Cabbage moss is a cold season vegetable, suitable for cool climate. In most areas, red cabbage moss is usually planted in autumn and grows mature before winter comes. Generally speaking, the planting time of red cabbage moss is when the temperature begins to drop, so that it can be harvested before the frost comes.

However, the planting time will be affected by geographical location and climatic conditions. In warmer climate conditions, the planting time may be a little later, while in colder climate conditions, the planting time may be advanced. So the latest planting time should be determined according to the local climate and farming history.

In addition, the adoption of modern agricultural techniques, such as greenhouse planting and sunshade nets, can prolong the growing season of red cabbage moss and enable it to be planted in other seasons. These techniques can create an environment suitable for the growth of red cabbage moss, so that it is no longer limited by seasons. However, using these methods needs to consider factors such as cost and technical difficulty.
