Tips on Pruning Lantana for Big Blooms… and What to Avoid

Lantana plants are a favorite among gardeners due to their vibrant colors and heat-tolerant nature. However, just like any other plant, they need proper care and maintenance to reach their full potential. One essential aspect of caring for lantana plants is pruning.

Pruning your lantana not only helps to maintain its size and shape, but also encourages healthy growth and flowering. It is a simple yet crucial process to ensure your plant thrives all season long. This article will offer you guidance on how and when to prune lantana, so you can keep your garden looking stunning.

When to Prune Lantana

Pruning your lantana plants is essential for maintaining their health, appearance, and encouraging growth.

To ensure you’re pruning at the right time, consider two key factors: seasonal timing and the blooming cycle.

Seasonal Timing

The best time to prune lantana is during late winter or early spring, just before new growth begins. This will promote strong, healthy growth in the upcoming season. In most regions, this occurs around February or March.

  • Late winter or early spring: Prune your lantana plants during this time to encourage new growth.
  • Summer: Light pruning can be done during the growing season to maintain shape and encourage continuous blooming.
  • Avoid fall pruning: Pruning in the fall can stimulate new growth, making the plant more susceptible to frost damage.

Blooming Cycle

Lantanas have a unique blooming pattern that consists of continuous blooming throughout the growing season. To maximize their flower production and promote a bushy growth habit, consider the following:

  • Deadheading: Regularly remove spent flowers to encourage the plant to produce more buds.
  • Light pruning: Trim back long, leggy branches during the growing season to maintain a compact, bushy shape.
  • Pinching: Gently pinch off the tips of new growth when the plant is young; this will encourage a fuller, more rounded shape as it grows.

Types of Pruning


Thinning is an essential pruning technique for maintaining a healthy Lantana plant. This method involves removing entire branches to improve air circulation and allow sunlight to penetrate deeper into the plant.

Thinning helps in reducing the risk of diseases and pests. To thin your Lantana, focus on removing crowded or crossing branches, and prune back to a side shoot or main stem. This will encourage new, healthy growth and maintain the plant’s natural shape.

Heading Back

Heading back is another crucial pruning technique used to control the size and shape of your Lantana plant.

In this method, you cut back branches to a healthy bud, side shoot, or the main stem.

Heading back encourages more branching and a fuller appearance, making your plant look more vibrant.

Be mindful not to over-prune, as this can cause stress to the plant; it’s best to trim no more than one-third of the total branches at a time.

A gentle touch will keep your Lantana flourishing and maintain its desired shape.


Deadheading is the process of removing faded or spent flowers from your Lantana plant. This method promotes continuous blooming and improves the overall appearance of your plant.

By eliminating the flowers that have finished their bloom cycle, you redirect the plant’s energy into producing new blooms.

To deadhead Lantana, simply pinch off the spent flower clusters as they fade. Remember to clean your pruning tools between cuts to minimize the risk of spreading diseases. Deadheading not only extends your plant’s bloom time but also creates a tidier and more appealing visual display.

Step-by-Step Pruning Guide

1. Inspect the Plant

Before you begin pruning your Lantana, take a moment to inspect the plant. Look for signs of disease, pests, or any damaged areas. Make sure to remove any unhealthy parts from the plant while you prune. This will ensure a healthier and more attractive Lantana.

2. Make Proper Cuts

When pruning, it’s essential to make the right cuts. Always cut at a 45-degree angle and about 1/4 inch above a leaf node (the spot where a leaf connects to the stem) or lateral branch. This encourages new growth and helps prevent diseases from entering the plant.

3. Remove Old Growth

Pruning Lantana involves removing old growth to promote new growth and keep the plant looking its best. Start by removing any dead, diseased, or damaged branches. You can also remove any crossing or rubbing branches, as they can lead to wounds and disease.

4. Shape the Plant

Shaping the plant is the final step in pruning your Lantana. Focus on creating a more balanced and symmetrical shape by trimming long or unruly branches.

As you shape the plant, be mindful not to remove more than one-third of the plant’s overall growth, as this can stress the plant and hinder its growth.

Remember to periodically step back and assess your pruning progress, ensuring you achieve a pleasing and healthy shape for your Lantana. And always use clean, sharp pruning tools to make clean cuts and avoid damaging the plant.

Additional Tips and Considerations

Pruning Frequency

It’s important to determine the right frequency for pruning your Lantana. Generally, you should do light pruning throughout the growing season to maintain its shape and encourage flowering.

Heavier pruning can be done in late winter or early spring, as this will promote healthy growth when the plant emerges from dormancy. Be careful not to over-prune, which can stress the plant and reduce its overall health.

Fertilizing After Pruning

Fertilizing after pruning is essential for the optimal growth of your Lantana. Applying a balanced, slow-release fertilizer, such as a 10-10-10 formula, can give your plants the nutrients they need to thrive.

Follow the packaging instructions for the correct application rate and timing. Also, water the plants after applying the fertilizer to help them reach the roots and avoid burning the leaves.

Pest Management

Pest management is crucial in keeping your Lantana healthy and vigorous. Common pests include whiteflies, aphids, and spider mites. You can prevent these by regularly monitoring your plants and treating them when you spot any infestations.

  • Whiteflies: Use yellow sticky traps to catch these flying insects. In severe cases, apply a neem oil-based insecticide to control their population.
  • Aphids: Encourage beneficial insects like ladybugs and lacewings in your garden, as they feed on aphids. You can also use a strong water jet to knock them off the plants or apply insecticidal soap to control their numbers.
  • Spider mites: Keep the area around your Lantana clean and free of debris to prevent mite infestations. If needed, use neem oil or an appropriate miticide according to the label instructions.

By following these additional tips and considerations, you’ll ensure the proper care and maintenance of your Lantana plants, promoting a healthier and more attractive garden.
