"Did you later start using the gritty mix and abandon the basic mix?" No. I use the gritty mix for plants that will be in the same soil for more than a single growth cycle. I use the 5:1:1 mix for all my veggies and display containers for the decks & gardens. I usually turn the 5:1:1 mix into the gardens, beds, or the compost pile at the end of the season. You got the gritty mix right, but The 5:1:1 mix is 5 parts partially composted pine bark fines 1 part sphagnum peat 1 part perlite garden lime The granite for the gritty mix is usually found at rural elevators/feed stores under the name "Gran-I-Grit" (grower size) or Cherry Stone (#2 size).

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.

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

One thing we need to respect is another's perspective. One grower might look at growing with the attitude that nothing is going to stand in the way of my reducing the effects of every limiting factor that impact my plants' growth and vitality. Growers like this tend to look at growing from the plant's perspective. Another grower might not be interested in entertaining the thought of changing anything, so long as the plant seems to be doing well enough. I've found this to be especially true if the chance involves more effort or expense - this is more a view from the grower's perspective - how it affects ME, rather than the plant. Neither perspective is wrong, they're just different ways of looking at things and ordering priorities. We all go through the same considerations, but some people come down on the plant's side & others on the grower's side. A prime example of this can be seen in the form of people arguing vehemently against the effort involved in finding ingredients and then making either the 5:1:1 mix or gritty mix. Almost always, the argument against comes from growers who have never tried either mix, and are content with the results they get from a from-the-bag mix because it's easy. Not all of us orders our priorities in that fashion. My good enough may be her poor; and good may in fact not be good enough for her. I know a lot of people like that and admire them for their desire for continual improvement. Rachel's question is a very good one, and her commentary clearly illustrates she's been thinking the issue through (from the plant's perspective) and looking for some input. Any teacher would give her high marks for that. I say often that our plants are already genetically programmed to grow to be beautiful specimens. The ONLY thing we can do to help is to be proactive in continually reducing the effects of ALL things that have the potential to limit growth/vitality. Remember, if everything is perfect except ONE thing, that single limitation can wreck the entire growing experience. One thing for Rachel to consider is that water in plunged pots behaves differently than it does in conventional container culture. That they are partially buried turns them into mini raised beds, hydrologically speaking. As long as they are not plunged into clay, the earth will quickly wick any perched water from the soil she chooses; so she has roughly the same potential for growth/vitality using soils that would otherwise be too heavy (water retentive) to be well suited to container growing as she does if using the gritty mix or the 5:1:1 mix. Since there is little notable loss in potential, based on her growing method, if using a heavier soil, we need to look to the interval between when the pots are lifted and moved indoors and when they're returned to the garden or beds and buried. Normally, there would be considerable concern over accumulating salts during the over-wintering period; this, as a result of having to water a heavy soil in small sips to avoid the soil being wet for any extended period. Since I believe she will be watering rather infrequently, it may not be a serious issue. Just a guess - if she's watering less often than every two weeks, I think she should be ok until repot time. Also, if she's willing to cheat the state out of a little rain water and use that to water with, it pretty much makes it a nonissue. I think Rachel's free to use a heavier soil if she wants to, and it shouldn't have any notable effect on her plants. If she has a suitable bark on hand - maybe something like a 5:2or3:1 bark:peat:perlite would be good - or even a bagged soil. The only real disadvantage to a peaty soil for this particular application is that it makes repotting more difficult. So - there's a little about perspectives and growing for you to consider. I hope there's enough there for you to set course with a little greater degree of certainty. Time to get out in the yard before it gets too hot again. It looks like another day that will be pushing 100*. Take care - thanks for the kind words. ;-) Al
