Container Garden Scale and Sooty Mold: Homemade Oil Remedy for Remote Location

Liz (near Guadalajara, Mexico): container garden in full sun. Scale on triangular palm, croton, others. Black granular coating on trunks/leaf backs. One croton dropped all leaves. Far from garden store. Asks: substitute oils (baby, olive, soy) for neem/dormant oil in homemade remedies?

Expert Homemade Recipe

Kathy: garlic-mineral oil spray.

Finely chop 10-15 garlic cloves
Soak in 1 pint mineral oil 24 hours
Strain, spray as-is or dilute with water + few drops soap

Practical Advice

Homemade remedies wash off (rain/sprinklers) → frequent reapplication
Neem absorbs into leaves for continuous protection
Neem orderable online, often cheaper than store

Key Insight

Remote gardening requires balancing homemade practicality with commercial product efficacy. Online ordering bridges the supply gap for systemic treatments like neem.
