Hybrids among Aloe, Gasteria and Haworthia are creative. Mr. Lek suggests to select a female plant first then find a compatible male. Using a tiny brush, gently dab the tip of the bristle on male flower to collect the pollens, then on to the female. The pollination process should begin and pods are created.
Crossbreeding is easily hindered if not seeing successful pollination, or worse still not producing desirable offspring. You need to gain experience to guess and to be creative of how the offspring would look like as well.
Mr. Lek had successfully bred Haworthia koelmaniorum x Gasteria armstrongii. The lesson learned was to use H.Koel female flowers as its male had very limited number of pollens. After breeding with armstrongii the offspring bore many semblances of its parents, leaves, flowers, and seeds. Plus, the offspring was fertile.
With more experiences, he crossbred Haworthia koelmaniorum x Aloe and it gave him so many offsprings. He began the process by eliminating stamen from Aloe flower, so stamen brought over from H.Koel would have no competition to pollinate with Aloe since it can produce many more seeds than H.Koel.
