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
of rain.
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
seedlings.
Thanks and regards
Giorgio
