MeyerMilke, Every medium no matter how well draining, has some type of a perched water table at their bottom. Even bottomless containers have a perched water table. Twenty years ago, when I purchased my first citrus tree, I planted that tree in what is now called a gritty type of mix. I did not care for that type of mix at all. Later I grew some trees in a CHC medium (Coconut husk-peat), it was not all that bad. However, after a year or so the CHC mix became s little mushy and begin to hold excess water. After a couple years growing in CHC, I begun growing my citrus trees in the 5-1-1 mix. I can say that the 5-1-1 mix is a good medium, and container grown citrus trees can be successfully grown in it. I like that mix. At this time I probably had 20 +- citrus trees, all in 5-1-1. Because I was having retaliative success using it, I stayed with it until a couple year ago. Then about two + years ago Lazz, a very well known, long time citrus grower, and former owner of the Citrus Growers website, recommended that I should try Miracle Grow Garden Soil (NOTE: not Miracle Grow Potting Soil) as he was having excellent results with his container grown collection. Lazz grows both in the ground and in containers. I presently have around 25 - 30 or so citrus trees growing in MGGS, plus 50+- container pineapple plants. Just a couple weeks ago I transplanted many of the original MGGS trees from 5-gallon air root pruning containers into 13 gallon air root pruning containers. You can find a previous thread on this site titled "Better Than I ever Hoped For", about the transplanting. Upon transplanting, I was amazed how well the MGGS, now two years old, held up, it looked almost new. I also noticed that after two years it had only sunk approximately 1/2 inch below the container's rim. Therefore, I simply removed the trees from the original container and placed them in their new 13 gallon home, and then simply filled in around the edges with additional MGGS. Over the two years they grew in the medium, the medium continued to have excellent drainage, and therefore provided the tree with good root zone aeration. For me both the 5-1-1 and the MGGS offer a good substrate for growing container grown trees. The huge advantage that MGGS offers is the ease of planting, as I use MGGS straight out of the bag. Its a lot easier to locate, and is a lot less expensive then the 5-1-1. I have NEVER lost a tree growing in a MGGS medium. Today I know many more people now using MGGS, and I can report 100% of them are happy they found out about the product. I personally recommend it. . Thanks for joining the forum, you will be a valuable member. I used to be a Garden Web member, and by the way so was Lazz,and I have see some of your postings, but that was some years ago. - Millet
