The Westin Orange thrives in the ground across zones 9–11 and grows well in a large container anywhere, moved to shelter before frost in colder regions. Like most sweet oranges, it asks for sun, warmth, and steady drainage — give it those and it rewards you with juice-rich fruit for years.
Planting
- Choose full sun. Pick a spot with at least 8 hours of direct sunlight; sweeter, juicier fruit comes from the warmest, brightest location you can offer.
- Provide well-draining soil. Sweet oranges resent soggy roots. In the ground, amend dense or clay soil with compost; in a pot, use a quality citrus or cactus mix in a container with generous drainage holes.
- Set the depth carefully. Dig a hole as deep as the root ball and twice as wide. Position the tree so the top of the root ball sits slightly above grade — never bury the trunk or the graft union.
- Free the roots and backfill. Gently loosen any circling roots, fill in around them, and firm the soil to eliminate air pockets.
- Water in and mulch. Soak thoroughly after planting, then lay a 2–3 inch ring of mulch, pulled a few inches back from the trunk.
Care & maintenance
- Water: Keep the soil evenly moist but never waterlogged. Water deeply when the top inch or two dries out — roughly weekly in the ground, more often for containers in heat. Consistent moisture helps fruit fill with juice.
- Feed: Apply a citrus-specific fertilizer with micronutrients (nitrogen plus iron, zinc, and manganese) every 4–6 weeks from spring through summer, then taper off in fall and winter.
- Light & temperature: The Westin is happiest in warm conditions and is damaged by hard frost. In cold regions, grow it in a pot and bring it indoors to the brightest window before the first freeze.
- Prune: Shape lightly in late winter to early spring, removing dead, crossing, or weak branches and any suckers sprouting below the graft.
- Pollinate: Sweet oranges are self-fertile, so a single tree fruits on its own. Outdoors, bees handle the work; no second tree is required.
- Watch for pests: Inspect for aphids, scale, leafminers, and spider mites, and treat early with horticultural oil or insecticidal soap.
- Harvest: As a mid-to-late-season orange, fruit ripens later in the citrus season. Let it color fully and develop sweetness on the tree before picking, snipping or twisting fruit free with a short stem attached.
