Extending tomato height

So how do you get the more prolific top tiers? Do you grow 4,5 or more fruiting branches. I’ve got a few this year that I have allowed to topple before training up a pole. This makes spotting those troublesome base side shoots easy but watering is a little tougher as the fruiting branches are so close to the ground, none of these plants have topped out yet they still have growing space. I’m not sure they will fully ripen the top tiers as they were so late going in but we’ll see how they get on.
