Title: Branching on plants
Author: Barbara Medford

QUESTION:

Hi Mr SmartyPlants, I would like to cause my cerus peruvinesus (sp?) to branch low to the ground and another plant to branch higher up..what causes branching & how can I duplicate this?

ANSWER:

Not even Google could find the plant by the name you gave us, but after playing around a little bit, we discovered Cereus peruvianus, sometimes called the "night-blooming cereus." This is an upright cactus plant, originating in Brazil, Uruguay and Argentina. The Lady Bird Johnson Wildflower Center is dedicated to the promotion and propagation of plants native to North America; therefore, this plant (if it's the plant you're talking about) is somewhat out of our area of expertise. However, we did find a couple of websites that might help you out. The first one is Cereus Peruvianus-The Least and Best Known Cactus. The other website is a page of images of Cereus peruvianus.

Your second question, on branching and how to duplicate it, I'm afraid we're not going to be much help there, either. Are you talking about a woody shrub or tree? Another cactus? Generally, speaking, plants branch where they wish to, they can't be trained to put out a branch where one is wanted. What you can do is trim off unwanted branches to expose more trunk, at least on a woody plant. Since we didn't give you the information you wanted, here are two suggestions: (1) If, after looking at the pictures of the Cereus peruvianus, you don't feel that is the plant you are talking about, perhaps you could send us a picture and see if we can identify it. There are instructions for sending a digital picture in the lower right hand corner of the "Ask Mr. Smarty Plants" page. (2) If you have a specific type of plant you want to try to change or control the branching on, you might let us know what that is, and we'll see if we can find some help for you on that issue.

Question: February 08, 2010 - I want to plant a desert willow and a salvia greggii in my small lot. The developer used sandy loam to fill in the small garden in the front. I am 73 and a bit impaired. Do I really need to remove all that loam and replace it, or can I just put good soil on top of it and plant? I assume that my sacks of Garden Soil from Miracle Grow are not going to get it. What should I use?

Question: February 08, 2010 - I bought a Campsis trumpet vine cultivar in 2006 and planted near my fence in my yard hoping to cover the fence with the vine. Well 4 seasons later the vine has grown about 5 ft. in area but has yet to produce one flower. It does fill in beautifully with green delicate leaves but it never flowers. What could cause it to not flower. It is in partial shade which the tag says plant in sun to part...
