Flowering Plum Tree 'Gulihongmei' (骨里红梅) Bare Root

The flowers of Gulihongmei are deep red, pink, and emit a slight fragrance. They bloom once a year, typically between March and May, offering good ornamental value. To ensure abundant and bright blooms, here's how to nurture Gulihongmei:

Temperature: Gulihongmei prefers warmth but can tolerate temperatures ranging from 61°F (16℃) to 73°F (23℃) during the growth period. In winter, it can withstand temperatures as low as -10 degrees Celsius. To promote bud formation, move the plant indoors to a temperature of 32°F (0℃) to 41°F (5℃) after the flowers fall. After New Year's Day, move it indoors to a temperature of 41°F (5℃) to 50°F (10℃).

Sunlight: Gulihongmei thrives in full sunlight. During summer, provide shade to prevent overheating and diseases. In winter and spring, ensure the plant receives sufficient sunlight for bud formation and bright blooms.

Humidity: Keep the soil moist but well-drained during the growth period to prevent water accumulation and root rot. In autumn, water less as the plant absorbs less water. After New Year's Day, maintain slightly moist soil and spray water on the branches.

Fertilization: Use decomposed manure at the bottom of the flower pot to promote vigorous growth. Apply compound fertilizer during flower bud differentiation in June and decomposed manure after leaf fall in autumn. Before blooming, apply a thin layer of phosphorus and potassium fertilizer, and during flowering, use decomposed cake fertilizer.

Pruning: Prune about 20 days after blooming, focusing on cross, upright, and diseased branches to encourage flourishing.

In summary, Gulihongmei, also known as cinnabar plum, has red woody branches and brightly colored flowers, making it highly ornamental. Maintain it by moving indoors during winter, ensuring proper sunlight, humidity, and fertilization, and pruning after flowering for abundant and bright blooms.
