PLACEMENT & CULTIVATION
Easy to grow nasturtiums are a delight of summer and fall, for they require so little care and few soil inputs. Regular, nitrogen-poor soil tips the scales favoring flower production over lush foliage growth. Add to vegetable gardens for their peppery flavors and attraction to pollinators, grow smaller types in pots and allow the trailing varieties to climb–with a bit of help–fences and trellis. Nasturtium's large seeds make them easy to plant, a good choice for budding young gardeners. Pick handfuls and place into old sea-green glass canning jars for perfect bouquets.
About 1" per week—drought tolerant once established, however regular watering may encourage more blossoms.
Slightly acidic to neutral
Do not fertilize, as this will limit blooms and stimulate excess foliage growth. Add 1" compost to poor soils.
Diseases & Pests:
Aphids may pose a problem—treat with an insecticidal soap if hosing down daily does not resolve the issue.
When to Cut for Bouquets:
Fully opened flowers
