Plants that don't like themselves

[Rosefriend]

My neighbour from across the road came into the garden today and asked me why I planted things that didn't like themselves.

As she is a Landscape Gardener I didn't throw her out of the garden immediately, I just asked her what she was talking about.

She walked around and said well:

Parsley - should not and can not be planted where it has been for the last 4 years - it doesn't like itself!!??

Snowdrops - instead of becoming more , they need to be pulled apart regularly!!??

Margeriten ( Leucanthemum/Chrysathemum) - have to be taken out every couple of years!!??

Begonias (remembered from last year) - soil must not be used for other plants.??!!

Roses - never plant Roses where roses have once been planted!!?? (She did have the grace to smile as she told me that!!)

So if all this is true - what about others plants that don't like themselves??

Asters don't like being planted where asters have been before

How do these plants know these things?

[MamIDdau]

well don't certain plants take different things from the soil such as veg and maybe that's the reason? Perhaps it's like a form of crop rotation? Or maybe it makes them more susceptible to disease (with nasties lingering around) planting the same thing in the same place?
