Garden Soil

Soil Type

Water: Marlberry thrives in humid understory environments and prefers evenly moist soil. It requires watering every 1-2 weeks, becoming moderately drought-tolerant once established. Favorable indoor humidity promotes healthy foliage, and maintaining moisture is essential for its year-round vitality as an evergreen.

Fertilize: To nourish marlberry, use balanced nutrition or high nitrogen fertilizers monthly in spring/summer, reducing in fall and pausing in winter. Avoid over-fertilization and direct contact with foliage. This regimen ensures optimal nutrient delivery, promoting vigorous growth and vibrant foliage for marlberry.

Pruning: Prune your marlberry in late winter or early spring to shape the plant. To prevent seed spreading, remove spent blooms to stop berry production.

Propagation: Marlberry is best propagated by sowing in a well-draining, moisture-retentive soil. Sow seeds shallowly and maintain consistent watering without waterlogging. A warm environment aids germination. Once seedlings are established, they can be transplanted to their permanent locations for growth.

Repotting: Marlberry is a dense, shade-loving shrub that needs repotting every 2-3 years. Early spring is the best time for this. Use a slightly larger pot, keep soil evenly moist, and provide indirect light to help marlberry adjust post-repotting.
