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.

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


nigra-2

nigra-4

Even this one - about one inch high!
nigra-5

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?


#187

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


#188

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.
