Frequently Asked Questions

How often should I water Borlotto Supremo Nano beans during flowering and pod set?

During flowering and the start of pod development, keep the soil consistently evenly moist—typically about 1 inch of water per week total, split into 2–3 watering days. Let the top 1 inch of soil dry slightly between waterings, but don’t allow the root zone to dry out fully, which can cause poor pod set. Use a deep soak rather than frequent light sprinkling to keep pods forming reliably.

How do I know when Borlotto Supremo Nano beans are ready to harvest?

Harvest for dry beans when pods are fully filled and the plants’ pods are mostly dry and papery, usually around 90 days from sowing. For best results, pick pods on a dry day, then finish drying indoors until beans rattle inside the pods and are hard enough to resist denting. If you want shell beans earlier, harvest when pods are plump but seeds are still tender and the skins are glossy, then dry lightly before storage.
