Q.balsam impatiens
I love the balsam but have had problems with them growing too tall and am having to stake and tie them, can they be pruned to reduce height? I don’t want the stop flowering but they get really unruly before I can harvest the seeds.

When they start getting too tall, just cut them back a few inches after a flush of bloom. Deadheading can help if you pinch off a couple of inches when you remove the faded blooms.
