Permastead

"Permastead" was a lazy portmandeau of "permaculture" (itself a portmandeau of "permanent" and "agriculture" in case you didn't know) and "homestead" - a search indicated it's not in wide use so I'm using it.

Here we are

A blog for the learning of all the things for creating permasteading (permanent-agriculture "permaculture" influenced modern homestead principles and practices).

Parsnip

Family: Apiums
Role: Companion, Fodder
Helps: fruit trees
Helped by:
Attracts: a variety of predatory insects
Repels:
Avoid:
Details: The flowers of the parsnip plant left to seed will attract a variety of predatory insects to the garden, they are particularly helpful when left under fruit trees, the predators attacking codling moth and light brown apple moth. The root also contains Myristricin, which is toxic to fruit flies, house flies, red spider mite, pea aphids, a simple blender made extraction of three blended parsnips roots to one litre of water through a food processor (not one for preparing food) and left overnight, strained and use within a few days.

Carrot

Family: Apiums
Role: Food, Companion
Helps: Tomatoes, alliums, beans, leeks, lettuce, onions
Helped by: Lettuce, alliums (chives, leeks, onions, shallots, etc.), rosemary, wormwood, sage, beans, flax
Attracts: assassin bug,lacewing, parasitic wasp, yellow jacket and other predatory wasps
Repels: leek moth, onion fly
Avoid: Dill, parsnip, radish
Details: Beans provide the nitrogen carrots need more than some other vegetables. Aromatic companion plants repel carrot fly. Alliums inter-planted with carrots confuse onion and carrot flies. Flax produces an oil that may protect root vegetables like carrots from some pests.

Sage, rosemary, and radishes are recommended by some as companion plants, but listed by others as incompatible. For the beneficial insect-attracting properties of carrots to work, they need to be allowed to flower; otherwise, use the wild carrot, Queen Anne's Lace, for the same effect. Tomatoes grow better with carrots, but may stunt the carrots' growth.
