Land and Water Pots

Not sure where to put this, but I am not a potter.
You may have seen regular oval pots that some commercial bonsai artists turn into land and water pots by building a miniature stone wall across them and sealing the drain hole at that end. The one I have is probably from Suthin. It is a little too small for a bonsai, but perfect for a kusamono. I will post a picture when I get around to it, if you wish.
I planted mine and was going to display it, but when I filled the pond with water, it all seeped away. I found a product called Water-Lox. It is labeled for sealing both wood and masonry. It makes stones shiny, but if they are going to be underwater, it doesn't matter. If the pot is already planted, you have to wait until the planting is pretty dry, but not dying. I poured a little Water-Lox into the bottom of the pond, and applied it to the wall several times. Now the pond holds water. If the Kitschomatic goes off, it is displayed with a little fisherman.

This is my first successful kusamono. At least it is successful in that the plants survived.   



At this angle you can't really see the pond at the right end with the little stone wall. The main plant is Pogonatherum crinitum, dwarf bamboo grass. It is a true grass from southeast Asia, but it gives a bamboo like appearance. The variegated form is more elegant. Although there are several grasses used for kusamono and shitakusa, this species is said to be the only true grass that will grow indoors indefinitely. During the winter it grows right under the fluorescent tubes. It does not tolerate low humidity well. During the summer it grows outdoors in part sun. I give it half strength fertilizer year round. It is a clumper, not a runner, so very suitable for group plantings. There is a small specimen of dwarf true myrtle peeking out from behind. The ground cover is baby tears.

Very nice Iris! I could see it used in summer along with a willow cascade. refreshing....like a cool breeze!
