how to take cuttings from plants
Cuttings can be taken from many plants, but shrubs and perennials (tender
and hardy) are the normal choices.
Some plants, you just cannot grow from seed for practical purposes. Take
for instance, the very common Forsythia. For various reasons, Forsythias are
difficult to grow from seed, but they can easily be grown from cuttings – at
almost any time of the year.
Growing plants from cuttings is quite easy – once you are aware of the
several things that can go wrong. Don’t stop reading, for there are also
many things that go right when taking cuttings from plants.
One of the attractions of growing plants
from cuttings for the commercial grower is the fact that
each new plant, is identical to the parent from which the
cutting was taken. This is not always true of seed grown
plants. As an example, if you grow 10 apple seeds (pips)
into mature trees, then you will undoubtedly get ten
different trees – none of them resembling the parent
apple! More of that later!
Some of the plants which are best grown from cuttings are
shrubs, perennials, hardy herbs and alpine plants. Most of there are either
difficult to grow from seed, or at least take a long time to germinate and grow.
Most cuttings are rooted within a few weeks or so, and the new plant can be
persuaded to start growing as soon as you have put roots on it!
There are various types of cuttings to be taken. These include….
Softwood Stem Cuttings – Are as the name suggests, cuttings taken
from the very young side shoots or ends of new shoots. Typically, these are
taken early in the growing season, and maybe even from plants which have
been forced into growth with a bit of protection.
- Geranium or Pelargonium cuttings are normally Softwood, but can also be
semi ripe cuttings.
Fuchsia Cuttings as with Geranium
cuttings are normally softwood or semi ripe cuttings.
Dahlia Cuttings - You will
certainly need a heated Greenhouse and propagator.
Cuttings – Semi-ripe cuttings are those taken when the new shoots
have grown a little, and in the case of shrubs, have changed colour a little
bit from the new growth that is used for softwood cuttings. This type of
cutting is normally taken from outdoor plants after a couple months or so of
growth has taken place.
Ripe Cuttings – Ripe cuttings, or ripe wood
cuttings, are simply those taken either in late summer, or early autumn –
fall. Before the leaves start to go into their autumn colours.
Cuttings. Hardwood cuttings are taken in winter – fully dormant stem
growth is used, and the technique is rather different from other forms of
Root cuttings. Yes, some plants can actually be
grown from cuttings taken from their roots!
Leaf Stem Cuttings. There are a few plants that
can be grown from leaf cuttings. Some of the indoor plants such as African
Violets are grown this way. Some hardy plants can also be grown from leaf
Leaf Vein Cuttings. This is the normal method of
propagating Begonia Rex and a few other plants
Leaf Bud Cuttings. The leaf, together with a bud
at the base of the stem, are used for cuttings.
Hopefully the list of different cuttings has not put you off.
Maybe even, it has got you a bit curious. Good! Here we go!
Before you take the cuttings.
There are a few common reasons why cuttings fail to
root. The first thing to remember is the fact that when you take a shoot
from a plant, you are immediately depriving it of its moisture source.
Until you do your job properly, then it will have no roots through which
to absorb life giving water. The foliage will collapse, and the cutting
will invariably die. At ALL stages, you should do whatever you can to
avoid this moisture loss. Once the cutting is inserted in its compost,
the cutting and container should be made airtight with a polythene
cover. This can simply be a clear plastic bag, or a sheet of polythene
for larger projects.
The best time for collecting cuttings, is in the early morning,
whilst the parent plant is still turgid – full of water. Later in the
day – if it is hot – the shoots may well be depleted of moisture.
Cuttings can be taken later in the day, but extra care will be needed to
conserve – and replace – any moisture. Popping your cutting material
into a plastic bag, and keeping it out of the sun is a good start. Splash
a few drops of water into the polythene bag - this will help to keep a
good humidity level.
Cleanliness is important. Your cuttings knife should be clean. Various
virus diseases can be spread by using a dirty un-cared for knife. The
virus can be spread to each cutting that you take. This is sometimes a
problem if you take many cuttings of the same plant types. For instance,
enthusiast chrysanthemum growers can take many hundreds of cuttings of
their plants – a virus on one plant can soon be spread to each of the
cuttings via the knife.
A few cuttings of lavender or whatever will not normally be a problem.
After you take the Cuttings.
The cutting should be prepared, and inserted into
cuttings compost right after taking it from the plant. Cover them with a
plastic cover – either clear or milky white – as soon as it is inserted.
It is essential to do this . Moisture loss for the cutting is a big
problem. Keep the new cuttings container out of direct sunshine.
Compost for Cuttings
Some cuttings can be rooted, simply by placing them in
a glass of water. Done that? Mostly, they are inserted into proper
cuttings mix compost – easily made up by yourself!
My favourite all-purpose mix is simply some peat based general purpose
compost, with an added 25% of sharp sand. Washed sharp sand is best
used, as builder’s sand often has high lime content. Alternatively, you
can use either perlite or vermiculite instead of the sand. If using
vermiculite, then go 50/50 with the compost. The added sand or
vermiculite, simply ‘opens’ up the compost a little to allow free
drainage, and also allows air to get into the compost.
Some cuttings can simply be rooted in moistened sand, but the new roots
are normally brittle, and easily break off on potting up. Nevertheless,
a sand bed outdoors for autumn cuttings of shrubs, is a great way to put
roots on shoots!
Hormone powder or liquid gel.
As well as having ingredients to assist the cutting to
grow roots, most hormone powders or gels will also have a fungicide.
This is useful to prevent the first attack of any fungi when taking the
cutting. Never use more than is suggested on the package, otherwise it
will have a detrimental effect of the rooting of your cutting. It can
even rot the base of the cutting if you use too much.
