When to plant potatoes?

The ideal time to plant potatoes depends on several factors, including local weather conditions, soil temperature, and the type of potato variety chosen. Generally, potatoes are planted in spring, after the last frost has passed and the soil is warm enough to encourage tuber germination.

Choose the right time: the end of frost

Potatoes are sensitive to low temperatures, and young plants are at risk of frost damage. Therefore, it is essential to wait until all risk of frost has passed before planting. In temperate regions, this is usually late March or early April, but in milder climates, planting can be brought forward by a few weeks. In colder regions, however, it is advisable to wait until mid- or late April.

Soil temperature for optimal germination

Soil temperature is a key factor when planting potatoes. Soil that is too cold will delay tuber germination, thus slowing plant growth. The ideal temperature is between 10 and 15°C. To check the temperature, a soil thermometer can be used. When the soil reaches this temperature, conditions are optimal for rapid germination and vigorous growth.

Traditional landmark: the flowering of lilacs

In many regions, the flowering of lilacs is a traditional signal indicating the right time to plant potatoes. This period often coincides with stable soil warming and the end of the last spring frosts. Observing lilacs in bloom can therefore provide a visual and practical clue for starting planting.

When to harvest potatoes?

The potato harvesting period varies depending on how early the variety is planted and what you intend to use it for. There are two main categories of potatoes: early potatoes, intended for quick consumption, and storage potatoes, which are harvested later for long-term storage.

Harvesting new potatoes (early)

New potatoes, or early potatoes, are harvested relatively early, about 80 to 110 days after planting. These varieties are picked just after the plants have flowered. They are particularly prized for their tender flesh and mild flavor, although their shelf life is limited.

• Signs of maturity : New potatoes are ready when the plants begin to flower. The tubers have a thin, delicate skin that peels easily.
• Storage instructions : These potatoes are fragile and should be eaten quickly, ideally within a few days of harvest. They can be stored for a few days in a cool, shady place.

Harvesting storage potatoes

Storage potatoes, intended to be stored for several months, require a longer growing period. They are harvested between 110 and 150 days after planting, usually in late summer or autumn.

• Signs of Maturity : Storage potatoes are ready when the foliage turns yellow but is not completely dried out. This change indicates that the tubers have reached their optimal size and are ready for extended harvest.
• Storage Preparation : After harvesting, let the potatoes dry in the shade for a few days to harden their skins. This step, called "curing," promotes better storage.
• Storage conditions : Once dried, store potatoes in a cool, dark, dry place at a temperature of around 5 to 10°C. Well-ventilated crates, crates, or silos are ideal for storing the tubers.

Tips for successful harvesting and storage

Harvesting potatoes at the right time and preparing them properly for storage is essential to extend their shelf life. Here are some practical tips to optimize this step.

• Use the right tools : To avoid damaging the tubers during harvesting, use a spade fork with a rounded tip. Lift the plants gently using a lever action.
• Monitor stock regularly : It is important to regularly check stored potatoes for mold or sprouting. Remove affected tubers immediately to avoid contamination.

When is the best time to plant potatoes?

The ideal time to plant potatoes depends on local conditions and soil temperature. Generally, it is recommended to plant in spring, when the risk of frost has passed and the soil has reached a stable temperature between 10 and 15°C, allowing for optimal germination. Potato wholesaler Patativerse advises you to carefully monitor weather conditions to optimize the success of your planting.

Why wait until the frost is over to plant potatoes?

Young potato plants are sensitive to frost, which can damage their shoots. Waiting until the frost is over ensures that the plants won't be exposed to excessively low temperatures, which encourages their growth from the moment they are planted. For advice tailored to your region, trust Patativerse, a potato wholesaler specializing in certified plants.

How do I know if the soil is warm enough for planting?

The ideal soil temperature for planting is between 10 and 15°C. To check, it is recommended to use a soil thermometer. Planting when the soil reaches this temperature allows for rapid germination and vigorous plant growth. Potato wholesaler Patativerse offers tips for measuring soil temperature and ensuring optimal planting.

When can I harvest early (new) potatoes?

New potatoes, intended for quick consumption, are harvested between 80 and 110 days after planting, often at the time of flowering. These varieties are prized for their tender flesh, but must be consumed within a few days of harvesting, as they have a short shelf life. Thanks to Patativerse, a potato wholesaler , discover the best practices for successful new potato harvests.

How do you know when storage potatoes are ready to harvest?

Storage potatoes are ready to harvest when the foliage begins to turn yellow, approximately 110 to 150 days after planting. This indicates that the tubers have reached maturity and are ready for extended storage. Patativerse, a potato wholesaler , supports you throughout all stages of the harvest to ensure the quality and sustainability of your tubers.

What are some tips for storing potatoes after harvesting?

For proper storage, first let the potatoes dry in the shade for a few days. Then, store them in a cool, dark, and dry place, ideally at a temperature of 5 to 10 °C. Use well-ventilated boxes or crates to avoid moisture and extend their shelf life. Patativerse, a potato wholesaler , recommends these techniques for optimal storage.

How to avoid damaging potatoes during harvesting?

For a smooth harvest, use a rounded-tipped spade fork and carefully lift the plants with a lever action. This reduces the risk of puncturing or damaging the tubers, which is important for good storage. Follow the advice of Patativerse, a potato wholesaler , to ensure a quality harvest.
