Hi I planted 2 Michelia figos in ground about 1 meter apart about 3years ago. They grew really well and both the plants were very healthy until now. I added some sea weed solution and slow release fertiliser in both of them for stronger growth 2 weeks ago. Now one of the plants has started shedding off a lot of healthy leaves. some of the leaves has also turned yellow.There is also a lot of new growth and that is also shedding off slowly.The other plant is doing very well and no such problems. Could any one please suggest what the problem might and if possible the solution to the same. There are some photos attached for reference. Thanks Mins13
