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.

Betina Forgot to mention: give it lots of light. It is leaning to one side - I suspect it was growing in relative dark spot and started to lean toward light source. It should start getting 'fatter' stems, darker green and rather upright. This one is same plant but monstrose - but growth pattern should be similar:

understand.. conifers are trees ... and no tree stops growing at some magical height .... most estimates with conifers are at ten years.. presume at 20.. they will be twice as big ... before i forget... do all your planning from the chairs ... the height you will be sitting there ... there is a big difference between what you see standing vs sitting ... back to the lesson ... take any common name.. and find the latin name ... the websites with the best info.. ALWAYS use the latin ... and then look for the annual growth rate ... this will tell you how much it should grow every season ... and then you just multiply by the decades .... i will do this one for you ... first baby blue spruce: https://duckduckgo.com/?t=ffcm&q=baby+blue+spruce&ia=web the 4th link there takes you to this if you click on the right link there: https://www.babybluespruce.com/baby-blue bullet point two says: The growth rate i.e: the rate of extension of the leader, is slower in the first two to three years and increases every year until at approx. three feet tall growth becomes similar to other blue spruce types soooo .. in 20 or thirsty years.. this will be a telephone pole ... it is ONLY a seed source cultivar for its blue color ... this is how i look for future potential .. note the latin name: https://duckduckgo.com/?t=ffsb&q=picea+pungens+baby+blue&iax=images&ia=images whass said all this ... now.. on the other hand.. there is a DWARF variation on the theme named baby blue eyes ... dwarf means it has a reduced annual growth rate.. so over the same decades.. it will end up smaller ... it appears to be a plant from the huge wholesaler monrovia.. note the first thing they mention.. is its slower growing ... that is why that name was mentioned above: https://www.monrovia.com/plant-catalog/plants/3634/baby-blue-eyes-spruce/ and here is future potential : https://duckduckgo.com/?q=picea+pungens+baby+blue+eyes+ACS&t=ffsb&iax=images&ia=images so thats how to research conifers .. and frankly.. and other NAMED plant hit send now before it gets ruined ken
