modified Al's Gritty Mix and 5.1.1 mix
Comments (12)Around here the pine bark mix at Home Depot that works is the #302 Golden Trophy bags. I've been using this for the last 4 or 5 years. The only problem is that the #302 bags vary significantly from pallet to pallet. You need to check an open bag and make sure. If the chunks are small then the entire pallet is probably OK. If not the bags in the entire pallet is not usable. I got burned this year in my first buy and had to unload all the bags to someone's in ground garden (after a harsh winter I wasn't thinking straight :-). The bags were wet and the chunks seemed small after a quick inspection but after getting them home they stunk (which I heard was not good) and had a lot of sticks and bigger chunks hidden in them. A week later I went to a different Home Depot and found a pallet of perfect #302 pine bark and loaded up as many bags that will fit into the van. A couple of years ago the good pallet of #302 was behind a bad pallet which required me to climb over the bad pallet to get to the good pallet. The employees at Home Depot must have thought I was nuts. Last year I found #302 Golden Trophy at Menards with the same pallet to pallet differences but this year Menards doesn't seem to carry it....See MoreGranite chips for Al's gritty mix?
Comments (7)In The Manna Pro Brand.. you want the Poulty grit.. Good Luck.. I have the Gran-i- grit locally and it is sold in three sizes you want the "growers size" 100 percent crushed Granite stay away from anything with crushed oyster shells in it!! Cherrystone is crushed Quartzite and you want the # 2 size. Local feed and seed store have this available.. Try Tractor Supply Stores Southern States Feed and Seed stores too Mom and Pop Feed and Seed stores can always order as well.. Hope this helps!!

Comments (16)Here is the recipe (excerpt from the thread below): *For long term (especially woody) plantings and houseplants, I use a superb soil that is extremely durable and structurally sound. The basic mix is equal parts of pine bark, Turface, and crushed granite. The gritty mix: 1 part uncomposted screened pine or fir bark (1/8-1/4") 1 part screened Turface 1 part crushed Gran-I-Grit (grower size) or #2 cherrystone 1 Tbsp gypsum per gallon of soil CRF (if desired) Source of micro-nutrients or use a fertilizer that contains all essentials I use 1/8 -1/4 tsp Epsom salts (MgSO4) per gallon of fertilizer solution when I fertilize if the fertilizer does not contain Mg (check your fertilizer - if it is soluble, it is probable it does not contain Ca or Mg. If I am using my currently favored fertilizer (I use it on everything), Dyna-Gro's Foliage-Pro in the 9-3-6 formulation, and I don't use gypsum or Epsom salts in the fertilizer solution.* http://forums2.gardenweb.com/forums/load/contain/msg0214580016564.html...See MoreAlternates for Al's Gritty Mix and 5:1:1 Mix
Comments (9)I'm just musing here & not being snippy, but I think that the 5:1:1 mix performs significantly better than peat based soils, and remains structurally sound much longer (4-5 times longer, based on all other cultural conditions being equal). The gritty mix is even better, providing greater aeration and lasting indefinitely. I'm not saying that to promote what others refer to as 'Al's Soils', only to illustrate that soils that are highly aerated and structurally stable are much preferred to peat/coir/compost-based soils for the results oriented crowd. I'm able to say this based on the hundreds of people at GW and other sites that are using these soils and some fertilizer recommendations with a degree of success that has them saying they left soils like MG or other peat-based soils and will never look back. There is a crowd that wants to make things easier (these soils are much more forgiving and easier to grow in) and appreciates the idea that their plants are growing at closer to their genetic potential. Then, there is the group that feels that what they are using is 'good enough'. I have no quarrel with how folks establish their priorities, but what I usually hear, and what I'm hearing above is 'it's too much bother'. I never try to coax anyone to use "my" soils. I only point out the considerable benefits of higher aeration and greater durability and let others decide. I respect your decisions, but at the same time I can point to the fact that what's easier for the grower and what's better for the plant are often mutually exclusive. In this case, there is an inverse relationship between effort and results, but it's not as great as it seems. Yes, there is some effort involved in finding the ingredients and making the soil, but part of that effort is negated in the fact that healthier roots make healthier plants and healthy plants are less susceptible to insects and disease, and are more productive or prolific. Include the fact that root rot and soluble salts accumulation (especially for houseplants) is something you would have to work at to achieve, and you've got a pretty good case for abandoning the heavy soils. In the end, it always almost always distills to an individual decision. Is the perceived gain worth the perceived effort. Some answer with a resounding yes, and others are not so sure or unwilling to go through the trouble. I respect any one's decision because my part in trying to help folks ends with trying to provide the best science I can so they can make up their own minds. However, if the soils didn't work considerably better than conventional soils, I'd have been handed my head long ago. ;o) Take care. Al...See Morechicagardens
