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 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.

Hi Doc!! I am sorry that i haven't been around... My Little Daschund had a terrible accident a few days ago when he was coming up the stairs. He missed a step and hit his little head wrong and instantly began to curl his feet. The Vet said he hurt his neck and to wait and see if he will come around. Well, he was paralyzed and couldn't do much to help himself, so i had to make the decision to let him go and not suffer anymore.. A hard decision because i didnt want him to leave me, but a decision made from the love that i have for him and the true love he always gave back. A true Gentleman for 13 years and he left in my arms a relaxed loved little loyal companion. This is why i have been away.. I'm still bummed and im missing my little garden buddy..But i wanted to come here and tell you why i didnt respond to your email and this post.. Thanks for the email to get me here!!! Sorry to hear about your Peace Lilly. I know how much you loved them and how you worked so hard to get the mix right and the special containers for your loved lilly. Noone could have done more than what you did to make them happy, try again someday and i bet they will be bigger and strongern(healthier) than the others. Puerto Rico sounds lovely right now.. That would probably make me smile seeing those beautitful sunsets and crystal blue water around Luquillo Beach!! Love those Coconut palms all the way down to the water. What a great local spot to visit. So you have a new Rubber Tree eh? ;-) I bet it does love the partial shade in your yard. Plants naturally love being outdside and i understand that you want to bring it inside to your office. You have the right idea to keep it away from drafts and or airconditoning vents. Constant air (chilled) causes problems and i would avoid this if possible. Also, i would keep it close to any natural light that you can, but if it is only artificial light try and see if it adjust. Give it some time because taking it from a natural enviroment to a artifical enviroment will cause any plant an adjustment period. Good Luck Tecnico and i hope all is well with you!! Enjoy that beautiful sunshine down south!! Take Care, Laura
