Rainbow arrowroot is a perennial herb flower, and the purple patches on the back of its leaves are as beautiful as rainbows, hence the name. It has high ornamental value and is suitable to be placed as an ornament at home. In addition, it also has the meaning of dreams, love needs courage and so on. It is perfect for friends who are fighting for their dreams and love. Today, I will tell you how to cultivate beautiful rainbow arrows.

First, choose soil.

Rainbow arrowroot likes loose and fertile acid soil with good drainage performance. Flower soil can be prepared with 5 parts humus soil, 1 part compost and 4 parts river sand or sawdust, and the optimum pH value is in the range of 5.5 ~ 7.2. The soil prepared in this way can well meet the nutrients needed for the growth of rainbow arrowroot.

Second, water and fertilizer management.

Rainbow arrowroot likes humidity. When the temperature is high in summer and autumn, attention should be paid to keeping the basin soil moist. In addition to watering once a day, you can also spray water from time to time to prevent the tip from burning. Nitrogen fertilizer should be applied once a week during the growth period of rainbow arrowroot, or it can be changed into decomposed and diluted cake fertilizer water from time to time to avoid single fertilization. There is no need to fertilize when the temperature is low in winter.

Three. Light and temperature

Rainbow arrowroot likes light, but it should avoid strong light, otherwise the leaves may be old and withered and easily damaged. Under normal circumstances, you can put the lamp outdoors to receive the sunshine for half a day, which will not be dazzling. In winter, the temperature should be kept above 10℃, so as to ensure the safety of rainbow arrowroot in winter.
