TAG THE CROSS... just below the flower. These tags were rectangular, but were cut to size for easier attachment. You can find them at most office supply stores. To ensure durabiliy use a paint pen. Label with date and parents. POD PARENT (female, the flower that receives the pollen) goes first X POLLEN PARENT (male, the flower the pollen came from) last. As in the photo above... Managua is the pod parent, Batik is the pollen parent.
RECORD KEEPING: The amount of records you choose to keep about your crosses is totally up to you. However... it's essential that you keep track of POD X POLLEN parents, not only when you tag the cross, but when you plant the seeds, and as the seedlings develop. Most hybridizers want accurate records of the parents, and supplying this info makes the offspring more desirable to some. It also helps you retain a professional reputation as a hybridizer. As the seedlings begin to bloom, you can give them seedling names, such as 06-16a. (06) designating the year it germinated, or the year the cross was made. (16) for the 16th cross made that year, and (a) for the first seedling to bloom from that cross.
SUGGESTION... Attach the tag before you pollinate. If you are working on a plant with numerous blooms open, you may reach down to pick up your tag, and forget which flower you just pollinated.
