- Fertilization: Magnoliopsida plants benefit from regular fertilization with a balanced fertilizer.
- Soil: Magnoliopsida plants prefer well-draining soil that is rich in organic matter.
- Sunlight: Most Magnoliopsida plants prefer full sun to partial shade, but there are some species that prefer shade.
- Hardiness Zones: Magnoliopsida plants have a wide range of hardiness zones, from zone 1 to zone 13.
Common Pests & Diseases
