New Jersey gardeners find success planting lantana in mid-May once nighttime temperatures stay above 50°F. Knowing the best time to plant lantana in new jersey is crucial for getting vibrant blooms all summer long. This guide walks you through everything you need to know for a thriving lantana patch.
Best Time To Plant Lantana In New Jersey
The best time to plant lantana in New Jersey is after the last spring frost, typically from mid-May to early June. Lantana is a tropical plant that absolutely cannot handle cold. If you plant it too early, a late frost will kill it. Wait until the soil has warmed up and nighttime temperatures are consistently above 50°F.
Why Timing Matters So Much
Lantana originates from warm climates. It goes into shock if exposed to temperatures below 50°F. Planting too early means stunted growth or even death. Planting at the right time gives your lantana a strong start for the entire growing season.
- Lantana stops growing below 55°F
- Frost kills the foliage instantly
- Cold soil prevents root development
Checking Your Local Frost Dates
New Jersey spans USDA hardiness zones 6a to 7b. The last frost date varies. In northern NJ, it can be as late as May 15. In southern NJ, it may be as early as April 20. Always check your specific county’s average last frost date before planting.
Frost Date Ranges By Region
- North Jersey (Sussex, Passaic): May 10–May 25
- Central Jersey (Middlesex, Mercer): May 1–May 15
- South Jersey (Atlantic, Cape May): April 20–May 5
Use a local weather app or your county extension office for precise dates. Dont rely on just one source. Check a few to be safe.
Preparing Your Garden For Lantana
Before you plant, prepare the site. Lantana loves full sun and well-draining soil. It does not like wet feet. Choose a spot that gets at least 6 to 8 hours of direct sunlight each day.
Soil Requirements
Lantana is not picky about soil pH. It grows well in slightly acidic to neutral soil (pH 6.0 to 7.5). The most important factor is drainage. If your soil is heavy clay, mix in compost or sand to improve drainage.
- Test your soil drainage: dig a hole 12 inches deep and fill with water
- If water drains in 1 to 2 hours, drainage is good
- If water takes longer, amend the soil with organic matter
Hardening Off Transplants
If you buy lantana from a nursery, it was likely grown in a greenhouse. You need to harden it off before planting. This means gradually introducing it to outdoor conditions over 7 to 10 days.
- Day 1–2: Place plants outside for 2 hours in shade
- Day 3–4: Increase to 4 hours, some direct sun
- Day 5–6: Leave out for 6 hours, full sun
- Day 7: Leave out overnight if temps stay above 50°F
Skipping this step can shock the plant and delay growth for weeks.
Step-By-Step Planting Guide
Follow these steps for the best results. The exact timing depends on your local weather, but the process is the same.
When To Plant Lantana In New Jersey: The Exact Steps
- Wait until after the last frost date for your area
- Check the 10-day forecast for no cold snaps
- Choose a sunny morning for planting
- Dig a hole twice as wide as the root ball
- Place the plant at the same depth it was in the pot
- Backfill with soil and water thoroughly
- Space plants 12 to 18 inches apart for spreading varieties
Container Planting Tips
If you grow lantana in pots, you can plant a bit earlier. Containers warm up faster than ground soil. But still protect them if a late frost is predicted. Move pots indoors or cover them with a frost blanket.
- Use pots with drainage holes
- Choose a potting mix for flowers
- Water more frequently than in-ground plants
Caring For Lantana After Planting
Once your lantana is in the ground, care is simple. It is a low-maintenance plant. But a few key practices will keep it blooming from June until the first fall frost.
Watering Needs
Lantana is drought-tolerant once established. But newly planted lantana needs regular water. Water deeply once a week if there is no rain. In sandy soil, water twice a week. Overwatering can cause root rot, so let the soil dry out between waterings.
Fertilizing
Lantana does not need heavy feeding. Too much fertilizer leads to lots of leaves but few flowers. Use a balanced, slow-release fertilizer at planting time. Then feed once more in mid-summer if blooms slow down.
- Use a 10-10-10 fertilizer
- Apply at half the recommended rate
- Water after fertilizing
Deadheading And Pruning
Lantana is self-cleaning, meaning old flowers drop off naturally. But you can trim spent flower clusters to encourage more blooms. In late summer, if the plant gets leggy, cut it back by one-third. This promotes bushier growth.
Common Mistakes To Avoid
Even experienced gardeners make errors with lantana. Here are the most common pitfalls and how to avoid them.
Planting Too Early
The biggest mistake is planting before the soil warms. Lantana will just sit there and not grow. It may even rot. Always wait until nighttime temperatures are reliably above 50°F.
Overwatering
Lantana hates soggy soil. If leaves turn yellow, you are watering too much. Let the soil dry out completely before watering again. In clay soil, water even less.
Too Much Shade
Lantana needs full sun to bloom well. In partial shade, it becomes leggy and produces few flowers. If your garden is shady, consider growing lantana in a container that you can move to a sunny spot.
Lantana Varieties For New Jersey
Not all lantana varieties are the same. Some are more cold-tolerant than others. For New Jersey gardens, choose varieties that can handle a bit of cool weather.
Top Recommended Varieties
- Lantana camara ‘Miss Huff’ – very cold hardy, blooms until frost
- Lantana camara ‘New Gold’ – compact, golden flowers
- Lantana montevidensis – trailing type for hanging baskets
- Lantana ‘Bandana’ series – heat-tolerant, compact growth
These varieties have performed well in New Jersey trials. They are more likely to survive a chilly night in early June.
Extending The Blooming Season
With proper timing, lantana blooms from June to October. But you can extend the season even further with a few tricks.
Using Frost Protection
In early fall, watch the forecast. If a light frost is predicted, cover your lantana with a frost cloth or old bedsheet. This can buy you an extra 2 to 3 weeks of blooms.
Overwintering Lantana
Lantana is a perennial in warm climates, but in New Jersey it is grown as an annual. However, you can overwinter it indoors. Before the first frost, dig up the plant, pot it, and bring it inside. Place it in a bright, cool room and water sparingly. In spring, move it back outside after the last frost.
- Cut back the plant by half
- Pot in a container with drainage
- Keep in a 50–60°F room
- Water only when soil is dry
- Reintroduce outdoors in May
Frequently Asked Questions
Here are answers to common questions about planting lantana in New Jersey.
Can I Plant Lantana In July In New Jersey?

What Happens If I Plant Lantana Too Early?
If you plant lantana too early, it may stop growing or die. Cold soil and air temperatures stress the plant. Leaves may turn purple or yellow. The plant may never fully recover.
Is Lantana Invasive In New Jersey?
Lantana is not considered invasive in New Jersey. It does not spread aggressively in our climate. However, it can self-seed in mild winters. Deadheading prevents unwanted seedlings.
How Long Does Lantana Bloom In New Jersey?
Lantana blooms from June to the first hard frost, usually in October. That is about 4 to 5 months of continuous color. Deadheading is not required but can boost bloom count.
Can I Grow Lantana From Seed In New Jersey?
Yes, but it takes time. Start seeds indoors 8 to 10 weeks before the last frost. Lantana seeds germinate slowly. Most gardeners prefer buying transplants for faster results.
Final Tips For Success
