Growing Night-Blooming Jasmine Indoors: Light, Water, and Pest Control

Growing Night-Blooming Jasmine Indoors: Light, Water, and Pest Control

Night‑blooming jasmine (Cestrum nocturnum) in Calgary (Zone 3) faces short winter days and dry indoor air. Your plant's brown leaf tips, bud drop, and spider mites all stem from root‑zone issues.

Root Problems Cause Leaf Burn and Bud Drop

Overwatering, a pot that's too large, excess fertilizer (bone meal, bloom boosters), or hard water can all damage roots. Damaged roots can't supply water and nutrients, causing tip burn and bud abortion.

Spider Mite Treatment

Spray the entire plant—especially leaf undersides—with a strong stream of water, then follow with a soapy‑water spray (liquid dish soap). Repeat weekly until no mites are seen.

Cultural Corrections

• Pot size: Use a container just large enough for the root ball. The plant flowers best when pot‑bound.
• Light: Provide as much direct sun as possible (south window). Some direct sun increases flowering.
• Water: Let the top inch dry between waterings. Flush excess salts monthly.
• Fertilizer: Stop forcing blooms with bone meal and high‑phosphorus feeds. Fertilize lightly only during active growth.

Patience

Night‑blooming jasmine flowers when it's ready—often after a year or more of good care. Focus on healthy foliage; blooms will follow.
