Double lucky pyramid bamboo is a type of lucky bamboo. The plant consists of two layers of lucky bamboo, stacked together and secured with a band or tie. The bamboo generally rests upright in a bowl full of rocks and water. Caring for double lucky pyramid bamboo is fairly simple. The most important thing to consider when caring for lucky bamboo is the water source. Additives in most tap water can harm the bamboo, so it's best to either use bottled water or make distilled water for the plant.
Fill a small container with tap water and allow it to sit out uncovered for about 24 hours. This allows harmful fluoride and chlorine to dissipate, making the water safe for the plant to drink.
Slide the double lucky pyramid bamboo out of its bowl and gently lay it down on a folded paper towel.
Pour the contents of the bowl, including the rocks, into a fine mesh strainer. Rinse the rocks with cold water until they're clean and no longer feel slimy. Hold the bowl under warm running water and clean it with a small pot scrubber to remove mineral deposits. Do not use dish soap to clean the bowl.
Hold the double lucky pyramid bamboo upright in the bowl and pour the clean rocks in around it. Arrange the rocks around the base of the bamboo, so that it is supported upright. Top off the bowl with the distilled water and place the bamboo in a spot that gets bright, indirect light. Repeat this lucky bamboo care process once a week.
Fertilize the double lucky pyramid bamboo once a month. Mix one part fertilizer to 10 parts distilled water and water the plant with the mixture. Be careful not to make the fertilizer solution any stronger than that. It can burn the roots.
