Vegetables that enjoy each other

Potatoes and B-road beans
Go well together
The beans upset insects
Marigolds top
Create a border
And you will see some order

No eel eel worms in sight and
Horse radish around
They safeguard the spuds
Then some sunflowers
Which are pretty to see
And orach grows well
With goosefoot thankfully
The soil is enriched
More balanced and will
Support the vegetables
And seeds can still
be eaten
Nutritious companions at play
All Good for the garden yes anyway?
