Mulch thickly with straw or shredded leaves to keep the soil cool, weed-free, and to cover any tubers that grow close to the surface to prevent them from turning green.

Potato plants need ‘earthing up’ as they grow, to protect early shoots from frost damage and ensure the developing potatoes aren’t exposed to light, which turns them green and poisonous. It’s a simple process – once the stems are about 23cm (9in) tall, draw soil up around them, creating a ridge about 15cm (6in) high.
When should I cover my potatoes with a straw?
When you grow potatoes in straw, you’ll see the sprouts quickly. Once they have grown 4 to 6 inches (10-15 cm.), cover them with more straw until only an inch (2.5 cm.) of the new growth shows through, then let the plants grow another 4 to 6 inches (10 to 15 cm.).

What is the best material to cover plants from frost?

Can I cover plants with garbage bags for one night?
Yes – if you secure the plant properly. Garbage bags work to cover plants and protect from frost, but they must not be allowed to touch the plant’s surface. Use stakes and supports to create a tent-like structure over the plant, which will retain warm air. Make sure the trash bag goes all the way to the ground.
What can I use to earth up potatoes?
On light soil, mix in well-rotted garden or bagged compost to earth up the potato plants. This helps conserve moisture which swells the tubers.
Should I remove 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.
How often should potatoes be watered?

When should I stop watering my potato plants?
Stop watering your potato plants about 2-3 weeks before harvest, or when you first see the foliage on the plants starting to turn yellow. Make sure to harvest your potatoes on a dry day when the soil is dry—harvesting potatoes when wet or damp can cause the potatoes to rot more easily in storage.
How do you increase the yield of potatoes?
When the potatoes have sprouted and grown foliage about 8” tall, you should begin “hilling” the plants by mounding the fluffy soil on either side of the trenches up around the stems of the plants. As long as there is some foliage sticking out they’ll keep growing, and the more you hill, the more potatoes you’ll get.

Can you bury potatoes too deep?
But, planting the seed potatoes too deeply from the start can cause them to rot before they sprout. At the very least, it makes harvesting very difficult at the end of the growing season because the potatoes are buried so deeply.
