Lantanas are low growing shrubs prized for their clusters of small fragrant flowers. The flowering season lasts from late Spring to mid Autumn. Whatever their colour, it changes as they age. A single flowerhead can contain flowers of 2 or 3 colours- yellow, orange and reddish.
Germination Temperature (°F)
Water plentifully as often as necessary during active growth period. Keep compost moist, but never allow pots to stand on water. During the rest period water only enough to keep the compost from completely drying out.
Apply standard liquid fertilizer every 2 weeks when plant is in active growth period.
Move small plants into pots one size larger whenever roots appear through drainage holes. Lantanas flower best in small pots, 6-8 inch pot size is the largest likely to be required to grow a small bushy plant.
In mid-Summer propagate from 3 inch cuttings of non flowering shoots below a leaf, strip lower leaves and dip cuttings in hormone rooting powder. Plant in a mixture of moistened equal parts of peat moss and perlite. Enclose in a plastic bag or propagator and stand in bright filtered light. After rooting occurs 2-3 weeks, uncover the new plants and water them sparingly.
Grow lantanas in bright light with at least 3 hours a day of direct sunlight. If they have too little sunlight, they will not be able to bloom. Lantana Camara is the only species that flourishes indoors.
They can be kept for years if properly pruned. As plants age, they will retain their shape if cut back to within 4-6 inches of the base in late Winter or early Spring.
Whiteflies are attracted to yellow sticky traps, or boil 2 large lemon peels in 4 cups of water for 10 minutes. Let cool and remove peels. Place solution in a spray bottle. This works on whiteflies and soft bodied insects.
Young Lantanas rooted from cuttings are likely to flower more abundantly than older plants. These plants are particularly susceptible to attack by whiteflies.
While Lantanas are in normal room temperatures, increase the humidity by standing pots on trays of moist pebbles.
All parts of the oleander (Nerium oleander), a beautiful Mediterranean-native flowering shrub, are poisonous. Ingesting oleander leaves can cause gastrointestinal, cardiac, and central nervous system problems and possible death.
