Also for watering: the soil looks too dry too soon currently. Mine, too--and I have no real problems. The very top surface of the soil dries out really fast in sun and wind, but that doesn't mean there isn't water underneath. You can test that by pushing a screwdriver into the soil. If it goes in fairly easily (barring rocks), your soil is damp. Or drive a small trowel into it and separate it into a V shape by rocking it a little bit. That'll give you a direct visual on how deep the water is. Here would be my plan: for now do very frequent waterings to help really wet the soil, I'm not familiar with California (except for the part about moderate temperatures and no rain), but this doesn't sound like a good idea--it encourages shallow roots and lawn diseases. The standard is 1" of water a week, all at once (well, within a day to allow for on/off cycles to allow the water to penetrate). For sandy soil your mileage will differ because the water wicks out fast and goes very deep very quickly. I will also probably try milorganite as a jump start, as I fear my soil is probably pretty depleted. I swear by it, others don't (it is processed sewage, but heated enough to kill everything in it). The 18 lbs/thousand square feet I put down last weekend kicked in and it's a rainy week. The grass, since Sunday, has grown one and a half inches and gone a deeper green. Once it stops raining, I'll mow. I went high, but I'm going to renovate this fall--with a deep, heavy core aeration I want lots of organics mixing into the holes. I alternate it with alfalfa and soy. When I started (early last year), my soil profile was slightly silty clay, poor drainage, very poor water penetration, hard as a rock, and a light tan. It had been corn field for as long as I could remember prior to building, and even my parents don't remember when it wasn't. Call it 40 years of abuse. Now it's still slightly silty clay (nothing's going to change that short of a renovation down to a foot or more). Drainage is fair to good, penetration is good to excellent, the soil is still hard when dry (it's supposed to be), but spongy when wet. The top half-inch is black, another inch is deep brown, and a good three inches below that have turned a midrange brown. Everything grows better and more strongly. I'm very pleased. Some older photos are here. I have to update them--the grass has improved since these were taken and the season advanced a bit.

1. It's too dry here to core aerate and though that is not needed once on an organic plan, right now I think it's needed as a jump start. Do I have any other options? Use a soaker hose set on a trickle at the faucet. Leave it on day and night for a full week and then move it about 18 inches away from that spot. I start at the highest part of my yard and work downhill. After you have finished the entire yard, repeat the entire process two more times. That should soften your soil. This works by providing a good environment in the soil for beneficial fungi to grow. 2. My lawn has had some white/yellow patches the past two years, i previously treated with a fungicide, what options do I have organically? Apply ordinary corn meal at a rate of 20 pounds per 1,000 square feet. If you are worried about disease, repeat every two months. You might look for a Weed Hound tool at your local box and garden stores. It's about $20 and worth about $40.

It's not monthly but I recently started this organic lawn care program. They have a 4 step and a 6 step. I just put down my first treatment yesterday which is a soil conditioner. It seems to be a fairly new company but I've been messaging another member I've found that uses them and so far we're both happy. The contact we've both had with them was very possible and they were able to help diagnose some of my problems. It's a mail order program. They ship you the stuff when it's time to apply. I like that because I never seem to remember to do anything in the spring. Feed stores and the organic products aren't easy to find around me without dealing with traffic, tolls and long drives. The other person I've been talking with seems to like it because they have a large lawn and have a lot of material delivered to their door rather than having to load and load. A good portion of the nitrogen your lawn needs can be gained by leaving your clippings on the lawn and mulch mow the fall leaves. If your son has issues with pesticides and herbicides you need to be able to accept that you might have some weeds and bugs in your lawn. If you build a good healthy turf with good mowing and watering practices, augmented with a good organic feeding, you can help keep them to a minimum. Hand pulling will also help. Milky spore disease and/or nematodes could help you keep your grubs down to a population that shouldn't cause damage to your lawn. I used to do about everything wrong you could do to a lawn. Let the grass grow to much between mowings, mainly let mother nature water, never really fertilize, bag my clippings and fall leaves, etc. Last year I started mowing more frequently and watering on a good infrequent basis and I saw very good results. The color was still poor, I had some thin spots and a lot of weeds still. I'm hoping the mulch mowing and the organic program will help me get it a little denser and a bit darker in color. I limed the lawn to try and get the pH right and will be aerating and overseeding with some better seeds in the fall as well. A lot of people in my area don't do anything but mow once a week and they have nice lawns. Not great, a bunch of clover (which adds nitrogen) and other weeds but it's not so bad. I had my doubts about organic programs until I saw some of the photos from other members on this and other forums.

