Still Afraid to Prune Your Lantana?

You may have either the purple lantana or the multi-colored lantana. Most of it died back during the winter. But where to cut? What if I cut it back too far. Will I kill it? Even in February you still have time. This is lantana that has been cut back. Notice how the new growth (late January or early February just after a warm spell) is growing now. It is growing from “joints” along the stems we prefer to call “nodes”. These are places which can have alot of plant tissue that can regrow after the plant has been damaged. In this case it is “damage” either by winter cold or by pruning. Cut lantana back close to the ground so that you leave at least  two “joints” left sticking up out of the ground. Lantana is now starting to regrow from the base now in early February. It is not obvious. If you look closely at yours you will see some new growth emerging very close to the ground. The plant will “tell you” where to cut. Cut 1/4 to 3/8 inch above a node. If you are in a cold and windy part of town you will experience winter dieback of the plant closer to the ground so you will have to prune it with fewer “joints” left.

Not Too Late to Trim and Fertilize Lantana

We generally grow two types of lantana in the landscapes in southern Nevada; the purple one and the one that is multi-colored, usually with some yellow and rose or pink flowers. Both are handled about the same way in watering, pruning and fertilizing. Multi-colored lantana (L. camara) but at this point only showing just yellow flowers but can change to orange or pink later. The flowers can vary in color.   This is the purple species (L. montevidensis) sometimes called trailing lantana or weeping lantana. It was collected and propagated for sale near Montevideo, Uruguay, hence the Latin name. Come take a tour of Montevideo and see where L. montevidensis came from Both of these plants came out of South America, around Bolivia, Peru and Uruguay area where it does not freeze where it is a widespread native. Not truly a ‘desert’ plant but tolerates dry or semiarid environments near the coastline. It is now widely planted all over the tropics and subtropical parts of the world where it does not freeze back in the winter. It showed some promise in the desert and arid parts of the southern US and now is quite common. Some people would say now it is over planted but it still gives a nice show of color in the summer with little care. It will freeze back here and rebound in the spring. Pruning or Cutting the Back. The purple lantana is common now and I get alot of questions about how far back you can trim them. Take a close look at this picture. I took it a short time back when I first saw green coming from a winter pruned shrub.They can get kind of lanky and loose some eye appeal as well as die back in our colder climate so many people cut them back in the winter. It is always a good idea to wait until the coldest part of the winter has past before you cut them back or the may freeze back further. Lantana pruned back. This is fine.   See how the new growth is coming from the “joints” or “nobs” on the stems? These are nodes where buds or stems were located. They are places that contain the potential for new growth. Cut them back leaving a couple of these or more between your cut and the ground. Then they will have these spots to generate some new growth for this season. Fertilizer. Just before the really start pushing some new growth (late January or even into Februray), fertilize them. Liquid fertilizers like Miracle Gro or Peters do a great job as long as you apply enough water when the plant is growing. Less expensive fertilizers will work as well but just make sure you use one that is used for flowers or tomatoes or other flowering plants. You can apply the fertilizer dissolved or diluted in water in a plastic bucket and pour it slowly around the plants or you can apply it dry just under the drip emitters. One application is normally enough until next year. Never apply it after about August or you could affect how much winter dieback you get. It normally does not need any iron added but doesn’t hurt either. Hmmm…. none say to use on Lantana! What do I do now? You like the flowers. Promote the flowers. Use a fertilizer that promotes flowers. So you can use tomato fertilizer or rose fertilizer as a substitute. What’s wrong with this lantana? Just TLC; water, soil improvement and fertilizer. AND it was planted too close to the curb. It should be back in about three feet. It’s growing toward the south where there is more light and probably the one emitter it has.
