three days, you can grow it on cement practically, it is usually used in winter, but I have used it in hot summer weather with watering, kept it mowed and have at least a green lawn short term. The green blades and the roots are super easy to rototill in for the real grass later and it adds organic matter (green Manure) to the soil. Even if you rototill and don't amend or even cover with mulch, seeds of annual rye sprouts faster than most weeds and smothers them pretty well, especially if you mow the grass high, and that shades out many of the weed seedlings. Annual rye is super cheap too (Lolium multiflorum) not perennial rye (Lolium perenne) and the grass clippings make great mulch too, or added to brown compostables does a quick compost combo. It also helps get the seed for the permanant lawn to sprout faster and is termed a "nurse crop" for that purpose. I have put it on weed infested areas, not rototilled the dirt, in hot weather, watered it and had green mowable lawns in less than two weeks, that lasted for a several weeks, cost was about $10.00 for the big bag of seed.

on the cardboard, and after three weeks everything under should be so starved for the sun it will be dead, if not do it for another week. (Other things work too, cardboard is just easiest)

Bayer 3 in 1 has the fungicide too. I think you have to keep using it for it to work correctly and eradicate the fungus. To help keep new fungus from spreading before the Bayer kicks in, a couple things can be used on the leaves that are organic and won't hurt even with the Bayer. If you have powdery Mildew, spray the leaves with milk, it really does work! Do it once or twice a week If it has Rust, a spray of Baking Soda and water-1 1/2 teaspoons per quart of water- also once a week, can prevent it from getting out of control. Leaf Spot or Black Spot are able to be kept controllable with 1/4 teaspoon of white or cider vinegar in a quart of water. Once a week. Spray when the temperatures are below 85 and in the morning or evening not in the middle of the day when it is hottest. Do not spray all of these at once either! Maybe a day or so apart if you have all three diseases. Then there are products from organic companies that also really work, Planet Natural; Gardens Alive; and there is something called Actinovate is a new organic fungicide I have found online, and at one of my local Garden Centers, which works too. Don't use other products that are chemical fungicides, until you wait for the time limit on what the label on the Bayer recommends. Only use the organic ones listed above. I take care of a few hundred roses in several gardens a week, using only these organic measures, but I also use other plant health building practices which help them stay disease free. And They are very very healthy, no diseases, no chemicals.

on the squash plant is not being pollinated. It looks very very similar to blossom end rot, a calcium deficiency, but no amount of calcium fertilizer will do anything to fertilize a flower, which is easy to do yourself. This has the information you need that explains how to handle this problem. It also usually an issue early in the season, and for the first several baby squash. http://blog.mountain-plover.com/2009/08/03/h.... Adding calcium to vegetable gardens actually is a good plan before planting, tomatoes especially get blossom end rot, and calcium is the only thing that will correct that.

""The Blooming Gardener is "Wrong" about these. I have them all over my yards, front, back and side yards too. They are Amaryillis, RED SPIDER. Contact RAREBULBS on Ebay and he might have his own web site by now and you'll know that I'm right.""

I would also never post that someone is "Wrong" followed by 'and that you'll know I'm right' even if later admitting you stand corrected. It wasn't a contest for who is more right, but to help ID what is this plant :(

okay in your situation. Carpet works too, and other things block the sun...depends on how ugly you can tolerate. Carpet stores usually have sections of removed carpet in their dumpsters from their jobs.

Bloom for some of my clients. They love the shade for their roots and grow out to the sun to be covered in blooms. Makes the Decidous Magnolias able to be focal points during the warmer months!!
