growing nasturtiums in South Carolina
As easy as these plants are purported to grow, they have never thrived in my yard in several different sites in the ground or in pots. I know they like plenty of sun and poor soil but in full sun all day they do not do well. I am thinking our sun is much too hot. Any thoughts?
Nasturtium is rated for heat zone 8 and cooler. Parts of South Carolina are in zone 9, most is in 8. You may be correct that nasturtium won't do well in your state. When on the cusp of heat zone tolerance, some afternoon shade is probably best. Nasturtium grows faster as weather starts to cool in late summer/early fall. Let's hope your plants revive enough for you to enjoy them. To learn more about heat zones, read this article: http://ahsgardening.org/gardening-resources/gardening-maps/heat-zone-map
