One gardener I correspond with that lives in the San Diego area (very alkaline soil) tells me that he must add calcitic lime to his garden each year or he will have Blossom End Rot and other problems. So it may well be that in soils that tend to be alkaline the Calcium Carbonate (lime) is not very readily available to plants in which case more may well need to be added so it is. However, which lime you use also depends on what your soil needs and if it needs some magnesium then dolomitic lime probably is what is needed. If Calcium Carbonate is what may be needed then a calcitic lime should be applied. But which is used needs to be applied in the right amount or it will do little good. Whether gypsum would be any benefit depends on many things about the soil also. More than likely applying enough Epsom Salts (Magnesium Sulfate) to your soil to make much difference would probably be cost prohibitive.

I haven't noticed any problems. I try to toss everything in together because there's too many plants to feed and it takes a long time. It's certainly possible that some of the products might interact or neutralize each other but the plants seem happy so I've never really given it a thought. B1 is given by itself because I use that for transplanting and stressed plants, otherwise I dump everything in the barrel at once. lol Since the brugs are fed weekly I put their food in a hose end sprayer 3 weeks out of the month. It's the monthly feedings that get lumped together. Karyn

I've never posted in this forum, and I don't want to spend a lot of time introducing myself, but since 2002 I have moderated three organic lawn care forums around the Internet. I live in San Antonio and have noticed the mention of Malcolm Beck in another post by strawberryhill. That made me feel a little at home here. I have met Beck on many occasions as he had a monthly organic gardening community meeting running for a year or so in the early 2000s. Malcolm is considered the father of organic gardening in our part of Texas and has a huge following, so it is nice to see his mention in this forum. I have an observation or two (or a lot more) on this forum, but in the context of this thread, I'd like to hold my keyboard back somewhat. All my focus has been in lawns for these years, but in the course of many meetings and keeping my ear to the ground, I have learned a little about how the community cares for roses. First of all, to answer a question asked way up on this, the application rate for molasses over an area is 1 gallon per acre which equates to 3 ounces per 1,000 square feet. For spraying roses, the San Antonio organic community typically uses 3 ounces of molasses along with 3 ounces of liquid seaweed per gallon of water. Spray the undersides of the leaves and all surfaces of the plant. What this apparently does is feed the microbes living on the outside of the plant and those microbes help ward off sucking pests. If you add 3 ounces of garlic juice to the mix, it helps keep thrips off the roses. If you have not already discovered it, check your local farm and ranch co-op to see if they sell bulk molasses. Bulk molasses is sold by the pound. I think the current price is around $0.15 per pound which equates to about a $1.50 per gallon. This stuff is feed grade molasses, not food grade. Also I'd like to respond to somethings strawberryhill said above. This might be long so get comfortable. I have the same good results breaking up my rock hard dolomitic/limestone clay here with gypsum. I was digging a hole and stopped at rock-hard limestone at the bottom. I sprinkled gypsum, poured some water, and took a few hours break. I came back, and the bottom was softened enough to fish out more stones. I would highly suggest you get a soil test done before adding anything like gypsum to your soil. The best soil test lab in the country seems to be Logan Labs in Ohio. By best I mean bang for the buck as well as reliability in their test results. For $20 you get testing done that would cost up to $100 at most university soil test facilities. At LL that is their normal test so they are very experienced to doing it. At a university these would be considered "extra" and they'd have to order chemicals and relearn how to do the test. And in general, adding gypsum type calcium to a soil that is already calcareous seems like the wrong approach. In the past I dumped peat moss (pH 4), or alfalfa meal (pH 5.7) at the bottom of the hole. BIG MISTAKE ! Those fine particles glued up with my sticky clay ... and became concrete. University of California Extension listed 1 ton of gypsum as equivalent to 5.38 ton of sulfur. The only thing I would put in the bottom of the hole would be micorrhizal fungi and possibly rock phosphate. I also tested how sulfur soften my clay ... takes way longer than gypsum. It took at least one month for the sulfur to have an effect. A bit of gypsum is 5 times more effective than sulfur to soften clay, also to de-salt saline soil. First of all I would disagree with making this sound like a blanket statement. Gypsum does not soften soil except in special circumstances. Sulfur is a fungicide which kills the beneficial fungi which normally soften soil. So sulfur would be a bad idea for softening the soil. In the lawn community there are commercial surfactants sold to soften soil for professional sports complexes and golf courses. The cost roughly $70 per gallon which is out of reach for most home owners, but not out of reach for one of the moderators I worked with for several years. He also happens to be a soap hobbyist and junior chemist. Basically he tried the various surfactant materials and found they worked fantastic. Then he reverse engineered them and examined the ingredients. Then he bought those ingredients on eBay and started experimenting. As his basic tool he uses a screwdriver. Stab