The Dark Side of Companion Planting

I posted a chart a while back about the benefits of companion planting.  Now let's take a look at the flip side of that coin.

There are some herbs/plants that do not play so well with others.  Some plants engage in a sort of chemical warfare with other plants.  The general term for this is alleopathy.  It's the releasing of chemicals by one plant that inhibits or detrimentally affects the condition of some plants around it.  Seems plants are more like humans than we thought!

Here is a list of some of the bully plants & the ones they like to pick on:

Plant Bully	Victim
Anise	Carrots
Black Walnut	Most Vegetables, Azaleas, Rhododendrons, Blackberries, Lilacs, Peonies, & Apple trees
Chives	Beans & Peas
Chrysanthemum	Lettuce
Coriander	Fennel
Dill	Carrot, Tomato, & Fennel
Fennel	Beans & Peppers
Garlic	Beans & Peas
Larkspur	Beets
Mustard	Turnip
Onion	Beans, Peas, & Sage
Rue	Basil, Cabbage, & Sage
Sage	Onion
Tansy	Collards
Wormwood	Most Vegetables

Perhaps this will explain some of your mysterious failures!
