VITAMIN Bi 
(Vitamin Bi, Hydrochloride. Thiamin Chloride) 
For Use in the Treatment of Cuttings, Transplantings, 
and Growing Plants in General 
Vitamin Bi is one of the necessary factors in the normal growth of plants, one of its functions 
being to increase or stimulate root growth. (Vitamin B, is not a fertilizer and will not take the place 
of fertilizers.) At first one was led to assume that the formation and accumulation of the vitamins in 
plants, such as fruits and vegetables, was for the benefit of mankind, but it is now known that they 
are also just as necessary to the normal functions of plant life as in human life. 
The Vitamin Bi used is a synthetic preparation that contains only Vitamin Bi. By using any 
other source such as extracts from rice polishings or yeast there is some danger of bacterial contami¬ 
nation as well as the introduction of traces of compounds which may inhibit or retard plant growth, 
hence doing more harm than good. 
Some of the uses of Vitamin Bi are (1) treatment of cuttings, (2) when transplanting any 
plant, shrub or tree (3) for plants that are slow growing, and those that are not growing properly 
(due to poor root system). 
Some plants are very poor producers of Vitamin Bi (such as Camellias), or have inadequate root 
systems, therefore being below their normal growth rate, they will respond to application of Vitamin Bi. 
Feeding plants Vitamin Bi is a very simple procedure and offers many advantages to the users. 
It is added to the water and applied in an ordinary watering either by ditch, basin, sprinkling, or 
otherwise. In general Vitamin Bi should not be added to the water more than once a week. 
In the treatment of cuttings it can be applied in two ways, either by standing the base of the 
cuttings in a solution of Vitamin Bi for 24 hours (see Rooting of Cuttings by G. C. Warner and 
F. W. Went, mail 26c to The Plant Culture Publishing Co., 876 Roxbury Drive, Pasadena) or by 
sprinkling heavily enough to get to the base of cuttings once a week. 
In transplanting any plant even from a seedling to a full grown tree, if watered in with 
Vitamin Bi it will do away with a large portion of setback and loss due to root injury, and adjustment 
to the new environment. 
In the case of slow growing plants and those going back instead of ahead, often the results 
will be marked. However, a certain number of plants will not respond to Vitamin Bi as it is only one 
of the substances necessary for plant growth. In some cases you will see a difference after a few 
days, while in other cases such as bent grass, it may take several weeks for the difference to become 
apparent, as the root system is built up before there is a change in top growth. 
A partial list of plants benefitted by feeding Vitamin Bi; avocados. Bougainvillaea, carob tree, 
Camellias, Cosmos, ferns. Gardenias, grass, lemons, orchids and Strelitzia. 
To make the solution for treatment of cuttings or watering plants already rooted, put a spot 
of Vitamin Bi (powder) about the size of a head of a pin (1 mg), on the end of tooth pick in 
marked vial, fill to mark with cool water, use one drop of this solution for each gallon of water re¬ 
quired. Keep solution of the marked vial in refrigerator. The powder will keep indefinitely.
