In this tutorial, we learn how to pinch coleus plants. This plant is great for containers and the garden, but you need to pinch it for it to become more full. If it's not pinched, it will grow straight up without and lateral branching. To do this, pinch off the stem right at the base of the stem. You can do this with a pruner or your fingernails. So, instead of one stem coming from the middle, two stems will come up from separate sides. You can be rough with this plant and pinch the stem many times, because it has the ability to grow out and bush out as much as possible.
