These dates are only estimates, it is best to check the local weather a few days before planting to be sure of the local climate. There are years when the frost comes early and others when frost is delayed.
Most important of all, potatoes do not tolerate frost and require soil temperatures of at least 50 °F (10 °C). So before planting your potatoes make sure of the temperatures, if you want to plant potatoes earlier you can plant potatoes in bags. Learn more about how to plant potatoes in bags.
- These grow bags are made of sturdy material, allow roots to breathe and grow healthier, and make plants have really thick stems and healthy roots. You can also observe the growth of roots and seeds from the flap.
- Ventilated holes on the bottom and side improve aeration, provide better drainage and air flow. But importantly air prunes the roots and helps branch root system out.

Planting Potatoes in Oklahoma
Not only is the temperature important for planting potatoes in Oklahoma, but also the soil and the irrigation you give the potatoes to develop properly. Below I will tell you what is the best soil for potatoes, how to water them, and several tips for your potatoes to develop properly.
According to the University of Oklahoma, potatoes grow well in a wide variety of soils. Potatoes can grow in soils with a pH between 5 and 6.8, but the best pH to avoid certain potato diseases is between 5 and 5.5. You can easily measure the pH of the soil with pH strips or a digital pH tester. I recommend our article about how to measure soil pH.
Potatoes grow best in loose, well-drained soils rich in organic matter. Compost or well-decomposed manure should be added to the soil to improve its structure and fertility. It is also important to loosen the soil to a depth of about 12” (30 cm) for the potatoes to develop better. Avoid planting potatoes in waterlogged soil or soil with stagnant water, as this will cause the potato plant to rot.
Watering potatoes is important for their growth and development. It is important to keep the soil constantly moist, but not waterlogged, during the potato growing season. Water the plants once or twice a week, depending on the weather and soil conditions. It is important to prevent the soil from drying out completely, as this can cause the potatoes to become too small or misshapen.
When watering potatoes in Oklahoma, it is best to use a soaker hose or drip irrigation system, as these methods help conserve water. Also, using these watering methods prevents the leaves and stems of the potatoes from getting wet, which can lead to fungal diseases. Water potatoes early in the day, so that the foliage has time to dry out before nightfall.
I recommend mulching around potato plants to help retain moisture and eliminate weeds. You can use any type of mulch for the potato plant.
