In the yard it will just get mowed of course, cool, fine.
In random places in the garden beds, not so good. Plus, I like to utilize this stuff or at least give the herb away so others can enjoy the
As its Greek/Latin name says, Melissa means bee and you can surmise this is a great bee attractor with its tiny little flowers develop later. This is a plus as I am trying to attract more pollinators, so the plan is rather than seek and eat/destroy this herb, I'll be moving it around to far corners of the yard to try to increase bee/pollinator production, yet keep it in places where I hopefully will not accidentally drag seed around when I cut the stalks. It's always so hard for me to cut the stalks when there are flowers on it because the nectar starved bees go at them even when they're in seed it seems. Another note: CARRY A PLASTIC BAG TO HOLD SEEDS IN WHEN I CUT THE SEED STALKS OFF. This would probably prevent all the seeds from going everywhere in the first place.
Unorganized gardening (bending down for a weed here that catches my eye, pruning there) walking aimlessly around in the garden is fine, fun and relaxing, but you'd think I'd have learned my lesson with crazy plants like perilla/shiso/beefsteak plant and now lemon balm. Brill.
