Water Propagation Rot on spider plant
What's Happening
Spider plant pups root easily in water, but stagnant water or contaminated containers promote bacterial growth that causes cut tissue to rot instead of root. The thick, fleshy base of spider plant pups is susceptible to anaerobic bacterial infection when submerged in water with low oxygen or high organic matter. This appears as mushy, translucent tissue at the base and foul odor.
How to Fix It
- 1
Use clean glass container—sterilize with diluted bleach or hydrogen peroxide before use
- 2
Change water every 3-5 days to maintain oxygen levels
- 3
Use room-temperature filtered or distilled water (not tap water with chlorine)
- 4
If rot appears: cut above rotted section, let callus dry 24 hours, restart in fresh water
- 5
Root in bright indirect light—avoid dark locations that slow rooting
How to Prevent It
Spider plants root readily in water, but require clean conditions. Never use water that has been sitting for weeks. Avoid overfilling container—submerge only the basal 0.5 inch of pup stem, not the entire base.
