planting 3 trees of the same type as one tree (very near from each other)

Hi, i bought some littles trees of huarango or prosopis pallida , and then i planted them in my land.
But there was something wierd about these plants, I realized that each of these little trees that i bought had 3 or 4 branches comming out from the soil .

At the beginning i thought that each of these branches were comming from a "principal" branch, in other words i though that they were just one tree with 3 branches , but then i discovered that they were not one tree with 3 branches but instead they were 3 little plants , each of them independent to each other and grouped very near each other and sold as "one" plant.

I was wondering, which is the reason in the plant store they grouped independent plants into one ? Is this a good practice? or not?

Do you recommend me , separating each independent plant , or is it ok to leave at is it at this moment ( 3 plants planted very near as one plant) ?

what do you recommend me?


thanks in advance

More than likely they were planted by seed and 3+ seeds were dropped into the growing soil to ensure there would be at least one growing tree per pot.

If they are all healthy there is no reason to leave them bunched up if it's 3 seperate trees.

I am not familiar with it, so I did a search. At this link, http://en.wikipedia.org/wiki/Prosopis_pallida , it says that they multiply by seed or suckering. Maybe your tree is already suckering?

Be careful it may be connected by the roots.

Some of the pictures show it as a shrub with many trunks.
