3. Why Does Lantana Repel Mosquitoes?
The plant synthesizes triterpenes, lantana, and essential oils that serve as a natural defense against herbivores.
For us, the scent is almost imperceptible; for Aedes aegypti, Culex, and company, it’s a means of escape.
Field research shows a significant reduction in mosquito population in areas decorated with lantana compared to those without.
The more vigorous the plant, the greater the emission of these volatile substances.
4. Growing Checklist — From Zero to a Blooming Garden
Substrate: Slightly acidic mix (pH 6-6.5) with good drainage; organic compost plus coarse sand works well.
Pot: Minimum 25 cm deep; generous hole in the bottom with a layer of expanded clay or gravel.
Sun Exposure: Six hours of full sun per day ensure continuous flowering.
Watering: Moderate; allow the topsoil to dry before watering again. Avoid standing water.
Fertilization: Biweekly in spring and summer with NPK 10-10-10 or sifted compost. Suspend in winter.
Pruning: Cut tips after each flowering to encourage lateral shoots; remove dead branches.
Pest Control: Mostly pest-resistant, but check for mealybugs; clean with a damp cloth and diluted mild soap.
Propagation: Cuttings of 10 cm semi-woody branches; plant in light substrate until rooted.
5. Planting Step by Step for Beginners
Prepare the Container
Line the bottom of the pot with 2 cm of pebbles and cover with a bidim blanket to hold the substrate.
Mixing the Soil
Combine three parts topsoil, one part sand, and one part humus. Fill to within 3 cm of the rim.
Position the Seedling
Center the lantana, accommodating the roots without bending them. Fill with substrate and press lightly.
First Watering
Water until the water runs out of the drain. Top up substrate if necessary.
Acclimatization
Leave in partial shade for three days; then expose to full sun.
