How to grow shiso

When to plant shiso

Grow shiso in full sun to partial shade in rich, moist to dry soil; it is very heat- and drought-tolerant and grows quickly once warm (NC State). It self-seeds prolifically and is listed as invasive in several southeastern states, so pinch off flowers before they set seed to limit spread.

Shiso is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
