This is an interesting and helpful subject.

I have flying dragon and C35 rootstock seeds and will t-bud nagami kumquats on them later when they are ready.

We were always using standart soil of our farm before, but this time I want to use a better mix.I was recommended to use this product; SAB Substrate 2.
Do any of you have an experience with this product, how may I use it?
I am not sure if I need to fill my container only with this product or do I need to mix it with other stuff like perlit, leonardit etc...

Thanks,

Meyer Lemon, the product will be fine to use, but the product is really nothing more than the common commercial greenhouse grade of peat moss. The added fertilizer (NPK) in the product is a pre-charge germination level charge, again most all greenhouse grade peat contains pre-charged nutrients. The "ecologically compatible re-moistening device" is a fancy way of saying that they have added a wetting agent to help ease the products wetting, again every supplier does the same. Lastly the manufacture has added lime to adjust the pH to the 5.5 - 6 level, again all manufactures do the same. Therefore, in a word, it is a good product but no better or no worse than any other bag of greenhouse grade peat moss. To answer your question, you cannot use this as 100 percent of your tree's growth mix (potting soil). Pure peat moss will soon compact and loose most all of it aeration, and drainage. A good commonly used commercial mix for containerized trees is 3-parts conifer bark, 1 part peat moss (your product), and 1 part COARSE sand (builders sand, not play sand). Lastly the pre-charge of fertilizer that is added to peat moss is enough to last only for 2 or 3 waterings. - Millet

Thanks a lot Millet, this is another detailed reply answering my question

I get what you say about the product.I can use it as a standart good peat moss but I'll not expect a miracle

After your answer, I searched the forum again and noticed you already mentioned that mix many times, sorry for that.
Peat moss and coarse sand is no problem but I am not sure if I will be able to find a ready product as conifer bark here.I've never seen it before.
I will check greenhouses around to see if they have it.

If I can't find conifer bark ready to use, I will ask your opinions on an alternative.

Thanks again

Conifer bark, is also commonly called Pine bark or Fir bark, you can also use Coconut Husks 1/2 or 1-inch chips (better than Conifer barks), or you can use Cedar bark. I would not use the bark from a hard wood tree, as hard woods usually contain to much manganese. - Millet

Thanks a lot Millet

I am searching for the barks but I found 2 products named Cocopeat and Cocopeat Husk Chips. I guess these are what you were writing about in your last post.I talked to the seller and products are ready to purchase.

So I can use these prodcuts instead of Conifer bark and you say, these are even better, right?

I will compare prices since I will use these mix in commercial containers.

Thanks again,

Coco peat is used similar to peat moss, Coconut Husk Chips (CHC) will last approximately 3 or 4 times longer that conifer bark chips. However, the one draw back to CHC is that they have to be pretreated to remove the soluble salts before they can be used. See the link below for instruction of how to pretreat CHC before use. The link is actually written by an orchid grower, but the CHC pretreatment is exactly the same for Citrus trees. http://www.ladyslipper.com/coco3.htm

Thanks Millet, I will read it
