I have grown grass in a pot, and now it is about 3 inches tall. But I have noticed some kind of white fluffy stuff on the surface. What is it? Is it poisonous to plants?
This is generally a fungus mold and may be due to soil that is not sterilized.
Make sure you use a good quality potting soil for container plantings.
You also can have fungus and mold issues if the plant does not receive good air circulation and or too much moisture.
Most types of fungus like this will not kill the plant, but you can make sure it does not spread or continue.
Increase the light and even place a small fan in the area.
I have a silver maple tree in my backyard that is very old and its roots show over the dirt. The roots that show over the dirt seem to be growing laterally and are about ten feet long. It seems to me that the tree took over my backyard and that is why my grass stopped growing. My backyard looks terrible to me with out grass, so I am wondering what I can do to grow healthy grass between the maple's roots. Thanks!
You may want to consider a ground cover that may do better then grass under a large shade tree.
I live in Iowa...summers are hot and dry, I have next to no shade...what is the best kind of grass to plant. It's new construction so there are alot of weed to get rid of.
Personally I would say Kentucky Bluegrass, or any fine Fescue. These would be suited just fine for your area.h
Is it possible to grow smooth cordgrass in a box (outdoors) and if so, how? We we would like to do it for a movable demonstration project about wetlands that goes on a truckbed. Thanks.
This can be done, as long as you can replicate its native environment. This article will help you on their care: https://www.gardeningknowhow.com/ornamental/water-plants/cordgrass/cordgrass-plant-growing.htm

How soon after fertilizing can I put down grass seed?
I would allow at least a week to let it break down a bit. I would recommend fertilizing after the grass has established. Too rich of a soil at germination can burn young seedlings.
Comment first: I am a board member of Cranberry Creek HOA in Little Egg Harbor,southern Ocean County, New Jersey. Our soil is a compacted sand and gravel, with some clay. Grass does not grow without a lot of attention, water and fertilizer. What grass we have is leftover from sod put down by the builder 10 years ago. We have about (estimate!) 60,000-70,000 sq ft of open sandy soil, about 1/4 irrigated, all in strips 10-20 ft wide. What can be grown that looks green?

Have a few grass plants want to save this winter. Would like to save if I can
You can wait until the potted grass is dormant and then store in a garage or cool location.
