4-8 weeksTiny columnar sprouts with minimal spination, appearing as small green columns
Keep soil lightly moist (not wet), provide bright indirect light, maintain warmth (70-80°F), protect from fungal issues with good airflow
Juvenile
1-2 yearsGrowing columnar stems with developing spines, reaching 12-36 inches tall
Gradually transition to full sun, reduce watering frequency as plant matures, apply balanced fertilizer sparingly during growing season
Established Growth
1-2 yearsMultiple thick columnar stems with prominent spines, plant 3-8 feet tall
Minimal watering except during drought stress, fertilize lightly in spring, prune only to remove dead/diseased material
Flowering
Several weeks of sporadic bloomsLarge white tubular flowers (3-4 inches long) bloom along upper stem sides at night, sweetly scented
Peak bloom in late spring/early summer, flowers last one night, ensure adequate sunlight for blooming, minimal intervention needed
Fruiting
2-3 months from flowering to harvestSmall round green fruits develop where flowers were, ripening to yellow or reddish tones with edible sweet pulp
Fruits are self-compatible but cross-pollination increases yield, protect developing fruit from excessive moisture, harvest when ripe

Fun Facts
- 🌱 Trichocereus macrogonus is a night bloomer; its large white flowers open in the evening and are pollinated primarily by bats, a remarkable adaptation for arid desert environments.
- 🌱 Despite its common name 'Cardón,' this plant is distinct from the true cardón (Pachycereus pringlei) of Baja California, though both are iconic desert species.
- 🌱 The plant can live for 100+ years in the wild and produce hundreds of fruits annually once mature, making it a reliable food source in harsh desert regions where other crops fail.
