When is the most suitable time to plant potatoes in autumn

When planting potatoes in autumn, at what time should you sow them, what temperature conditions are needed, and what environmental conditions are needed. What is the suitable sowing time, and when should you sow so that later growth is not affected. This is the key prerequisite content for autumn-sown potatoes, and now let us learn together about the timing of autumn sowing.

1. Planting time

Autumn planting time is generally between late August and early September. As long as the soil temperature drops below 25°C, you can sow; tubers stop growing above 25°C. Due to regional differences, in some areas the soil temperature in August is already below 25°C, while in others it is still relatively high. Look at the temperature specifically. The sowing time must ensure there are two months of growth time between emergence and the first frost.

2. Temperature requirements

Potatoes like to grow in a cool environment and grow at low temperatures. Generally, after the temperature exceeds 25°C, the underground tubers stop growing. The most suitable temperature for tuber growth is 15°C to 18°C. The aboveground stems and leaves are suitable for growing between 15°C and 25°C. Generally, above 38°C, the stems and leaves stop growing. So the best sowing time temperature is around 20°C.

3. Soil conditions

The soil does not need to be too fertile, but it absolutely must not be clayey or compacted. It must be soft, loose and dry; sandy soil is very suitable for planting. The soil pH requirement is not strict, and it can be slightly off, as long as it is not extremely acidic or alkaline. For household pot planting, you can choose to mix your own soil, using rotted wood shavings, rice husks and the like mixed with soil, and you can also add river sand or just humus soil and the like for planting.

4. Choosing varieties

For autumn potato planting, choose varieties with a short growing period, preferably ones that can be harvested in 3 to 4 months, because the severe cold and low temperatures of winter will definitely affect potato growth. Growing whole potatoes as seed potatoes works better; cutting them up as seed potatoes makes them prone to rotting, disease infection and poor sprouting. Generally, it is best to use potatoes about 30 grams in size as seed potatoes.

For autumn potato planting, the time is generally from August to September, but the main factor affecting the time is temperature conditions. Only when the conditions are met can planting grow well. Grasping the suitable sowing period and ensuring sufficient growth time are also very important.
