Aerate and Dethatch Bermuda's dense, aggressive growth often leads to excess thatch. Aerate compacted soil and dethatch Bermudagrass as it enters peak growth in late spring and early summer.
Watering Once growth begins, water your established Bermudagrass lawn so it receives about 1 inch of water per week, including rainfall. Never remove more than one-third of the blade in a single mowing. During peak growth, Bermudagrass may need mowing more than once per week.
Fertilization Because of its aggressive growth rate, Bermudagrass requires regular feeding during peak growth. Watering Bermudagrass is drought-tolerant, but it will go dormant during periods of extended drought. Soil Testing Test your lawn soil every three to four years to confirm soil pH. Bermudagrass grows best with pH between 5.
Weed Control and Fertilization Four to five weeks before your area's typical fall frost date, feed your Bermudagrass lawn and treat broadleaf weed. Avoid all weed killers at least three weeks before overseeding. Watering Keep watering your Bermudagrass lawn with 1 inch of water per week. Gradually reduce watering as dormancy approaches. Soil Amendments Amend your soil based on soil test recommendations. Lime restores nutrient availability in overly acidic soils.
Gypsum helps loosen heavy clay soil and enhance root growth. Leaf Management Rake or mulch fall leaves so Bermudagrass gets plenty of air and sun. Mow green overseeded lawns to maintain cool-season ryegrasses at 2 inches tall.
Watering Water dormant Bermudagrass lawns only if needed to prevent desiccation during dry periods. Tool Maintenance Sharpen mowers and clean lawn tools to reduce the risk of lawn disease and be prepped for spring. Winter Weed Control Spot-treat green winter weeds. Let us answer all your questions on overseeding your Bermuda grass lawn! Overseed your Bermuda grass lawn too early in the year, and you could risk the cold-weather stopping the germination process.
Temperatures below zero will kill the seed. A Bermuda grass seed needs a warm environment in order to germinate because it is a warm climate grass.
Try overseeding your lawn too late in the growing season, and you may see the germination process stunted. Dry or cool conditions will slow the process down from one week to three weeks. Make sure to give a newly seeded lawn at least three months before overseeding. Newly seeded Bermuda grass will need this time to establish strong roots before competing with new seeds for space. The right soil temperature , moisture , and oxygen are all equally important for the seed to take root.
The soil should be around 65 degrees Fahrenheit. Make sure your lawn is well watered right after overseeding, but not waterlogged. Excess rain or watering may wash the new seeds away or stop them from getting the oxygen they need to germinate.
Another way to encourage new growth is to aerate your lawn before overseeding. This will help make sure seeds fall down into the soil, but still, get plenty of oxygen.
If you want to overseed without aerating, quickly go over your lawn with a large garden fork and stab some holes in the soil. Pro tip: Irrigate daily for 10 days after overseeding before going back to your regular watering schedule.
The germination process, once begun, actually takes less than a week in the right conditions. The patches of bare ground scattered through the seeded area can be quite unsightly. Early October provides excellent temperatures for good germination and growth of the young seedling plants. The winter grass to plant is ryegrass. You have your choice of either annual or perennial rye. Annual ryegrass seed is fairly inexpensive and germinates well. The grass will stay green well into the spring, only dying out when the heat of June arrives.
One of the benefits of planting perennial ryegrass is that, in milder climates, it will persist through the year from season to season. Because of the high summer temperatures in Pinal County, perennial ryegrass will usually die out completely, except in the shade, thus losing its primary benefit. Perennial ryegrass seed is also more expensive than annual ryegrass seed. The real benefit to perennial over annual ryegrass is that perennial forms have a leaf structure that is more fine and less coarse rather than the tall and lanky-growing annual ryegrass.
In short, many people feel that perennial ryegrass makes a better looking turf than the annual forms. It is your choice. When preparing to plant annual ryegrass, it is important to remember that the heat-loving Bermudagrass will most likely still be green at the first of October.
In order to ensure proper seed contact with the soil, it will be necessary to thin out the summer grass growth. Perennial grass stays green and wear-tolerant in winter as Bermuda grass lies dormant. To properly overseed your Bermuda lawn with perennial ryegrass, I recommend applying 15 pounds of seed for every square feet of lawn area.
Use a lawn seeder when overseeding your Bermuda lawn with Bermuda grass, as this will encourage uniform growth. Slit-seeding, aero-seeding, and broadcasting- on the other hand- are not recommended, as you may end up with random, unsightly perennial ryegrass growth patterns. To properly care for the perennial ryegrass after overseeding to encourage germination and greening, you should apply topdressing and fertilizer.
Meanwhile, a starter fertilizer not only boosts the growth and development of the perennial ryegrass, but also speeds up the recovery rate of your Bermuda turfgrass once spring comes around. Annul ryegrass- on the other hand- tends to die out as soon as the warm season returns in early spring.
Choose the grass seed to use for overseeding properly and then go ahead to overseed at the right time. Stop applying pre-emergent herbicides at least three months before you overseed, as the weed-killer will kill off your new seedlings as well.
Mow the lawn at a height of one-inch prior to overseeding. Also, rake the lawn to ensure increased contact between the grass seeds and the soils once you start sowing. Such proper lawn preparation is necessary if you want to increase your chances of ending up with a thicker, fuller turf. Overseed the lawn by sowing between pounds of grass seed for every square feet of lawn area. Sowing should be succeeded by watering and application of a nitrogen fertilizer to facilitate faster germination.
Once your new grass seedlings have grown to a height of about 2. This is usually at about the one-month mark post-overseeding. Continue mowing the turf every two-three days. Pro tip: For Bermuda lawns that undergo heavy foot traffic, using a sand mix topdressing helps to speed up the rate of turf establishment for the newly-planted seeds.
Overseeding in the fall is not recommended because the low temperatures usually inhibit seed germination.
