Neem Oil Smell Alternatives: Horticultural Oil or Perfume

Neem meal in watering spikes won't work—neem acts on leaf surfaces, not systemically. Mask neem oil smell with perfume, or spray outdoors until odor fades. Alternative: all-seasons horticultural oil (e.g., Bonide). Avoid hort oil in extreme heat, freezing, high humidity, fall, within 30 days of sulfur, or on sensitive plants. Homemade: 1 quart water, 1 tsp dish soap, 1 tsp baby oil (smothers insects).
