How to fertilize a sago palm

01
When to fertilize
Feed during active growth or a new leaf flush. Growth is slow and comes in bursts, so watch the plant rather than the calendar.
Follow active growth rather than a calendar. Use outdoor spring, summer, and fall schedules only for outdoor plants. Indoors, pause feeding while the plant is not growing.
02
Fertilizer type and dose
Use a palm fertilizer that contains manganese. Do not give a high-nitrogen fertilizer at a guessed dose.
03
When not to fertilize
Manganese deficiency can be associated with yellow or spotted new growth, while too much fertilizer can injure cycads. Inspect the newest flush and root-zone history before changing feed.
