The exact identity or lineage of this seed lot should be confirmed from supplier records before making a stronger claim. Growing facts Scientific name Ocimum tenuiflorum L. Life cycle Annual Maturity 50-59 Days Germination 5-10 Days at 70–85 °F Seed depth 1/8 in Plant height / spread 19–24 in Growth habit Shrubby/Subshrub Spacing 10 in between plants; 18 in between rows Sunlight Full sun Soil Loamy; pH 6.0–6.5 Water Moderate Support No-Support Starting Holy Basil (Tulsi) Green Leaf from seed Sow 1/8 in deep and keep the seed zone evenly moist. Expect emergence in 5-10 Days when the seed-zone temperature is near 70–85 °F. Germination preparation: Use a fine, evenly moist seed-starting mix or prepared seedbed. Light requirement: Light aids germination; barely cover. Soaking: None required. Stratification: None required. Scarification: None required. Planting and care Plant during late Spring and provide full sun. Space plants 10 in apart with 18 in between rows. Use loamy with a pH near 6.0–6.5, and follow a moderate watering plan. Support requirement: No-Support. Frost response: Tender. Medium to large container or in-ground bed; avoid crowding Harvest and use Approximately 50-59 Days, from transplanting to the first substantial leaf harvest. Weather, soil temperature, and planting method can shift the actual harvest date. Harvest: Harvest leafy tips before heavy flowering; allow selected plants to flower fully for seed. Uses: Fresh leaves, tea or culinary use, pollinator flowers, containers, and seed saving. Flavor: aromatic leaves shaped by the named basil type. Seed saving: Open-pollinated herb or leafy crop. Best uses include fresh leaves, tea or culinary use, pollinator flowers, containers, and seed saving. Flavor and eating quality: aromatic leaves shaped by the named basil type. Saving seed Select several healthy, true-to-type Holy Basil (Tulsi) Green Leaf plants that match the expected shrubby/subshrub habit and overall plant form. Avoid saving seed only from the earliest or largest individual unless that is your deliberate selection goal. Pollination system: Open-pollinated herb or leafy crop. Compatible plants of the same species may cross to varying degrees through insects or wind. Separate compatible varieties that may flower together, or use cages, barriers, hand pollination, or another documented control appropriate to the crop. Allow selected plants to pass the eating stage and reach full botanical seed maturity. Harvest only when seed heads, pods, or fruits have matured enough for sound seed development. Clean the seed carefully, dry it thoroughly away from direct heat, label the lot with variety and year, and store it cool, dark, and dry. Test germination before an important planting or distribution season. Common problems Common concerns: Aphids, whiteflies, spider mites, slugs, damping-off, root rot, and leaf diseases under humid crowded conditions. Management: Provide airflow, drainage, moderate fertility, careful watering, and clean harvest practices. Contain spreading mints where needed. Diagnosis note: Similar symptoms can have different causes. Compare plants of the same age, record weather and irrigation, and use local Extension or diagnostic support before applying a control.
