Tuan,
You have to tell me your secret to keeping Chojubai alive in Socal. We talked about this before you came on Saturday and we don't seem to be having any luck so you are the expert.
Hi Ian,
Sorry to miss the first period of last meeting!
Thanks for applauding me!
As you may well know, chojubai prefer cool, humidity to hot, dry environment. I am living in Inland Empire which is hot and dry in the summer. It is similar to low desert area.
Because of it, I have to place the chojubai in the site which has relative cool in the garden.
It is better to place the plant in the North side, but I don't have misty system to supply humidity in this area yet. So, the second choice is in the East side. I did not let the plant have direct contact to the sunlight. It has been receiving the indirect sunlight only (to me, Chojubai leaves are too thin and much less cutin comparing to the regular Japanese flowering quince. Because of this, the leaves will be burnt in no time under strong sunlight in my area -----> plant photosynthesis will be reduced seriously -------> plant health will go down hill ----> death can not be avoid!). I place the plant under the shade of the landscape tree.
To give the humidity, I have been using the automatic timer misting system. In the summer, I let it run 4 times a day: at 6 am, noon, 3 pm and 5 pm. At noon and 3pm, run 2 minutes each. At other times, run 5 minutes each.
At this time, I let it stay in the North side to let much cooler temperature ( I don't need humidity for the plant at this time since it is much less dry here).
But like I said, this is the first year I have it, so I have to wait one more year to find out if it will be ok or not!
Hope it will help you!
