Feed soil-grown lucky bamboo monthly during the growing season. Feed water-grown plants every other month. These intervals belong to separate culture modes.
How to fertilize lucky bamboo
Choose the culture first. Soil-grown Dracaena sanderiana gets a monthly growing-season interval, while water-grown plants use every-other-month feeding at one-quarter of the recommended rate.
Check for active growth
When to fertilize
Routine feeding is described from April through October, while the soil schedule is tied to active growth. Dates vary with climate and room, so do not assume winter feeding continues.
Follow the product label
Fertilizer type and dose
Use houseplant fertilizer for soil culture and liquid houseplant fertilizer for water culture. NC State describes a weak liquid fertilizer for the exact plant. This does not endorse a brand or true bamboo.
For water-grown Dracaena sanderiana, use one-quarter of the recommended fertilizer rate every other month. Clemson gives no soil dilution rate, so the product label and soil culture must remain separate.
Inspect a stressed plant before feeding
When not to fertilize
Overfeeding can damage roots. If yellowing or stem rot appears, check water, drainage and culture before adding fertilizer. A yellow leaf or weak stem does not prove nutrient deficiency.
