I'd like to try again (had one somewhat success) next spring to grow some hostas from seed. Do I have to leave the seed pods on the plant to dry or can I cut the canes off and let them dry? I won't be here when they start to break open.

Hosta seeds generally take about 6 weeks from blooming to ripen and probably a bit longer than that before the pods burst open on their own.

Will you be gone for a significant length of time around when they will be ripening? If so, it may be difficult. You could try cutting them early and ripening them in sugar water (about 1 tsp sugar to a cup of water), but you need to change the water regularly - about once a week. Or you could try to affix a net bag around the seed stalk to catch any seeds that are dispersed while you are away. But if you can be there about 6 weeks after flowering, just cut the scapes and cut the pods off. Place in labelled PAPER envelopes and allow to dry for a few weeks.

To know when a particular variety flowers, take pictures and date and label them.

Good luck.

Oh, if it's six weeks I might be okay. Thanks.
