I don't know anything about the senna and the only way I've ever been able to share lemon balm was by digging up a clump and potting. No trouble that way at all. Keep it moist and in shade for a week or so and it'll do fine.

Lemon balm should root easily in water, if I remember correctly. I have so much of it I just pot some up like rootdigger.

The lemon balm I attempted to root just died over time instead of rooting. I don't have enough plants to dig up a clump- that would certainly be easy if I did. My one clump is a tall plant, and I want to root some pieces to share.

I'm responding in hopes that somebody may see this again and have tips on rooting Christmas Senna and Lemon Balm?

Seeds and Roots

The only way I've ever known anyone to propagate more plants from either Senna or Lemon Balm is by sowing seeds or dividing roots. I've never heard of anyone getting cuttings to root. I'm sure someone out there has but no one that I know ever has.

let your lemon balm seed, just once, and you'll have more seedlings than you can shake a stick at. it is a veritable weed for me(albeit good smelling). never grew the senna so i can't advise there. tam

What Tammy says is true. Next year you will have more lemon balm. I have some in a pot which came up from a potted plant that I brought from my previous home in Pittsburgh where I had been growing it in the ground. It is now growing in a couple of places on my property. Adele

Thanks for the feedback. I snipped back all my flowering herbs just a couple of weeks ago to avoid seeds- wouldn't you know it! I'll let it flower again and hope for seeds soon. Friends are meeting together Oct. 1 for a Plant Swap.

I didn't know that Senna could be split at the roots. I may try that. I'll look up as much information on the roots as possible before cutting anything. Thanks again!

I learned something about lemon balm. My whole motive in rooting them was to share with friends at a Plant Swap on Oct. 1, so I really hoped to find a way. I personally don't need more lemon balm:-)

I found out that lemon balm must be similar to Hydrangea in that it roots best when weighted to the ground while still attached to the plant. I found some rooted limbs today while snipping the plant back and potted them up.

Also cutting it back seems to help it spread.
