Lantanas can bloom from June through early October in Georgia. Lantana lace bug can stop blooming in the summer leaving green plants with no blooms. Adult lace bugs are long, oval insects with a midsection that is slightly wider than the ends.
The rear of the lantana lace bug is blunt but rounded off. The young are dull-colored and spiny. Look for the lantana lace bug by shaking the branch over a piece of white paper or light-colored cloth. Lace bugs feed on the bottom of the leaves and on young flower buds. They make the top of the leaves speckled with white, similar to mite injury. Since lace bugs feed on young flower buds, lantana bloom may be severely reduced or stopped completely.
When populations are very high, the lantana leaves may turn almost white and fall from the plant. Lantana is valued for its long season of reliable bloom. Many cultivars display multiple colors within each two-inch wide disc-shaped flower head.
The flowers attract butterflies and hummingbirds. Foliage is coarse, lightly toothed and rough to the touch.
Crushed leaves have a pungent scent, so you may want to locate where the plant it will not spread across walks if the odor offends you. Use lantana as annuals or perennials in flowerbeds or containers. Spreading cultivars are attractive as groundcovers or trailing over containers and walls. Grow lantana in full sun. Lantana is tolerant of all soil types provided they are well drained and slightly acid. Lantana is tolerant to salt and is an excellent choice for plantings near the beach.
Lantana prefers warm soil. Plant lantana in spring, at least 2 weeks after all danger of frost is past. Hardy lantanas will typically show no growth in the spring until soil and air temperatures are quite warm.
Water: Newly planted lantanas will need to be kept moist for the first few weeks until the roots have spread into the surrounding soil. While established lantanas are drought tolerant, performance, bloom, and growth rate will be reduced if they are too dry for a long period. During their blooming period, give them a thorough watering once a week if they do not receive an inch of rain that week.
Avoid overhead watering. Overly frequent overhead watering can make plant more susceptible to diseases and root rot. Pruning: Prune lantana periodically during summer by lightly shearing the tip growth to encourage repeat blooming. Plants that have become too large for their allotted space may be pruned back by up to a third of their height and spread. Water and lightly fertilize newly cut back plants and they will return to bloom quickly. Prune perennial lantanas back hard in spring March to remove old growth and prevent woodiness.
Cut back to about 6 to 12 inches from ground level. Avoid hard pruning in fall as this can cause reduced cold hardiness. Fertilizer: Lantana requires little fertilizer. A light fertilization in spring will usually be sufficient.
Vigorously growing plants may be fertilized again in mid summer, provided plants are not water stressed. Lantana that are establish most often do not require any additional watering and attain all the moisture they require from rainfall as they prefer the soil slightly on the dry side. Not Enough Sunlight to Flower Lantana flower to their full potential when in the most amount of sun possible with more abundant flowers and more pronounced fragrance. Bad Weather Prevents Lantana Blooming The success of your lantana displaying the most flowers possible is dependent on the weather and can fluctuate significantly from year to year due to its sensitivity to certain conditions such as excess moisture, soil fertility, and hours of sunshine.
If your lantana has not flower well this year then this may be a reaction to: Too many overcast days in Spring or Summer depriving the lantana of the hours of sun it requires for flowering. Weeks of rainfall which may not be typical to your climate have created moist conditions that are at odds with lantana preferred relatively dry habitat.
Lantana flower more in hot weather. If the temperature is unseasonably cool then this can have an impact on flowering. Lantana in Pots Not Blooming There are several reasons why a lantana may not be flowering sunlight, over watering etc. If your potted lantana is not flowering then this usually because: The pot or container is too small , so there is less soil and therefore less nutrients and capacity to hold water. The pot or container does not have drainage holes in the base which results in saturated soil and a water stressed lantana that does not flower.
Excessive drought stress from being in a small pot can potentially prevent flowering. Always plant lantana in pots with drainage holes in the base to allow excess water to escape. Lantana Not Flowering After Planting Transplant Shock Lantana plants sometimes do not flower after planting because: The contrast in conditions from where the lantana was cultivated to your garden.
Conditions such as hours of direct sun, temperature, soil moisture and soil fertility all have a direct impact on how much a lantana flowers. If the lantana has been cultivated in somewhat different conditions to your garden more light, warmer temperatures etc. This period of adjustment caused by transplant shock can temporarily prevent flowering, however the lantana can flower once it has adjusted as long as it has enough light, soil conditions and your follow the best practices of care for lantana.
The roots require time to establish in the soil. Lantanas are drought resistant once established but vulnerable to drought after planting particularly if they are planted during the hot Summer rather then the cooler Spring. Ideally plant lantana in Spring and water frequently so that the soil is moist but not boggy for the first month at which point the roots should begin to establish and you can scale back the watering to periods of drought.
Slow Draining Soils Prevents Lantana from Flowering Lantanas are native to scrubby areas of Africa and the Americas where they grow in relatively low fertility and sometimes quite sandy soil that drains quickly. Lantanas not Flowering when the Berries are Set Lantana may not flower if the berries are already set as there is less of an incentive.
Deadheading redirects the energy of the plant to producing more flowers rather then seeds. Lantana Lace Bug Impacts Flowering The lantana lace bug is a pest that feeds on the sap of leaves and flower buds and causes white marks on the leaves which can then fall off.
Insecticidal soap is available at garden centers and on Amazon for a reasonable price. Key Takeaways: The reasons for a lantana not flowering is because of a lack of sun, over watering, too much fertilizer or because of lantana lace bug which can stop flowering. Lantana require full sun, well draing soils and warm weather to flower.
