How to: Can You Grow Potatoes in Clay Soil?

Potatoes thrive in well-drained, soft soils which are rich in natural material. Soil which is excessively sandy, rugged, or clay isn’t nice for potatoes.” This is correct, but ideal circumstances will not always exist.

During a survey, it was discovered that references to potatoes are used to snap up clay topsoil in a day, mainly in places previously occupied with grass. The method of hilling up land and natural components around growing crops, we presume, aids in soil construction.

How to Plant Potatoes?

Potatoes are a beneficial plant to sprout in the vegetable patch; here’s how to maximize one’s yield. Nothing compares to the flavor of newly excavated potatoes, and rising your own can not be simpler. If you begin planning, you might be going to eat newly dug veggies all season and early fall, and if you’re witty, you might even get a\ winter to produce to brag about.

The potato season starts in earnest with ‘chitting’ (growing) the initial cultivars in January in relatively warm locations and during February in cold regions, approximately 6 weeks before sowing them outside. Simply hold them on the extreme in an egg plate with ‘eyes’ or tiny dents with blooms in the skin erect, and put them in a vibrant, chilly, frost-free location.

Can You Grow Potatoes in Clay Soil?

Thick soils are sometimes labeled as tough; but, when cultivated carefully, they may be just as fruitful as anything else, with no additional labor. Clay holds water and mineral nutrients higher than just about any other type of soil, making it ideal for vegan organic farming.

In fact, not all clay soils are exactly alike, some of which are very open than others, and some appear to be solely appropriate for making bricks. Nevertheless, almost all clays can react to the basic procedures.

The quantity of sand, clay, or loam existing in a specific soil specimen can be estimated by blending a small amount in water inside a glass and letting it rest; the three components will detach into layer upon layer, but the enhancement techniques are usually the same regardless of the type of the specific soil.

Clay soil is typically quite thick and densely packed. Because potato tubers develop underneath, clay makes it difficult for tubers to develop. Add extra composting or old manure to the clay soil to enhance it for potato cultivation.

This will help the ground drain properly, loosen it up, and provide minerals. Note that sand can not be used to soften clay soil. As a consequence, the soil would be extremely hard and tough to deal with!

If the soil contains loam (not clay), although maybe not as open as you would like, you may add just a little sand to that though. Potatoes, radishes, or other “root” plants like lighter earth, which enables them to develop without breaking against tight clumps of topsoil.

If your ground is excessively sandy, then that will drain extremely quickly. This might cause a water shortage for any crops you attempt to cultivate, even potatoes. If the ground does not keep its structure and washes up soon, it is most likely sandy soil.

Soil pH Level

Clay soils nearly always have a greater pH, which is inherently alkaline and therefore can vary between 8.0 – 10.0. This is a bit too much for what we’re looking for while producing potatoes. The very first step is to determine the soil ph. so that we know precisely what we’re working with.

Then we may start lowering the pH towards 5.5 to 6.0 – you might rarely decrease the pH over more than 1 to 2 points in a single planting season, however it is usually best to attempt than do nothing.

Wood ash, vinegar, coffee, iron sulfate, and even basic sulfur are examples of pH-lowering additions. Take caution to add them to the ground in little amounts so that you don’t overdo it.

We would recommend starting this practice in the preceding fall to give the remedies time to act. Add a small amount, integrate it, and afterward measure. Unless you’d want to read about reducing the pH of the soil, there are posts about that too.

Fertilizer restores any minerals deficient in the ground. When spread at the ratio of 11/2 pounds every 50 square feet of beds before planting, a 5-10-5 and 10-10-5 combination gives plenty of nourishment. Potatoes primarily need nitrogen, phosphorus, and potash abbreviated N-P-K.

The amount of nitrogen is the very first figure on the fertilizer label, preceded by the amounts of p and k. The remaining elements are provided by the second treatment of a pound of fertilizer every 50-foot line once the potatoes attain a size of 4 to 6 inches. Spread this fertilizer on the ground approximately 6 inches distant from your plants and quickly water it in to allow it to soak in.

Water Content of the Soil

Appropriate soil moisture promotes healthy development, while excessive moisture could lead to rot issues. Although soil quality that has been modified with manure or organic material holds moisture efficiently, it can nevertheless dry out in scorching or dry conditions.

Thorough watering keeps the ground from running dry too rapidly, so offer about One inch of water every week, allowing it to sink at least every six inches into the ground. Topping the ground with 2-4 inches of straw mulch helps to maintain water even while shielding potatoes that grow close to the ground surface against sun damage, which might kill them.

Planting Season

Potatoes could be cultivated throughout the year. They seem to be winter tender, requiring 60 to 90 days of cold-free to mature for effective production. If you are going to grow in a frost-prone area during the winter, include a shield of plastic or light color fabric connected to wagers or star picket lines to enable airflow.

It can be excluded when there is no threat of ice and snow (to enable rain to enter), though – and keep in mind to replace it if some other cold spell is predicted. The majority of people prefer to plant in the fall (March/April) since the ground is heated and development is quick.

If you reside in a frost-free area, you may plant them any moment from springtime to near summer – although they do not produce well during the warmer seasons and are more susceptible to pests and illnesses. Sow in frost-prone locations in early spring, right before the last anticipated frost.

Is it possible to grow potatoes from seeds?

Potatoes can be propagated from seed in concept, but only farmers do so in practice. Sowing potato seeds have no benefits for the home grower. For one reason, there is a good chance that cultivars were intermingled during pollination.

This suggests that the following generations from seeds will most likely be a hybrid rather than purebred. Secondly, tubers develop significantly more slowly in seeds.

A year after these seeds are sown in February, the produced tubers are relatively tiny and give little output. Only if the crop from the previous year is seeded out the next spring is the output comparable.

How Much Time Does It Require to Raise Potatoes?

Based on the cultivar, potatoes are prepared to harvest for around 70 to 90 days. Whenever the greenery starts to die away, the potatoes are harvestable.

Nevertheless, “baby” tubers can be harvested 2 to 3 weeks after crops have finished blooming. Dig cautiously all-around crop, collecting just a few potatoes that you want to consume right away.

Potato Harvesting

Potatoes for storage must not be unearthed for 2 to 3 weeks after the greenery has died down. Sit tight for just a few days for a dry season before harvesting. Pick potatoes gently with a strong gardening fork.

Let the potatoes rest in the growing medium for 2 or 3 days after picking. This procedure permits the potatoes to begin curing, which will help them survive further in storage.

If the weather report predicts rain, you may cure the tubers in a sheltered space such as a shed or enclosed porch. The tubers will have to cure lasting up to 2 weeks in a clean, cold, dark environment (45 – 60 ° F).

Some top tips:

  • Grow inside an old bag, half-wine barrels, or aging compost pile.
  • Potatoes would shrink in size in a smaller area.
  • Further fertilizer is usually unnecessary if the ground has been properly prepared. If you believe the development isn’t as rich as it ought to be, you may feed the tips a small feeding of seaweed and comfrey tea.
  • Grow potatoes in a sunlit location, and yet never leave the tubers to light.
  • Plants that make decent companions include horseradish, beans, corn, marigolds, peas, nasturtiums, cabbages, and parsnip.
  • Cucumber, sunflower, tomatoes, pumpkin, onions, and rosemary are all poor companion crops.


When we all wish we had perfect soil for growing potatoes, the fact is that not everybody does. This will not prevent us from growing potatoes; rather, we must understand how to properly prepare and maximize our soil before sowing. The advantage of producing potatoes on clay is that you’ll have greatly improved the ground for the following harvest!
