knowing how to harvest these seeds will help you plant areas of your lawn inexpensively.
Take care of your zoysia grass as it produces seed spikes. Do not mow during this time. Water the lawn and fertilize appropriately. Seed spikes should emerge, growing above the rest of the lawn in June or July.
Allow the seeds to turn a golden brown color as they ripen. Pinch the seed heads off the spikes or cut them with shears.
Place the seed heads in a paper bag. Allow them to dry for three to four weeks. Shake the bag every day to stop the seed heads from sticking together.
Separate the seeds from the spike after they have dried completely. It may help if you roll the seed head between your hands. Place the seeds in an airtight container to store for the year.
