Quarantine, why not do some indoor gardening? How about grow some carrots at home?

The carrot (Daucus carota subsp. sativus) is a root vegetable, usually orange in colour, though purple, black, red, white, and yellow cultivars exist.The carrot is a biennial plant in the umbellifer family Apiaceae. At first, it grows a rosette of leaves while building up the enlarged taproot. Fast-growing cultivars mature within three months (90 days) of sowing the seed, while slower-maturing cultivars need a month longer (120 days). The roots contain high quantities of alpha- and beta-carotene, and are a good source of vitamin K and vitamin B6, but the belief that eating carrots improves night vision is a myth put forward by the British in World War II to mislead the enemy about their military capabilities.

*Nutrition

Raw carrots are 88% water, 9% carbohydrates, 0.9% protein, 2.8% dietary fiber, 1% ash and 0.2% fat. Carrot dietary fiber comprises mostly cellulose, with smaller proportions of hemicellulose, lignin and starch. Free sugars in carrot include sucrose, glucose, and fructose.

The carrot gets its characteristic, bright orange colour from β-carotene, and lesser amounts of α-carotene, γ-carotene, lutein, and zeaxanthin.α- and β-carotenes are partly metabolized into vitamin A, providing more than 100% of the Daily Value (DV) per 100 g serving of carrots (right table). Carrots are also a good source of vitamin K (13% DV) and vitamin B6 (11% DV), but otherwise have modest content of other essential nutrients (table).

The provitamin A beta-carotene from carrots does not actually help people to see in the dark unless they suffer from vitamin A deficiency. This myth was propaganda used by the Royal Air Force during the Second World War to explain why their pilots had improved success during night air battles, but was actually used to disguise advances in radar technology and the use of red lights on instrument panels. Nevertheless, the consumption of carrots was advocated in Britain at the time as part of a Dig for Victory campaign. A radio programme called The Kitchen Front encouraged people to grow, store and use carrots in various novel ways, including making carrot jam and Woolton pie, named after the Lord Woolton, the Minister for Food. The British public during WWII generally believed that eating carrots would help them see better at night and in 1942 there was a 100,000-ton surplus of carrots from the extra production.

*How to grow/Tips*
Carrots are direct seeded in the garden rather than being transplanted and disturbing the roots. Carrot seeds can take up to 15 days to germinate. Keep the soil moist until seedlings appear.

*Soil
Choose fertile, loose, neutral or slightly acidic soil, preferably sandy loam, which is good for irrigating and draining.

*Temperature
he temperature of germination: 20℃-25℃
the growth temperature: 17℃-23℃

*Humidity
70-80%

*Sun Exposure
Full sun to light shade

*Fertilization
Potassium sulphate compound fertilizer

When to harvest your carrots will depend on the variety you are growing, but the average is about 50 to 75 days from seed.

Hope you will have a good harvest!
