In Louisiana: watch for

The pests that find green beans here.

With about 276 frost-free days, bush bean spends longer in the ground here than in most of the country, which widens the window in which mexican bean beetle can find it. Scout weekly from midseason and act on the first signs.

Mexican bean beetle

Coppery ladybug-like beetles; leaves skeletonized to lace.

Organic fix: Handpick adults and yellow egg clusters; neem.

Aphids

Clusters on the shoot tips.

Organic fix: Insecticidal soap or neem.

Rust & powdery mildew

Orange or white spots on leaves late in the season.

Organic fix: Water at the base, space plants, spray neem.

Anthracnose

Sunken dark-red cankers on the pods, and leaf veins turning brick-red to black underneath.

Organic fix: Start with certified seed, water at the base, and stay out of the patch while the leaves are wet.

Your season math: Louisiana gives green beans about 276 frost-free days, and it needs roughly 55 days to a first harvest. That fits about 23 re-sown rounds across the season, so you can keep it coming instead of picking once.
