How To
The following suggestions for the use of Rhizopon AA and Hortus IBA Water Soluble Salts are based on the outcome of tests and experiments carried out by international testing stations, research centers, scientific publications and Rhizopon and Hortus USA's own research.
Testing is essential. Suitable test rates should be used on a small portion of the crop before doing extensive treatment. Select the rate which provides the desired effect. The actual conditions at your facility may not be the same as the place were the data was obtained. You might find highly successful results if you vary the concentrations somewhat from the listed amount.

BASAL APPLICATION |
DRY DIP METHOD |
Dry Dip Powder.
Dip basal end in rooting powder
then stick.
(Powders stay on cuttings a long
time) |
RHIZOPON AA #1, #2 & #3
Dry Powder Rooting Hormones.
Use dry; not to make rooting
solutions |
BASAL QUICK DIP METHOD |
Rooting Solution.
Dip basal end in rooting solution
then stick. |
HORTUS IBA WATER
SOLUBLE SALTS
Use to make rooting solutions |
BASAL LONG SOAK
METHOD |
Rooting Solution.
Dip basal end of cuttings in rooting
solution about 12 to 24 hours
(nominal) then stick. |
FOLIAR
APPLICATION |
Spray Drip Down |
Rooting Solution.
Stick then spray leaves of cuttings
with rooting solution until the
solution drips down. |
TOTAL IMMERSE METHOD |
Rooting Solution.
Totally immerse cuttings in rooting
solution then stick. |

Converting Rates
The rates for rooting solutions in this website and on the Hortus IBA Water Soluble Salts label are listed as ppm IBA (parts per million IBA). Some books on plant propagation list ppm IBA for their suggested IBA basal quick dip rates. The rate chart below gives the weight of Salts required make ppm water soluble IBA rooting solutions.
Hortus IBA Water Soluble Salts rooting solutions can be used in every case where IBA, K-IBA or premix rooting solutions are used. |
