Just as you have a supply of candles and batteries or even a generator on hand for power outages, and a supply of bottled water available in case of a water shutoff in your neighborhood, it’s probably a good idea to always have crops growing in your home and garden to sustain yourself if there is an interruption in delivery of fruits and vegetables to the grocery store or, for that matter, a breakdown in the supply chain of food transport in general. “Survival Gardening” (Storey Press, 2025), by Sam Coffman, addresses this concern.

The most instant food source is sprouts, and you grow them in nothing but water. Many types of seeds meant for this purpose, after being soaked for 12 hours or less, will have sprouted and may be consumed in three to five days.

Seeds grown for their sprouts include several types of beans, black sunflower (meatier than ordinary sunflower seed), broccoli, cabbage, chickpea, fenugreek, kale, chives and many others.

Microgreens are grown from many of the same seeds as sprouts except they require soil. Seeds from which you grow microgreens must be kept in the dark for a few days to a week while the greens begin to grow, and then are exposed to light for another week so that the total time from planting to harvest is around two weeks.

Although microgreens have less amino acids than sprouts, they are more nutritious in terms of vitamin and antioxidant content.

Moreover, microgreens are 40 times more nutrient-dense than mature plants grown from the same seeds. All cole crops — broccoli, cauliflower, kale, Brussels sprouts, cabbage, collards, mustard greens and kohlrabi — can be grown as microgreens, but many other seeds are also recommended for growing in this manner.

It should be noted that dried beans — whether kidney, mung, pinto or lentils — sold in grocery stores can be used for growing sprouts or microgreens.

Coffman devotes a chapter to cultivating mushrooms, since they are a preferred crop for indoor growing. Two kinds of mushrooms — lion’s mane and oyster — are also among the author’s “12 fast-growing crops,” together with arugula, green beans, kale, lettuce, mustard greens, beets, radishes, spinach, Swiss chard and turnips; all of these may be harvested after five weeks of growth.

Where mushrooms are concerned, you can grow a new crop from stems of fresh mushrooms placed in a container with sanitized (disinfectant-treated) wet cardboard. Oyster mushrooms, in particular, lend themselves to this practice.

Sweet potatoes are a highly nutritious garden crop that is easy to grow and can be a constant source of subsistence throughout the year.

Not only are the tubers good for you, the greens that grow from them are edible and equally salubrious. Please note that sweet potatoes have no botanical kinship with ordinary potatoes, whose green growth is highly toxic.

Chickens are a source of eggs and offer a constant supply of manure — after at least three months of aging — for the survival gardener.

Bringing in a rooster has its advantages, since it will ward off predators and provide new chicks for your flock. Then again, a rooster can be a noise nuisance in the early morning hours, and it requires its own space or it may become aggressive with and harm the hens.

Coffman extols the production of worm castings (a euphemism for worm poop) through the proliferation of red wriggler worms, easily ordered from online vendors.

Castings are a ready-made fertilizer that can be topically strewn around plants. The mineral nutrients will be soaked into the soil by rain or irrigation and absorbed by roots. You can make a simple device out of a 5-gallon bucket with holes drilled in the bottom and the sides.

Raise the bucket off the ground on stakes or bricks to make sure air circulates below. Fill the bucket halfway with shredded paper or newsprint together with a little garden soil and sand.

Now add your worms and, a day later, any of the following materials: vegetable and fruit peelings, eggshells, sawdust, hair, barnyard manure, leaves and plant clippings.

The author delves into certain cringeworthy subjects that have their place in the context of survival gardening.

“Humanure” is human waste that has been composted for at least 12 months to remove unhealthy microorganisms. The author also explores the topic of insect consumption.

Among the insect dishes mentioned are grasshopper fajitas, baked locusts with soy sauce and honey glaze, cricket coconut soup, deep-fried beetle salad, stir-fried scorpions in ginger sauce, and wolf spider tempura.

If there is a nuclear event, you will want to test the soil before planting to make sure it is free of heavy metals such as cesium and strontium.

One of the best plants for absorbing these toxins is the sunflower. In the Chernobyl area, where a nuclear disaster occurred in 1986, sunflowers have been used to decontaminate soil.
