above the soil surface, they are hilled up again. If there is the danger of a late frost, young tender potato plants can be completely covered with this soil to protect them from frost damage. Hilling up potatoes also helps keep weeds down around the potato root zone, so the potatoes are not competing for nutrients.
Do you cover leaves when hilling potatoes?
With the first hilling, I like to cover the vines up so that only the top leaves are exposed. This allows for a shallower second hilling done 2-3 weeks later with an additional 2-4 in of soil brought around the vines.
How many times should you cover potatoes?
Earthing up potatoes will increase the length of underground stems that will bear potatoes. This mounding can be repeated once or twice more at 2 – 3 week intervals to ensure the best crop, with the added benefit of smothering any competing weeds.
How often should I HILL my potatoes?
You can hill your potatoes 1-3 times per season/crop. Just loosen surrounding soil in the bed and pull up around the leaves and stems. Try to hill before the stems grow too long and start to flop over. You should pull between 2”-6” new soil up around the plants each time you hill.

Does hilling potatoes make a difference?
That said, hilling does tend to end up increasing the yield of potato plants because in addition to preventing potatoes from going green, it also controls weeds, improves drainage, and raises the temperature of the soil.
When should you start hilling potatoes?
When the plants are 6-8 inches tall, begin hilling the potatoes by gently mounding the soil from the center of your rows around the stems of the plant. Mound up the soil around the plant until just the top few leaves show above the soil.
How tall should potatoes be before hilling?

Should I let my potatoes flower?
Flowering just means that the vines are mature enough and have enough leaf area to start forming tubers. It doesn’t mean the tubers are ready to harvest. To toughen up your potatoes for storage before harvest, do not water them much after they flower. Let the vines die all the way back before you harvest them.
How tall should potato Hills be?
Potato plants should be “hilled” when the plants are 8 to 12 inches tall (Figure 7). Figure 7: When the plants are 8-12 inches tall they should be hilled to keep tubers covered and prevent greening. Mound the soil to a height of 3 to 6 inches and approximately 12 to 15 inches from the base of the plant.
Why do we Hill potatoes?
The main reason for hill potatoes is to increase yield. Potatoes form along the underground stem of the plant, and when you hill them, effectively lengthen the underground portion of the stem.
What is the best fertilizer for potatoes?
When planting, an NPK ratio of 15-15-15 is ideal. A month or two after they’ve been planted, potatoes need lots of nitrogen, so a fertilizer with an NPK of 34-0-0 is the best choice. An NPK of 12-12-17 or 14-7-21 is best for the last couple of months before harvest when the plants require more potassium.
Can I Hill potatoes with compost?
Potato Compost Hilling – Use finished compost to hill potato plants. The technique of hilling potatoes increases yields, keeps weeds down, and encourages potato plants to grow higher rather than spread out in the garden. This makes it easier to find and harvest potato tubers in the field.
How long can you leave potatoes in the ground?
However, the skin on the potato does harden and cure to make it stronger for storage. We recommend leaving the potatoes in the ground for about 2 weeks after the plants have died off.
Can you hill potatoes with grass clippings?
We have a big lawn, and eliminating the grass clippings had always been a problem. By using lawn clippings to mulch potatoes the potatoes grow remarkably fast, getting close to five feet tall before tipping over.
