WANT to know the best way to germinate karaka seeds. I've collected
quite a few seeds from the ground under trees at our local beach
over the last two years. I dry them, then plant them in spring,
but many of them don't grow. Can you help?
seed is mature when the flesh has turned from green to orange, which
is usually around late summer, but may vary, depending on your area
Don't dry the seed,
but clean as much of the flesh off as you can, which is mimicking
what happens when the berry is eaten by the native wood pigeon.
Sow the cleaned seeds straight away in a freedraining mix, burying
them about 2cm deep. It doesn't matter which way you lay them, but
on their sides is probably how they would land on the ground naturally.
Put the pots or trays of seeds in a sheltered spot, indoors or out,
protected from frost over winter. Keep them moist, but not constantly
soaking wet, and wait patiently.
You may have to protect
them from hungry rats and mice over winter, but by next summer many
of the seeds should have germinated.
