Lucky bamboo with red roots
Ive had a lucky bamboo pyramid made up of several bamboos. Ive had this for just over a year but a few started to die.
The bamboos came is a square dish and the bottoms are covered with about 1" or silver gravel. I decided to take them out and put them in a glass vase with just water.
All of their roots are red. Anyone know what this is? Are they all dying?
I have never used fertiliser, just plain tapwater. Ive got a single curley bamboo in a vase with just water which has brown roots and had it for 4 years.
