crinums in winter

| I've never really grown crinums before, but after reading about them and admiring them from afar, I went out and bought several this past summer and planted them in various places throughout my yard. They all did really well for the rest of the growing season, and some of them even flowered a bit. Now that we're into winter, though, I'm wondering how to handle them to maximize their health and survivability, knowing their hardiness they can be a little borderline around here. With other marginally hardy perennials, some of them do best if they're mulched heavily over winter, while others prefer to be left dry. Which category are crinums in? And should I cut back the foliage, tie it up, leave it alone, or does it not matter? Any advice or insight would be greatly appreciated. Thanks! |

| As the foliage is frost killed, I pull it off and compost it. I always fear that insects, etc. could overwinter in that mess. I topdress the area around the bulbs for about a foot radius with about an inch of Black Kow (per Marcelle Shepard's website) and then add several inches of pinestraw or chopped leaves. I have had mine about five years now, but so far, we have not had a true zone 7 winter..... I'm impressed that your bulbs bloomed the first year. Were they potted up or bare root? If bare root, what kind were they? |
