Care of Plant Cuttings After Treatment
Control the temperature
Temperature influences the speed to root cuttings. Higher temperature produces faster
effect. If possible keep the temperature between 65-70F. High temperature accelerates
fungus and bacterial growth above 70F. High temperature of the ambient air stimulates the
growth of shoots at the expense of roots. Keep the air temperature lower than the soil
temperature.
Control the light
After Rhizopon AA or Hortus IBA Water Soluble Salt
treatment and planting in media the cuttings need light and water.
For cuttings with leaves light is required for photo-synthesis to develop natural foods in
the form of carbohydrates. Provide shade on bright, hot days to avoid scalding the
cuttings. Cuttings without leaves do not require light for rooting; they depend upon
stored carbohydrates.
Control the humidity
 To
prevent the cuttings from dehydrating through the leaves and stems the cuttings are often
propagated under mist systems in controlled greenhouses or tunnels, in cutting trays
covered with plastic.
Control hardening off
After root initiation harden off slowly by reducing the temperature and humidity.
Frequently observe the growing environment and take action to assure that there are no
fungus, insects, pathogens, etc. After the cuttings are rooted control the environment to
bring the temperature and humidity to the ambient level.
Control the carbon dioxide
Maintain the carbon dioxide at about 1000 ppm.
Testing is essential
The condition of the cuttings or the rooted plant and the resultant rooting potency
varies from season to season. Check the results regularly. Adjust the dosage, timing and
method of application of Rhizopon AA or Hortus IBA Water
Soluble Salt rooting products and other propagation materials.
Fluctuation in the climate of the propagation area, varying light intensity, humidity,
wetness of the media, type of media, frequency of watering, fungus growth, insect
infestation, etc., will affect results. Carrying out a few tests will not take much time.
The tests will keep you up to date with results. Tests go along with your normal growing
operations and allow you to make timely corrective actions.
