IDENTIFY AND GROW DECIDUOUS TREE SPECIES.
- Learn about the main types of deciduous trees.
- Develop your knowledge of deciduous trees.
- Home study can save you time and money.
- Increase your confidence and knowledge.
- Making the proper decisions will help you save money, so pick the right plants.
- Horticulturists and those wishing to use deciduous trees to build more energy-efficient homes should take this course.
In addition to being attractive, deciduous trees are crucial for giving both winter light and summer shade.
In both hemispheres, deciduous trees are commonly planted. They are crucial to forestry and amenity horticulture. For horticulturists, landscapers, arborists, nursery workers, gardeners, park managers, or anyone else concerned with the selection, propagation, care, maintenance, or harvesting of deciduous trees, this course is a fantastic foundational study.
These lovely garden additions have a wide range of applications, and this thorough course imparts specialised expertise. The course will give you specialised knowledge of these trees, giving you access to a wealth of resources for your own garden or the gardens of others.

Aims
- Refresh your basic understanding of plant identification and culture as necessary to develop your knowledge specifically related to deciduous trees.
- Become knowledgeable about the Acer genus’ categorization, identification, and culture of plants.
- Become knowledgeable about the genus Betula’s categorization, identification, and culture of plants.
- Learn about the culture, categorization, and identification of plants of the genus Fraxinus.
- Learn about the culture, categorization, and identification of plants of the genus Quercus.
- Learn about the culture, categorization, and identification of plants in the genus Prunus.
- Review a number of other notable deciduous tree genera that were not previously covered in this course.
- Arrange the planting of a variety of various deciduous tree cultivars that are well suited for a given location.
WHAT CAUSES THE AUTUMN COLOR CHANGE IN FOLIAGE?
Deciduous plants lose their leaves in the fall or early winter, and during the colder months of the year, they are completely or partially leafless. With this adaptability, the plant is better able to withstand adverse circumstances (such as extreme cold).
-
They go through a senescence phase before the leaves fall.
-
Leaf cells gradually die during a phase known as senescence..
During the senescence stage, tissue at the leaf base gradually dies until it completely separates from the stem and leaf (At this point there is nothing left to hold the leaf to the stem; so it detaches and drops to the ground).
The amount of chlorophyll in the leaf, which gives it its typical green colour, decreases as senescence takes place. Chlorophyll is actually just one of several pigments that are typically present in leaves, but because it is frequently the strongest pigment, if a plant is healthy, the majority of its leaves will typically seem green.
Additional kinds of pigment compounds that are frequently discovered in leaves include:
-
Anthocyanins –Reds, Blues and Purples
-
Carotenoids –Yellows and Oranges
In the fall, carotenoids often also break down quickly, although anthrocyanins do so considerably more slowly.
Even when just 40% of the typical amounts of carotenoids and chlorophyll are present, anthrocyanin levels can frequently still be close to 100% normal.
Excess sugars in the leaves are converted chemically into anthocyanins, especially in the presence of intense light. Given this, the concentration of anthrocyanins will be higher if the plant had been actively making sugars through photosynthesis over the summer and had a lot of sunny autumn days (if weather is frequently overcast and dull in late summer and autumn; the production of anthrocyanins is decreased).
As a result, if the weather quickly shifts from warm to cool, the leaf sugar stays high and anthrocyanin levels increase. If the weather were to change slowly, these pigment levels might not be as high.
The colours of the autumn foliage will often be more vibrant when anthrocyanin levels are high.
What Can You Expect From This Course?
This is a relatively specialised course that isn’t offered very frequently or certainly not to the level of learning depth you’ll find here. After graduating, you’ll have a fairly special understanding of deciduous trees and be able to compare and recognise many more genera and species than the majority of horticulture or arboriculture experts.
You will be able to spot opportunities that others don’t, which will improve your ability to accomplish your job and make you more appealing to clients and employers.
Using this course to:
- doing a better job
- giving you an edge over competitors in this field.
