Cereus forbesii SEEDS

When it comes to cultivation, especially from seeds, patience is key. Cereus species prefer well-draining soil and should not be overwatered. They thrive in full sun, requiring temperatures between 70 to 95 ºF (21 to 35 ºC) from spring to fall, and cooler temperatures down to 50 ºF (10 ºC) in winter. For those in colder climates, bringing potted plants indoors during winter is advisable. Seeds should be sown on the surface of a well-draining mix, lightly pressed down, and kept moist until germination occurs, which typically takes between 14-28 days at an optimal temperature of 70 to 80 °F (21 to 26.6 °C). While Cereus can also be propagated by cuttings, starting from seeds can be especially rewarding, offering the full experience of watching these magnificent plants develop from the very beginning​.

For general care, water your Cereus thoroughly during the active growth period in spring and fall, allowing the soil to dry out before watering again. Reduce watering frequency in fall and keep the cactus dry during winter dormancy. Fertilize regularly during the growing season with a balanced, water-soluble fertilizer diluted to 1/4 strength. Young Cereus cacti should be repotted annually in early spring, but mature plants can be repotted less frequently, only when they outgrow their pots​​.

Given the right conditions and care, Cereus forbesii can be a stunning addition to any cactus collection, offering both beauty and the satisfaction of successful cultivation from seeds.
