Try bird feeding departments or stores. I use the tree hooks (really big s-hooks), one close to the trunk and another as far out as can bear the weight (or on two different limbs) with a chain connecting them. I hang the plants from the chain.

You have asked a very difficult question to answer, at least from my experiences and practices. But try to give an answer I will ...... If your grasses are exceeding the advertised height then some might say you are very lucky?!!! Generally exceptional growth is due to ultimate growing conditions. Soil, moisture, light, mild off season or winter. These are some of the main ingredients or pieces of the pie that really controls the growth of any plant. Now to address your question. By confining your grass to a smaller container may possibly stunt the grass growth but more likely it will hamper the fullness of the grass and cause the fronds and plumes to be sparse and basically unattractive. Cutting the bottom out of the pot really does nothing as the roots will go deeper to get more open space to grow thus allowing the grass to maintain it more natural growth in the location where you have it now growing. Cutting out the bottom is a method that some growers will use to stop the spread of a plant whether it is a grass or perennial "flower". Controlling the spreading habit in this scenario has proven to be worthless in many cases as the roots will go deeper and come up on the other side of the pot. Last but not the least would be to cut the top of the grass back at the desired "advertised" height making the grass appear as being butchered. Ain't nothing pretty or attractive about this scenario. In closing I would suggest you read a couple of ornamental grass books and find a grass or grasses that would fit in your garden area or at least in your minds eye. What better excuse to have more grasses in your landscape and garden areas? Jake

On the subject of little bluestem. Here in the city, the Historical Museum planted, on large hills with big rocks, a lot of some variety of it. Some get quite a bit of afternoon shade and others are in more sun but all seem to do quite well visually standing straight and tall. The thing is, I have no idea what variety this is. Its is very tall, extremely vertical with straight dense leaves that are a striking solid dark metallic blue without a hint of red or purple. Taller than any I have seen anywhere and they don't look anything like what I see growing wild. Then the seed heads are at least up to your thighs in the fall. I am going to collect seeds this fall. Also, there are volunteers coming up in the grass and I have it in mind to go out and collect a few. (can you do that?) They just get mowed anyway. I guess I should try to get permission to "weed" the lawn. Got any ideas what kind this might be?

The grass clippings themselves are fine for the potted plants. What would be an issue is any weed seeds blown into the pots as well. The clippings will eventually and slowly break down, but not nearly like they would in a compost bin/pile. Adding a few worms to each pot could accelerate the breaking down of the grass. Another issue that might be of concern to some is that if the grass is sprayed with herbicides or fertilizers. Those would end up in the soil of your pots as well, something especially concerning if you are growing edibles. I have mulched a few pots in the past with grass and aside from having to pick through a batch of sprouting weeds, I have yet to run into any real problems.
