Ohhh I see Malaysia is a bit different from me When #4 was in flowering for me Sun time here at longest is about 15.75 hours buds where easy to see and nearly ready to open and did so with lesser sun light time and finished flowering 12 days later. Temps where in the 80 - 92 F range at the same sun times mentioned and the time of day mine opened was 16:00 hours to 23:00 hours For now I can say your heaviest rain season might be a bit much for #4 although the soil you have it in does look nice enough to drain fast enough. Again odd #4 Messeb like water more than most succulents but doesn't like wet roots for to long of time in days the top will rot out on you if to wet to long. Your other plants would certainly benefit with a lot less water than #4 can handle Other than a season rain over watering concern I have think you'll do very well with yours. As caution I think it would be best if you could provide a tarp or tent for some over head covering during your heavy tropical rain season over the entire garden bed. I and others here appreciate you and want to see your plants in there best of flowering later too. In all honesty it's best to tell you to talk to some of your local people with the same succulent garden passion as yours and ask them what they do.

Fungus gnats appear when you use a peat based soil that remains wet for too long. Looking at your pictures, this is where they came from. This will also cause your leaves to get mushy from over-watering. Your mix looks very wet and water retentive so I am guessing this is what is happening here. If you were to pull your plant out you will probably notice there are not a lot of roots and you possibly have some that are black (rotting). It looks like your plant is also etiolated due to lack of adequate lighting. They will stretch out and get leggy in search of sunlight. A combination of these things is what is causing your plant distress. -Erica

6" is quite large for such a small plant. You could plant couple together if that's all you have. Problem with over-potting is that the soil will take much longer to dry out. It may look dry on surface, but still be too wet inside around root ball. It would be better to go to just 4" if single. It would be better to add some inorganic materials to your cactus soil (many of us don't use it at all, but some ppl do). If you can get some perlite, pumice, scoria, grit, turface - any or few of these would be great addition to your soil. Soil (organic material) should be kept to max 1/3rd of the total volume, even less for best drainage.

Hey all! If you guys read what I replied to the comments, I placed all my succulents outside cause we had a really hot week then. We had a cold night forecast though of around 28 degrees and I was planning to take them back inside but had an emergency and wasn't able to come home. That following day I checked them out and almost all them them had mushy and soggy leaves. Some branches even started falling down I am so heartbroken. There are some that survived you can tell by the color. My question is this, (picture) some of them turned this color but isn't soft or soggy to the touch. Is this a sign that it's going to survive too? Can anyone share measures to somehow revive them? You will notice he leaves on the left (of this particular jade on the blue pot) are still very green. The ones on the middle are pale or kind of brownish and the branch on the right has bowed down. Will it help to cut branches that seem hopeless?
