Growing Avocado from Seed Indoors in New England

Avocados are tropical trees needing specific conditions replicated indoors:

Environment

• Temp: 55–75°F, 10°F night drop beneficial.
• Soil: 50% potting soil / 50% sand. Fast drainage. No standing water.
• Light: Major challenge. South window, drapes open, no blinds. PLUS 2–4 tube fluorescent fixture (1 cool + 1 warm white tube) on chains, 1 foot above, raised as trees grow.

New England winters make light the limiting factor. Supplemental fluorescent is non-negotiable for healthy growth.
