About Black Pine Bonsai #1

Coming home, I had all my trees washed because it’s forbidden to bring the soil from Taiwan. This is the regulation among countries to prevent the spread of plant pest. Then I opened the plastic cover of mos (soil substitute covering the root so it stays moisturized along the trip) one by one. After that all the roots that had been cleaned from mos was soaked with plant vitamin or organic fertilizer liquid for about one hour. Last thing to do was to keep the plant out of soaking liquid and planted it on the pot.

MEDIUM FOR PINE (Suitable for Casuarina=Juniperus too)
3 bg sand of 1-2 mm (do not use powder sand) +
1 bg loose soil (Do not use sticky soil such as clay, etc.) +
1 bg humus (or compost to substitute humus).
After being mixed well, it can be used to plant (you can see how to plant in a pot on article of Loa Variegata). I’ve got a little story about sands. In around 1990 in Indonesia there has been found a kind of pit sand (pasir gunung) from perimeter of Malang, so that it is called pasir Malang (Malang pit sand). This kind of sand was found by hobbyist and raw-material (bakalan) bonsai hunter in the nature. The specialty of this sand is clean and has no powder or waste. We may say that it’s been free from pests and germs that are usually found on soil or pit sand. So there’s no need to have it washed it anymore and it has pores to keep water and air. There are several kinds of plant that are better being planted on this sand rather than any other media, i.e. Santigi (Phempis Acidula), Cemara Udang (Casuarina Equisetifolia), Black Pine, Cemara, etc. Naturally Malang pit sand is beneficial for bonsai hobbyists and some devotees of ornamental plants such as cactus, adenium, sansivera, etc. Then I use this pit sand as composite for media to plant Black Pine and other bonsai.
