During this field trial the Zantedeschia’s where reviewed by there appearace, average lenght, number of flowers and buds, and stem length.


The zantedechia’s are longer when treated with Stimuter liquid ( especially treatments 3,4 and 5) compared to the untreated object. The quantity of flower buds and flowers is also higher in the treated objects. In one treatment with Stimuter, there appeared to be 66% more flowers present in the treated object compared to the untreated object. Also the length of the roots was longer in the treated object, mainly Stimuter liquid + Stimuter granular. The results are shown in table 2 and 3.
