Do you need to prune lantana? Why trimming will result in prolific blooms

If you want colorful exuberance in summer, lantana are bright and heat-loving flowering plants for growing in borders or containers. You can get annual or perennial varieties and which you plant will affect how much you need to prune lantana.

There is not always a need to prune when growing lantana, as plants will happily grow and flower without much fuss. However, lantana can spread and get unruly. Pruning can control this and, in addition, plants will benefit from light trimming during their flowering period to keep them in top shape.

So the question is, should we prune lantana or not? How much pruning you need will depend on the type of lantana. It is advantageous to prune perennial lantana at least once a year to keep plants healthy and compact, while both types can be kept neat thanks to some summer pruning.

A guide to lantana pruning

Whether you usually trim or not, let’s deep dive into when and how to prune lantana for healthy and beautiful plants.

When to prune lantana

Lantana can be grown in flower beds or container gardens to provide long seasons of color from spring until the first frost. They are commonly grown as annual plants and the main pruning required for these is to deadhead lantana to keep them tidy and, in some varieties, promote a long blooming season.

Deadheading is not essential, but advisable in many cases. For example, Lantana camara is considered an invasive plant in some US states and deadheading plants will combat the spread. Many lantana varieties commonly sold are sterile though and will not produce viable seeds.

Pruning is most important when growing lantana as a perennial plant. Making time to prune lantana annually keeps the plant healthy and productive, ensuring it puts on the best show of blooms year after year.

Prune lantana back in late winter or early spring after the risk of frost has passed and before it starts to put on new growth in spring. This annual trim of perennial lantana will keep plants compact and stimulate new growth to promote flowering.

Plants will also benefit from additional light pruning throughout the year. Summer offers an ideal opportunity to trim perennial and annual lantana lightly. It can keep them compact, and neat, and promote flowering.

Scott Seargeant, an experienced landscape gardener and owner of Seargeant Landscape & Arboriculture, claims that regular trimming once established can ‘reduce shabbiness and rejuvenate’ older perennial lantana plants.

‘Prune lantana in mid-summer if it is starting to look overgrown, shabby or losing the foliage and flowers in the center of the plant,’ recommends Scott. ‘It will look semi-woody inside or underneath. This could be the second or third summer after planting.’

You can prune lantana in the fall or early winter, however, the old flower heads can be beneficial in a wildlife garden as a food source for birds and the stems can protect the crown during the colder months.

How to prune lantana

As mentioned above, lantana will benefit from being cut in late winter and summer in different ways. Whenever you prune lantana, use clean and sharp pruning shears to avoid damaging plants and spreading diseases around the yard and aim to make pruning cuts at a 45-degree angle.

How to prune lantana plants in winter

Late winter or early spring is the time to prune lantana back hard. It would be a pruning mistake to cut lantana hard in the fall as the winter colds could get into the cuts and damage the plant.

Aim to trim the lantana stems to 6-12 inches from the ground and remove any older, damaged, or diseased stems to keep the plant productive. Scott Seargeant advises: ‘Prune off the dead stems back to living tissue. Look for green color from the cut ends to determine where the living parts are.’

How to prune lantana plants in summer

Lantanas are fast-growing plants that benefit from light cosmetic trimming throughout the growing season to keep them looking their best. Long or straggly stems can be trimmed back by 1-3 inches to neaten the plant and keep it compact. Old flowers and unattractive stems are also removed to keep the plant aesthetically pleasing.

Scott Seargeant recommends a mix of pruning methods in summer to keep lantana under control. He says: ‘I like to prune lantana with a combination of heading cuts (cutting the ends back) and thinning cuts (removing a whole stem back to near where it comes out of the ground). This reduces bushiness and reduces the diameter size of the plant.’

Taking time to fertilize lantana after summer pruning will help the plant bounce back well from any trimming. Feed plants with a water-soluble bloom-boosting fertilizer, such as this food for flowering plants at Walmart, to encourage the lantana to produce more flowers during the summer.

FAQs

How do I get more blooms on lantana?

Lantana wants full sun - at least six hours a day - and regular watering to guarantee a great display of flowers. Deadheading the plant once the flower head fades will also concentrate the plant’s energy into creating more blooms rather than producing berries.

Should you remove seed pods from lantana?

Yes, prune off the seed pods as they develop to keep the plant blooming. You can leave the pods to collect seeds, however, as previously mentioned, many lantana hybrids are sterile and will not produce fertile seeds. Furthermore, the seeds from other hybrid cultivars may not produce the same flowers as the parent plant once sown.

Lantana are fantastic low-maintenance plants to have as part of a garden for pollinators. Their colorful flowers attract bees, butterflies, and hummingbirds in droves throughout lantana’s long blooming season. If you want a spectacular and easy-to-grow plant for pollinators, then lantana ticks all the right boxes.
