I seem to be one of the few folks who can’t figure out how to reliably grow nasturtiums. Every year, I either sprout the seeds or direct sow them, and nearly every year most of the plants fail. This year, some did okay, but others stayed miniscule, like this one.
I should have put something in to show the scale, but it’s barely 3 inches across, as opposed to others from the same seed packet that grew to span nearly a foot with many showy orange or yellow blooms. The tiny blossoms of the fleabane (Erigeron karvinskianus) visible in the photo give at least some idea – they are probably no more than 1/2 inch wide themselves. I have no problems growing that plant, it wants to take over the entire garden!
I’ve heard that nasturtiums don’t like too much water and don’t care if the soil is fair to poor, but that doesn’t explain my troubles – several were planted in the exact same bed but the results were completely different.
I liked the variegation concept initially but then, on the plants that looked less healthy, it was hard to tell from a distance which parts were light by design and which were just sickliness showing.
I love this cheerful plant with its bright, edible flowers and rambling habit, but can’t seem to get it right. Does anyone have any hints?
