Cymbidium Leaf Tip Browning: Salt Buildup, Flushing, and Outdoor Transition

Question:

Bought pink Cymbidium 2 weeks ago with 3 spikes (2 in full bloom). Third spike bloomed, but leaf tips turning brown. Room with skylight, no direct sun. Watered once 10 days ago. Cause?

Answer:

Hello Karen,

Browning tips likely existed at purchase—unnoticed amid blooms. Causes: high-salt water (sodium chloride), excess fertilizer, or both. Browning migrates down leaf over ~3 months, may kill leaf but not plant. Trim tips at angle if unsightly.

Minimize by double-watering monthly: water with plain water morning, wait 1–2 hours, water again. First dissolves salts; second flushes out. Run lots of water through drainage holes both times.

After blooms fade, move outdoors—Cymbidiums aren't houseplants. Keep out until nights <45°F. Outdoors: bright sun with midday semi-shade. Water more frequently (dries faster).
