Neighbour constantly parks close to the boundary and her kids constantly walk all over my plants

[gardenfever]

So basically my neighbour closes practically on the boundary that separates our homes just so her garden area at the front isn’t blocked by her car.

Every single time her kids will walk all over my plants.
Its one of those bay parking drives so a fence would stick out like a sore thumb.
Any suggestions on how to stop this as I am sick of her kids standing all over my plants.

Hi thanks everyone
I am still looking for planters that are tall enough.

You could use this type with trellis for hight if sufficient space.

Where are the plants? A diagram would be useful-I don't see why you can't have a fence.
