Oh, what a helping information on yellowing leaves of jasmine from you all (Cinta, Tarev, and JB). Thanks so much. Now it is my task to find out which cause is the one that make my jasmine undertake this common symptom of yellow leaf as JB suggested. Made a closed look again on my jasmine: no Chlorosis symptom (yellow leaves never turn white and they fall as not strong); no sunburn; not turning grey; not wilting or dry or turn dark. And the only remaining cause: overwatering, pretty much lead to the situation of my jasmine as JB described: "...turn yellow starting from lower branches and the tips may turn brown and dry..." AND FALL OFF (I add this as I observed). It has been only one week since my jasmine got home. I remember I watered once when arrived, watered again after repotting, and the third time shortly after as I saw the soil's pretty dry. So, I guess that's overwatering, right? Sadly now I see more leaves turn yellow and fall off, however the vine tops are still shooting up (the highest one starts turning and turning around for nothing to hold in the air; still waiting for a trellis coming next week). Another situation I was just wondering at night in my sleep that the weather is cooling off now especially in the night. Could it be the reason of change to cause those leaves turn yellow and fall off? (can't believe it's time of Fall reason already... ) I thought jasmine is evergreen? Anyway, I am tinkering to move my jasmine in from patio tonight... I thought it doesn't like the cold? Any comment? Thank you all.
Oh, Sinta. I think I have to focus on my jasmine now. As for another fragrant vine, maybe later. But thanks.
