If you’re growing lantana, June is one of the most important months of the year. This heat-loving flowering plant is famous for producing vibrant clusters of red, orange, yellow, pink, purple, and white blooms that attract butterflies, hummingbirds, and pollinators throughout the season. However, many gardeners unknowingly miss a few key June tasks that can mean the difference between a plant that produces occasional flowers and one that becomes a nonstop explosion of color until fall.
Lantana thrives when temperatures rise, making June the perfect time to give it the care it needs before the hottest part of summer arrives. By focusing on watering, feeding, pruning, and pest management now, you can encourage stronger growth, larger flower clusters, and continuous blooming for months.
Here are the 9 critical things you should do this June to keep your lantana healthy, vigorous, and covered in blooms all summer long.
1. Give Your Lantana Full Sun Every Day
Lantana is a true sun worshipper. One of the most common reasons for poor flowering is insufficient sunlight.
For the best blooms, lantana needs:
- At least 6 to 8 hours of direct sunlight daily
- Open, airy growing conditions
- Protection from excessive shade
Plants grown in partial shade often become leggy and produce fewer flowers. If your lantana is in a container, June is an excellent time to relocate it to the sunniest spot available.
Think of sunlight as the fuel that powers flower production. The more sun your lantana receives, the more energy it has to create those vibrant blooms.
2. Deadhead Spent Flowers Regularly
Deadheading is one of the easiest ways to increase flowering.
As blooms fade, the plant begins shifting energy toward seed production rather than creating new flowers. By removing old flower clusters, you encourage the plant to continue blooming.
To deadhead:
- Locate faded flower heads.
- Follow the stem down to the first set of healthy leaves.
- Snip the stem just above the leaves.
Perform this task weekly throughout June for the best results.
Many gardeners notice a dramatic increase in flower production after making deadheading a regular habit.
3. Feed With a Balanced Fertilizer
June is when lantana enters a period of vigorous growth.
A light feeding can provide the nutrients needed for abundant flowering.
Choose:
- Balanced slow-release fertilizer
- Flowering plant fertilizer
- Compost-enriched soil
Avoid excessive nitrogen. Too much nitrogen encourages leafy growth at the expense of flowers.
Apply fertilizer according to package instructions and water thoroughly afterward.
A properly fed lantana will reward you with stronger stems, greener foliage, and larger flower clusters.
4. Water Deeply but Avoid Overwatering
Lantana is surprisingly drought tolerant once established.
One mistake gardeners frequently make is watering too often.
Instead:
- Water deeply
- Allow the soil to dry slightly between waterings
- Focus on the root zone
Overwatered lantana may develop:
- Root rot
- Yellow leaves
- Reduced flowering
During particularly hot June weather, container-grown plants may require more frequent watering than those growing in garden beds.
The goal is consistent moisture without soggy soil.
5. Trim Leggy Growth
By June, some lantana plants begin producing long, unruly stems.
A light trim encourages:
- Bushier growth
- More branches
- Increased flower production
Use clean pruning shears to remove:
- Weak stems
- Overgrown shoots
- Damaged growth
Avoid removing more than one-third of the plant at a time.
Within a few weeks, you’ll notice a fuller and more compact plant loaded with fresh blooms.
6. Add Fresh Mulch Around the Base
Mulching provides several benefits during the heat of summer.
A 2- to 3-inch layer of mulch helps:
