Identifying "Anon" (Cuban Fruit) and Persian Lime Growing Tips

Trudy's Cuban in-laws call a fruit "Anon." It's grapefruit-sized, green, with segmented white flesh and black seeds. She also wants tips on growing Persian lime.

The Mystery Fruit: Annona squamosa (Sugar Apple / Custard Apple)

"Anon" almost certainly comes from the genus Annona. Annona squamosa matches your description perfectly:

• Tropical, grown in Africa, Asia, Americas
• Pale green, fragrant flowers on old wood
• Large fruit with fused segments, tough green/brown skin
• White, custard-like pulp with many brown/black seeds

Other Annona species exist (A. cherimola cherimoya, A. reticulata custard apple), but A. squamosa is the most common "sugar apple" in Caribbean gardens.

Persian Lime (Citrus × latifolia) Basics

• Sun: Full sun (8+ hours) for best fruit.
• Soil: Well-drained, slightly acidic (pH 6–6.5).
• Water: Deep, infrequent — let top 5 cm dry between waterings.
• Fertilizer: Citrus-specific formula with micronutrients (especially iron, zinc, manganese) 3×/year: early spring, early summer, early fall.
• Cold: Hardy to about -3 °C (27 °F) briefly. In marginal zones, grow in pots and protect.
• Pruning: Light, after harvest. Remove crossing branches, water sprouts, thorns.

If you're in a frost-free area, plant in ground. Otherwise, a large pot on wheels lets you move it to shelter.
