brunnera - Knowledgebase Question

Purchased brunnera Jack Frost in May and planted in large pot on full shaded porch. Watered regularly, fertilized every other week. Plant looked great until mid-June. Leaves & stems breaking at ground level, almost seemed to rot away. Tried more sun exposure, less watering-no use. Do they like more acidic soil? Did I overwater? Would like to try it again but need to know more about this plant. Would Hadspen Cream or Looking Glass be hardier?

What you describe sounds like crown rot, brought on by overly moist (poorly draining) soil. Brunnera like moisture but requires fast-draining soils. In your growing region, they prefer morning sun and afternoon shade. If you try again, use a good grade potting soil and make sure there's adequate drainage holes in the bottom of the container. Water throughly, then allow the top half-inch of soil to dry before watering again. The key is to have the potting soil damp but not soggy wet. Stick your finger down into the soil; if it is still moist 2" beneath the soil surface, you won't need to water for a day or two. If it's dry, it's time to water again. Hope this information helps you grow healthy Brunnera!
