    I have been awarded a contract to plant 5 Large Jap. Maples which will be planted in very large ( say 200+ gallon) concrete pots which are located in the lobby os an office building.

    As for the soil medium, I am using a general purpose topsoil with a light amount of organic humus. I was wondering if the large concrete planters need to be able to have some type of drainage, or should some absorbing material be put in first. My concern is that a fungus or rotting may occur. Or will total soil be OK?

    You need to provide drainage. The simplest way is to place gravel in the bottom, covered with a layer of woven landscape fabric. There are also products such as Miradrain by Mirafi that can be installed around the sides of the container to provide drainage.
     
  3. Be careful on the warranty of the jap maples.We purchase ours from sanders's in tulsa. But they dont do very well in the ozarks or oklahoma.Make sure you have the best jap you can buy.The life span here for jap maples is 10 years

    If you feel like brushing up, there is a book plainly titled JAPANESE MAPLES, by an expert on them.

    I sold mine, and don't remember the author, but it should be easy for a bookstore to look up.

    A big store probably stocks it, and you could skim through it in the store. Its about $45.

    One thing, good soil is probably better than sandy soil. Sand takes up space. Its basically tiny rock.

    I'd probably go the soil and organic matter route.

    Are you planting these indoors?

    Thanks for the input. I will line the bottom with the gravel and the fabric.

    These are inside a lobby and the light requirements will work for this particular situation. I will take some photos to provide later.

    Thanks,

    You may want to use some Hortisorb in the pots. These little cristals hold a lot of water and release it as the soil drys out.

    Don't Japanese Maples need a dormant period that they will not get indoors? I don't know, but I would think so. Does anyone know from experience if they will survive a year 'round situation? I would think not.

    I guess i needed to include more detail. These large concrete planters are also able to be rolled around and will pe placed in a protected courtyard during the cooler months. This was one of the first concerns that I also had. This company has lots of money, and will likely have other decorating plans for the space in the winter. Maybe I can sell them some Christmas trees at that time :p

    Are the concrete pots new?? I made hyper tuffa pots (which are similar to concrete), but before being able to plant plants in them, the pots have to be flushed out repeatedly because of a "toxic" substance within concrete (sorry i can't remember the name). Anyways, I wouldn't want all the jap. maples to die because of a reason such as that. Just my two cents...
