Water control is something very important for using moss as you said, moss is highly absorbing ~
Imagine you now have a ball of sphagnum moss of 50g and another ball of moss of 100g.
Then you wrap roots of 2 phalaenopsis of similar size with the 2 balls of moss and put the root mass with moss into 2 pots of the same size respectively.
Water these 2 pots thoroughly and let water drains for some time until there is no more water coming out ~
Now, which pot hold more water ??
Of course the answer is the pot with less sphagnum moss as air space inside the pot with more moss is less and it can hold less water ~
That is why I suggested you to "squeeze" moss a bit tighter in a pot so that the pot can hold less water to prevent root rot. Although how "tight" the moss should be is judged by experience, you can still do it properly following a simple rule of "not too loose and not too tight" ~
Everytime you water, it has to be thorough ~ Water only when moss turn a bit dry ~ You can tell by observing top of the substrate and the watering time comes when top moss turn white ~ never keep the moss wet all the time as it will retard root growth ~
There is no absolute time of watering but the right time varies from condition to condition. Dryer and sunny place will have a shorter duration between each watering and you can water less frequently in shaded growing area instead ~ |
