Did you know that there are over a dozen different species of grass that can be used for lawns in Indiana? Chances are you’ve heard of bluegrass, and maybe zoysia grass, but most people don’t have any reason to think about different types of lawn grasses on a daily basis. Lucky for you, we do have reason to think about different types of grass on a regular basis, and today we’ll teach you the basics you need to help pick the right grass for you. There are two main things to think about when selecting a type of grass: warm or cool season and spreading or clumping. Once we touch on those, we’ll talk about some of our favorite grasses for the home lawn.
Cool Season vs. Warm Season Grasses
Cool season grasses do well in areas that get cold in the winter and don’t have extended periods of extreme heat and drought. They do the most growing in spring and fall, and while they get duller in the winter they still have a green tint to them all year long. They are more common in central Indiana and northern Indiana. Warm season grasses thrive in extreme heat, and they can often handle drought better than cool season grasses. Their down side is that they turn totally straw brown in the winter, and they take much longer than cool season grasses to green up in the spring. You’ll find them more often in southern Indiana than central Indiana, and it’s rare for them to be able to even survive in northern Indiana. In the deep south and Florida, that’s about all you’ll see. In the Midwest where access to water for irrigation typically isn’t a problem, the better bet is usually going to be to go with a cool season grass and then irrigate as needed in the summer to help your lawn keep cool with proper moisture levels.
Clump-forming vs. Spreading Grasses
The other big difference between different types of grasses is in how they grow. As you might guess, clump-forming grasses grow in clumps that very slowly expand. They primarily rely on seeding to spread and fill in bare spots. Spreading grasses send out roots and/or stems horizontally to spread much more quickly. Aggressive spreaders can become difficult to contain and can invade planting beds, but strict clump-forming grasses are not able to repair damage easily without help. For most settings, the ideal grass is a moderately aggressive spreading grass, especially for areas that expect high foot traffic from people or pets.
Some of Our Favorites
Our favorite grass for lawns, bar none, is rhizomatous tall fescue (a.k.a. RTF). RTF is a spreading, cool-season grass, but its benefits go far beyond that. It is drought-tolerant, disease-resistant, and pest-resistant, and it doesn’t require much fertilizer to form a lush, green lawn. In fact, pest or disease problems are usually an indicator of over-fertilization. It stands up to high heat much better than most cool season grasses. It has a deep green color and medium texture for a comfortable walking surface. It has a fairly quick germination time, so you don’t have to wait weeks for seeds to sprout. It even does well in shade! It’s not the most shade-tolerant grass available, but it’s one of the best for a lawn with mixed sun conditions. Is there anything it can’t do? Not really. It doesn’t do well in dense shade, especially wet shade, but in those conditions there’s no lawn that will thrive and also be able to survive our cold winter.
RTF is a relative newcomer on the turf grass scene, and before its arrival on the market in the early 2000s, bluegrass was the best selection for an attractive, walkable lawn. A well-maintained bluegrass lawn is truly gorgeous. But it falls behind RTF in several areas. It requires much more fertilizer and water, it is fairly susceptible to disease and pest problems, it doesn’t hold up to extreme heat as well, it isn’t as shade-tolerant, and it takes up to a week longer for seeds to germinate. But bluegrass remains a popular choice for its nostalgic appeal and because there are so many high quality bluegrass lawns around already. It can make more sense to repair an existing high quality bluegrass lawn with the same species for localized damage than to totally convert them to a new species.
Another grass we occasionally use is buffalo grass. It’s one of the only turf grasses native to North America. It grows naturally in dry, tough settings from North Dakota to Texas, so you know it can take some abuse. It also needs almost no mowing. Buffalo grass rarely gets above 3” tall, so it only needs to bed trimmed to encourage thicker growth, and it needs to be edged to keep out of areas where it doesn’t belong. It’s tough as nails, but it’s not conventionally attractive. It will never get a lush, vibrant green, and the more you try to fertilize it the worse it will look. We recommend it for areas where you want a lawn, but you don’t want to have to maintain it, and you’re not expecting a golf course look. We have also used it in settings where clients want to use only plants native to North America.
For really shady areas, we recommend going for mulch or gravel beds or a shade-tolerant groundcover instead (Stepables has some for high foot traffic), but if you really want lawn, and RTF can’t handle the shade, you have a few other options. Most hardware stores and garden centers will carry shade-friendly seed mixes that are typically a mix of fine and creeping fescues. Zoysia grass is a warm-season grass with pretty good shade tolerance, but since it is a warm season grass it will look dead for up to six months out of the year.
