Clonex Rooting Hormone Gels                     

Purpose:  puts roots on your plant  cuttings

Clonex comes  in  3 strengths which  are colour coded  for easy  identification.

Indole butyric acid (also known as IBA) is a plant hormone that is responsible for root initiation and growth and  is the active ingredient  in  Clonex.

Clonex Green    active ingredient 1.5 g/L IBA for herbaceous and softwood cuttings

Clonex Purple  active ingredient 3.0 g/L IBA for semi-hardwood cuttings

Clonex Red       active ingredient 8.0 g/L IBA for hardwood cuttings

 Types of Cuttings

Herbaceous  cuttings from non woody  herbaceous  plants

Softwood cuttings from material taken from soft and flexible young wood from current years growth

Semi-hardwood  cuttings from  partially  mature  wood  from the current years growth

Hardwood  cuttings from mature wood  from previous years growth that does not bend  easily.    ·

Benefits of Clonex:   

Increased  strike rate from the gel holding the active  ingredient   against the plant tissue

Higher safety levels for workers since they are not breathing in talc and hormones

The gel seals the cut and stops air embolisms in the plants vascular tissue preventing  wilting  of the cutting

How far does a bottle of Clonex go?

This depends on the diameter of the cutting and the depth to which the cutting  is dipped, but  the grower should  expect several thousand  cuttings  per  litre of Clonex

Which Clonex?

Generally the type of cutting, that is either softwood/semi hardwood etc  determines which  Clonex to  use. If there is callusing but no root formation this indicates the hormone level is too high and a lower hormone  concentration  should be used.

Stock plants  (mother plants)  need  to be:

 Disease free Nutritionally sound

Turgid,  not water stressed

If flowering, remove flowers and  buds

Stem cuttings are the most common type of cutting

 Usually 4 to 6 inches long

Use current or last year’s growth Terminal parts of stem best.

Long shoots can give several cuttings

Keep cuttings cool and  moist  until  they are stuck

If delayed cutting material can be stored in fridge in a plastic bag Remove  leaves from bottom  I /3 to Yi of stem

Cut leaves of large leafed  species in  half

Pour Clonex into a separate container for dipping

Do nor pour unused Clonex back into original container Dip cuttings to I cm up the stem

45 degree angle cut is best Stick and maintain  humidity

Post Cutting Care

 Humidity should be maintained at a high level Air changes  should  be done regularly

Moisture  level in medium  needs to be maintained

Plant food needs to be supplied to the cuttings when roots first form Light  levels should be satisfactory  for  photosynthesis

Rooting  Media  should  have these properties:

 Sufficient pore space to contain air.

Be free draining, but still hold enough water for the cutting. The medium  should be  disease free.

The medium  should contain  all plant mineral nutrients essential for  growth.
