🛒 Green Beans — Seeds & Supplies
- 🌱 Bush Bean Seeds
- 🌱 Pole Bean Seeds + Trellis Set
- 🌱 Rhizobium Inoculant
Search for these at your local garden center or nursery.
Growing Tips
- Sow seeds directly — beans don't transplant well.
- Bush beans mature all at once (great for canning). Pole beans produce over a longer season.
- Inoculate seeds with rhizobium bacteria for better nitrogen fixation and yield.
- Pick beans before you can feel the seeds bulging inside the pod.
- Don't work in the bean patch when plants are wet — spreads fungal disease.
Common Mistakes
- Starting indoors — direct sow only, 1 inch deep after last frost.
- Over-fertilizing with nitrogen — you'll get lush plants with few beans.
- Letting pods mature on the vine — this signals the plant to stop producing.
- Planting near onions or garlic — these inhibit bean growth.
Companion Planting
Companion planting improves growth, deters pests, and makes better use of garden space.
