Pitcherless Nepenthes DeRoose Alata: Light Acclimation Is Key

Healthy Leaves, No Pitchers

A two-year-old Nepenthes 'DeRoose Alata' grows well in a west window but produced only one pitcher last fall. After moving outdoors for more light, still no pitchers. The grower suspects fertilizer in the repotting mix.

Diagnosis

Fertilizer in soil is not a problem—Nepenthes tolerate it better than other carnivores. The issue is light: this plant needs at least 3 hours of direct sun to pitcher. In a north window, it grew leaves but no pitchers. After moving to a sunnier spot, it took a month to start pitchering. Outdoors, place it where it gets 1–2 hours of morning sun, then dappled light. Don't move it once positioned—stability encourages pitcher development.
