Plant Characteristics
Basic Information
- Category: Herbs & Weeds
- Suitable Location: outdoor garden bed in a sunny, well-drained spot
- Suitable For:
- Is Weed: No
- Allergenicity: low
Environmental Needs
- Climate: {"temperatureRange":"5–35°C"}
- Hardiness: {"zones":"5–9"}
- Misting: rarely required, only if grown in very dry indoor conditions
- Drainage: Fast-draining to prevent root rot.
- Soil Type: Well-draining, loamy soil with added organic matter; can tolerate poor soils but thrives with good drainage.
Maintenance Level
- Maintenance Level: low
- Toughness Level: high
- Pruning Frequency: Every 4–6 weeks during the growing season; lightly prune after flowering.
- Pruning Intensity: Light to moderate; avoid removing more than one-third of the plant at a time.
Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from harsh afternoon sun in hot climates; ensure good air circulation to prevent mildew.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun
Rotate plants for even growth; use sheer curtains to filter intense light indoors; avoid placing in shaded areas for prolonged periods.
Watering
every 7–10 days, allowing soil to dry between waterings
Water deeply but infrequently; ensure soil dries between waterings; avoid overhead watering to prevent fungal issues.
Soil
well-drained, sandy loam with moderate fertility
pH: Slightly alkaline to neutral (pH 6.5–7.5).
Ensure pots have drainage holes; avoid heavy clay soils; amend with organic matter for better texture.
Temperature
Prefers 60–80°F (15–27°C); can tolerate cooler temperatures but thrives in warmth; avoid frost.
Protect from frost; provide shade in extreme heat; maintain consistent temperatures for optimal growth.
Fertilizing
every 4–6 weeks during active growth with a balanced liquid fertilizer
Fertilize lightly to avoid excessive leaf growth at the expense of flavor; stop fertilizing before flowering to enhance oil production.
Propagation
Methods
Stem cuttings or division; stem cuttings are the most common method for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in medium.
- Keep moist and warm.
Best Time: Early spring or late summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain consistent moisture.
Medium
Well-draining potting mix (e.g., perlite and peat moss) or water for initial rooting.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 2–3 weeks; plants can be transplanted in 4–6 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; keep cuttings out of direct sun; maintain humidity with a plastic bag if needed.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips to encourage branching; trim stems just above a leaf node.
Pruning Plan
Regular pruning encourages bushier growth and prevents legginess; remove spent flowers and dead stems to promote new growth.
Tools
Pruning shears, sharp scissors, gloves.
Checklist
Use clean tools; prune in early morning; remove dead or diseased growth; encourage bushy growth.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter); ensure good drainage holes.
Method
Remove plant gently; trim roots if necessary; place in a slightly larger pot with fresh, well-draining soil; water thoroughly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for container-grown plants to refresh soil and provide space.
Checklist
Choose appropriate pot size; use fresh soil mix; trim roots if crowded; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; avoid wetting leaves.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone without saturating the soil; allow excess water to drain away; water in the morning to reduce evaporation and fungal risk.
Watering Schedule Tips
Water when the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure soil is not compacted.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or browning leaf edges.
Cold Stress
Slows growth, may cause leaf drop, and increases susceptibility to disease; can die in prolonged freezing temperatures.
Solution: Move potted plants indoors during frost; cover outdoor plants with frost cloth; ensure good air circulation to prevent mold.
Hot Stress
Leaf scorch, wilting, reduced flavor intensity, and potential flower drop due to excessive heat.
Solution: Provide afternoon shade; increase watering frequency; use mulch to retain soil moisture; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during growing season; avoid winter feeding; follow package instructions.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during the growing season (spring to early fall); avoid fertilizing in winter.
