How To Divide Boston Fern Runners  – Step By Step Guide

If you have some Boston fern growing in your home, you can propagate more using the runners.

The best time to divide them is during the fall when the leaves begin to turn brown.  But don’t wait too long because you may lose some of the runners and the plants will die off.

When you are ready to divide the runners, take a look at the base of each runner.  You will see the roots coming out from the base.  Dig up the whole plant, including the roots.  Take it outside and carefully cut the roots apart with your hands or a sharp knife.

This will separate the runners.  After you have done this, you can either leave the runners in a bucket of water for a couple of days, or you can immediately replant the runners into fresh soil.  As for the ferns themselves, they can be divided in the fall when the new growth is visible.

You can use a knife or a spade to make small, shallow holes in the ground.  When you are ready to divide the fern, you simply remove the fronds from the base of the plant.  If the fronds are very large, you may want to use a knife to make a cut in the base of the frond and then gently pull the frond apart.
