Care Guide
Ardisia Japonica is a low-maintenance plant that is easy to care for. Here are some tips:
- Water: Marlberry prefers moist soil but can tolerate short periods of drought. Water regularly during the growing season, and reduce watering in the winter.
- Fertilization: Feed with a slow-release fertilizer once a year in the spring.
- Soil: Marlberry prefers well-draining soil that is rich in organic matter. If the soil is too heavy, add some sand or perlite to improve drainage.
- Sunlight: Marlberry prefers partial shade to full shade. Direct sunlight can scorch the leaves.
- Hardiness Zones: Marlberry is hardy in USDA zones 7-10. It can tolerate temperatures as low as 20 degrees Fahrenheit.
Common Pests & Diseases
The marlberry is relatively pest and disease resistant, but it can be susceptible to the following:
- Scale insects: These tiny insects attach to the leaves and stems and suck sap from the plant, causing yellowing and stunted growth. Treat with insecticidal soap or neem oil.
- Leaf spot: This fungal disease causes brown spots on the leaves and can lead to defoliation. Remove infected leaves and treat with a fungicide.
- Root rot: This is caused by overwatering or poor drainage and can lead to wilting and death of the plant. Improve drainage and avoid overwatering.
