When do you plant cucumbers and beans in the open air in spring?

If it is in the south, if the temperature can be stabilized at around 20 degrees during the day, it can naturally be planted in the open space. In the north, it is expected that these two vegetables will be planted in the open field around Tomb-Sweeping Day. When planting cucumber, the suitable temperature for cucumber growth is generally around 15 ~ 35℃, and the suitable temperature for seed germination is generally around 1 1 ~ 15℃. When the temperature of vegetable field is about 25 ~ 28℃, the most suitable temperature for fruit growth is to plant northern beans instead of raising seedlings in advance.

There is a saying in the countryside that it will be clear before February and clear after March, which means the time of sowing. If Tomb-Sweeping Day appears in February of the lunar calendar, it will be later to plant beans outside than in Tomb-Sweeping Day. The time for planting beans (green beans) in the open air in spring is after the vernal equinox, that is, in late March, and the natural temperature reaches 12℃-26℃.

Beans, also known as cowpeas or beans. Cowpea likes warm and is afraid of cold. Cowpea seeds germinate at about 25℃. Farmers generally choose to plant cowpeas directly. In order to keep the soil temperature, they can cover it with plastic film, and then tear the hole to expose the seedlings after the cowpea sprouts. Cucumber and beans adapt to the warm climate, and the growth will be affected when the temperature is lower than 15 degrees. Cucumber and beans belong to lianas, and they like warm and cold. In order to keep the soil moisture temperature during the growth process, 25-35 degrees is the most suitable growth temperature.

Because of the high latitude in the north, the temperature rises slowly, and now the temperature is still below 10℃. The farther north, the lower the temperature. It is not suitable for planting cucumbers and beans in the open air, and it can only be planted in the open air in the north at least in April. Generally, the suitable growth temperature of cucumber is about 25 degrees, and it is not resistant to low temperature. If the temperature is low, it will grow slowly, so you can't plant it early, because it's too cold to freeze to death without waiting too long.
