Appearance
Elaeagnaceae plants exhibit a wide range of growth habits, sizes, and leaf shapes. Most species have simple, alternate leaves that are green or silvery-grey in color. The flowers are often small and inconspicuous, but some species produce showy, fragrant blooms that are white, yellow, or pink in color.

Care Guide
Elaeagnaceae plants are generally easy to care for and adaptable to a wide range of growing conditions. Here are some basic guidelines for their care:
- Water: Water regularly during the growing season, but avoid waterlogging the soil.
- Fertilization: Fertilize with a balanced, slow-release fertilizer in spring and mid-summer.
- Soil: Plant in well-draining, fertile soil that is slightly acidic to neutral in pH.
- Sunlight: Most species prefer full sun to partial shade, but some can tolerate shade.
- Hardiness Zones: Check the hardiness zone of the species you are growing and plant accordingly.
Common Pests & Diseases
Elaeagnaceae plants are generally resistant to pests and diseases, but they can occasionally be affected by some common problems:
- Rust: This fungus causes yellow or orange spots on the leaves and stems. It can be prevented by providing good air circulation and avoiding overhead watering.
- Spider mites: These tiny pests can cause yellowing and stippling of the leaves. They can be controlled with insecticidal soap or neem oil.
- Aphids: These sap-sucking insects can cause distortion and discoloration of the leaves. They can be controlled with insecticidal soap.

Many species are well adapted to poor soils and drought conditions, and they are often used for land reclamation and erosion control. Some species are also used in traditional medicine and as a source of food and oil.
