Harvesting
Fresh or Snap Beans and Fresh Peas: Harvests can take
place every few days once plants start producing pods that are
of the desirable size. More picking generates more flowers
and more pods later. Bush-type beans are commonly machine
harvested and sorted with a once-over pass. Time from
seeding to harvest ranges from 50 to 60 days for beans, or 6070
days for peas.
Dry Peas and Dry Beans: Harvests can take place as onceover
harvests when pods are dry. Machine harvests should
take place before noon when plants are slightly damp to avoid
pod shatter. Time from seeding to harvest ranges from 70 to
120 days for beans, or 80 to 100 days for peas.
Southern Peas and Lima Beans: Target harvests for fresh
products when the seeds are succulent, and the pods are juicy.
When the first beans are ready plants can be hand harvested
for fresh product about once per week. A once-over harvest is
used for dry seeds. Time from seeding to fresh harvest ranges
from 60 to 70 days for southern peas, or 60 to 90 days for
lima beans. For dried seeds, time from seeding to harvest can
be over 100 days.

Beans (Dry), Southern Peas/Cowpeas | Use disease-free seed.
Rotate to non-host crops for 3 years. Varieties with partial
resistance are available, depending on the race of the
pathogen. Prompt destruction of the finished crop with tillage
to rapidly breakdown tissue is an important method to
prevent disease build-up.
