If you are looking for a grass type that can handle the cool and wet climate of Oregon, then you might want to consider Perennial Ryegrass and Kentucky Bluegrass. Both of these grass types are commonly used in the Pacific Northwest and can provide a lush green lawn with a fine texture.

Perennial Ryegrass is a cool-season grass that is known for its fast germination and establishment. It has a shallow root system and can be easily damaged by drought and heat stress. However, it can recover quickly from damage and can provide a dense and attractive lawn. Perennial Ryegrass is often used as an additive to bulk-up other slow-growing grasses and can be mixed with Kentucky Bluegrass for a more resilient lawn.

Kentucky Bluegrass, on the other hand, is a slow-growing grass that is known for its rhizomes, which help it spread and fill in bare spots. It has a deep root system and can tolerate a wide range of soil conditions. Kentucky Bluegrass is less susceptible to heat and drought damage compared to Perennial Ryegrass. It can also handle more muddy conditions and is much more likely to hold in place.

When it comes to watering, Perennial Ryegrass requires only 1″ of water per week, which is about average for most turfgrass species. Kentucky Bluegrass can tolerate slightly drier conditions and can go up to two weeks without water. However, it is important to note that both grass types require well-drained and moist soil for optimal growth.

When it comes to seeding, Perennial Ryegrass is known to be a rapid germinating grass type, while Kentucky Bluegrass is very slow to germinate. If you are looking for a quick establishment, then Perennial Ryegrass might be the better option. However, if you are willing to wait for a more resilient lawn, then Kentucky Bluegrass might be the way to go.

Overall, Perennial Ryegrass and Kentucky Bluegrass can provide a beautiful and resilient lawn in Oregon’s cool and wet climate. Consider mixing these two grass types for a more robust and attractive lawn.

Fescue Varieties: Fine and Tall

https://www.youtube.com/watch?v=CWvkilKyXJg&embed=true

If you’re looking for a grass type that can thrive in Oregon’s cooler and wetter climate, fescue is a great option. The two main types of fescue are fine fescue and tall fescue.

Fine fescue is a group of grasses that includes creeping red fescue, chewings fescue, hard fescue, and sheep fescue. These grasses are known for their fine blades and bunch-type growth habit. They are also shade-tolerant and require less fertilizer than other grass types. Fine fescues are great for low-maintenance lawns that don’t see a lot of traffic.

On the other hand, tall fescue is a bunch-type grass that has broader blades than fine fescue. It has a deep root system that makes it drought-tolerant and able to withstand heavy traffic. Tall fescue is also more tolerant of acidic soil than fine fescue.

For general turf on sunny sites, a mix of 70-80 percent perennial ryegrass and 20-30 percent fine fescue will make a lawn that is rugged, will tolerate some shade, requires medium to high fertility initially to look good, and is fairly easy to cut. When overseeding, sow 2 to 2 ½ pounds of grass seed per 1,000 square feet for fine fescue, and 4 pounds per 1,000 square feet of lawn for turf type tall fescue.

Overall, both fine fescue and tall fescue have their strengths and weaknesses. It’s important to consider your lawn’s needs and your own personal preferences when choosing which type of fescue to plant.

Bentgrass: Colonial and Creeping

https://www.youtube.com/watch?v=FM5bYB5u3P4&embed=true

If you’re looking for a grass type that can provide a beautiful, high-maintenance lawn, then bentgrass may be the right choice for you. There are two types of bentgrass that are commonly used for lawns: colonial bentgrass and creeping bentgrass.

Colonial bentgrass is a great choice for lawns that are mowed fairly short and at least once per week. It provides a quality surface at mowing heights between .38″ and 1″. Some of the newer cultivars even look good as high as 1.5″. However, at 2″ and above, turf quality declines, and false crowns and scalping occur from late summer on. Colonial bentgrass is also used on golf course fairways and putting greens.

Creeping bentgrass, on the other hand, has above-ground creeping stolons and is best suited for golf course putting greens and tees. It can be mowed very close to the ground, spreads quickly, and makes beautiful lawns, but it requires high maintenance. Creeping bentgrass is not recommended for lawns in Western Oregon.

Both types of bentgrass can be used for lawns, but colonial bentgrass is the better choice for most homeowners. It is more tolerant of shade and disease, and it requires less maintenance than creeping bentgrass.

Overall, if you’re looking for a grass type that can provide a beautiful, high-maintenance lawn, then colonial bentgrass may be the right choice for you. However, if you’re looking for a grass type that is better suited for golf course putting greens and tees, then creeping bentgrass may be the right choice for you.

Grass Care and Maintenance

Maintaining a healthy lawn requires proper care and maintenance. Here are some tips to help keep your lawn looking its best:

Mowing

Mowing is an essential part of lawn care. It helps to keep your lawn looking neat and tidy. But, remember to mow your lawn at the right height. The mowing height depends on the dominant type of turf grass. For example, the mowing height for colonial bent grass should be 1-1.5 inches, while the mowing height for tall fescue should be 2-3 inches. If you are not sure what type of grass you have, set the mowing height to 2 inches.

Maintenance

Regular maintenance is required to keep your lawn healthy. This includes dethatching, coring, and overseeding. Dethatching is the process of removing the layer of dead grass and debris that accumulates on the surface of your lawn. Coring is the process of removing small plugs of soil from your lawn to allow air, water, and nutrients to penetrate the soil. Overseeding is the process of spreading grass seed over your lawn to fill in bare spots and improve the overall health of your lawn.

Irrigation

Proper irrigation is essential for a healthy lawn. Water your lawn deeply and infrequently to encourage deep root growth. Water your lawn in the early morning or late evening to reduce water loss due to evaporation. Avoid watering your lawn during the hottest part of the day.

Fertilization

Fertilizing your lawn is important to keep it healthy and green. Use a slow-release fertilizer to avoid burning your lawn. Apply fertilizer in the spring and fall when your lawn is actively growing. Be sure to follow the manufacturer’s instructions for application rates.

Cultural Practices

Cultural practices such as proper mowing, watering, fertilizing, and maintenance can help reduce the need for high maintenance and improve the overall health of your lawn. Regularly aerating your lawn can also help improve soil compaction and promote healthy root growth. Finally, be sure to remove any weeds or other unwanted plants from your lawn to prevent them from competing with your grass for nutrients and water.

Understanding Shade Tolerance

When choosing a grass type for your lawn in Oregon, it’s important to consider the amount of shade your lawn receives. Shade can have a significant impact on the health and appearance of your lawn, so it’s important to choose a grass type that can tolerate the amount of shade your lawn receives.

Partial shade, which is defined as an area that receives 4-6 hours of direct sunlight per day, is common in many Oregon yards. If your lawn receives partial shade, you’ll want to choose a grass type with moderate shade tolerance, such as fine fescue. Fine fescue is a cool-season grass that can tolerate partial shade and requires less water than other grass types.

If your lawn receives more than 6 hours of direct sunlight per day, you likely have a high shade tolerance. Grass types that are shade tolerant, such as perennial ryegrass, can thrive in these conditions. Perennial ryegrass is a popular grass type in Oregon due to its quick germination and strong drought tolerance.

It’s important to note that no grass type is completely shade tolerant, and even shade-tolerant grass types will struggle in areas with heavy shade. If your lawn receives more than 80% shade, you may want to consider alternative landscaping options.

In summary, understanding shade tolerance is an important factor in choosing the best grass type for your lawn in Oregon. Consider the amount of shade your lawn receives and choose a grass type with the appropriate level of shade tolerance.

Dealing with Disease and Moss
