"Companion Planting is the growing together of all those elements and beings that encourage life and growth; the creation of a microcosm that includes vegetables, fruits, trees, bushes, wheat, flowers, weeds, birds, soil, microorganisms, water, nutrients, insects, toads, spiders, and chickens." - John Jeavons, How to Grow More Vegetables Than You Ever Thought PossibleHow to Grow More Vegetables, Eighth Edition: (and Fruits, Nuts, Berries, Grains, and Other Crops) Than You Ever Thought Possible on Less Land Than You ... (And Fruits, Nuts, Berries, Grains,)

Pumpkins are related to gourds and squash, this family includes vine crops: summer and winter squash, pumpkin, melons and cucumber.

Corn

It's advisable to plant crops which react favorably to decomposition of organic matter from preceding crops after one which produces coarse organic decomposing material. Sweet corn produces coarse refuse that doe's not easily decompose. Vine crops such as Pumpkin accelerate decomposition of the crop refuse from corn.

Corn when companion-planted with squash or pumpkin is said to disorient certain insects pests and protect the vining crop . In reciprocation, pumpkins prickly vines are said to discourage raccoons and some rodent pests from chowing down on the sweet corn.

I don't have much of a raccoon problem anymore {my 2 German shepherds handled that issue very nicely } but a few years back - I did , my corn was unmolested - whether it was due to this planting scheme or just dumb luck I can't say for certain.

The pumpkin provides a living mulch, as it cools soil and hence the corn roots in summers heat. Spent corn stalks get pulled after harvest , which precedes that of the pumpkin, and allows the pumpkins to ripen till their harvest in late fall.














Weed suppression of the corn-pumpkin combination was substantiated by a 2012 study conducted in Zimbabwe - ["The results indicate that intercrops with 33% pumpkin population and weeded at 3 and 8 WAP are superior in terms of weed biomass suppression. Intercropping done at correct crop combination and weeding at the right time therefore shifts crop-weed competition in favour of the crop as it reduces dry matter accumulation of the weeds without affecting yield of component crops. Inter-oes not provide an edibcropping can therefore be used as a component in integrated weed management in the smallholder sector." ] [1]

Beans

Pumpkins and beans work well together. The nitrogen fixing qualities of the beans are well documented and pumpkin is a heavy nitrogen feeder. Pumpkins have been successfully inter planted with beans for Centuries, a fairly recent study lends scientific credence to this combination. [2]

Potatoes

Avoid planting Pumpkin in proximity to, or in the same plot that Potatoes have recently grown - recent being the last several seasons. Potato and Pumpkins inhibit one another's growth.

Both Pumpkin and potato plants require elevated levels of organic nitrogen and potassium and there is heated competition between the two as they need the nutrients at roughly the same time. Pumpkins also increase the susceptibility of potatoes to blight.

Natural Ways To Get Rid of Garden Pests

Marigold does not provide an edible crop, merely an aesthetic one, but it is a work house in companion planting schemes. Inter-planted with pumpkin it helps to deter many pests.

Marjoram, Nasturtium, Oregano will also help in pest suppression. The marjoram will provide a ground cover/mulch as well.



Nasturtium also repels squash bugs, and striped pumpkin beetles.

Pest Suppression

Please keep in mind that many inter-actions are also percentage based. If an insect that attacks a certain garden plant is repelled by another type of plant - that doesn't mean that absolutely no insects of the genus in question will go near the plants in question - it simply means a much lower percentage than normally would have attacked the plant will show up.



Comfrey leaves are recommended to prevent scab - this is unproven

Fennel is allelopathic to most garden plants and should be avoided. It exudes compounds designed by nature to eliminate competing plants from its immediate area. Dill is one of the few garden crops that can be grown with it.
