Bee balm is an easy to grow perennial that is beloved by bees and other pollinators like butterflies and even humming birds.
Here's how I get more of it to grow:
If you have a new plant and want to encourage it to spread – or once it starts to pop up in the spring – remove the lower leaves...
...make a trench with your finger and bury the bottom part of the stem.
If the plant cells do not see light, they grow roots.
So the areas of the plant that you removed the leaves from, will grow roots and force offshoot plants to grow.
