Propagate Plants at Home

Save money (The average home garden spends many thousands of pounds -and that is just the initial set up. Over the years plants die and need replacing; and without realizing it, an absolute fortune can go into buying plants. 
 
Growing your own healthy plants from next to nothing can be a facinating and rewarding hobby. If you love plant collecting it can help save on the cost of buying plants. It can also provide presents you can give to freinds and relatives; or donate to community projects.

 

Another Alternative:

Our principal has written two books that can help you learn about plant propagation.

We've also produced a comprehensive video that can be purchased as a DVD to learn all about propagation.

Lesson Structure

There are 10 lessons in this course:

  1. Methods of propagation - overview
  2. Propagating Structures & Equipment
  3. Propagating Materials
  4. Seed Propagation
  5. Propagation by Cuttings
  6. Miscellaneous Propagating Techniques - Division, layering, tissue culture.

How are Plants Propagated?

Broadly, there are two ways of propagating plants - asexually and sexually.

Asexual propagation involves growing a new plant from some part (e.g. leaf, stem and root) of an existing plant This is also known as vegetative propagation because it uses the 'vegetative growth' of the 'parent plant to produce the 'daughter' plant 

Sexual propagation involves fertilisation of female plant parts by male parts to produce seeds or spores from which new plants are grownThere are many different reasons why we might choose to propagate plants one way rather than another:

-the availability of propagating material (can you get plenty of seed or cuttings?)

-ease of propagation (which technique is the easiest?)

-speed of propagation (which technique produces new plants quickest?)

-importance of maintaining true characteristics (plants grown from seed can differ from their 'parent plant in terms of scent, colour, shape, size etc. Asexually propagated plants do not vary in this way).

SEXUAL PROPAGATION

Following are the most important considerations when attempting to germinate seed or spores.

Provision of a Correct Environment

Requirements here can vary considerably from plant to plant. Drainage and structure of your propagating mix. amount of watering, temperature and light (or dark) can be important for success. For most seed (but not all), an ideal mix would be 75% coarse propagating sand plus 25% of either peat moss or vermiculite. Most seed is best germinated under glass.

Pre-germination Treatments

While some seeds will germinate immediately in the correct temperature and moisture conditions, others have to be treated in some way first 

 
ASEXUAL PROPAGATION

Separation

In this situation, plants naturally produce completely new offspring at the base of existing specimens. Separation simply involves breaking these clumps apart; examples are daffodil, tulip, gladioli, hyacinth and crocus.

Division

Some plants grow in such a way that one individual plant can be cut into sections and each section will grow as a new plant; examples are phlox. canna iris, dahlia and potato.

Layering

Layering involves promoting the growth of roots on a stem while it is still attached to the parent plant Once these roots establish, that section of the plant can be cutaway and planted as a new plant The main advantage of layering is that it does not risk the loss of propagating material if the operation is unsuccessful.

Budding and Grafting

These techniques involve attaching a part of one plant onto another plant in such a way that the two will grow together. The end result of budding or grafting is a plant which has one variety for its root system and a different variety for its top. This is a valuable technique in many situations, e.g. growing a variety that is susceptible to root disease on a resistant root system.

Cuttings

Cutting propagation is by far the most commonly used asexual technique. It involves inserting a section of a plant in a soil mix to promote leaf and root growth.

There are four types of cutting:

STEM CUTTINGS, which use a section of stem with most of the leaves removed.

ROOT CUTTINGS, which use a section of the root

LEAF CUTTINGS, which use either a whole leaf or section of leaf.

LEAF BUD CUTTINGS, which use one leaf attached to a very small section

of stem with a bud.
