If you are curious as to what else these grasses have in store. We’d be glad to tell you there are plenty of interesting things. Let’s dig in and find out.

Bermuda Grass vs Kentucky Bluegrass – Appearance

Bermuda grass (cynodon dactylon) is one of the most popular warm-season grasses, and it has a very attractive appearance. Bermdua’s blades have a dark blue-green color that mainly glows in the warmth. Upon looking at bermuda, you’ll also notice that even though its grass blades are soft and plump, the grass is typically coarse-textured. Blades will have small hairs on the sheath, and their usual height will range from 4 to 16 inches. When it comes to identifying a Bermuda grass lawn, you’ll be able to recognize it by its dense growth. This grass is known to spread aggressively by stolons and rhizomes, and some of above ground stems will be visible.

Furthermore, Kentucky bluegrass is a cool-season grass with a dark green color. Despite what its name suggests, this grass is not blue but has some other interesting features. This grass will have canoe-shaped leaf tips, and a visible vein will run through the middle. You can also say that its leaf tip resembles that of a boat, and its seed heads resemble a tree. Kentucky bluegrass is one of the softest grass varieties and has a fine texture. Its rounded edges keep the grass soft even after mowing

Bermuda Grass vs Kentucky Bluegrass – Growth Requirements

Each grass has a specific set of needs essential for healthy growth. Regarding bermuda and Kentucky bluegrass, their needs are somewhat similar but distinct nonetheless.

Bermuda grass 

Since bermuda is a warm-season grass, its first and most important growth requirement is high temperature, full sun, and direct sunlight. It may seem exaggerated, but your bermuda will die if it doesn’t receive at least 6 hours of sunlight daily. Refrain from planting this grass in a partially shaded area, and remove any furniture, trees, or shrubs blocking the direct light. As you know, Bermuda’s peak growing season starts in late spring and lasts throughout summer.

It goes into dormancy during the winter months to preserve its energy and comes out in early spring. Some maintenance necessities must be fulfilled during that period, but we will get to that later. As for its soil medium, the good news is that bermuda is adaptable to various conditions and can grow in almost any type of soil. It’s the most preferred medium, well-drained sandy soil, but you can grow it in clay, loamy, and silt. However, make sure that the ph level ranges from acidic to neutral (6-7) 

Kentucky bluegrass

On the other hand, Kentucky bluegrass is a perennial cool-season grass that comes year after year to thrive on your lawn. Its optimum growth period is in the spring and fall season but it goes dormant if the temperature drops too low. A Kentucky bluegrass lawn needs at least 4 hours of direct sunlight to grow properly, and unlike bermuda, this species can tolerate partial shade. However, if it’s left in the shade for too long and necessary sunlight isn’t received, it will gradually thin out and die. 

Even though Kentucky bluegrass is a cool-season grass variety, it will be severely damaged under prolonged periods of freezing temperatures. As for soil type, it is also adaptable to various soil conditions as long as they are well-drained and have a pH between 6 and 7. Kentucky can tolerate wetter soil than bermuda but doesn’t necessarily prefer sandy soils.

Bermuda Grass vs Kentucky Bluegrass – Characteristics 

Another thing that’ll help you choose between Bermuda grass and Kentucky bluegrass is comparing their characteristics. Look at their distinct features listed below and decide which seems more appealing.

Bermuda grass 

Bermuda grass is an invasive and fast-growing grass that, despite its advantages, can come across as aggressive. It is a warm-season grass, so its main characteristic is its ability to grow in warm weather and hot temperatures. The ideal temperature ranges between 95 and 100 degrees Fahrenheit, meaning that bermuda can stand in scorching heat for hours without getting affected. Bermuda’s grass seeds start germinating in early spring and fully green up by the end of the season.

It is no surprise that this tough grass is drought tolerant as well. This means that your bermuda will be able to survive and grow in the harshest of weather conditions. Bermuda’s drought tolerance enables it to survive hot and dry conditions, but it is not the same as drought resistance. Bermuda will keep growing but turn brown when an adequate water supply isn’t given.

You need to know that even though Bermuda’s growth won’t be as effective in drought conditions, it will happen nonetheless. If you’re living in an area that continuously undergoes drought and lacks water, then bermuda will be the best choice for your lawn. Normally, your grass needs an inch of water weekly for optimum growth, but you can reduce it to a quarter of an inch in the drought season. 

One of bermuda grass’s most beneficial characteristics is that it can repair itself quickly. As you must know, this grass performs peerlessly under heavy foot traffic and establishes a thick turf. If it gets damaged or trampled because of frequent use, it will bounce back on its own with minimum effort from your side. Recovery will be even faster if your grass blades are well-mowed and properly fertilized with nutrients.

Kentucky bluegrass

Kentucky bluegrass is one of the most popular cool-season grasses and the softest among all varieties. This grass is mostly used in northern states and northern coastal areas or transition zones, where their qualities will be useful for lawn owners. Even though Kentucky is more shade-tolerant than bermuda, that doesn’t mean it’s very good at it. If this grass is planted in an area where direct sunlight isn’t accessible, it will start losing its dark green color, and its quality will decrease. To state it as simply as possible, this grass should be planted where 3-4 hours of direct sunlight and 4-5 hours of indirect light are easily available. 

Kentucky bluegrass grows and spreads quickly, but unlike bermuda, it doesn’t have a deep root system. It reproduces through underground stems (rhizomes) and covers your lawn with its soft texture. This grass is pleasant to walk on barefoot and a great option for yards, golf courses, and school playgrounds. It can also tolerate high traffic and perform well under frequent use, so your kids or pets can play on it for hours.

Like Bermuda grass, Kentucky bluegrass also has an excellent capacity for self-repair and can bounce back quickly after damage.

Bermuda is a type of grass that is high maintenance and grows best with your undivided attention. The same can be said for Kentucky bluegrass because they have specific needs.

I.e when the grass reaches a certain height, get your mower ready and give your lawn a trim.

Lastly, Bermuda grass should be fertilized with 4-5 pounds of nitrogen-rich fertilizer per 1000 square feet. The best time to apply fertilizer on a bermuda lawn is between March and August. On the other hand, Kentucky bluegrass needs proper fertilization in autumn and occasional application of diluted fertilizer for the rest of the year. Fertilizers are essential because they will speed up the seed’s germination process and ensure a green lawn all year.

Occasional aeration might also be needed based on your lawn’s condition. If your soil is compacted, you should use core aeration to punch holes in the soil surface to encourage better circulation. Lastly, If there is a noticeable thatch build-up on the top layer of soil, you should use the proper tools to repair the situation.
