Comments (28)hello this forum mayb closed i am looking for only natural and organic growing mediums, i have used lava rock on and of since about 1983, the first time i used it right as it came from the bag that lasted till about 88, i got some free time on my hands and i pulverized my lava it was about 2 - 5 gal buckets worth when i gave up i still have that batch i just rinse it well if i want to use it i have had real good luck just using it as a normal water as needed medium, our thinking was such great things come from the islands and had seen the great flowers there , pinapples come from there so,,, why not grow in it as long as i keep it well drained and no obstructions on the drain holes it has been some good medium, but i never really had much time to actualy set up a real hydroponics system like u see now days it was just ur bare knuckles pump the water in and cover the medium and drain it out well, since then i have been tryn to utilize some water and slopes and grow fish and plants in our ponds and i have ignored lava rock till the last few yrs but now i am really looking into growing only organic in truly only organic containers and anything touching the water and its been very tricky since my wife does cancer treatments and my background is environmental i have looked at cancers and sickness as a result of what we eat and whats in all of what we digest and the containers that touch it and what its grown in and watered with,,, so,, my point? i have used lava rock but consider it somewhat inert but with my chemistry background and knowing whats in all the water and whats gonna be in the fish excretions from gills and excrement's it will have some affect on anything in lava rock that might dissolve up to the point my fish algae coats it with that slim, so my concern? i saw one blog where the blogger says lava rock gives off dangerous chemicals ,,, but its blog to me seemed to b pushing claycorn ,,yet its man made from who knows what and is imported from china i also see that it starts out and may stay with a p h of 8 my lava rock in and 7 ph filtered tap thru 3 charcoal filters shows 8 depending on whose eyes u use, ,,i see where the most fertile lands on earth are in volcanic soil but upon checking cancer rates in these areas i find that many say they have high thyroid cancers in those areas of course the people are exposed to more than the soil yet i found a very few isolated volcanic areas where no cancer existed but they say its from the general diet high in certain elements,, since lava rock numbers i have seen imply 66% silica, 16% aluminum. 10% iron,, lists only 10 total elements i am wondering if i should be concerned with the aluminum, and its possible affects on humans causing dementia, n Alzheimer and no i do not want to hear its a metal and it will not react i am talking pure submersion in my fish ponds and in my grow beds ,, i have stayed with what i think is river rock for now since thats what i ve always used for fish, (and its probly all conglomerate of marble (igneous limestone), granite, quartz, limestone, with one pebble or 2 or lava rock) but since i am planning on eating the fish and i am tryn to remove all man made items such as plastics, vinyls, pond liners, additives in my fish food and meds and hormones not used and all fish treatments removed ( if they die they get blended for chum), are there any other obsessive people who can give me any reason to not use lava rock over man made clay balls for grow medium my brother n law is sure that the clay balls have been developed by the professionals, my son who is helping with the learning is too young to do anything except as what the hell are ur talking about old man? i have not finalized my choices but i see the professionals as only there to part me with my money and sell me some snake oil when it comes to clay made pellets, ,, so do i have to worry about the aluminum, or any of the other 7 items aside from the silica i know i should not breath when i pound it to a pulp, i am tryn to be as true and pure organic as can knownly be and growing inside greenhouses and enclosed ponds not sure how i m gonna get the birth control pills outs the water if its not truly well water but has been slipped in from the lake if my charcoal filters won t remove it except to maybe us my springs that have p h of 6 and drill my own well, of course when i add the wrong things to drop the ph it actually draws out more of my alkalies but i have probly always grown my crops in a ten due to growing in this east texas iron ore and sand , and in central texas dirt and here i have always added gypsum to cancel out the chlorine added to the tap water if you can sort this out and it gets past censors please let me no if anyone out there can shed some lite on my determination to use all lava rock and river rock and white marble or limestone rock...See MoreAzomite, red lava rock, manure, bone meal, worm castings
