Now onto the latest issue. Our landlord fixed some grading in the back of the house and moved a large area of 70's landscaping rock to a new area. He asked that we seed or plant flowers or something where the rock was removed (there's still quite a bit of small rock in the soil and our soil is incredibly sandy). We raked, spread seed and then watered and the grass started growing, but all the seed fell into little lines where the rake tines were. Where the soil hills were is now hundreds of little weeds! I've attached a picture where you can see all the weeds. After reading on the Minnesota extension site I now know that this is the WORST time to till the dirt due to weed germination. What should we do? I'm thinking to just scrap the area and cover it with plastic or something? Or will the baby grass be able to overcome the weeds? We also have a large patch that we painstakingly weeded where an above ground pool was and had put down seed too, but that seed never sprouted. Should we cover that area until later in the year?

Sorry this is so long but we are such newbies and since we are renting we want to do this right and not ruin the yard.

Start now to get into good lawn habits. Here they are...

Basics of Lawn Care

After reading numerous books and magazines on lawn care, caring for lawns at seven houses in my life, and reading numerous forums where real people write in to discuss their successes and failures, I have decided to side with the real people and dispense with the book and magazine authors. I don't know what star their planet rotates around but it's not mine. With that in mind, here is the collected wisdom of the Internet savvy homeowners and lawn care professionals summarized in a few words. If you follow the advice here you will have conquered at least 50% of all lawn problems. Once you have these three elements mastered, then you can worry about weeds (if you have any), dog spots, and striping your lawn. But if you are not doing these three things, they will be the first three things suggested for you to correct.

Watering
Water deeply and infrequently. Deeply means at least an inch in every zone, all at once. Infrequently means monthly during the cool months and no more than weekly during the hottest part of summer. Do not spread this out and water for 10 minutes every day. If your grass looks dry before the month/week is up, water longer next time. If that does not work, then you might have to water more than once per week during the summer's hottest period. Deep watering grows deep, drought resistant roots. Infrequent watering allows the top layer of soil to dry completely which kills off many shallow rooted weeds.

You will have to learn to judge when to water your own lawn. If you live in Las Vegas your watering will be different than if you live in Vermont. Adjust your watering to your type of grass, humidity, wind, and soil type. It is worth noting that this technique is used successfully by professionals in Phoenix, so...just sayin.' The other factors make a difference. If you normally water 1 inch per week and you get 1/2 inch of rain, then adjust and water only 1/2 inch that week.

Mowing
Every week mulch mow at the highest setting on your mower. Most grasses are the most dense when mowed tall. However, bermuda, centipede, and bent grasses will become the most dense when they are mowed at the lowest setting on your mower. In fact there are special mowers that can mow these grasses down to 1/16 inch. Dense grass shades out weeds, keeps the soil cooler, and uses less water than thin grass. Tall grass can feed the deep roots you developed in #1 above. Tall grass does not grow faster than short grass nor does it look shaggy sooner. Once all your grass is at the same height, tall grass just looks plush.

Fertilizing
Fertilize regularly. I fertilize 5 times per year using organic fertilizer. Which fertilizer you use is much less important than numbers 1 and 2 above. Follow the directions on the bag and do not overdo it. Too little is better than too much. At this point you do not have to worry about weed and feed products - remember at this point you are just trying to grow grass, not perfect it. Besides once you are doing these three things correctly, your weed problems should go away without herbicide.

Seed in the early fall.

Is shade an issue? If not then Kentucky bluegrass is the type of grass that will spread to fill in holes and thin spots. But it does not grow in shade. In shade you'll need fescue. Hence the sun/shade seed mix. Fescue does not spread like KBG. If you can get a seed with no rye in it, I would take that over one with rye. Rye can be beautiful but for beginners it can trick you into making a mistake at the outset. Rye does not spread either. For a rental you can get your seed at any box store. Seed from there comes with weeds but who cares? You'll get your deposit back anyway even with a few weeds.
