Care Guide
How to Water
Water only when the soil is completely dry to the touch — typically every 10 to 14 days in summer and even less in winter. Lavender is highly susceptible to root rot from overwatering. Always water at the base of the plant, avoiding wetting the foliage.
Lighting
Lavender needs at least 6 hours of direct sunlight per day to bloom abundantly. Choose the sunniest spot in your garden. In very hot climates, light afternoon shade can prevent heat stress.
Ideal Soil
Use light, sandy, well-draining soil with a pH between 6.5 and 7.5. Amend with coarse sand or perlite to improve drainage. Avoid heavy clay soils that retain moisture, as these promote root rot.
Recommended Pot
Terracotta or unglazed ceramic pots are ideal as they allow the substrate to breathe and excess moisture to evaporate. Ensure the pot has generous drainage holes. Slightly smaller pots are preferable — lavender blooms better when mildly root-bound.

How to Propagate
Stem Cutting
Take cuttings in spring or early summer using non-flowering stems. Avoid waterlogging the medium. After 3-4 weeks, test rooting by gently tugging the stem.
- 1 Cut a healthy stem 10-15 cm long just below a node
- 2 Remove the leaves from the lower half of the stem
- 3 Dip the base in rooting hormone powder
- 4 Plant in light, well-draining medium (50% sand + 50% potting soil)
- 5 Keep lightly moist in bright indirect light until rooted
Materials needed:
Seed Sowing
Lavender germination can be slow and uneven. Cold stratification significantly improves germination rates.
- 1 Cold stratify seeds in the refrigerator for 4 weeks before sowing
- 2 Sow in light, moist seed-starting mix
- 3 Cover lightly with a thin layer of mix
- 4 Keep in a warm location (18-21°C) with indirect light
- 5 Transplant seedlings when they reach 5-7 cm tall

Common Problems
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Crown Rot
Crown rot is a serious fungal disease that attacks the crown (base) of the plant where the stem meets the soil. It is caused by various fungal pathogens including Phytophthora, Fusarium, and Rhizoctonia. The disease thrives in waterlogged conditions and can quickly spread to kill the entire plant if not addressed promptly.
Gray Mold (Botrytis Blight)
Gray mold, caused by the fungus Botrytis cinerea, is a widespread necrotrophic pathogen affecting over 1,400 plant species. It thrives in cool, humid conditions and attacks weakened or aging plant tissues, causing soft rot and characteristic gray fuzzy growth.
Septoria Leaf Spot
Septoria leaf spot is a destructive fungal disease caused by Septoria lycopersici, particularly devastating during seasons of moderate temperature and abundant rainfall. The disease starts on lower leaves and progresses upward, causing small circular spots with tan to gray centers and dark brown margins. If left untreated, it can dramatically reduce plant yields and cause complete leaf blight.
Meaning & Symbolism
In Mediterranean and European tradition, lavender symbolizes calmness, purity, and devotion. It is also associated with serenity, emotional balance, and spiritual renewal. In many cultures, it represents love and grace.
