Height of the tree or plant measured from the pot or root ball. For example, 125-150 cm.
Trunk circumference of a tree measured at 1 meter height from the ground. For example, 10-12 cm.
Pot sizes are always indicated as, for example, P9 or C3.
The letter C stands for container, and the number behind it indicates the volume in liters.
C5 thus means a pot with a volume of 5 liters.
C1 = 1 liter content
C2 = 2 liters content
C3 = 3 liters content
C5 = 5 liters content
C6 = 6 liters content
The letter P stands for pot size, and the number behind it indicates the size in centimeters.
So, a P9 pot is 9x9 cm wide.
P7 = 7x7 cm large and has a volume of 0.4 liters
P9 = 9x9 cm large and has a volume of 0.7 liters
The most common form of a tree, a single almost straight trunk with a crown on top.
A tree that has been grafted by means of budding. In this process, a specific cultivar is set on the stem of a seedling, creating a different species. A well-known example of this is the ball catalpa. The stem height from where the grafting is placed is often indicated in this case.
A tree with a single trunk that branches from below.
A tree that forms multiple stems not higher than 50 cm above the ground. Multi-stemmed trees are created by pruning a single stem. These tree forms are often used as standalone eye-catchers in a garden or park.
