Ornamental grasses have become extremely popular in the past                 ten years or so, and if you buy them at a garden center they are                 kind of pricey. Learning how to grow them yourself is actually                 quite easy. 
They can be grown from seed, but I won’t pretend                 to be an expert at that for several reasons. One, I don’t know                 anything about growing them from seed, and two, I have no desire                 to propagate them from seed because seedlings require too much                 care. 
The easiest and most effective way to propagate them is                 through simple division. Of course you will need at least one                 parent plant of each variety that you would like to grow. If you                 shop around you might be able to find some 4” inch pots at a                 fair price. 
One of each variety is good for a start. I find that the best                 time of the year to divide them is in the spring, just before                 the new growth emerges. If you buy the stock plants in the early                 spring, you might be able to divide them right away. If you buy                 them at any other time of the year, just plant them in your                 garden or other suitable location, knowing that you are going to                 dig them up in a few months, or a year or so. 
When spring arrives you can divide them at any time as long                 as they are not well into putting on new growth. The earlier the                 better. To divide them simply dig up the root mass and start                 dividing it into pieces. The divisions do not have to be to be                 very large. It’ difficult to describe, but as long as you have                 some roots, the new plant is likely to grow. 
If you have small young plants you can probably just tear the                 root mass apart with your hands, but if the root mass is very                 big then you are going to need some tools. You might need some                 heavy duty tools! 
Last spring I divided several grass plants that had been in                 my landscape for a few years. When I dug out the root mass it                 was much larger and more dense than I expected. Using a very                 good digging spade and some real elbow power I was able to chop                 the root mass into quarters, and I replanted the quarters back                 into my landscape. That still left many clumps that I wanted to                 divide into very small plants that I could pot up in 2 quart                 containers. 
 The root mass was too dense to tear apart with my hands, so I                 literally got a hammer and a 4” wide mason’s chisel and                 chiseled off pieces.  It worked and I now have a couple of                 hundred beautiful little grass plants in 2 quart containers. 
Since then I have talked with a friend of mine who works for                 a large wholesale grower, and he told me that you never want to                 let an ornamental grass plant get that big if you intend to                 divide it. He said they plant small divisions in the field in                 the spring, and dig them up the following spring and divide them                 again. He assured me that if you get them just 12 months later,                 they can be easily torn apart by hand.
