Frequently Asked Questions

How often should I water large-leaf basil during the main growing phase?

During active growth, keep the top 1–2 inches of soil consistently moist but never waterlogged. In warm Full Sun conditions, this typically means deep watering about 1–2 times per week, then adjusting to heat so the soil doesn’t dry out between waterings. Mulch helps, but let excess surface moisture drain so basil roots don’t sit in soggy soil.

How can I tell when Ocimum basilicum is ready to harvest (leaf large Italian style)?

Harvest when plants reach about 8–12 inches tall and have well-formed leaves, typically around 55 days from sowing. Pick leaves in the morning before they get hot, cutting above a pair of leaf nodes to encourage branching. If the plant starts forming flower buds, begin harvesting more frequently because leaf quality declines as it bolts.
