Phalaenopsis Leaf Growth Without Blooms: Light, Fertilizer, and Cool Trigger

5 Phals, Leaves Only = Excess Nitrogen or Missing Cool Period

Sphagnum likely decomposed (repot in bark). New leaves smaller than old = root issue. Black leaf tips = hard water + overfertilizing.

Rebloom Trigger

• Repot all in fresh bark mix.
• Use bottled water if very hard.
• Feed ¼ strength balanced.
• Autumn: 55°F nights ×2–3 weeks.
• Watch for green spike between leaves.

Light Shelf Plan

Grow lights help Chicago winters. Cold damage on window plants = move back.
