Potatoes grown in partial or full shade might not produce any tubers – if they do, the tubers will be small. Of course, not every part of the potato plant needs lots of light. In fact, the tubers will turn green and may become toxic if exposed to sunlight!
What happens if potatoes don’t get enough sun?
The lack of bright sunlight slows the production of glucose, which is stored in the tubers. Without enough sunlight, potato plants will grow smaller, less plentiful tubers. Potatoes need at least 6 hours of indirect sunlight per day to produce any edible tubers.
Why do potatoes need sunlight?
Do potatoes need light to grow? Potatoes, like all root vegetables, produce edible tubers under the soil. But the leafy portion of the plant above ground needs light; almost all vegetables use sunlight for photosynthesis – the process through which they convert nutrients into the starches that will feed the plant.
Do potatoes do well in shade?
Potatoes. Potatoes prefer cooler weather. While potatoes will thrive in full sun, the plants will also tolerate partial shade as well. Expect a lower yield and smaller tubers when growing potatoes in partial shade.
Can potatoes grow in the dark?
ANSWER: Yes, potatoes do sprout in the dark, but if you’re chitting potatoes (sprouting prior to planting), it’s best to do so in a light location that’s cool yet frost-free. Light is necessary for potatoes to grow healthy and strong.

How do you increase the yield of a potato?
The two key yield components of potato are tuber numbers per unit area, and tuber size or weight. Increased yields come from achieving the optimum tuber numbers, maintaining a green leaf canopy, and increasing tuber size and weight.
How many hours of sun do potatoes need?
6 hours
Plant potatoes in a sunny place with at least 6 hours of directly sunlight each day. The tubers need to grow in fertile, loose, well-drained soil; hard or compacted soil leads to misshapen tubers. Ideally, soil is slightly acid (pH 5.8 to 6.5) and the soil temperature is at least 45º to 55ºF (7° to 13°C).

Where do potatoes grow best?
full sun

Under what conditions do potatoes sprout the fastest?
Potatoes have a dormant period of 4–8 weeks after harvest before they will sprout. The warmer the conditions after dormancy ends, the quicker they will sprout. If you want potatoes to sprout during the dormant period, trick them by refrigerating for 16 days, then pre-sprouting them in the light.
Is it possible to grow potatoes indoors?

Should you cut off potato flowers?
To trim your edible potato plants, pinch off the blossoms as soon as they appear on the plant, or snip them off with shears. Blossoms are an indicator that the plant is mature and small tubers are formed. Removing the flowers removes the competition and fosters larger, healthier potatoes.
Can you dig potatoes before they have flowered?
Yes, you can dig potatoes before they have flowered. However, you will be much less likely to get a good harvest. Potatoes dug before the plant has begun to die off will not be at their full potential. If at all possible, wait until the plant has begun to die off to dig the potatoes.
