Still in shock after transplant. Trim off yellowing leaves, water daily and keep in shades.

Harvest some vege leaves before they turn old.

The fungus/dark spots seems to be under control with new leaves growing. I also water the plant less often as I suspect overwatering.

Another plant dying.

Some yellow leaves start to appear on the newly transplanted pandan, even though it is protected from direct sunlight.

I cut off the yellow leaves, put it at even more shady area and water it slightly.

Drench the pot soil with Hydrogen Peroxide <1% (mix 4 part water with Hydrogen Peroxide 3%).

So tiny gnats will try to jump around to escape. You can spray them with Hydrogen Peroxide or Home-made Neem Oil Pesticides.

The downsides of using Hydrogen Peroxide is killing all the microbes in the soil (both good and bad).

Hydrogen Peroxide helps with root rot (caused by fungi and bacteria in the soil, also caused by excessive moisture in the soil due to overwatering), by killing fungi and bacteria in the soil and restore oxygen. The extra oxygen also help the roots to absorb more nutrient.

I add mulch on top of the soil to discourage gnats to continue to lay eggs.