SC77 said the stuff in italics... Core aeration is not just about compaction. It's about getting oxygen to the roots, plus a priceless opportunity to get compost 3-4 inches down into your soil. It takes a lot more time to get OM down to the root level simply by topdressing a lawn, plus you run the risk of losing precious OM through runoff. Core aeration is a poor substitute for having proper fungal mass and thousands of miles of fungal hyphae enmeshed throughout the soil. There's no way you can achieve thousands of miles of core removal from a typical lawn, but a good fungal colony can do that in a week. OM doesn't run off. OM is sugars, living roots and microbes, and dead roots and microbes. They don't flow away, they live there or are stuck there. Sugars don't flow away because, as Dr Ingham said, they are only released from the plant roots in dosages needed to control the soil microbes. Compost - I have to challenge you on the importance of compost as well. I don't think it can simply be replaced by using organic fertilizer. The two play very specific and separate roles in organic lawn care. Maybe, in a very well established, mature organic lawn, one could get away with simply adding fertlizer such as alfalfa, sbm, or cgm, but in those of us that are still building up our OM %, compost is priceless. "The soil must first be alive in order for fertilizers to function well" -Paul Tukey (The Organic Lawn Care Manual). I agree there are two different functions for compost and organic fertilizer. Compost supplies microbes. Organic fertilizer provides protein...and lesser foodstuffs. What we might disagree on beyond that is how long it takes for organic fertilizer to build the population of microbes that were thought to be missing. If the microbe population is teensy, it might take longer for the fertilizer to work. But if I can apply 10 apps of fertilizer for the cost of compost, that's what I'll do. Fertilizer seems to work in 3 weeks. The use of compost is fraught with peril in that even a normal application of 1/4 inch can set a lawn back for a full season. Why? Because getting an even 1/4-inch seems to be impossible. Some places will have none and some will have 3/4 inch. Where there is 3/4 inches, the grass likely will die from being smothered. Sure it can be done, but we try to deal in practicalities. Every single year for the past 20 I have seen lawns killed or nearly killed by compost. I've never seen any lawn even slightly tainted by using too much organic fertilizer. ...price [of compost] doesn't have to be a problem. I further agree that price does not have to be a problem. My property in San Antonio is completely covered with trees and that is not enough to make a decent compost pile. I collect leaves set out by the curb to make a pile. With 20 large bags of leaves I make enough compost to treat our garden beds, about 1,000 square feet. I have seen you question Tukey's advice, but he is far from the only one suggesting that the addition of compost be at the core of every organic lawn program. Compost improves soil structure, adds microorganisms, balances pH, feeds existing soil life, and adds around 1% nitrogen, phosphorus, and potassium. 5% is the optimal amount of OM, which takes a long time to achieve anything beyond that is just gravy and won't hurt the lawn, only improve it. Tukey is an organic gardener in the tradition of Rodale. Without rereading anything of his, I would suggest that if he is a disciple of Dr Ingham, it is only inasmuch as she is a proponent of compost and not to the extension of the value of microbes feeding directly on protein dropped on top of the soil. If you want to rapidly improve the OM in your soil, you need to talk to morpheusPA. He has a few recent posts on this forum, but he has thousands of posts on another forum, and more recently has branched off into his own blog. He boosted the OM on his lot by several percent in one season by using zero pounds of compost but thousands of pounds of organic fertilizer. That was the nutritional equivalent of 2 cubic yards of compost applied every weekend all season long. There is no way to do that with compost in a practical or economic manner. It was more of an experiment, but it really, REALLY worked! So the idea that is takes a long time to improve the OM percentage is simply false. If you use the wrong materials, like compost, then yes, it takes a long time. Something you missed in the interview with Dr Ingham was the references to feeding the compost before using it. She didn't