In times of scarcity, we can’t rely on the food industry to provide us with enough to eat. If you look back to the world wars where food was rationed, civilians were encouraged to grow their own produce to supplement what the state could provide. If you’re aiming toward self-sufficiency, then you should focus on the fastest growing vegetables and fruits to get you started.

There are plenty of crops that will grow with very little intervention; growing is easy if you just follow some simple guidelines:

  • Provide nutritious soil
  • Keep the soil moist (not drenched and claggy)
  • Have plenty of sunlight
  • Protect from pests

Following are some of the fastest growing vegetables and fruits that are sure to keep your table full of nutritious treats.

The Fastest Growing Vegetables and Fruits

  1. Sunflower shoots – 12 Days

This is quite an odd start, perhaps, but Jerusalem artichokes are of the sunflower family, so it stands to reason that its distant cousin could be edible. You eat the shoots as they appear – they’re tiny but they’re delicious and packed full of nutrition.

The shoots appear after just 12 days – plant a plentiful handful of seeds in a large seed tray. The plant isn’t going to grow to maturity, so you don’t particularly need depth – a couple of inches of compost will be fine. Lightly cover your seeds with half an inch of compost and keep it moist. Once the shoots have appeared and have grown two healthy leaves, they’re ready to eat. Don’t leave it too long to harvest, because they become bitter.

  1. Radishes – 21 days

Radishes are crunchy and delicious and simple to grow. You don’t need to wait for a particular season, but they’ll thrive in temperatures of between 50ºF and 65ºF.

They germinate quickly – after around three or four days you’ll spot the leafy green shoots appearing. Plant weekly for a constant supply of these crunchy salad favorites.

  1. Scallions – 21 days

Brown onions grown to maturity take around six months, but scallions are the crop that just keeps giving. Grown from seed, they should be ready for the plate in 21 days.

One of the best ways to harvest scallions is to cut them rather than pull the full root out of the ground. Once the green shoot has reached six inches in height, cut it just above the soil and add to your salad bowl. The plant will keep producing for the rest of the season.

  1. Lettuce – 30 days

Lettuce is a fast germinator and a speedy developer, but what’s most valuable about this salad favorite is that you can just break off the leaves you need and the plant will continue to grow and produce. Lettuce prefers cooler climes – between 60ºF and 70ºF is best, but green leaf and red leaf varieties are tolerant of hot weather.

Planting new seeds every 14 days will ensure a constant supply of salad leaves all season long.

  1. Spinach – 30 days

Spinach is particularly hardy, able to cope with temperatures as low as 15ºF. It grows quickly and can be planted as soon as the ground has thawed. Pluck the outer leaves and re-sow seeds every fortnight for successive harvests. You should pick regularly because the leaves will become bitter once the plant has reached maturity.

  1. Turnips – 30-55 days

Mature roots take just two months to grow, but you can pull baby turnips up much sooner for tender, mild-tasting, sweet root veg. When the leafy greens have reached a diameter of 2 inches, you can top them and add them to salads and the roots will continue to grow.

  1. Beets – 35-60 days

Beets are sweet and delicious, and the entire plant is edible. The leaves make delicious, earthy additions to the salad bowl. Only snip off one or two leaves per plant – otherwise, you could impede root production. When the top of the beetroot globe starts to show above the soil, it’s time to lift them for eating.

  1. Zucchini – 40-95 days

Each plant will produce around 6 to 10 pounds of fruit, so zucchini is a super-fast grower. Sprinkle used coffee grounds into the soil and around the plant to give the plant a caffeine-kick that gets it growing rapidly. The flowers are edible and delicious stuffed with cream cheese.

  1. Broccoli – 40-60 days

Broccoli is a super-fast germinator and delicious if picked young. Plant “Quarantina’ or “Sessantina” for quick harvests.

  1. Baby carrots – 50 days

Carrots can be left to grow to full-size or picked early for tender, sweet roots that are delicious when added whole to stews or roasted. Carrots grow quickly, and if you plan to eat them small, you don’t need to space them out – grow a ton of carrots in a pot quickly.

  1. Cucumber – 50 days

Cucumbers grow bitter with age, so pick them while they’re small and young. The fastest growing varieties are Bush Crop, Straight 8, or Sweet Success. Harvest the fruit regularly as it encourages new fruit to develop.

The Fastest Growing Food Plants

In a world that’s becoming more and more reliant on mass production, perhaps it’s time to take stock and consider what we can produce for ourselves.  If you’re concerned about the chemicals that go into the production of our food, grow your own. There’s nothing like knowing exactly where your food has come from to enhance the satisfaction of eating the fruits of your labor.

Growing is about trial and error, but the fastest growing vegetables and fruits are often the simplest to get started. Keep your soil well fertilized and watered and you could be enjoying fresh produce in no time.
