In response to DaMonkey "what's best for the plant, not the grower" idea, I have learned that it is NOT best for all plants to require watering more than once a day. There is a level of moisture/nutrient retention that will give you optimal growth of the plant. If the mix dries out faster than that, you won't get better growth even if you water 3X a day. The gas exchange turnover is less beneficial than greater absorption of water/nutrients. To the OP, I've had a similar problem but with the gritty mix drying out far too fast for some of the plants I was trying to grow in my climate (roses, citrus, mandevilla). For these plants in MY climate, moisture retention is an advantage, not a disadvantage. I have a rose in a pot of "retentive" bagged potting mix with 30 big gorgeous blooms on it right now, while a more vigorous rose (when I bought it) in gritty mix is growing poorly and has only produced 3 or 4 blooms, when during spring flush it should be more than 30 (and was more than 30 when it came in its growers pot!). Don't hesitate to use a "retentive" mix if that's what your plants, climate, and watering habits would do best with. You might also consider setting up a drip irrigation system. I have one set up just for the pots on my relatively small deck, and I so love not having to water manually. There is good info on irrigationdirect.com on designing a system. Actually, I set mine up so I could go on vacation in hot July or August without my plants all dying (and no one, no matter how good a friend, wants to come water all those plants every day, let alone twice a day!). But I was surprised to get home from vacation and see my drip-irrigated plants doing better than when I watered them manually. I'm using RainDrip components, but my impression is that they are all pretty standard (1/2" mainline, 1/4" tubing, plugs, various style emitters, etc). I have not tried any of the fertilizer dispensers to add to the automated system. However, there are growers on gardenweb that have set up auto-fertilizer-dispenser with their drip systems, so you might want to search for info if you'd rather go that route. I plan to try Osmocote Plus (24-8-16 with complete nutrients) in conjunction with my drip system this summer, rather than manual fertigation, which is work I'd rather not do. My main problem so far is that I can't find Osmocote Plus in stores (just the regular NPK-only Osmocote).

I can tell you that watering was no different for me last year in my hot and dry summer. All my plants that were in the hot sun all summer were actually holding moisture better than the peat based mixes. If you are concerned about having to water in the gritty mix and you live in an area where your soil dries out too fast, why not adjust your mix by adding more turface? Mike:-)

Am I reading that correctly - you are in Orange County, CA, right? If so and you're using county water then your water quality looks great to me. If I'm looking at the right report (see here) then you have pH ~8 with ~16 ppm of Mg and ~48 ppm of Ca and total alkalinity of ~120 (180 as CaCO3 equiv). Your alkalinity is on the high side but the rest of the report looks great (for plants, I wouldn't drink it). 1 tsp of FP in 1 gallon of water will give you ~6 ppm of Mg and ~25 ppm of Ca. I mention this because your water has a good ratio of Ca:Mg and it already has both in higher levels than you'd get with typical usage of the liquid fertilizer most people around here talk about. To answer your question directly: no. The mixes are not neutral. The gritty mix will be closer to 7 than the 5-1-1 (which will be more acidic) but *it doesn't matter.* The pH of your mix initially has very little to do with the pH levels your mix will maintain over time. In containers the soil pH will be determined mostly by the pH and alkalinity of the water you use and by the type of fertilizer you use and its ratio of ammonium to nitrate (*and* the rate at which the plant is taking up both of those nutrients which can vary depending on temperature, cultivar, etc). You should basically assume that the initial pH of the mix itself is of no consequence when it comes to determining the pH of your soil over the long term. You do need to pay attention to the initial pH but only because if you transplant something into the mix you want the roots to function reasonably well from the get-go. All this means is that you need to raise the pH of the bark or peat slightly so they are more friendly to transplants - the directions for doing that are built into the 5-1-1. I grow citrus trees in both mixes. Either will work for you and there are pluses and minuses to both. In terms of pH and nutrient availability you will find that the 5-1-1 is slightly more forgiving than the gritty mix. At your pH and alkalinity if you grow citrus trees in containers you will almost certainly develop Mn and Zn deficiency even if you use something like FP (which, again: you do not need to do based on your water quality). You could avoid this by acidulating your water or by using foliar applications of Manganase Sulfate and Zinc Sulfate (1.5 g per gallon and 1 g per gallon respectively - they can be mixed and applied to new growth on plants showing deficiencies). Just looking again at your water report you also have adequate/luxury levels of B, S, Cl, Na, & Cu. Nickel will be in your soil via the bark and or peat and you likely don't need to add any. All your water may be missing is: Mo, Zn, Mn, & Fe. Were I you I would use a straight 5-1-3 fertilizer and then manage the micros as needed myself. You will find it much cheaper than the usual suggestion. You could also go with Jack's Professional 25-5-15 High Performance and you wouldn't have to manage your micros as often (you will still get Zn and Mn deficiency at your pH unless you acidulate or use a serious acid reaction fertilizer - but then you will blow your NPK ratios). The cheapest and easiest option would be to use the Jack's (or another 5-1-3 with Mo and Fe) and then use the foliar sprays 1-3 times a year. If you acidulate your water I wouldn't use sulfuric - you have a ton of S in there already. Maybe citric or vinegar (don't use phosphoric, nitric is dangerous). This will be moderately expensive and moderately time consuming even with a chemical injector. Do yourself a favor and avoid the expense of Foliage Pro with your water. You will be correcting micro issues in any case and you have better Ca/Mg/S than the fertilizer can offer you anyway.

The Pilea Peperomioides (Chinese Money Plant) is the plant I've been wanting! I've looked everywhere (as you all know its really low inventory - most people start their own with a clipping from a friend's). Might anyone find it in their hearts to possibly cut off a little offshoot and mail it to me in NY state (USA)? I promise I would then grow it and pay it forward (or back) ! Please consider.
