About middle December of last year, I planted a flower tree (Tibouchina semidecanda Cogn in my front yard. I applied Sustane 4-6-4 from the local distributor here in Taichung to nurse my tree. In fact, it was my first time to use Sustane fertilizer and I am so surpirsed of its effects. When I brought the flower tree home, it was about 10 flower buds. After one month of applying Sustane 4-6-4 it was 40-50 flower buds! And about one week ago, when I was hoeing up weeds, I found earthworms where I did not find any before. Attached is the picture of my flower tree. It suffered from huge temperature change and weird rain and similarly light degree typhoon wind one week ago. But now it is blooming again!
