Ipomea Questions for the MG Experts:

What factors influence the bloom time (sexual maturity)
Photo period? Day length? Temperature?
Any methods to force them into bloom?
I notice some vines will die-off after setting seed?
Is this like tomatoes that can be bred for determinate/indeterminate?
What is best fertilizer? 20-20-20 or 10-20-10?
Are there any pruning methods to encourage/discourage branching?
Will different species hybridize?
