The production of safflower tree is basically the same as that of other miscellaneous trees. After the billet pile of Carthamus tinctorius survived completely, it should be observed and studied repeatedly according to the characteristics of the stump, conceived and modeled, and then made.

To cultivate Carthamus tinctorius, it is best to use 50% loose mountain yellow mud, 30% coarse river sand, 20% pond mud or paddy field mud. (less alkaline in pond mud or field mud is better)

In addition, according to the safflower tree transplanted at different times, the branches should be trimmed properly, less in spring and more at other times, so as to avoid evaporation of water in branches and leaves, resulting in water loss. Cover the tree stump and leaves properly when the sun is strong, and spray water on the stump and leaves according to the weather and humidity, so as to keep the trunk and leaves moist after transplanting.

Plant or change pots before sprouting in spring. It can be planted in the open air to survive the winter in the south of the Yangtze River. Pot planting is suitable for overwintering in the north. The land should be planted in a place with sufficient sunlight and good drainage, requiring the soil to be loose and fertile. Pot culture should choose rotten leaf soil, garden soil and river sand mixed culture soil, it is best to add appropriate amount of mature organic fertilizer or compound fertilizer. Planted with 1-2-year-old seedlings. Change the basin once every 2 years. Water after planting and keep in a half-shaded place.

2. Light and temperature

The suitable growth temperature is 20-28 ℃, and it should be cultured under full light in spring and autumn, which is beneficial to flowering and make the leaf color more beautiful. Summer should be shaded or placed in a sparse shade under trees to avoid strong direct sunlight. It should be placed in a bright place indoors, preferably with a certain amount of light every day. Move into the sunny place indoors in winter.

4. Shaping and pruning

It should be reshaped and pruned before sprouting in spring, and the dead and overdense branches should be cut off. Pick buds at the right time during the growing period, promote the germination of new branches and blossom more, but can not be pruned in late autumn, so as to avoid cold damage to the new shoots after pruning, resulting in fallen leaves.

Ji Mu bonsai has less soil, shallow roots, poor cold resistance, easy to freeze and dry up, and even die. Therefore, winter is not suitable for overwintering outdoors, should be placed indoors, and pay attention to ventilation, room temperature to maintain more than 5 degrees; when the room temperature is more than 25 degrees, you can open the window to avoid excessive growth caused by high temperature, when the room temperature is less than 5 degrees, plastic bags can be covered (when the room temperature is higher than 5 degrees, plastic bags should be removed immediately). When the room temperature is less than 0 degrees, heating methods such as hot water should be used to protect the bonsai from overwintering.