mention what she feeds it with, but I have talked to another of her disciples who uses a dose of oatmeal to feed her compost prior to converting it into compost tea. In other words, she recommends feeding it a protein filled organic fertilizer. Well, if you're going to feed the compost before applying it, then why not just feed the soil directly? After seeing this post I am further confused. You said you learned what you know from Dr. Ingham, but she is a HUGE proponent of the benefits of compost and compost tea. Tukey and Todd Harrington are both disciples of Dr. Ingham and they all agree on the importance of Compost and Core Aeration. Harrington has the largest residential and commercial base of organic lawns at over 2000 and is considered to be the forerunner in the industry. Dr Ingham is absolutely the premier leader in the compost tea movement. Great compost tea is a function of starting with great compost and following a critical set of rules for making the tea. One of those rules which is rarely mentioned is the water temperature. The problem cropped up with a critic of hers in Phoenix who ended up making worthless tea in the Arizona heat. Ingham called it, essentially, a rookie mistake by the Phoenix researcher. Aerobic microbes cannot live without air and water above 80 degrees F barely holds enough air for normal aerobic life. Trying to make compost tea above 80 degrees is a fool's errand because you have a concentrated population of microbes along with plenty of food. Once the air is depleted (immediately!), the aerobic microbes die and the tea is taken over by anaerobic microbes. But Dr Ingham does not mention this fact in the general guidance about making tea. Essentially this factoid limits the making of compost tea to a "non-summer" activity. You really want water between 50 degrees and 70 degrees for best tea performance. So I wish she was more up front about that aspect of tea making. I have seen so-called professional tea makers running their equipment all summer long and selling compost tea which is microbially worthless. Harrington is selling products and services. The profitability of aeration and the application of compost is through the roof. He'd be an idiot if he didn't promote the heck out of these services. And there is the authoritative Rodale history over the past 80 years. Everyone knows compost has to be an integral part of a conscientiously applied organic lawn care program. Everyone knows that except me. I believe any improvement following the use of compost to be coincidental with the increased emphasis and attention paid to the land where the compost was applied. I do believe there is a beneficial "micro mulching" effect, but not much else. In the article you referenced, Dr Ingham says, "Compost is the mix of plant materials." Even if you read the rest of the context, she never gets more explanatory. Compost is a mix of decomposed plant AND ANIMAL materials. How decomposed is it? Pretty darned decomposed. In fact I refer to it as a pile of depleted fertilizer materials. The stuff going in may have been weak in the protein department, but it is definitely weak in the protein department following months of aerobic decomposition. I might also mention that Dr Ingham has profitable products and services to sell. Part of the problem is, since the 1990s when all these hundred thousand species of soil microbes were discovered, there hasn't been enough time to run proper studies of the effects of the various foodstuffs in improving the soil. The foodstuffs used for the popular organic fertilizers include human waste (such as Milorganite and Hou-actinite), soybean meal, cottonseed meal, corn meal, corn gluten meal, flax meal, used coffee grounds, alfalfa pellets, feather meal, hydrolyzed feather meal, blood meal, kelp meal, and poultry litter. All of these materials work stupendously well by themselves to improve the color, density, and growth of grass. So why would anyone waste the energy to run peer reviewed tests? Where is the profit in the results beyond what we in the trenches already know? If I can summarize: Compost is too depleted of protein to be of much value as a fertilizer Any organic fertilizer is much better than any compost, unless the compost was fortified with organic fertilizer Soil microbes are more resilient than people give them credit for. And I know some very smart folks who disagree with me on this. We'll never know until the research is done. Aeration is a poor substitute for fungal mass and miles of hyphae in the soil.
