When to Plant Potatoes in Alaska: A Guide for Gardeners

When to Plant Potatoes in Alaska

Potatoes are a delicious and versatile root vegetable that can be enjoyed in a variety of ways. They are also a relatively easy crop to grow, but it is important to plant them at the right time in order to ensure a successful harvest.

In Alaska, the best time to plant potatoes is in early June, after the last frost date. This will give the plants plenty of time to grow and mature before the first frost of fall. However, if you live in a warmer climate, you may be able to plant potatoes as early as April.

When planting potatoes, it is important to choose a sunny spot with well-drained soil. The ideal soil pH for potatoes is between 5.5 and 6.5. You will also need to provide the plants with plenty of water, especially during dry spells.

Potatoes can be grown in containers or in the ground. If you are planting them in containers, make sure the container is at least 12 inches deep and has drainage holes. If you are planting them in the ground, dig a trench about 12 inches deep and 3 feet wide.

To plant the potatoes, place them about 12 inches apart in the trench. Cover the potatoes with soil and water well. The potatoes will begin to sprout in about two weeks.

Once the plants have sprouted, you will need to thin them so that they are about 12 inches apart. You will also need to keep the weeds under control.

Potatoes are ready to harvest when the skins are tough and the flesh is firm. To harvest the potatoes, dig them up carefully so as not to damage the skins. Store the potatoes in a cool, dry place.

With a little care, you can enjoy fresh potatoes from your own garden all summer long.
