Help! Soil we brought is was FULL of weeds
Comments (19)Thanks jonas302. I'm in SW Indiana. I'm going to look up info on Rye. I don't know a lot about it, but that seems like a good place to start my next learning! I've decided not to use any chemicals anywhere outback. I use only natural stuff even for cleaning out my pets and livestocks places. I've got too many kids and animals that run loose and only two eyes. The animals will drink out of any water source they find and the kids are always playing in any water that's around. Since I'm not a chemist, I've just stayed away from all chemicals, pesticides even store bought fertilizers. That way they aren't around for the kids to get into the containers, and I don't have to panic that the rain water could pick-up any chemicals from our ground and hurt anyone or animal that ingests it or gets it on their skin....See MoreWeeds in TopSoil and I haven't even planted flowers yet!

Comments (4)For future reference, putting soil on top of a smother defeats the purpose. Also, the newspaper or cardboard needs to remain undisturbed until anything under it is dead. Otherwise, the unwanted plants will come up through the holes you made to add new plants. Many seeds are blown around in the air, and critters move them around in various ways. There will always be unwanted sprouts in any garden situation....See MoreWeed control in top soil
Comments (3)Preen is a bad idea. Preen is a particularly bad idea if the end goal is a no mow native Rocky mountain meadow of sorts. There are numerous ways you could reach your end goal. However, this is no different in many respects from establishing a more conventional landscape. There is no magic dirt, seed mix or chemical that you can spread and forget. It will take some weeding, maintenance, time and thought to reach your goal....See MoreStarting a new lawn in weed ridden clay soil
Comments (11)Have to agree with gardengal, at least for me. If you were in Darwin I'd have a shot at the warm season grasses. But you need a cool season grass person who knows the names of grasses in your Ozzie speak. If you were in the US I'd say you could use a mix of fescue (Festuca arundinacea), rye (Lolium family), and Kentucky bluegrass (Poa pratensis). I'm fairly certain you have the same species available, but with different common names. You are coming into spring to do your seeding. For us in most of the US, that's a poor time to seed for two reasons. 1 is the heat, but looking at your climate, yours seems to be more like our Pacific Northwest (gardengal's home turf, so to speak). In other words, heat should not be a problem for you in the summer. The second reason is the summer weeds like to sprout in the spring. Again, not knowing what your summer weeds are, I can't comment beyond that. Our main summer weed problem is crabgrass (in the Digitaria family of grasses). I believe crabgrass to be a worldwide plant used as forage for livestock. If you folks have it, I'm so sorry. I would expect it in Darwin because it is a HOT season grass, well adapted to tropical climates. Sounds like you are starting fresh. With that in mind, here are my suggestions. These match with morpheuspa after my pre-preparations. Water the weeds lightly (5-10 minutes), 3x per day, every day for a week. The idea is to sprout as many weed seeds as possible. After a week spray everything with Round Up (glyphosate). Continue watering as before to sprout any weeds that take 2 weeks to germinate. Spray with RU again. The whole idea here is to sprout all the weeds before you put your favorite seed down. If you don't do these steps, those seeds will sprout along with your expensive grass seed. Crabgrass, for example, sprouts first in just a few days, which makes it look like you're a seeding genius, when in fact, your lawn will be all crabgrass by mid summer. Rake up all the dead stuff. Evaluate what you have left as far as soil profile. If you have high spots, scrape those off with a hoe and fill the low spots. If you still have low spots, fill those with topsoil and crush any clods into dust. Water the topsoil to settle it and look for new or remaining low spots to fill. Fill any new or remaining low spots and water again. Repeat step 8 until you are entirely happy. What you are doing is setting up the turf profile. You can make it as smooth as a putting green, and the smoother you make it, the (much) happier you'll be later on. There is nothing less fun than mowing a bumpy lawn...for years and years. Now you are ready for morpheus' step 2. I'm with him on the install. I'm just a little more persnickety on the soil prep. As morph mentioned, don't think of dense clay as a handicap. It could very well be you have no clay at all. Don't be shocked. In the US about 90% of people fretting over clay soil have no clay once they get a good soil test done. Are there any brick making factories near you? If not then you might have a salt imbalance instead of clay. Morph suggest a soil test from Logan Labs in Ohio. I'm relatively certain they test soils from around the world. I know the big private test lab in Texas does. The cost will be $20 US plus postage. The benefit is that morph is extremely familiar with their tests and will give you about $200 of free advice if you post the results here. They email the results, so it's pretty fast. The other benefit of the LL test is they do a lot more tests than a typical university test lab for the low low price of $20. You could get all the LL tests from a university, but the cost would be a lot more than $20. Their test will tell whether you have clay or a salt imbalance. It will provide organic content (I'm guessing yours is around zero if it's cracked open) and soil pH. They also provide micronutrient balances. It's a great test. Wherever you get your test, do not use gypsum or any calcium until you have a test that tells you what kind of calcium and how much. The LL test will tell you - or morph will tell you based on his reading from the results. He'll tell you what products to use, when, how much, how often, and he usually explains why or why not along the way. You also need to decide if you are going to water with a hose and surface sprinkler or install a buried sprinkler system. NOW is the time to install if you're going that route. Now that I've written all this stuff, I reread your initial post. New house build. Did you have a landscaper do final grading around the house??? This is critical as I've spent a lot of time under the assumption that your yard is already profiled for drainage. If it is not and still looks like a construction site, then you need a landscaper to bring in, or remove, enough topsoil to give you a soil profile that drains water away from all the buildings and away from any neighbors. Can you post a picture or two taken from the street or from 20 meters away from the house. Here is a picture of a landscaper doing final grading in a level neighborhood. Also it doesn't hurt to give us the name of your town/city/village. If your landscaper is going to bring in new soil, don't get the soil test until after he's finished. He does not need to amend it going in. Unless it is really junk soil, it can be fixed with surface applications and by growing stuff in it. Weeds might be ugly, but they do provide roots in the soil which are organic....See Morereeljake
