Vegetative Growth

1-2 years

Light shaping pruning to encourage branching; maintain consistent watering; fertilize with balanced citrus fertilizer every 4-6 weeks during growing season

3

Flowering

3-6 weeks per flush

Fragrant white blossoms appear in clusters, typically in spring

Harvest Tips

Ophir fruits mature in winter/early spring (December-April in Northern Hemisphere). Fruits develop deep orange color when ripe and develop sweetness as they age on the tree. Pick by twisting gently or cutting with pruning shears, leaving 1-inch stem. Fruits can stay on tree for several weeks after ripening without deterioration, allowing selective harvesting. Expect 25-50 fruits per mature dwarf tree.
