I had the best info on baobabs that I was given But I have lost it now. Not sure were I got it.
I got gertmination of 95% in very hot weather middle of summer after very low germination in spring. By nipping into the seed casing with the tip of branch cutters. Totally peircing the casing, Soaking for 24 hours and then planting. Germination was in 4-5 days.
While waiting for leaf drop in winter the seedlings sufferd frost burn. This almost killed all of them.
The information I was given after this was that once the temp droped to below 5-10 deg celc (I forget the exact temp?) they should be protected. Not wait for leaf drop like I was. Then they can be bare rooted and kicked under the bed for winter
.
After the frost damage I left mine potted in soil and stuck them in the laundry cuboard. Darkness for about 4 months I guess untill the temps warmed up again.
The two that had survived the frost damage leafed out late spring to middle of summer.
Not much growth over the season but I put that to the frost damage. The apex o I now have them in a cuboard again for winter. I will see how they go next year.
I tried seeds in the manner I stated early spring and all failed to germinate. I will try again this summer when it is really hot.
I am growing the Australian Baobab it could be slightly different to ther African one?
