How to Grow Lantana Plants

Propagating Lantana Plants

Be aware of the benefits of growing from cuttings. If you grow Lantana from seed you have harvested, you may not get a plant exactly like the parent plant. When you propagate Lantana from cuttings, the plants you grow will be more predictable. Propagate Lantana cuttings in the spring.

Prepare the cutting for propagation. Take about five inches of fresh, healthy-looking growth, remove the lower leaves and dip the cutting in rooting hormone or powder. Then insert the lower two inches into a pot with moist cutting compost.

Cover your cutting. Cover the pot that you have placed your cutting in either with a clear plastic bag or an inverted clear plastic bottle with the spout cut off; doing this makes a mini greenhouse of sorts. Make sure the plastic doesn’t touch the cuttings; use plant sticks to support the bag and keep it away from the stem if necessary.

Keep the cutting moist. If you keep your cutting moist, it should root in about a month. After the last frosts have passed you can harden your cutting off and plant it out in the garden. Hardening off means that you slowly acclimatize your cutting to outdoor temperatures. This could mean moving it outside during the day, and then storing it in your garage overnight.

Grow your Lantanas from seed if you can’t get a healthy cutting. If you do grow your Lantana from seed, start the Lantanas off indoors about a month before the last frosts occur. Seeds may take a few weeks to germinate. If you are growing from seeds, fill a pot with potting soil and plant the seeds. Keep the pots in a cool dry place out of direct sunlight.

Planting and Caring for Lantana Plants

Understand that Lantanas can grow to a length of 1.5 meters (4.9 ft). Lantana will grow fairly slowly. Non-creeping varieties usually grow to a height of about 1.5 meters (4.9 ft). Trailing varieties only grow to about 20 inches (50.8 cm) in height but spread by several feet.

Find a spot with well-draining soil. Lantana prefers a moist but well drained soil in full sun. It will benefit from being fed regularly during the growing season, which occurs in spring and summer. Lantana prefers to be kept moist even over winter.

Prepare the soil. Start by digging the soil over and incorporating some well-rotted manure or compost to enrich the soil and improve drainage. Consider incorporating a slow-release fertilizer.

Dig a hole as deep as your plant and twice as wide. Put your Lantana in and fill the hole with soil, pressing it down with your hands. Give the plant a good soak and continue watering the plant twice a week (unless it’s very rainy) until the plant is well established; this usually takes a few months. Try to water the ground rather than soak the foliage.

Consider feeding your plant with a light feed in the spring. Established Lantana plants don’t require much attention although they will appreciate a feed in the spring. Don’t over feed them but try to apply a weak liquid feed with a general purpose fertilizer (avoid those high in nitrogen relative to other ingredients) once a month during the growing season.

Water your Lantana once a week in dry periods and lay down mulch. Apply a thick layer of mulch when the ground isn’t too cold; this will help conserve moisture and protect the roots. Once a year, remove the old mulch and reapply a fresh layer.

Trim off the growing tips every few weeks over the growing season to encourage new blooming. Cut the top inch or two from the stem tips, always cutting just above a leaf set. Remove any dead or damaged growth. Give it a good prune in the early spring before it begins growing again; cut it back to within about a foot of the ground,

Fight pests. Lantana will be affected by a few pests and diseases. Mildew may be a problem if the plants don’t get enough light. Whiteflies and lace bugs may also affect the plant. Try using a spray insecticide to control these pests if they emerge.

Bring your plant indoors during harsh winters. If you are in a zone cooler than zone 9 (where temperatures drop below 20 degrees Fahrenheit or -6.7 degrees Celsius), you’ll need to bring your plant indoors in the fall. Water it occasionally through the winter. Move your plant outside again when the temperatures improve.

Ongoing Care for Trailing or Creeping Lantana

Give your trailing Lantana lots of light. Trailing varieties of Lantana are pretty robust and will tolerate drought but do need plenty of light. They will tolerate a small amount of shade for some of the day but you’ll see them grow leggy (with long stems rather than compact bushy growth) and produce fewer blooms if they aren’t getting enough sun and water. You can encourage bushy growth to make good ground cover by pinching the plant back. To do this, remove the stem tips just above where each stem branches into two stems. This will encourage more side branches to form.

Don’t let your trailing Lantana get too dry. Although Trailing Lantana tolerates drought, it will bloom better if it doesn’t get too dry. Water once or twice a week during dry periods.

Trim your Lantana. Removing spent flowers will encourage new ones to form so don’t be shy about trimming the bush during the growing season. You should try to trim just above a leaf set.

Prune your Trailing Lantana. Every few years the Trailing Lantana may get a little too woody and overgrown. A vigorous prune to within a foot of the base will usually rejuvenate the plant. Do this over the dormant season in winter or early spring.

Pruning Lantana Plants

Prune before growth begins. Lantana benefits from being pruned in the mid-springtime before growth begins. This will improve flowering later in the season. Avoid pruning in the fall.

Remove any dead, damaged or diseased growth. Remove any branches that are crowded or grow over other branches. Cut back the Lantana by about a third of the size of the plant. Give the plant a liquid feed after pruning.

Lightly prune during the growing season. During the growing season you should lightly prune your Lantana, as this will encourage new flowering. Take about two inches off each growing tip with a sharp pair of garden scissors. This should encourage new growth. It’s always a good idea to feed the plant after pruning.
