黑骨芒

想請教一下,

呢排棵o野葉邊開始變黃,想請問下最有可能有咩問題?

我擺在室內,有散射光,無風直吹,早晚向葉噴水,每晚淋一次水(試過早晚都淋,不過可能真係太濕,一淋就直出,所以就變成每晚一次)

而家生大o左,不過底部同埋最出果o的葉仔仍然係黃同枯lor

我之前都種過黑骨芒 同佢作戰咗2個月
2盆仔先後瓜晒.......
淋水又唔係, 唔淋又唔得, 不過啲葉又係係咁黃

我認為多數是泥太濕引致爛根, 空氣濕度低
我看見有人將它放在戶外斜坡腳騎樓底
雖然有風, 但越長越大

我棵O野而家半生不死.....

high humidity + a bit cooler temperature --> success

low humidity + hot weather + lots of sunlight +over-watering + damp mix --> 死

其實係放空內O既(廁所有窗),我早晚都係噴下水,夜晚就淋水LOR,植料係買返來果時跟的,應該係PEAT MOSS來的~
咁我而家需要點做呢?

you have to be cautious about temperature in toilet and see whether there could be direct sunlight some time which could harm the plant ~

Actually if new leaves are OK and growth is still vigorous, it's still OK ~ just remove those old leaves and beware of over-watering

I think the coolest place is my toilet, no need to change the substrate?

我都有棵用1/3石仔料+3/2種av的peat moss (內含珍珠岩),全peat moss好似太濕,而且係坐水碟種,無水至加.

Peat moss takes a bit too long to dry out. Just observe how long the mix takes to dry out first. If it takes more than a week, you had better change to some others that are more porous.

Peat moss mix with perlite is something that you can try as it dries out more quickly and less easy to cause problem of root rot.

The tray method Beasy is using is only applicable when you put course rocks underneath which fills up 1/4 to 1/3 of space of the pot so that mix is always above water level. Otherwise there will be high chance of root rot ~

temperature comes first, humidity second ~

Same as highland nepenthes

我都有種呢隻嘢, 每年約呢個時候, 盆芒都好似你哋的情況咁, 啲葉開始枯黃乾謝, 新標出唻的芽又係乾/燶/黑/開唔到葉, 但係過一排後, 佢自己又會回復青春, 我唔知點解會咁, 唯有當佢係週期性休眠咁看待囉! 已經過咗三年, 佢都休眠咗三次
