Another drawback from overseeding is the fact that pre-emergent herbicides cannot be applied for winter weeds before the lawn is overseeded, as it will kill the grass seed along with the weed seeds. On the other hand, if your client wishes to have a green lawn year-round or experiences a good deal of traffic during the winter on their turf, overseeding can be appropriate. If a homeowner wishes to let their previously overseeded yard lay fallow, pre-emergent herbicide should be applied to ensure both the winter weeds and ryegrass seeds do not germinate.

Transitioning the lawn back Ideally, perennial ryegrass will disappear on its own as the Bermuda grass greens up, but inconsistent spring and early summer weather can allow it to either hang on for too long or die off before the Bermuda can grow in. Repeat the fertilization and water cycle to stress the ryegrass.

The best time to overseed a Bermuda grass lawn is during spring. This timing is appropriate for most warm-season turfgrasses because it is the best for optimum growth of grass seed due to the favorable soil temperature.
Always overseed with the exact same variety for uniformity. Overseeding Bermuda with a cool-season grass variety is also recommended during winter. Read on for an elaborate guide on when and how to overseed your Bermuda grass turf; as well as the types of grasses to overseed with.
This time of the year is usually the peak growth season for Bermuda grass and other warm-season grass species. In spring soil temperatures are usually warm enough to facilitate Bermuda seed development. The absence of freeze and frost at this time of the year means that seed germination is unlikely to be hampered when planted then. Frosty conditions can kill Bermuda seeds. The other reason why you should plant Bermuda seeds during the peak growth season spring-summer is that planting before or after this time window can slow down the germination rate.
For example, Bermuda grass seeds planted in mid-spring under the perfect conditions will take less than a full week to germinate. However- when planted under unsuitable conditions say, early fall — Bermuda seeds may take up to three weeks to germinate and even longer than that to be fully developed weeks.
This is the minimum duration required for Bermuda grass underground shoots rhizomes to fully mature. To plant new grass seedlings on an existing Bermuda lawn, you first need to prepare the lawn area by coring. This should be done some weeks before overseeding. After prepping the lawn, you can then broadcast the seeds in multiple directions using a rotary spreader. You can set the spreader to release just a few seeds at a time, as you move through the lawn.
After that, you can drag the seeds to the soil level using a rake. You can overseed your lawn with a similar Bermuda grass seed if you want to keep things uniform.
However, for a dense, green Bermuda lawn all-year-round, you might want to consider a grass mix to help complement the shortcomings of this grass variety. Since Bermuda is a warm-season grass variety, you can avoid having to live with a landscaping eyesore during winter by overseeding your Bermuda lawn with a cool-season grass species, including annual ryegrass and perennial ryegrass. While annual ryegrass seeds are cheaper, this species has poor heat-resistance and dies out by mid-summer.

Seed mixes consisting of 80 to 90 percent by weight tall fescue and 10 to 20 percent Kentucky bluegrass seem to work well. Use Kentucky bluegrass and perennial ryegrass in areas that receive irrigation. The best thing you can do to maintain a healthy zoysia lawn over winter is to overseed and use a cold weather grass type for the winter months.
The cold weather grass usually tall fescue will spring to life in winter and let the zoysia rest, only to go dormant in summer when your zoysia comes back to life. Bermuda and Centipede are two popular warm-weather grasses that are commonly used in lawns. If allowed to grow unchecked, Bermuda grass will overtake or choke off Centipede grass.
Unless it is completely removed, which is difficult, Bermuda grass will keep coming back. Bermuda grass grows in U. Department of Agriculture plant hardiness zones 7 through 10, while centipede grass grows best in USDA zones 7 and 8. Bermuda grass does not tolerate shade as well as centipede grass and other warm-season grasses ; centipede grass may succumb to salt spray and a lack of iron in the soil. While Bermuda seeds are less expensive, St. Augustine sod gives you more instant gratification.
The maintenance for St. Augustine grass is high and requires regular mowing, fertilization and irrigation, while Bermuda grass requires less maintenance and can grow thicker with more frequent mowing and irrigation. Can you mix Bermuda grass with Zoysia?
