Tall grass, specifically tall fescue, does have the ability to spread, but it does so in a different way compared to other types of grasses. Unlike grasses that spread by horizontal above- and below-ground stems, tall fescue is a bunch-type grass. This means that it grows in clumps or bunches rather than spreading out horizontally.
Tall fescue primarily spreads through vertical shoots called “tillers.” These tillers grow from the base of the grass plant itself. As the grass plant matures, these tillers emerge and grow upwards, adding to the density of the clump. Over time, these tillers can cause the clump to expand and become larger.
While tall fescue does have the ability to spread through tillers, it is not as aggressive in its spreading as some other grasses. This can be both an advantage and a disadvantage, depending on the specific situation.
One advantage of tall fescue’s spreading behavior is that it tends to maintain a more compact and contained growth habit. This can be beneficial in certain landscaping scenarios where a more controlled and neat appearance is desired. The clumping growth habit of tall fescue can create a visually appealing texture and structure in a lawn or garden.
On the other hand, the slower spreading nature of tall fescue can be a disadvantage if you are looking for a grass that will quickly fill in bare or patchy areas. In such cases, other grasses that spread more aggressively through above-ground stolons or below-ground rhizomes may be more suitable.
In my personal experience, I have found that tall fescue can be a great choice for lawns or areas where a more defined and contained growth is desired. It can provide a lush and attractive appearance without the need for constant maintenance to control spreading.
To summarize, tall fescue is a bunch-type grass that spreads primarily through vertical shoots called tillers. While it does have the ability to spread and fill in over time, it is not as aggressive in its spreading as other grasses that use horizontal above- and below-ground stems. This growth habit can be advantageous in creating a more compact and controlled appearance in a lawn or garden, but it may not be ideal for quickly filling in bare or patchy areas.
