Growing Nasturtiums in Zone 7B

Nasturtiums are edible, pest-trapping flowers with peppery leaves and vibrant blooms.

Zone 7B enjoys a long growing season. You can often get two plantings of cool-season crops (spring and fall).

Top Growing Tips

• Direct sow after frost — they don’t transplant well
• Use as trap crops for aphids — they attract pests away from vegetables
• Flowers, leaves, and seeds are all edible (peppery, like watercress)
• Too-rich soil produces lots of leaves but fewer flowers
• Trailing varieties are beautiful in hanging baskets and window boxes

Companion Planting

Good companions: tomatoes, cucumbers, cabbage, beans — excellent trap crop

Avoid planting near: none — nasturtiums are beneficial companions

Harvest Timeline

Flowering begins 50-60 days from seed; use flowers and leaves fresh