Comments (36)Red lava rock, or red-lava-sand, is a great source of iron and potassium. pH of red-lava-rock is 8.2. Red-lava rock is OK like 3 or 4 pieces, too much will UP the soil pH, plus prevent water from soaking through. I went to my neighbor when it was above 90 F one summer. She mulched her roses with THICK layer of black lava rock. I touched them, and they are the same temp. as our rock-hard-clay. She overkilled on the lava-rock: too much potassium drove down nitrogen, so her roses didn't have much leaves, lots of blooms. I would use no more than 3 pieces per rose .. too much and one gets iron-burnt (brown-spot). http://forums.gardenweb.com/discussions/1539970/lava-rock-as-mulch ocdgardener(8) From what I understand about Lava Rocks is: Lava rock breaks down into Lava Sand. From all the sand in the bags I know it happens! Lava Sand is recommended as a soil amendment to HOLD MOISTURE. Now, the only thing I'm not sure about is temperature. I did notice though oddly enough last night when I got home from work the plants in the same bed mulched with cedar were wilting, the plants surrounded by lava were not. Here's the positives I've found thus far. On a slope where my bed is, compost, and every thing else added at the base of the plants washes down to the bottom and is replaced with bare soil. I have to add mulch over and over because it all slides away. The Lava Rocks are not only holding the compost in place but are keeping me from having bare soil. I know it does because we had a heavy rain this morning and I looked and everything was in place! --Not the usual bare soil I see after a rain! I think I should explain how I'm using the rock. I'm taking one rock at a time and pressing it into the soil. When you think of lava rocks as a mulch I think most people tend to imagine it piled up. ocdgardener(8) oh and btw you can't really see that much of the rock anyway - because the plants cover them. Example: This is what the yard looks like in the spring. ocdgardener(8) Update on the lava rock! I bought a soil thermoter and tested the temps. Although not lower, the temps were pretty close to the same by a degree. Also, I have calendulas blooming in the bed in the HEAT of summer. I've never had that before! mrwsm_yahoo_com Lava Rock has low thermal mass. It does not retain heat. Lava Rock keeps the soil soft like mulch, so if there is a weed, no problem, it pulls really easy. I prefer red lava rock, although I have both. Never put plastic underneath it! It keeps most weeds out as is. rickjones I don't know what happened to my original post, but here is a short repeat. LAVA ROCKS ARE WONDERFUL PLANTERS, ESPECIALLY IN THE EXTREME HEAT OF THE MOHAVE DESERT. Yup. I build and use cedar planters and window boxes all over my home, they are great, but do not compare with the flowers grown in the lava rocks that I hollow out and plant a variety of species in. Plants in these rocks see temps to 120 degress in our summers and do just fine! They retain moisture, cool with the air temps, and fertilize plants naturally. I don't use lava rock for bedding, I can see the problems with that. But as a planter? The best planter I have ever had. AND, no maintenance, and years of use looking great. jocoreed_yahoo_com Anyone who questions the ability of lava rock as a growing medium needs to come visit our islands out here in the Pacific. Our Hawaiian islands are completely volcanic is soil and sediment, covered in pure lava rock, and we have the most beautiful plants, trees, produce, and the like. Lava rock and volcanic soil is some of the most nutrient friendly planting medium on earth and is porous enough that it allows for good oxygenation and water flow. Come visit our islands and then come back and post how it's horrible to grow anything in volcanic rock or lava sand. Just my two cents : ) Aloooooha! http://forums.gardenweb.com/discussions/1539970/lava-rock-as-mulch...See MoreHow the heck am I supposed to get rid of all these lava rocks?
Comments (6)id tell you to move ... but .. well .. lol.. that isnt going to happen ... the easiest way to get them up ... would be with the checkbook ... trust me on that ... lol i had to remove white whatever ... with a rake.. manure shovel.. garden sieve and mostly by hand.. it took me a month ... to do a 6 by 10 foot area ... just outside the front door ........ not to mention they couldnt be dug out .. because of landscape plastic underneath .. what a nightmare ... [i raked the loose rocks.. onto the flat shovel to put them in the sieve] but one thing comes to mind... you have a wooden house .. that needs to be painted every few years ... if this is just 3 feet or so ... consider leaving it to aid maintenance .. and build your beds further out ... remember.. i keep telling you.. on acreage.. space considerations change .... also keep in mind.. foundation plantings are meant to hide the foundation.. not be planted on them ... and again.. with your increased space ... consider leaving them there ... it will be the best money ever spent.. to hire a gang of brawny men.. with the appropriate skid steer... whatever.. to do the job.. and haul it all away ... if you cant just leave it there .... please dont get frustrated when i try to help.. i cant help doing project talk.. other than like a man .... just keep in mind.. my good intentions ... ken ps: have miss dig.. ID all your utilities.. and make photo records.. to insure you dont mess around with such.. near a foundation ... for me.. it was mostly silly stupid easy to know.. except the buried cables to the barn ... didnt expect them where they were .... and there was a rather unique placement of the gas line .. not really lined up to the meter .. well maybe it wasnt easy to know ... lol.. https://www.bing.com/images/search?q=garden+sieve&FORM=HDRSC2 https://www.bing.com/images/search?q=manure+shovel&FORM=HDRSC2 https://www.bing.com/images/search?q=skid+steer&FORM=HDRSC2...See Morepat_bamaz7
