Treated wood for building beds?
Comments (43)Hi Gabe from a fellow PNWer. Don't know how much further you are in the raised beds, but here's a suggestion anyway. Do you have any place locally that gathers recycled building materials? We do have such a place locally. They have old windows, doors, toilets, bricks, etc. On any given day you could find who knows what. Perhaps this is not common elsewhere, but it is here. I was thinking such a place could be quite a source for you. Prices on materials would be much more reasonably priced than at Lowes, Home Depot, etc. Cinder blocks would be quite the ticket for me. Resiliant and long lasting. Another thought would be to visit your county extension service. If there is not an office nearby that you can visit, perhaps they are on-line. I am lucky to live in a town with a local extension office and they serve a wide area of Oregon. They are really good. Not the case for everybody, so I have been told. But it's something you might look into. Our local office promotes alternative gardening for those who may need a little help. A year or two ago they displayed a big table filled with dirt. I think it was about 4 feet wide, 8 feet long. Maybe a foot deep. Obviously, such a table would stand in place once it was built. Your mom could stand and garden. For someone in a wheelchair, it could be built a bit lower to the ground. We get about 40 inches of rain a year. I don't know if they use anything special to protect the tables. The local extension agents know and practice organic gardening as much as possible as near as I have been able to tell. anyway, such a place may provide you with some good ideas. Best wishes. It's neat what you are doing for your mom. Mary...See MoreNewbie w/ some ideas
Comments (21)I suppose this post is only going to be interesting to the true compost science nerds, but I found a pretty good document written by the Australian government that indirectly discusses this issue, and includes citations. Some background first: I looked up the MSDS for the toner I use (Brother TN580): http://www.brothertoners.com/TN-550_580.pdf From the MSDS, I learned that the primary chemical component of the toner is styrene acrylate copolymer (84% by weight). After some googling, I found out that this plastic is the primary chemical of concern in toner. It is used as a binder resin (glue). After some more googling, I found an excellent document, written by the Australian government, that specifically discusses the environment impact of the chemical: http://www.nicnas.gov.au/publications/CAR/new/NA/NAFULLR/NA0000FR/NA1FR.pdf It concludes that the chemical is relatively sage from a biological and environmental viewpoint. Section 9 - the toxicological evaluation - essentially says that low levels of exposure should be fine, based on tests done on rats exposed to the chemical. The document also concludes that the chemical does not dissolve easily in water, so it should not be readily absorbed by plants or by humans. I should also add a contrasting viewpoint from: http://sustlife.com/blog/green-living/is-your-washing-up-liquid-toxic.html This chemical is used a lot in dish detergent to give it color. The blogger mentions a correlation between this chemical and cancer, among other things. However, I don't see any support for her position elsewhere, and she doesn't provide any references other than "a recent study". The side effects she mentions (headaches, etc) are related to inhalation of the powder, not digestion of the chemical. Based on this info, I've decided to start composting the shredded paper from my laser printer. I'm convinced that it's safe for the garden. If you're wondering about the other three chemicals in the toner, I've found that most of them are safe too. PMMA is another acrylate, and has very similar properties to styrene acrylate copolymer. Silicon dioxide is relatively harmless when ingested. Carbon black (5-7%) has health issues related to inhalation, but I found no studies related to the ingestion of carbon black. It's used in so many other products, particularly automobile tires, that the levels that end up in your compost are likely to be negligible compared to the amount already present in the air and soil....See MoreSo how poisonous is lantana really?
Comments (48)So sorry to hear about your friend's dog getting sick, but glad he's okay. That's quite a hefty vet bill. As our expert Tally said above usually oleanders are so bitter that it's not nibbled by dogs, but there's always an exception. Thank you for the warning and letting us know that it can happen. Sago palms are another story. It's not at all unusual to hear about dogs chewing on the seeds and dying. When he was a young pup I saw Alfie starting to chew on the new sprouts around the bottom of my 30 year old mature Sagos. I prompty cut the sprouts back and surrounded the trees with heavy black plastic and then covered the plastic with a VERY thick layer of mulch. It's been almost three years. No more sprouts and the dogs and trees are fine. It all these years my female tree has only flowered three or four times. I carefully remove the seeds before they fall....See MoreHow can I find a really good water filter
Comments (22)Arch13, I'm glad to hear it! That would be terrifying! Exactly Jake! There's dangers everywhere! And yuck for well water that has so many unknowns, can't wait to get it tested next week. Glad you get my point about chemicals being everywhere. now...do we just soak ourselves in chemicals on purpose because it's unavoidable (gotta die from something, right?)? Or do we limit the exposure to what we DO have control over? Logically (at least I'd hope so) we would naturally try to limit the risks that we can. It's pretty easy to filter the water. Is there really a risk, who knows. We know there's definitely leaching - that's been shown through various studies including those through NSF. We know there's been issues with other plastics in the past in finding hormone disruptors and other chemicals. So it's a reasonable conclusion that there could be a risk that we don't fully understand. You are free to ignore that risk, or believe that there is no risk at all. We all have to decide what risks are important to us as individuals. Neither of us are wrong, we just perceive the risk differently. You guys are referring to acute toxicity, which would be ridiculous with PEX. Small doses of chemical exposure is more likely to be a chronic and slow progressing problem that is very unlikely to ever get pinned on one thing like PEX. That's because there's probably not one culprit. It's likely a combination of our awful American lifestyle that includes processed foods, overeating, pollution, lack of exercise, and chemical exposure in every single thing we do and eat. And when you add it all up over time, you see a rise in autoimmune disease, inflammatory conditions, cancer, autism, depression, bipolar. What do we do about it? We do what we can. Can I eliminate all of it? Absolutely not. But maybe I can eliminate 20-30% of it, and that gives me peace of mind. Filtering the water, using cloth diapers on the kids, eating organic, that's what I can do. Does my peanut butter still come in a plastic jar, ugh unfortunately yes. Do I take the risk to drive my car as you pointed out, sure I do. Those aren't easy risks to eliminate. When you assess risk, you have to look at risk vs the benefit you get from continuing that risk, but also what risks are easy to eliminate and which are difficult. Then you make the changes that you can, and the changes that you feel have meaning. If you focus on trying to eliminate all risks, you'll drown in your fears. Filtering the water isn't a difficult one to attempt to eliminate. I am also a teacher and I feel myself getting into a lesson on risk analysis...lol..so I'm really done with this conversation. It was meant to be a genuine inquiry to get some advice about filtering. This debate is bogging down the other feeds of people trying to get help with their houses and unless anyone has some constructive advice on a type of filter, I'd ask you to just let it go. Patricia, Deborahhines, Decoenthusiaste, Jim Mat, and BeverlyFLADeziner...thank you for your help!...See More- 9 months ago
