Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://balconygardenpicks.com/how-we-research#our-score Neem oil is a plant-derived oil used as a natural pesticide and fungicide, effective against common pests like aphids, spider mites, and whiteflies as well as powdery mildew. For balcony gardeners, whose plants sit close to seating and shared air, it is a gentler alternative to harsh chemicals for keeping container plants healthy. When choosing a product, decide between concentrated cold-pressed oil you dilute yourself, which is more economical, and ready-to-use sprays that are simpler for beginners. Look for cold-pressed, high-azadirachtin oil for potency, clear mixing instructions, and organic certification if that matters to you. A product that emulsifies well in water sprays more evenly and clogs less. ## Picks ### 1.
