I have tried two times to grow salak from seeds, dunno the variety. First time the plants sprouted in winter and grew slow, come spring I took them out and for month or more they just sat with theyr first two leaves and did not do anything, it was not summer yet so it was maybe coolish for them to grow . Anyway I just ran out of patience and discarded them, they were fine in any matter.
Second time I sprouted the seeds again in winter ,maybe around january , then took them out with the rest of my tropicals around middle of april, in a unheated nylon greenhouse and for 2/3 nights there was frost . All other plants did well, the salaks started desicating in a few days and died in a week. Temps in the greenhouse got maybe to 0-1 C maybe lower . I knew I should have took them in ...
