Anyone got an opinion on what to do with suckers? I was taught that they just drain energy and water from the plant that could be directed elsewhere, like towards the fruit and removing them makes for a stronger plant.

This picture shows you what to look for for anyone that's unfamilar with them - the sucker is the middle one.

You see, you have a branch attached to the main stem on the left in this case. The sucker grows in between that branch and the main stem.

Now that's a big one, but I was taught to remove them while they were still tiny and throughout the plant's growth period from half a dozen inches high onwards. Apparently some let them grow bigger then snap them off and plant in potting soil to make a new plant.

This is the first I'd heard of that and was wondering if anyone had done it with success?
