Soil and Container Requirements for Dwarf Citrus in Cold Climates

Potting Mix

Use a light, well-draining citrus/cactus mix or amend standard potting soil with 30% perlite and 10% compost. Line the container bottom with 2 inches of gravel.

Container vs. Ground

In Indiana (zone 5–6), dwarf Washington navel orange MUST stay in a container. It cannot survive ground planting. Choose the largest pot manageable (20+ gallons ideal).

Indoor Winter Care

• South-facing window, 6+ hours sun.
• Mist leaves to deter spider mites.
• Water when top 2 inches dry; never let sit in water.
• Fertilize monthly with citrus-specific formula.

Summer Outdoors

Move outside after frost danger passes; acclimate gradually. Full sun, daily watering in heat.
