Growing Avocado from Seed: From Sprout to Fruiting Tree

Avocado seeds sprout readily but developing a healthy, productive tree requires attention to light, temperature, and pruning—especially outside tropical zones.

Identifying Root vs. Shoot

The broad end of the seed produces the shoot (stem/leaves); the pointed end produces the root. If a sprout emerges from the broad end, that's the top. Plant with pointed end down, sprout just above soil line.

Critical Growing Requirements

• Light: Intense, direct light essential. South/east windows minimum; supplemental fluorescent lighting (12-14 hrs) often needed in northern latitudes
• Temperature: Above 50°F always; 65-85°F optimal
• Water: Consistent moisture, excellent drainage—no "wet feet"
• Pruning: Pinch terminal bud at 12-18 inches to force branching; repeat to develop bushy form

Seasonal Management

Summer outdoors (above 50°F nights) promotes robust growth. Winter indoors: bright light, reduced water, no fertilizer. Expect 5-7 years to fruiting; seedling fruit quality variable. Grafted trees fruit in 2-3 years with known quality.
