At least seven gingers live here. Five are ornamental. Two are culinary. None have yet died back as they should for winter.

Now that it is time to divide them, I do not know what to do with their intact foliage. For this white butterfly ginger from Forest Garden, I divided the rhizomes and installed them into the landscape with their healthy foliage still attached. I do not want to cut it back until it succumbs to frost. I suppose that it can remain as long as it is healthy. It is likely promoting healthier secondary growth. Because none of the gingers are crowded yet, it should not be difficult to selectively groom out older growth as new growth develops. I doubt that older foliage absolutely must be pruned away during winter. If it were that important, the rhizomes would shed it naturally, with or without frost.

This is a mild climate, with very mild frost; but gingers should still die back for winter regardless. Cannas certainly do, even without significant frost. Even some of the banana trees were somewhat unhappy about the chill.

Actually, the banana trees seem to be bothered more by chill than the gingers. Is this normal? Angel’s trumpet, cup of gold vine and blue ginger (which is not related to ginger) also expressed more displeasure than the gingers.

I really should have sheltered some of these species better. Actually, I probably should not be growing so many species that are so sensitive to chill and frost. I will be going to Southern California again in about April, so could bring back even more tropical species. It is a bad habit.

Technically, the average last frost date is about a month and a half from now. Technically, a bit of frost is possible even after that.
