Thyme / Lemon
Thymus × citriodorus (Pers.) Schreb.Thyme / Lemon is maintained at Green Grass Grove as a named cultivar or selection with value for culinary herb production. Low, spreading woody perennial with citrus-scented foliage; named clones vary in variegation and vigor.

Botanical Overview
Thyme / Lemon is maintained at Green Grass Grove as a named cultivar or selection with value for culinary herb production. Low, spreading woody perennial with citrus-scented foliage; named clones vary in variegation and vigor. At the Live Oak site, management centers on lemon thyme needs the same dry crown and strong drainage as culinary thyme but is often less tolerant of neglect in containers, accurate accession labeling, and seasonal performance records.
Ethnobotanical, Bioactive & Cultural Documentation
Cultivar-specific claims are used where the name is verified; otherwise values are species-level, regional extension guidance, or clearly identified operational inference for Live Oak, Florida.
Why We Feature This Specimen
At Green Grass Grove, Thyme / Lemon provides a focused demonstration of herb production under North Florida heat and humidity. Visitors can compare flowering, wildlife use, drought or moisture response, and seasonal maintenance without exposing private inventory or location data.
Climate & Protection
Cold protection trigger: Begin cold protection below 38 °F. The cold-damage threshold is the lower temperature where injury becomes likely, not the recommended waiting point.
Sun / Light: Full sun; very light afternoon shade is acceptable.
Lemon thyme needs the same dry crown and strong drainage as culinary thyme but is often less tolerant of neglect in containers. North Florida summer rain can cause rapid decline if roots remain wet.
Heat-zone and verification notes
Not assigned; use seasonal temperature and site-performance guidance.
Planting & Seasonal Guide
Starting & Germination Methods
Seed Sowing
Seed sowing is the umbrella operational method for placing botanical seed into a germination environment. It includes selection of containers or beds, medium, depth, spacing, moisture, temperature, light,…
Open Full Method ↗Lemon thyme needs the same dry crown and strong drainage as culinary thyme but is often less tolerant of neglect in containers. North Florida summer rain can cause rapid decline if roots remain wet. Plant at a season that allows roots or seedlings to establish before the profile's main stress period. For Live Oak trials, record sowing or planting date, emergence, first flowering or harvest, storm damage, freeze response, and summer survival.
Spacing: 12–18 inches apart
Planting Depth: Transplant at crown level; seed will not reliably reproduce named lemon-scented clones.
Pollination: Allow representative healthy plants to flower for seed and pollinator records. Preserve isolation and accession identity where cultivar or provenance matters.
Water, Soil & Nutrition
💧 Water & Moisture
Irrigate sparingly after establishment and keep foliage dry overnight. Use a fast-draining container medium for valuable clones.
North Florida humidity changes the risk profile for this plant. Dense foliage and aromatic herbs should be spaced for rapid leaf drying and watered at the root zone. After heavy rain, inspect crowns and lower foliage for spotting, mildew, or rot, and remove collapsed material before it becomes a disease reservoir.
🌱 Soil & Growing Media
Preferred pH: 6.50 to 8.00
↘ Drainage & Root-Zone Behavior
✦ Nutrition & Deficiency Checks
Use soil testing and moderate, crop-appropriate fertility rather than a universal fertilizer recipe. Leaf and shoot harvests respond to balanced fertility, but excessive nitrogen can dilute aroma and attract aphids. On Live Oak's sandy soils, split small applications when feeding is necessary and verify pH before treating suspected micronutrient problems.
Diagnose pale, distorted, or weak growth by checking root condition, moisture, pH, and recent weather before adding fertilizer. Nitrogen shortage may reduce vigor, while iron or magnesium unavailability can cause chlorosis; however, waterlogging, heat injury, root disease, or salt accumulation can produce similar symptoms. Use soil or tissue testing for persistent problems rather than treating leaf color alone.
Growth, Maintenance & Harvest
Maintenance & Pruning
Clip tender tips regularly to maintain a dense mound. Do not remove all green growth from woody stems. Pruning should preserve the crown, maintain airflow, and support the intended use. Do not remove more living tissue than the plant can replace during its active season, and sanitize tools between accessions when disease is suspected.
Harvest or Observation
Clip tender tips regularly to maintain a dense mound. Do not remove all green growth from woody stems. Use clean tools, avoid harvesting wet diseased material, and record yield or ecological observations by accession. Where the plant is not an ordinary food crop, harvest language refers to research, seed, propagation, or habitat maintenance rather than human consumption.
Storage & Preservation
Use fresh, freeze, or dry gently to retain citrus aroma.
Harvestable Plant Parts & Uses
Clip tender tips regularly to maintain a dense mound. Do not remove all green growth from woody stems. Use clean tools, avoid harvesting wet diseased material, and record yield or ecological observations by accession. Where the plant is not an ordinary food crop, harvest language refers to research, seed, propagation, or habitat maintenance rather than human consumption.

Open Full Method ↗Aquaponics, Hydroponics & Aeroponics
Aquaponics
Aquaponic use is not a default recommendation. Any trial requires strong root aeration, crop-appropriate support, sanitation, and separation from the primary living collection.
Hydroponics
- Target pH5.8–6.5
- Target EC1.0–1.6
Use the stated pH and EC only as a conservative starting range for a monitored trial; adjust by crop response, water quality, and system analysis.
Aeroponics
No profile-specific aeroponic recommendation is assigned without controlled trial evidence.
Pests, Diseases, Safety & Toxicology
Scout Thyme / Lemon for aphids, mites, whiteflies, thrips, leaf miners, caterpillars, slugs, and species-specific root or stem pests. Confirm the organism before treatment and protect flowering beneficial insects.
Monitor Thyme / Lemon for damping-off during propagation, root or crown rot in saturated media, and leaf spots, rusts, or powdery mildew under humid crowded conditions. Separate disease from heat, freeze, drought, and nutrient injury.
Maintain Thyme / Lemon in the light, drainage, and containment system appropriate to its identity. Prune or harvest to preserve airflow, prevent unwanted seed or rhizome spread, and replace declining woody or diseased material.
Likely operational problems include lemon thyme needs the same dry crown and strong drainage as culinary thyme but is often less tolerant of neglect in containers, establishment failure from incorrect moisture, and disease where airflow or drainage is poor. Competition, lodging, self-sowing, rhizome spread, or identity drift may also matter depending on the specimen. Do not interpret a single season's performance as a fixed cultivar trait without repeated observations.
Ordinary culinary use is generally considered low risk for correctly identified material, but concentrated extracts, essential oils, medicinal dosing, allergy, pregnancy, and drug-interaction questions fall outside this horticultural profile. Do not substitute a garden accession for a standardized medical product.
Wash harvests in potable water, cool promptly, and follow every pesticide label and preharvest interval. Keep essential oils and concentrated preparations away from children and pets, and stop use if irritation or allergy occurs.
