California’s varied climate zones mean coastal gardeners can plant lantana earlier than those in inland valleys. Finding the best time to plant lantana in california depends on your specific region and the last frost date. This guide breaks down the ideal planting windows for every part of the state.
Lantana is a tough, heat-loving perennial that thrives in California’s dry summers. It brings vibrant color to gardens, attracts butterflies, and requires minimal water once established. But timing is everything when planting this sun worshipper.
Planting too early risks frost damage, while planting too late means less time for roots to establish before winter. Let’s get the timing right so your lantana flourishes.
Best Time To Plant Lantana In California
The universal answer for the best time to plant lantana in california is spring, after the danger of frost has passed. However, “spring” means different things across the state’s diverse climates.
For most of California, the window runs from mid-March through May. Coastal areas can start as early as February. Inland valleys and high deserts should wait until April or even early May.
Lantana is native to tropical regions and cannot tolerate freezing temperatures. Even a light frost can kill new growth or damage the plant. So always check your local frost dates before planting.
Coastal Southern California
If you live near the coast from San Diego to Santa Barbara, you have the longest planting window. Frost is rare here, so you can plant lantana from February through October.
Spring planting (February to April) gives roots time to establish before summer heat. Fall planting (September to October) also works well because the soil is still warm.
- Best months: February to April, or September to October
- Soil temperature: Above 60°F consistently
- Note: Avoid planting during peak summer heat (July-August) unless you can water frequently
Inland Valleys And Central California
Inland areas like the Central Valley, Sacramento, and Fresno experience hotter summers and colder winters. Frost is a real risk from November through March.
Here, the best time to plant lantana in california is from mid-April to early June. This gives the soil time to warm up and avoids the last frost.
- Wait until nighttime temperatures stay above 50°F
- Plant after the last frost date, typically mid-April
- Finish planting by early June to avoid extreme heat stress
High Desert And Mountain Areas
In places like the Mojave Desert, Lake Tahoe, or the Sierra foothills, winters are harsh and frost can occur into May. Summer heat is intense but short.
Plant lantana from late May to early July. This is a narrow window, but it works because the soil warms quickly after the last frost.
- Best months: Late May to early July
- Key factor: Soil temperature must be above 65°F
- Warning: Protect new plants from unexpected late frosts with row covers
Understanding California’s Climate Zones
California has 16 distinct climate zones according to the Sunset Western Garden Book. Lantana grows best in zones 8-24, which cover most of the state.
Knowing your zone helps you fine-tune the planting calendar. Here is a quick breakdown:
- Zone 8-9 (Cold mountain areas): Plant in late May
- Zone 10-13 (High desert): Plant in late April to May
- Zone 14-17 (Inland valleys): Plant in April to May
- Zone 18-20 (Coastal areas): Plant in February to April
- Zone 21-24 (Southern coast): Plant in February to October
Why Soil Temperature Matters
Lantana roots need warm soil to grow. If the soil is below 60°F, the plant will sit dormant and may rot. Use a soil thermometer to check before planting.
In coastal areas, soil warms by late February. In inland valleys, it takes until mid-April. In high deserts, wait until May.
You can speed up soil warming by covering the planting area with black plastic for two weeks before planting. This is a simple trick that many gardeners use.
Step-By-Step Planting Guide For Lantana
Once you’ve chosen the right time, follow these steps for success. Lantana is forgiving, but proper planting gives the best results.
Choose The Right Location
Lantana needs full sun—at least 6-8 hours of direct sunlight daily. Less sun means fewer flowers and leggy growth.
Good drainage is critical. Lantana hates wet feet. If your soil is heavy clay, amend it with compost or plant in raised beds.
- Full sun location
- Well-draining soil
- Space plants 18-24 inches apart for ground cover types
- Space 3-4 feet apart for shrub varieties
Prepare The Soil
Lantana is not picky about soil pH, but it prefers slightly acidic to neutral (6.0-7.5). Test your soil if you are unsure.
Mix in 2-3 inches of organic compost to improve drainage and fertility. Avoid heavy fertilizers at planting time—lantana is a light feeder.
- Remove weeds and rocks from the planting area
- Loosen soil to 12 inches deep
- Mix in compost
- Level the area
Planting The Lantana
Dig a hole twice as wide as the root ball but no deeper. Place the plant at the same depth it was in the container.
Backfill with soil, gently firming around the roots. Water deeply immediately after planting.
- Water thoroughly after planting
- Apply 2-3 inches of mulch around the base, but keep it away from the stem
- Space according to mature size
Watering After Planting
Newly planted lantana needs regular water to establish roots. Water every 2-3 days for the first two weeks, then gradually reduce.
