To maintain artificial outdoor shrubs, wash them regularly to get rid of dust, dirt and oil buildup. During hot months with minimal rainfall, frequently wash the plants by hosing them down. Adjust the shape of bent leaves and stems as necessary. Ask the store where you purchased the artificial plants for particular maintenance instructions, as different manufacturers use varying types of materials.
Use clean water and mild soap when washing artificial plants. Remove accumulated dust on small plants by using a handheld vacuum cleaner. When caring for artificial flowering plants, air-dry the plants, and place them in plastic bags for storage until the next landscaping season.
Large artificial plants require vacuuming once every two weeks. When storing large plants, air-dry them, wrap heavy plastic around the plants, and arrange them in groups near a wall for protection against harsh weather conditions.
Artificial plants are made of sturdy materials with UV-protectant coating to last long under sun exposure. Artificial barberry shrub branches are typically available without pots, allowing you to arrange the branches based on your preferred sizes and shapes. Artificial asparagus ferns are often potted plants with single branches that you can arrange for personalization. Artificial Taxus Yew shrubs are also pre-potted plants that stand around 3 feet high and 2 feet wide. Boxwoods are common options for topiary and hedgerows.
