Collecting tithonia seeds
Does anyone know how long it takes to mature tithonia seeds? I have been deadheading my plants to keep the flowers coming and I would like to know when to stop in order to give the seeds time to properly mature.
Also, as a sad footnote, my most beautiful plant snapped off right at the roots during a recent storm. It was about 7 feet high and very full. The ones that I had tied to the fence were okay. I guess those big wide leaves act like sails in a storm and catch the wind, and the stems are somewhat brittle. The stems look so tough I thought they could withstand anything, but apparently not.
