Ornamental grasses have become extremely popular in the past ten years or so, and if you get them at a garden centre they are kind of pricey. Learning how to grow them yourself is really very straightforward. They may be grown from seed, but would not pretend to be an expert in that for a number of reasons. One, do not know anything about growing them from seed, and 2, do not have any desire to propagate them from seed since seedlings require too much maintenance. The easiest and most effective way to propagate them is through easy division. Of course you will need at least one parent plant of each variety that you want to grow. If you shop around you could be able to get some 4 inch pots at a reasonable price.
One of every variety is great for a start. Find that the best time of the year to split them is in the spring, just before the new growth emerges. If you buy the stock plants in the spring, you could have the ability to divide them straight away in grass plants. If you get them at any time of the year, just plant them in your backyard or other suitable place, knowing that you are going to dig them up in a month or two, or a year or so.
As the bud literally starves, the yard thins and seems poor. Conversely mowing too high can damage the overall look and usefulness of this turned area. No single bud cutting height is ideal for many turf-grasses; grass cutters have to be set differently for each bud. Within its optimum grass-cutting elevation range, each grass species will be healthier and have a deeper root-system the greater the grass is mowed.
When spring arrives you can split them anytime as long as they are not nicely into putting on new growth. To split them just dig up the root mass and start dividing it into bits. The divisions do not have to be to be very big. It is hard to describe, but so long as you have some roots, the new plant is very likely to grow. In case you have got small young plants you are likely to just tear the main mass besides your hands, but when the root mass is extremely big then you are going to need a few tools.
You might need some heavy duty tools since then have talked with a buddy of mine that works for a large Wholesale grower, and he said that you never want to let a decorative grass Plant get that large if you wish to divide it. He said they plant little Divisions in the area in the spring, and dig them up the next spring and divide them again.
