Re: Root Cuttings

Dear Duncan,
Your questions are very interesting.

There are several ways to propagate plants (SOME methods follow)

(1) seeds 
    (a) may not produce true to the parent plant especially if the parent is
a hydrid
    (b) some plants do not produce seed (ie: seedless fruit and veggies) 
    (c) some plants take many years to produce fruit
    (d) some seeds are difficult to germinate
    (d) in general, if the above are NOT true then you are better to use seed!
CLONAL:
(clonal means that the parent plant looks like the new plant)
(2) division, generally successful for clonal propagation where applicable
to the plant variety
(3) stooling, generally successful for clonal propagation where applicable
to the plant variety
(4) grafting, generally successful for clonal propagation where applicable
to the plant variety
(5) micro propagation, difficult to do in an average propagation setting;
many plants have not yet had success. Some varieties do not produce true to
parent.
(6) bulbs and tubors, generally successful for clonal propagation where
applicable to the plant variety

(7) propagation from cuttings: many plants can be produced to exactly
duplicate the parent plant. Generally easy to do if you select the proper
type of cuttings and treat them as appropriate. Juvenile cuttings produce
roots easier. Cutting should be taken at the time appropriate for the plant
variety. Generally take cuttings from the current year growth. A wide range
of plant varieties are suitable

The following is extracted from the basic information concerning Rhizopon AA
rooting hormones which are supplied by our company. 
You can order from your local hort supplier. 
Your supplier can order from the master distributor: V-J Growers Supply
800-327-5422 or you can order from V-J direct. 

Propagation of plants by the rooting of cuttings is not a mystery. 
Take cuttings at the proper time from carefully selected stock plants. 
Use a successful rooting method with the optimum concentration of Rhizopon
AA rooting hormones. 
Take care of the cuttings. 
It is important to do testing and keep records to produce the best results
and successful repeat rooting.

Select the appropriate Rhizopon product. Use the following guides. 
Use the lowest concentration of Rhizopon AA to do the job. 
For herbaceous and tender woody cuttings use Rhizopon AA #1 or #2 dry powder
or Rhizopon AA Water Soluble Tablets to make a solution. 
For woody cuttings use Rhizopon AA #2 or #3 dry powder or Rhizopon AA Water
Soluble Tablets to make a solution.

To root cuttings the method of treatment is your choice! 
Use either the dry-dip powder method or a liquid application method. 
Rhizopon AA is integrated family of dry powder and liquid applied rooting
hormone products.

The time of the year may change the method and concentration. 
Cuttings of the same plant variety may root better using Rhizopon AA by
powder or liquid. 
Greenwood cuttings from one plant may root better with liquid treatment. 
Later in the growing season more woody cuttings from the same plant may root
better with powder treatment.

Rhizopon AA is  productive.  
When treating many cuttings, such as chrysanthemums, use low concentrations
of Rhizopon AA Water Soluble Tablets by the total immerse or spray drip-down
methods. These methods use minimum labor.

Rhizopon AA is economical. 
When treating many different types of cuttings that require different
hormone concentrations the Rhizopon AA #1, #2 and #3 dry powers have an
advantage. Switching from one concentration to another is easy.

Rhizopon AA is cost effective. 

When treating many small production lots Rhizopon AA #1, #2 and #3 dry
powders do not need special preparation. They are ready to use.

Rhizopon AA Water Soluble Tablets can be made into concentrations for any
use. Rhizopon AA Water Soluble Tablets are made into solutions by the user
ranging from very dilute to extremely concentrated. With a diverse selection
of plant varieties to root, Rhizopon AA Water Soluble Tablets may be the one
product to use for all of them.

Rhizopon AA Water Soluble Tablets are used by various methods to root plant
cuttings.  When treating many cuttings total immerse dip them in a basket
then plant. Many cuttings are treated by spray drip-down; first plant then
spray the solution onto the cuttings until there is drip down. By quick dip
the basal end of the cuttings are immersed in the solution then planted.

RHIZOPON AA #1, #2 AND #3 dry powder rooting hormones are used to propagate
plants from cutting by the Dry-Dip Method. They are ready to use in three
concentrations. 

Rhizopon  AA #1 is the lowest concentration. 
Use to root cuttings of house, foliage, tropical and hardy ornamental
plants. Herbaceous, leaf, greenwood and softwood cuttings.

Rhizopon AA #2 is the intermediate concentration.
Use to root cuttings of house, foliage, tropical and hardy ornamental
plants. Herbaceous, greenwood, softwood and hardwood cuttings.

Rhizopon AA #3 is the highest concentration.
Use to root cuttings of more difficult to root woody ornamental plants.
Softwood & hardwood cuttings.

Propagate Plants from Cuttings Using the Dry Dip Method. 
Take plant cuttings, usually stem, root or leaf cuttings. 
Woody cuttings are usually wounded by making a 3/4" notch at the basal end. 
Herbaceous cuttings are not wounded. 
Dip the basal end of the plant cuttings into the appropriate Rhizopon AA #1,
#2 or #3 dry powder rooting hormone. 
Plant the cuttings immediately after treating and take care of them.

RHIZOPON AA WATER SOLUBLE TABLETS plant growth regulator rooting hormones
are used to propagate plants from cuttings and to improve the growth of
rooted plants. Users make their own solutions and apply to cutting and
plants by dip, soil soak, or spray.
Propagate Plants from Cuttings Using Solutions. 
Take plant cuttings, usually stem, root or leaf cuttings. 
Woody cuttings are usually wounded by making a 3/4" notch at the basal end.
Herbaceous cuttings are not wounded. 
Make up a Rhizopon Water Soluble Tablet solution using the appropriate
concentration. Using the Spray Drip-Down Method first plant then treat. 
Using the Immersion, Quick Dip, or the Total Immerse Method first treat then
plant. 
Take care of the cuttings.

Immersion Method. 
Immerse the basal end of cuttings approximately 1" in the solution for 4-12
hours. Plant the cuttings immediately.
Herbaceous and woody cuttings: 1-3 tab/l. water.

Quick Dip Method. 
Immerse the basal end of cuttings approximately 1" in the solution for a few
seconds. Plant the cuttings immediately.
Herbaceous cuttings, tropical plants, house plants, roses, etc: 
3-10 tab/l. water. 
Chrysanthemum: 4-10 tab/l. water. 
Softwood cuttings: 20 tab/l. 
Hardwood cuttings: 40 tab/l. 
Difficult to root hardwood cuttings: 100-400 tab/l.

Total Immerse Method. 
Immerse the whole cuttings in the solution for a few seconds. Plant the
cuttings. 
Herbaceous cuttings, chrysanthemum, plumbago, ivy, clematis, delphinium,
lavender, ficus, potted rose bushes, etc.: 1-5 tab/l. water. 
Softwood cuttings, hydrangea, pieris, hedera, etc: 1-6 tab/l. water. 
Hardwood cuttings, conifers, etc: 4-10 tab/l. water.

Spray Drip Down Method. 
Plant the cuttings. Spray the  solution onto the leaves and stems until drip
down. 
Herbaceous cuttings, chrysanthemum, begonia, dieffenbachia, heath, hibiscus,
etc: 1-5 tab/l. water.
