Learn About Trees for Rehabilitation
Trees for Rehabilitation course online. Distance Learning – Home Study. Learn to plant, care for trees and conduct tree surgery in degraded landscapes.
Trees really matter! They provide animal life with the oxygen needed to survive, accumulate carbon in their wood, strengthen the soil around their roots, give shelter to wildlife and supply humans with building materials for shelter and tools.
Trees are also good for our well-being because, among other health benefits, they filter out dust and pollutants and so help to protect the environment.
For all of these reasons, tree health is very important to future generations and many governments recognise the dangers continued deforestation, plus pests and diseases pose to their long term survival.
Many councils in the UK have Tree Management Plans in place and the Department for Environment Food & Affairs has a published Tree Health Management Plan, written in cooperation with The Forestry Commission.
This Trees for Rehabilitation course builds an understanding of environmental systems and the rehabilitation of degraded landscapes, so will give you the skills needed to manage the health of trees.
Learn about seed collection, storage and germination, propagation, plant selection, establishment techniques, controlling pest & disease after planting.
The Trees For Rehabilitation course concludes with a lesson on Environmental Assessment and how to Conduct an Environmental Audit, plus implementing land rehabilitation management program by determining land objectives and determining a program for replanting.

The importance of trees to land management cannot be overstated. Often in the past they have been seen as competing for valuable land space and felled indiscriminately. Over clearing of trees can lead to salinity problems and numerous forms of erosion and land slips.
As we have become more familiar with their vital role in ecological processes, retention and selective planting of trees has been widely acknowledged, in improving farm viability and ultimately production.
This course develops an understanding of environmental systems and the rehabilitation of degraded landscapes. You learn about seed collection, storage and germination, propagation, plant selection, establishment techniques, controlling pest and disease after planting.
HOW CUTTINGS WORK
Asexual Propagation A cutting is a piece of vegetative growth (non-sexual ‑ not the flower or fruit) which is detached from a plant and treated in a way so as to stimulate it to grow roots, stems and leaves; hence producing another new plant.
Cutting propagation is most commonly used for shrubs, indoor plants and many herbaceous perennials. It is the most common method of asexual reproduction used by horticulturalists. As a general rule, it is rarely used to propagate most types of trees.
When a plant is grown from a cutting it is genetically identical to the parent plant. This is not necessarily so when plants are grown from seed. Cuttings are the most widely used technique for reproducing “true to type” plants. This ensures that the unique characteristics of the parent plant are passed on to the progeny.
Cuttings can often be used to propagate plants that:
- Don’t produce viable seed, or produce seed at irregular times,
- Have seed that is difficult to germinate
- Have seed that is difficult to collect, for example, plants that have seed pods that burst open dispersing the seeds widely
- Produce their seed at a time when seed cannot be collected, or collection would require a further trip to the area (often very difficult for remote areas), or can only be collected with difficulty (e.g. plants whose seed matures during wet seasons when access may be limited).
Cuttings can be useful as they may avoid the problem of juvenility in the newly propagated plants. Most plants grown from seeds go through a juvenile stage, in which flowering, and hence seed production does not occur.
Some plants may take 5, 10 or even more years before they commence flowering. Once a plant has flowered, plants propagated from that plant by cuttings will avoid the juvenile stage and flower early, often within months of the cutting having struck.
Many plants also have undesirable growth forms when they are young. These include very vigorousgrowth, thorniness, or unattractive foliage or form. By taking cuttings from adult plants these undesirable characteristics can be avoided. In some cases the juvenile form of a plant may have characteristics that are more desirable than those of the adult form.
You may take cuttings from plants growing in gardens, pots, parks or in the wild; and you may successfully produce new plants from cuttings taken from any source; however, you will always get much better results if you carefully choose your source of cuttings.
- If you know the cultivar name of the plant, you can be more certain of how to propagate it, and be confident of the characteristics that will be demonstrated by the new plants.
- If you take cuttings from healthy plants; they are more likely to develop roots faster, and produce healthier plants quicker.
Why Cuttings? Despite all the difficulties that can be experienced with various techniques to propagate a plant, the cutting technique still remains one of the easiest and cost effective techniques to produce a number of new plants, whether that is for commercial or domestic production.
Cuttings are easy, time effective and cheap; the rewards in watching a plant produce roots and develop into a new plant encourages them to propagate even more plants, and share them with friends etc. Commercial production nurseries know the benefits of the cutting technique.
Their profit and existence relies upon using the right technique for the right plant. Improving their techniques can increase production and hence increase profit. Growing plants by cuttings can be a very rewarding exercise, and for commercial propagators may be the most economically viable method for many plants.
How to Propagate a Cutting
Most cuttings are pieces of stem, often with some leaves left at the top of the stem.
Some plants can be grown from cuttings of other tissue (eg. a piece of leaf, or section of root, or even part of a bulb, with no stem at all). Cuttings are usually planted into a mix of materials such as sand, peat moss, perlite, rockwool or vermiculite. Part of the tissue is usually below the surface of the mix, and some exposed above the surface.
The cuttings should then be kept moist and other conditions such as light, temperature, humidity and hygiene should be kept appropriate to the requirements of the variety of plant being grown.
Other things that can be done to enhance development of the cutting will either speed the rate of growth or improve the percentage of cuttings that succeed. Chemical hormones may be applied to stimulate the formation of either roots, or foliage/shoot growth.
Pesticides or disinfectants may be used to prevent diseases or pests. Heating may be used to warm the root zone (ie. bottom heat), to encourage faster growth of roots; or periodic misting of the foliage to cool the top of the plant, or prevent dehydration of the foliage.
If you want to get the best results from your cutting propagation, you really need to pay attention to selecting the appropriate technique for the time of year, and type of plant you are growing. Different types of plant tissues have varying abilities to
Assessment is based on a combination of completing all assignments and sitting for a final short one and a half hour exam, in your own location.
If you don’t cope well with exams then you may elect to undertake a project instead. This is a popular option.
In addition, most modules have a Set Task at the end of each lesson placed before the assignment. This is an opportunity to undertake practical work to help you acquire knowledge and skills and practical experience. This ADL feature is an added bonus not found at most online schools. Set Tasks are not required for assessment.
Some courses also have optional Self-Tests which are available on our online learning platform. These are not available by correspondence or by USB, and do not form part of your overall grade.
