Begonias - Sowing Seeds & Propagating Leaves, Stems and Sections

January 12, 2005

Following an introduction to the benefits of plants and how much we depend upon them, the 24-member class was divided into five 5-member teams.  Using pre-determined team names (oxygen, temperature, water, soil and light) each student drew a team name.  With the assistance of Master Gardeners, the students sowed Dragon Wing Begonia seeds in flats and took cuttings from a Dragon Wing Begonia growing in our Demonstration and Trial Garden.  The students prepared stem cuttings, leaf cuttings and leaf sections and placed them atop a combination of Pro-Mix and vermiculite in clear plastic salad containers which will serve as terrariums for this project.

As the semester progresses, students will chart the changes in the seeds and the cuttings.  They will evaluate which method of multiplying plants is most economical, which is fastest, which is most labor intensive, etc.  Through this page you will be able to read the student's own  observations and summaries of goals, successes and failures.

During the introduction to why we grow plants and how they benefit us, the class compared seeds and learned they come in a variety of shapes and sizes.  They also learned the parts of a seed and compared monocots and dicots.

     

Each of these lessons will better prepare the students to participate in an upcoming project in which each team will select a planting goal and manipulate water, light, temperature, fertilizer, etc. in order to achieve that goal.

 
January 21, 2005 This journal entry was provided by the water team:

We observed a bad thing had happened to our begonias. The propagated begonias started to mold. Each group had to cut off the molded sections of the leaves and replace any toothpicks that were covered in the fungus. To hopefully help eliminate the mold, we also opened the terrariums so that the begonias and soil would stop absorbing so much moisture therefore causing the plants to die. 

January 27, 2005 Moisture has been a challenge in this experiment.  In preparing the plastic terrariums, probably too much water was added to the Pro-Mix.  This resulted in the growth of mold.  On January 20, students removed diseased sections of the leaf cuttings.  After allowing the terrariums to remain open a few days, now we are experiencing a situation in which the potting medium is not retaining sufficient moisture.  Students are misting the soil on a daily basis which indicates the containers are not sufficiently airtight to allow condensation to form.
February 10, 2005 Today's review of the begonia project indicates some success.  Several leaf cuttings remain green, but maintaining good soil contact is an ongoing challenge.  At least one stem cutting has produced a bud.  Five (5) seedlings have emerged from the 22 begonia seeds that were sown.  Today we took additional stem cuttings from rex begonia and coleus as well as a mystery plant which the students will have to identify.  Today's cuttings were placed in plastic storage bags (baggies) filled with two cups of moistened Pro-Mix. 
This Mystery Plant was brought to class by Master Gardener Brenda Johnson.  Students took stem cuttings from the plant and placed them in baggies filled with moist Pro-Mix to create a good growing environment.  The class is working to identify the plant during the coming week.  Students must also define "epiphyte" for an upcoming lesson.
