Avocado Plant Care: Water, Soil, Light, and Pruning

Fix the Basics

• Pot size: 5-gallon max for 3–4 ft trees.
• Soil: Quality potting mix with fertilizer and moisture control—not garden topsoil.
• Light: Gradually acclimate to full sun for thicker growth and larger leaves.
• Water: Water deeply only when top soil is dry; use room-temperature water.
• Fertilizer: Wait until spring; use balanced 10-10-10 or 20-20-20 once yearly.

Pruning for Structure

Avocados become spindly without pruning. Every 2 months in spring/summer, cut back ~3 inches to just above a leaf node. Stop in fall/winter. This encourages branching and a stronger trunk.

Winter Care

• Bright light (greenhouse or grow light).
• No drafts or heat vents.
• Reduce watering.

Long-Term Reality

These become 40–50 ft trees. Plan for eventual size or commit to ongoing hard pruning.
