I sowed some Drosera seeds in March and only a few germinated. Then in May, I sowed more seeds in the same pot. None germinated.
Last month, I moved the pot to receive more direct sunlight as the only plant in the pot of several hundreds seeds, a D. hartmeyerorum, is mature and I would like to get it to flower. Still, no further germination from the heat..I .thought it may help break down some inhibitors.
However, after I poured some used GA3 solution (from soaking Byblis seeds overnight) onto the pot surface a week ago...VOILA!!!! The seedlings are popping up!
Anyone uses GA3 on Drosera seeds on a regular basis? The seeds I sowed could be at least a year or more old.
