malus bacatta seeds germinating

Oak Summit Nursery · Southern Manitoba

malus bacatta seeds germinating, showing a careful method if you’re monitoring germination rates. Usually I’ll stratify and plant them into a community pot then prick out the germinating seeds. But I have a few seed lots of these and I want to check the germination rate, so planting them as they germinate. Note these went 38 days in cold strat, and germination started 1 day after warming up, each day I’m getting 10-20 from the bag start. Sometimes longer stratification will make all of the seeds germinate at the same time. Sometimes I wait a few weeks and determine I didn’t strat them long enough and the seeds go back in the fridge for another cycle. Sometimes I soak the ungerminated seeds with a ga-3 spray and see if it helps. by far the easiest way is to plant outside in the fall, but this gives me something to do over the winter and some trees do well with a head start. #seedstarting #appleseed
