Perennial Ryegrass Lawn Maintenance Schedule – As with other cool-season grasses, perennial ryegrass grows most strongly in the autumn and spring. During the summer months, it stops development or turns dormant on permanent northern lawns. To maintain the optimal appearance and performance of perennial ryegrass, schedule your yearly lawn care duties to coincide with these natural cycles.
- Within the vast growth range of perennial ryegrass, climatic circumstances might fluctuate considerably from year to year; thus, let your lawn direct your scheduling from year to year.
- Consult a county extension agent if you are unsure of the average frost dates and planting schedules in your region.
Then, follow this maintenance schedule for perennial ryegrass to maintain a healthy and attractive lawn. MARCH THROUGH MAY Mowing Start mowing as the grass begins to grow. Maintain perennial ryegrass at a height between 1 1/2 and 2 1/2 inches to promote dense growth and an attractive appearance.
To prevent the spread of winter fungal illness, collect the season’s initial cuttings. Prevention of Weeds and Fertilization Fertilize your perennial ryegrass lawn in early spring to prevent crabgrass growth. Apply Pennington UltraGreen Crabgrass Preventer Plus Fertilizer III 30-0-4 prior to the soil reaching 55 degrees Fahrenheit and the germination of weed seeds.
Do not apply to newly sown or reseeded areas within 60 days. Seeding and Overseeding Similar to other cool-season grasses, perennial ryegrass germinates best between 50 and 65 degrees Fahrenheit. Spring is the second-best season to sow lawns with Pennington Smart Seed Grass Seed + Fertilizer Perennial Ryegrass, after the autumn.
Herbicides and Fertilization In the late spring, when both grass and broadleaf weeds are actively growing, use Pennington UltraGreen Weed & Feed 30-0-4 to fertilize your existing lawn and to manage emerging broadleaf weeds. Do not apply to newly planted areas until at least three mowings have occurred.
At least three weeks must pass between application and reseeding. Watering Your established perennial ryegrass lawn requires around 1 inch of water each week, including precipitation. Irrigate extensively and thoroughly to promote deeper root development.
FROM JUNE TO AUGUST Mowing During seasons of heat and low precipitation, up the cutting height to 3 to 4 inches. Mow often enough to never remove more than a third of the blade at once. Fertilization Pennington UltraGreen Lawn Fertilizer 30-0-4 should be used to perennial ryegrass lawns. Watering As needed, supplement rainfall with irrigation so that perennial ryegrass receives between 1 and 1 1/4 inches of water per week.
Control lawn-damaging insects, such as grubs and beetles, using Sevin Lawn. Granules of insecticide Early pest management reduces property damage and avoids new generations of pests. Soil Analysis Every three to four years, you should do a soil test to validate the pH and nutrient content of your lawn’s soil.
The optimal pH range for perennial ryegrass is 5.5 to 7.5. In regions with very acidic soil, such as portions of the Pacific Northwest, lime may be required to restore nutrient availability in your lawn. SEPTEMBER THROUGH NOVEMBER Mowing As autumn temperatures approach, gradually reduce your mowing height to 1.5 to 2.5 inches.
Continue mowing your perennial ryegrass lawn until it stops growing. Herbicides and Fertilization Utilize Pennington UltraGreen Winterizer Plus Weed & Feed Fertilizer 22-0-14 to kill broadleaf weeds and nourish established perennial ryegrass lawns six to eight weeks prior to the first frost in your region.
Use Pennington UltraGreen Lawn Fertilizer 30-0-4 to spot-treat invasive weeds and Pennington UltraGreen Lawn Fertilizer 30-0-4 for overseeding. Seeding and Overseeding The optimal time to sow cool-season grasses, including perennial ryegrass, is in early autumn. Pennington Smart is utilized to sow northern lawns.
Plant Perennial Ryegrass 45 days before to your region’s average first fall frost. When the warm-season grass begins to fall dormant and become brown and the nightly air temperature drops to between 65 and 70 degrees Fahrenheit, overseed southern lawns for winter color.
Watering In northern lawns, reduce watering gradually. As necessary, supplement rainfall so that perennial ryegrass receives 1 inch of water every 10 to 14 days. Continue frequent watering in southern lawns so that perennial ryegrass receives one inch of water each week. Aeration and decompaction As needed, aerate soil that has been compacted.
Typically, perennial ryegrass that forms clumps does not create a substantial amount of thatch. Leaf Management Rake or mulch fallen leaves so perennial ryegrass enters winter without a layer of leaves. DECEMBER THROUGH FEBRUARY Southern Garden Upkeep Mow and water perennial ryegrass in warm-season, dormant winter lawns according to a scheduled care plan.
- Northern Lawn Services Clear your grass of winter detritus.
- As the soil thaws in late winter, flush damaged areas caused by de-icing salts or pet urine.
- Maintain mowers and grass equipment for spring readiness.
- Perennial ryegrass can offer the required speed, vigor, and color for applications in the north or south requiring a fast-establishing turf grass.

What is the optimal planting month for rye grass?
