Hi,
Whether you want to water, lucky bamboos the whole year is all depend on
what you want to gain and want you want to avoid. For example, if you want to
achieve academic excellence you put a glass of water at your south sector the
whole year. If you are afraid of gossip you might want to remove the water
during the lunar month 7 when Star 3 arrive at the South.
You must always remember that you want to have the 1,4 combination. It
doesn't matter if the bamboos is in water or soil. But I personnaly prefer
planting them in water as it look nicer plus water produces wood. It wil
further enhance star 1 or 4 and at the same time we have the combination of 1
and 4.
For Star 9, use soil instead of water.
Regards,
