Two "species" of Morus nigra mulberry?


Hi Livinginawe,

did the seeds finally sprout?

I am getting a little worried. Mine are in the soil now for exactly 1 month. Out of 48 seeds only 1 sprouted. That was 2 days ago, so I hope I just have to wait a little longer. I didn’t use bottom heat, maybe that is a factor too.

If yours did finally sprout that would ease my mind a bit.


Yes…I have had about a dozen sprout so far, but only five healthy plants. Even though I stratified the seeds for three months they still seemed to want the varying cool/hot cycles of spring to sprout, as it took about a month before I had the first one sprout. Nearly two months later a dozen have sprouted…one more just yesterday…so be patient. I didn’t use bottom heat or anything, just have the pots in my greenhouse that is usually left opened up and exposed.


Thank you, thats encouraging. My trays are still indoors. I will move them outside (into my greenhouse) next week since we finally start to get warmer temperatures more consistently.


The new generation:



My nigra seedlings had survived outdoor this winter (most of them):



Even this one - about one inch high!

The dead one:


Very nice,

from the first batch of seeds started (at least trying to) in march only 2 sprouted until now. Both withered and dried back after some days. Those young seedlings seem to be very fragile. Are there any recommended measures to keep the little seedlings alive?


That’s good news. What was your lowest winter temperature.


They are very delicate. I would avoid exposing them to rain or direct sun. Rain will smother them. You will always end up losing some, no matter what. For a plant capable of living several hundred years, I’m surprised childhood years are so tricky…


I personally prefer Norman Deno’s paper towel method for germinating the seeds (chapter 3, page 13):

(Norman Deno is Professor of Chemistry, passed away at age 96 in 2017):

So, after 3 monts cold stratification, I moved the moist packets OVER THE fridge, near backside, where the warm air is present. Checked every 2-3 days and sowed only the seeds that are germinated. The % of germination is
low indeed.


The lowest temperature this winter was -18 C. But this was for short time and there was 40 cm snow cover.
For comparison: The small asian persimmon seedlings from 2017 had survived under the snow too. Two years old feijoa seedlings are death above snow line and push green below.


Thank you @chriso and @pileta,

yesterday the next 2 seedlings sprouted. They are really taking their time… Its now 4 out of 48, not exactly an overwhelming successrate, but I do hope some more will follow.

Now the quest is to keep them alive. As I said above the first 2 died shortly after sprouting.
