What should be paid attention to in the maintenance of Xi Yinhua?

Xi Yinhua is famous for its red paulownia grass. Flowers are solitary in the axils of leaves, scarlet, and bloom in summer. Common varieties are emerald queen, leaves are dark green, midvein silver-white; copper-green shade flowers, leaves are copper-green, leaf edges are light red; chocolate flowers, main veins silver-white and silver-light shade flowers, flowers and leaves like shade flowers and so on.

The main results are as follows: (1) the root system of shade-loving flower is shallow, which is mostly distributed on the surface of loose medium, so it is appropriate to choose shallow pot when potted. The basin soil can be mixed with loose and fertile rotten leaf soil or peat soil plus 1 beat 3 perlite or 1 pound 4 river sand, plus a small amount of aggregate as base fertilizer.

(2) change the basin every spring. Combined with changing the basin for proper pruning, in order to promote branching and more flowering. In the peak growing season (from April to September), thin cake fertilizer and water can be applied once every 10 to 15 days, and liquid fertilizer dominated by phosphate fertilizer can be applied at the end of May to make the flowers bright. When fertilizing, you should be careful not to splash the fertilizer on the leaves, otherwise it will easily lead to leaf rot. Except for the need to control watering in winter, it is necessary to keep the basin soil moist in other seasons, but avoid stagnant water in the basin soil. Soil drainage is poor, too much watering, easy to make short stems near the surface, due to long-term impregnation in the water and cause rot, or root rot. If there are stagnant water droplets on the leaf surface, it is easy to produce sunburn disease after direct exposure to strong light.

(3) controlling temperature and light. Shade-loving flowers like high air humidity, which is conducive to growth and flowering, so it is advisable to spray the leaves frequently in summer to increase air humidity. You can also use a large shallow basin filled with small pebbles, inject clear water, and put the flowerpot on the pebbles to keep the plant in a locally humid environment.

Like warm, humid and semi-overcast environment, afraid of direct light. It can be cultivated indoors with bright scattered light at ordinary times, and in a sunny place in winter. The room temperature is kept above 16 degrees Celsius during the winter.
