Hi Jim, I wrote to your address a mail with some pictures, may be that mail was lost ?
For the seeds dry, I must say that at the end of June we had here a
very high temperature, over 35 °/37° despite of some storms with a =lot
I saw that the seeds of Dracontium and Consanguineum, started and
packed on 30 June, took a week to show the first germs, now with the
same seeds started and packed on July 15, with 10° less outside, they took 11 days to start germination.
In that hot period I saw the seeds stopping to rippen, some plants also who started ( very late ) coming out from soil didn't flower and
those plants were very slow in growth.
I am now growing Flavum abb. seedlings, Dracontium ( from a plant I
bought in Rome), and Consanguineum, with pots with akadama, ( like
Turface ) and they seem fine, i water them once a day, at night
together with the bonsai I have in shadow.
Early to say if Osmocote is working well or not, but till now
everything is OK, some pictures available of potted seeds and
Thanks and regards
