Avocado trees, Persea Americana, require warm temperatures and plenty of sunlight to thrive and become productive. This hardy tree can survive in zones 10 and 11, which occur in small strips along Oregon's coast. The Mexican variety is best suited for the climate, as it tolerates temperatures as low 24 degrees Fahrenheit.
Starting Your Avocado Tree
Because avocado seeds require soil temperatures between 60 and 70 degrees Fahrenheit, they are often started inside first. Sprout your seed by partially submerging in water or by planting in porous soil.
Keep your avocado as an indoor potted plant if your Oregon address is outside of the recommended growing zones. Keep your tree near sun or good light in a pot with plenty of growing room. Fertilize every three weeks during the summer, and every six weeks in winter months.
Transplanting in Oregon
Spring is the best time to move your avocado to an outdoor location. For best results, choose a site that receives plenty of sun while offering at least 20 feet of space for its extensive root system. Feed your avocado a balanced fertilizer every three months.
