Comment by David Trout yesterday
Here is a list of my vegetable guilds so far. These guilds are based on companion planting books and charts that I have studied. There seems to be some science behind companion planting, particularly regarding the attraction of insect predators, and the intermixing of plants whose roots reach into variable layers of soil, taking advantage of nutrients and minerals by drawing them in and storing them in their leaves. When those plants die and are left to decompose in situ, these nutrients may be made available to other plants in the garden bed. Plants like comfrey may be cut back severely several times a year and their leaves used to mulch fruit trees and other garden beds.
Not all companion charts agree on every association and there are discrepancies. Much of the information concerning companion may simply be folklore. However, planting in this way encourages diversity in the garden, and the addition of many flowering annuals and perennials intermingled with the vegetables. At the very least, this results in an attractive garden to diverse forms of wildlife, AND the human eye!
Bee balm (Monarda didyma)
mint (Keep parsley and mint away from each other.)
pot marigold French, mexican
Poached egg plant (limnanthes douglasii)
Consider putting some peppers close to the wall of the house to benefit from the heat
Plant a thick parsley bed
Horseradish (Plant in containers in the potato patch to keep away Colarado potato bugs. Horseradish increases the disease resistance of potatoes.)
Hyssop (Companion plant to cabbage and grapes, repels cabbage moths and flea beetles.)
Latium (Repels potato bugs)
Cilantro repels beetles
Cabbage likes borage!! :)
Oregano (Can be planted with most crops but it is especially good for cabbage.
Plant oregano near broccoli, cabbage and cauliflower to repel cabbage butterfly.
Plant Oregano with cucumbers to repel cucumber beetle.)
Alyssum makes a perfect living mulch.
Cabbage (Keep marigolds away from cabbage.)
Comfrey (When comfrey is established, wrap each potato seed with a leaf as you plant it. This will provide the necessary nutrients to help potatoes flourish)
Nasturtium (Although they might attract cabbage flea beetles.)
Any suggestions would be appreciated