the screwdriver into the ground and measure how deep it goes. Then soften the soil and measure the penetration. Then along I came and simplified his approach. I have been recommending the use of baby shampoo at the rate of 3 ounces per 1,000 square feet. Apply to the soil and immediately follow up with 1 inch of water. A week later give another inch of water. A week after that reapply the shampoo and inch of water. That should set up the soil environment to favor the beneficial fungi which normally keep the soil soft. In the typical lawn this has worked across the country. In my yard after watering my soil is almost too soft to walk on without turning an ankle. That moderator experimented with increasing amounts of his surfactant to see how deep his soil would soften. He got up to about 50 ounces of surfactant per 1,000 square feet every week for months. There was no problem to the lawn (but I would redo this for roses to be sure). As far as softness, basically he ran out of screwdriver and had to resort to other measuring devices. I believe he was at a comfortable 20 inches or so of pretty soft soil (he's north of Philly). Another mod had a tree limb bury itself 27 inches deep in his lawn. So I would highly recommend trying this. Molasses & gypsum & sulfate of potash to lower alkaline water: It works better than vinegar, I wilted a few roses by watering plus vinegar in high heat. I tried used lemons last year, didn't green up. Molasses is thick so I dilute molasses with water, before adding the other 2 powders and shake the bottle. Then I use 1 teaspoon of that pre-mixed solution per 2 gallons water. Here's the basics if used from concentrated. Again making the blanket statement that gypsum is good for the soil is not going to work for many people. Certainly it won't work in Texas where most of the soil is limestone with a pH of 8.0. Normally we use vinegar instead of RoundUp to kill plants. Spraying it on plants is one thing (non selective herbicide), but using it on the soil is another (carbohydrate bacteria food). And I'm also interested in the mention and use of potassium sulfate (sulfate of potash). That is not an organic material. That is salt. I realize it is used in every commercially branded organic fertilizer, but that is why I never use those. So I'm curious why it is so prominent in an organic forum and what it does to enhance rose health or production. One teaspoon of thick molasses per 2 gallons of water, beyond that will turn the edge of leaves brownish (I did that to Gina's rose, most likely from the 20% iron of molasses). Wholesome Organics (zero salt) and Plantation brand (low-salt) also has 15% calcium and 20% potassium. I have not heard of any problems using 3 ounces of molasses per gallon. I'll check into this further. The purpose of adding sulfate of potash and calcium sulfate (gypsum) is to utilize the sulfur part to green up roses, and neutralize the lime in tap water. Again this only applies to calcarious soils, but I believe there is a much better material to use. Sulfur is a fungicide surpassed only in potency by most sulfates. If you want to harden your soil, the first thing you should use to kill the beneficial fungi is sulfates. If you have calcarious soil, you'll be better off using greensand (if you can find it) and mulching with a shredded tree mulch. As the mulch decomposes the organic humic acids from that process will do more to acidify your soil than sulfur. Any tree trimmer has the material you need. One teaspoon of gypsum powder per gallon of water, beyond that will make plants more prone to fungal diseases (rust and black spots). Too much calcium drives down potassium, necessary for disease-prevention. Instead scatter whole ground corn meal (the kind you cook with or animal feed) around the base of your roses. Cornmeal attracts the trichoderma (try koh DER mah) fungus. Trichoderma is a predatory fungus which feeds on the cell walls of other fungi. This research was done on peanuts at Texas A&M in Stephenville. They have suppressed the research and recently took it off the web. Basically what they found was that peanuts, which normally develop a fungal disease over the course of a season, had to be rotated with a non-fungal crop every year. By using ordinary corn meal on the ground (20 pounds per 1,000 square feet), they were able to use the same soil to grow peanuts year after year. I tried it on my roses and the PM and black spot disappeared in a 3 weeks. Corn meal is also a weak organic fertilizer so there is certainly no harm to try this approach. There was a lot more about the use of potassium sulfate and gypsum, so while I believe those are not good for an organic garden, I am interested to know why y'all thing they are.

Kevin gave me some Girl Scout cookies yesterday that a co-worker of his gave him - Kevin didn't want them because they are oatmeal raisin, and he doesn't like raisins. I tried eating one of them and was very put off by the salty taste of it. I also have some shortbread cookies from TJ's, and they have no salt in them, and taste infinitely better. I hate salt in cookies - there is enough salty flavor from the baking soda. I only buy salted butter by accident, which I did last week-end, but I will use in only in savory dishes that require salt and will not use it for desserts or anything sweet. For me, salt ruins a lot of dishes and I consider it to be a flavor destroyer rather than enhancer when it comes to dishes that are sweet, and that includes vegetables that taste sweet. I understand that some people (such as Ina Garten) want everything to tasty salty, but for me salt makes a lot of dishes unpalatable. Ina puts salt in her shortbread cookies, which for me is a major no-no. I do not understand why some people think that salt belongs in every recipe. Perhaps they have a salt addiction.
