Soil preparation for potatoes is essential before you proceed with planting. The best time to do this is just as the last frost has passed and the ground starts to warm up. We’ve already talked about how to grow potatoes. Today, in this post I’m going to discuss how to prepare the soil for growing potatoes.

What Soil Is Best for Potatoes?

You can plant potatoes in just about any well-drained soil. They only hate soggy soil. As most of the growth occurs underground, the ideal soil for growing potatoes is loose sandy loamy soil with a pH range of 5.5 to 6.5 (slightly acidic soil), where they can expand easily.

If you have this kind of soil you do not need to do anything, but if your soil is heavy, compacted, clay soil that is not loose enough or not ideal for growing potatoes, don’t be disheartened. You can improve your soil very easily.

Here are two ways to improve your potato growing soil:

  • By adding well-rotted compost to the soil.
  • By planting a cover crop.

Adding Organic Matter to The Soil:

One of the easiest ways to loosen heavy soil is to add organic matter to the soil. Organic matters like leaves, peat moss, hay, well-rotted compost, etc. open up the soil and let air, water, and nutrients circulate easily.

Add these organic materials to the soil before the potato growing season starts.

Planting Cover Crops:

Another simple way to improve the quality of your potato growing soil is to grow cover crops on the soil prior to planting potatoes. These cover crops will build up organic matter in the soil. Once you harvest the cover crop, plow the plants and wait for two months before planting potatoes.

A cover crop like annual ryegrass will decompose and will add moisture-holding organic matter and nutrients into the soil.

How To Prepare Soil Beds For Potatoes:

Preparing a proper soil bed is very important for growing potatoes. If the bed is not made properly it can result in soil compaction, lack of aeration in potato roots, and inferior quality potatoes.

The first rule for preparing a potato bed is never to plant potatoes in the area where any other plant from the Solanaceae family has been planted earlier. It can increase the infection from pathogens. The best area for planting potatoes is the area where a legume plant has been planted earlier.

Use nutrient-rich, loose sandy loamy soil with a pH of 5.5 to 6.5. Add 3-4 inches of well-rotted compost and mix it with the existing soil. Loosen the soil up to a depth of 12 inches.

Turn the soil several times so that there are no lumps get formed. Remove any stone, or debris from the soil. Make sure the soil drains pretty well. To increase the drainage of the soil you can mix coco coir, perlite, etc with the soil.

Planting Potatoes in The Soil:

Once your potato seedbed preparation is complete, you can start planting the sprouted seed potatoes. Although you can use seed potatoes directly, sprouting the potatoes before planting can help reduce the overall growing time. Here is how you can easily sprout seed potatoes.

Plan your planting accordingly so that the soil temperature should not drop below 50 deg F when you plant potatoes.

When preparing the soil for your potatoes remember that it is important to loosen up the hard clay. And if you are like me, then there is nothing better than digging your hands into a pile of rich loamy soil.

I hope this post was helpful in understanding what is the best soil for growing potatoes and how easily you can prepare this without investing too much money.