Rye grass fleur de lis In this 2007 photo from the collection of The Times-Picayune, 80-year-old longtime season ticket holder Edgar Cretin of Covington trims the huge fleur de lis he recently planted from winter rye grass seed in his front yard. (Chuck Cook, archive of The Times-Picayune) When is the best time to plant rye grass seed? Will perennial rye grass return in the fall if I sow it? Timothy Vincent.
- October and November are optimal planting months for winter rye seed to stabilize soil in regions with poor lawn grass coverage or freshly filled areas.
- Existing lawns can also be overseeded with rye to extend their green hue through the winter.
- Remember that this extends the time required to mow your grass.
There are both annual and perennial ryes available. The most widely accessible and least cost grain is annual rye. The grass produced by perennial rye has a finer texture, richer green hue, and requires less frequent mowing. However, the seed is more costly.
Establishing Winter Rye Winter rye is an excellent choice for a cover crop, which helps maintain the health of a garden. Winter rye is an autumn-planted cereal crop in vegetable gardens. As with other cover crops, planting winter rye is one of the greatest ways to develop soil.
Learn how to sow winter rye and why you would want to do so. Why is planting winter rye in gardens so beneficial? Cereal grains such as winter rye emerge rapidly from seed to produce a thick mat that covers the earth. This living ground cover suffocates weeds in the chilly season. A dense ground cover also helps minimize soil erosion and nutrient loss during the winter months.
Winter rye is a deep-rooted plant. It is a fantastic choice for clay or heavy soils that require more aeration due to its high growth rate and its ability to send roots deep into the ground. Additionally, winter rye with its extensive root system takes nitrogen and minerals from deep under the soil and transports them to the leaf blades.
- When you cut down winter rye in the spring and till the leaves into the soil, the nutrients are returned.
- Winter rye planting dates vary by area, but it is the most cold-resistant cover crop, thus it may be planted as late as October.
- The rule of thumb for cover crops is to include them into the food garden once all other plants have been harvested.
Depending on where you garden, you may sow winter rye between August and October. In zones 6 and milder, winter rye is planted in late autumn; in the coldest zones, it is planted in early autumn. After sowing winter rye seeds, they germinate and flourish.
In warmer regions, you will likely need to mow winter rye many times. If severe frosts occur, plants will go dormant until spring, when growth will restart. At this point, you can cut the rye many times, or you can wait until it reaches a height of around 12 inches and cut it once. Depending on the height of the winter rye, use a lawn mower, string trimmer, or scythe to cut it.
Most cover crops are tilled into the soil after being harvested in the spring, contributing nutrients and organic matter. Cover crops are referred to as green manures because they provide the same function as manure in soil. Winter rye stems are robust enough to be used as a loose mulch in a vegetable garden after being chopped.
How late may ryegrass be planted?
Annual ryegrass seeding as a Midwest cover crop – Annual ryegrass seeding as a Midwest cover crop is a relatively recent technique. There are a number of planting management choices that will influence the risk and chance of a successful endeavor. The optimal period to sow annual ryegrass is between the middle of August and the end of September.
Mid-October sowing is feasible, although more weather-dependent, particularly in the Central Corn Belt. Annual ryegrass will sprout in 7 to 10 days if the soil is sufficiently wet. A lack of moisture in the soil will impede germination and early development. Ideally, annual ryegrass requires 60 days of development before a severe frost kills it.
A dormant sowing between December and February is also possible (but not the preferred method). Way and depth of sowing — The best method for sowing annual ryegrass is using a no-till drill (main box would suffice) around 1/4 to 3/8 inches deep. This ensures proper interaction between seed and soil.
- Other approaches include combining seed and fertilizer with airflow or spreading fertilizer with a fertilizer spinner.
- After blowing or disseminating, running a fluffing harrow (such as a Phillips or Phoenix) will increase seed distribution.
- However, dry soil will hinder germination and early development.
Annual ryegrass seed is lighter than fertilizer and will not be dispersed as far using a spinner because of this (will need to split the middles to get uniform application). Aerial seeding (airplane or high-boy sprayer with electric-motor spinner) into a standing crop of beans and corn immediately before to leaf drop as leaves dry.
- This approach establishes the cover crop early, but without rainfall, the results may be poor.
- Some of these seeding methods are more effective than others, but they are all effective (with rain).
- In dry soil conditions or when sowing in October, however, it is strongly suggested to utilize a drill.
- Annual ryegrass is typically sown at a rate of 10-15 lbs/acre.
Increase the seeding rate to 22-25 lbs/acre when aerially seeding or using a dormant seeding and 18-25 lbs/acre when broadcast seeding or planting in October. Use the 15 lb/acre setting recommended for tall fescue when establishing drills to sow annual ryegrass.
- This is 20 pounds per acre of annual ryegrass.
- Before planting annual ryegrass, a burndown herbicide should be sprayed if winter annuals are present at the time of planting.
- If winter annuals germinate before sowing annual ryegrass the following spring, they will compete fiercely with annual ryegrass.
Nitrogen – Depending on soil conditions, you may apply up to 50 lb/acre of Nitrogen (DAP is effective) to boost autumn growth. This is especially critical for October planting. If properly planted (instructions above followed), one should expect to see 2-4 inches of top growth before a harsh cold kills it.
