Deciduous Trees and Shrubs
What are Deciduous Trees and Shrubs?
Deciduous trees and shrubs are plants that lose their leaves at the end of each growing season; usually during the winter, but can also occur during a dry season in warm climates. In Project BudBurst, we group deciduous trees and shrubs together, however, there are significant differences. Deciduous trees are generally defined as woody, self-supporting perennial plant that have a single main stem and grow to more than 20 feet tall.Deciduous shrubs are woody, perennial plants that are smaller than trees (less than 20 feet) and usually have several stems.
Deciduous Trees and Shrubs to Observe
Click on a plant name to the right to access printable Regular or Single Report forms to take with you when you observe your plant. These reporting forms describe the leafing, flowering, and fruiting events to look for.
If the plant you'd like to monitor is not on the list, download our Regular Report or Single Report forms for Deciduous Trees and Shrubs which describe the leafing, flowering, and fruiting events to look for.
Two Ways to Observe Deciduous Trees and Shrubs
The phases you monitor for Deciduous Trees and Shrubs will depend upon whether you are observing your plant using Single Reports or Regular Reports.
Regular Reports: Using Regular Report forms, you track your plant (or plants) throughout a season, recording the dates when key leafing, flowering and fruiting events occur (event-based reporting). The Regular Report phenophases for Deciduous Trees and Shrubs are: Bud Burst, First Leaf, All Leaves Unfolded, First Flower, Full Flower, First Ripe Fruit, Full Fruiting, 50% Color, 50% Leaf Fall.
Single Reports: Using Single Report forms, you select a phase that best describes the leafing, flowering, or fruiting phase that your plant is currently in (ie. Flowers-middle or Flowers-early) on the day you happen to see it (status-based reporting). The Single Report phenophases for Deciduous Trees and Shrubs are: Leaves Unfolding (None), Leaves Unfolding (Early), Leaves Unfolding (Middle), Leaves Unfolding (Late), Leaves Changing Color (None), Leaves Changing Color (Early), Leaves Changing Color (Middle), Leaves Changing Color (Late), Leaves Dropping (None), Leaves Dropping (Early), Leaves Dropping (Middle), Leaves Dropping (Late), Flowers (None), Flowers (Early), Flowers (Middle), Flowers (Late), Fruit (None), Fruit (Early), Fruit (Middle), Fruit (Late).