After one month, lantana is drought-tolerant. Water deeply once a week during summer, less in winter.
Overwatering is the most common mistake. Lantana prefers to dry out between waterings.
Planting Lantana From Seeds Vs. Transplants
You can start lantana from seeds or buy transplants. Each method has different timing requirements.
Starting From Seeds
If you want to grow lantana from seed, start indoors 6-8 weeks before the last frost. This means starting seeds in February for most of California.
Seeds need warmth to germinate—keep them at 70-75°F. Use a heat mat if your home is cool.
- Start seeds indoors 6-8 weeks before last frost
- Use seed-starting mix
- Keep soil moist but not wet
- Provide bright light after germination
- Harden off seedlings for one week before transplanting
Transplant seedlings outdoors after the last frost date. This aligns with the best time to plant lantana in california for your zone.
Using Transplants
Transplants are easier and give faster results. Buy healthy plants from nurseries in spring.
Look for plants with dark green leaves and no yellowing. Avoid root-bound plants with circling roots.
Plant transplants at the same depth as their container. Water well and mulch.
Caring For Lantana After Planting
Once planted, lantana requires minimal care. It is one of the easiest perennials for California gardens.
Fertilizing
Lantana does not need much fertilizer. Too much nitrogen produces leaves instead of flowers.
Apply a balanced, slow-release fertilizer at planting time. Then feed once in midsummer if growth is slow.
- Use a 10-10-10 or 14-14-14 formula
- Apply sparingly—half the recommended rate
- Avoid fertilizing after August to prevent tender growth before winter
Pruning
Prune lantana in late winter or early spring before new growth begins. Cut back by one-third to one-half to shape the plant.
Remove dead or damaged branches. This encourages bushier growth and more flowers.
Deadheading (removing spent flowers) is optional. Lantana blooms continuously without it, but deadheading keeps plants tidy.
Winter Protection
In colder areas, lantana may die back to the ground in winter. Mulch heavily around the base to protect roots.
In coastal areas, lantana stays evergreen. Prune lightly in spring to remove winter damage.
If a hard freeze is forecast, cover plants with frost cloth or burlap. Container plants can be moved indoors.
Common Mistakes When Planting Lantana In California
Even experienced gardeners make mistakes. Here are the most common ones to avoid.
- Planting too early: Frost kills new growth
- Planting in shade: Few flowers and leggy growth
- Overwatering: Root rot and yellow leaves
- Overfertilizing: Lots of leaves, few flowers
- Planting in heavy clay: Poor drainage kills roots
Another mistake is ignoring your microclimate. A south-facing slope warms faster than a north-facing one. Adjust your planting time accordingly.
Also, do not assume all lantana varieties have the same cold tolerance. Trailing types are more tender than shrub types.
Best Lantana Varieties For California
Choosing the right variety helps ensure success. Here are top picks for different needs.
For Ground Cover

Frequently Asked Questions
Can I plant lantana in summer in California?
Yes, but it is not ideal. Summer planting requires more water and care. If you must plant in summer, do it in the evening and water daily for two weeks.
What is the latest I can plant lantana in California?
In coastal areas, you can plant through October. In inland valleys, plant by early June. In high deserts, plant by early July. Later planting risks insufficient root establishment before winter.
Does lantana come back every year in California?
In frost-free areas, lantana is a perennial and comes back every year. In colder zones, it may die back to the ground but regrow from roots in spring. In very cold areas, treat it as an annual.
How do I know when the last frost has passed?
Check your local extension service or use online frost date calculators. A general rule: wait until nighttime temperatures stay above 50°F for at least a week.
Can I plant lantana in fall for spring bloom?
Yes, in coastal areas. Fall planting gives roots time to establish over winter. In inland areas, fall planting is risky because frost may kill new growth. Stick to spring planting in colder zones.
Final Tips For Success
Lantana is a rewarding plant for California gardens. It thrives on neglect once established. The key is getting the timing right.
Remember these points:
- Know your climate zone and last frost date
- Wait for soil temperature above 60°F
- Choose a full sun location with good drainage
- Water deeply but infrequently after establishment
- Prune in late winter for best shape
With proper timing, your lantana will bloom from spring until the first frost. It will attract butterflies, bees, and hummingbirds to your garden. And it will do all this with very little water or fertilizer.
So check your local frost dates, prepare your soil, and plant at the right time. Your California garden will thank you with months of color.
If you are still unsure about the best time to plant lantana in california for your specific location, ask your local nursery. They know your microclimate best. Happy planting.
