When will potatoes be planted in the latest autumn?

Planting potatoes in autumn, at what time to sow, what kind of temperature conditions are needed, what kind of environmental conditions are needed. When the sowing time is suitable, when sowing, will not affect the subsequent growth. This is the premise of autumn potato key content, we will now learn about the autumn sowing time content.

1, planting time

Autumn planting time is generally between late August and early September, as long as the soil temperature drops below 25 degrees can be sown, tubers above 25 degrees will stop growing. Local differences, some areas in August ground temperature has been below 25 degrees, some or relatively high. Look specifically at temperature. Sowing time should ensure that there is two months of growth time between emergence and first frost.

2. Temperature requirements

Potatoes like to grow in cold environments and grow at low temperatures. Generally, they stop growing underground tubers after temperatures exceed 25 degrees Celsius. The most suitable temperature for tuber growth is 15 degrees to 18 degrees Celsius. Above ground stems and leaves are suitable for growth between 15 and 25 degrees. Generally above 38 degrees, it will stop growing stems and leaves. So it's best to sow at a temperature of about 20 degrees.

3. Soil conditions

The soil does not have to be too fertile, but it must not be sticky and hard. It must be soft, loose and dry. The sand is very suitable for planting. Soil pH requirements are not strict, can be appropriate partial some, as long as it is not extreme pH. Family pot planting, you can choose to prepare soil, use sawdust, chaff and the like decomposed mixed soil, but also can add river sand, just humus and the like to plant.

4. Select varieties

Autumn planting potatoes to choose a short growth period of varieties, preferably 3 to 4 months can be harvested, because winter cold low temperature, will certainly affect the growth of potatoes. The whole potato grows better as a seed potato, but it is easy to rot, infect diseases and germinate badly. It is generally best to have 30 grams of potatoes for seed potatoes.

Potatoes are planted in autumn, usually from August to September, but temperature conditions dominate. As long as the conditions are met after planting can grow well. It is also important to grasp the appropriate sowing time and ensure sufficient growth time.
