The suitable temperature for growth is 20-30℃. Avoid cold and wet, in too wet environments. The blade is easy to spot soiled frozen spots.

Guiana Chestnut propagation method

The guiana chestnut propagation can be divided into two methods: sowing and cutting. 

Seeding method

Because seed reproduction has the characteristics of neat emergence, straight root and smooth emergence, easy to braid and easy to grow out of round and lovely "radish head", sowing reproduction is a commonly used method of reproduction. Seeds should be picked and sown as they mature in autumn. When the outer skin of the fruit is yellow or dry, it can be harvested. After the fruit is collected, the shell is cracked and the seeds are planted in the river sand or Garden mud. The sowing depth is 2-3 cm, and the temperature is controlled within the range of 20-30℃.3 to 5 days after sowing, germination, 20-30 days can be planted in the field or potted. 

Cuttage

Compared with sowing seedlings, cutting seedlings have the defects of no expansion or only slight expansion of the stem head. Seedling dry is not beautiful, so this method is rarely used. Cuttage propagation in the south is generally from March to October for a higher survival rate. Choose robust, no pests and diseases of the plant top tip for cuttings, cuttings length of 10-12 cm, remove the lower leaves, large leaves cut half, at the same time to cut cuttings oblique, in order to expand the hair root area of cuttings. Then the "root sun" rooting agent 300 times of liquid and yellow mud mixed into mud, cut cuttings dipped in mud, until the mud dry into the seedling bed. In the temperature range of 20-25℃, about 12-15 days after implantation can be transplanted to the pot. After cuttings are finished, water should be poured in time, so that cuttings and soil are closely combined, otherwise the cuttings are easy to lose water and dry up, affecting the survival. For normal management, the soil should be kept moist or sprayed daily for 3-5 minutes. Cuttings should be timely covered after completion, with 90% shading net covering in summer, 60-70% shading net covering can be used in spring and autumn. The optimum temperature of cutting rooting is 20-25℃, and the temperature below 15℃ is not suitable for cutting propagation.
