What should I do if the mirror grass withers?

Mirror grass is an evergreen succulent herb of Urticaceae, with a plant height of 35-40 cm, stout, fleshy and brown stems. The old stems are often lignified, with dark brown stipules and leaf scars on the nodes. The leaves are green, nearly round, 5-8 cm in diameter, and the meat is shiny. The young leaves are slightly rolled in and gradually unfolded, and the petiole is shield-shaped and is born in the upper part of the leaf center.

Native to the northwest of Yunnan Province, China, it likes warm, humid and moderately shaded environment. It can grow well in a well-lit room and is relatively cold-resistant, but it will freeze below 0℃, which requires loam to be rich in humus, loose and fertile, and well drained. Propagation can be carried out by branching, cutting and sowing.

The flowering period of mirror grass is spring, that is to say, flower buds are differentiated under short sunshine. Under normal circumstances, plants affect the height growth of plants during flower bud differentiation. The reason why your mirror grass doesn't grow well is precisely because it grows thick in spring and coincides with the condition of short sunshine, so it only blooms and tillers, while the high growth of plants is slow. This requires applying more nitrogen fertilizer in spring and less phosphorus and potassium fertilizer. It is best to pick its flowers and it will be the same in the future.

It can also be placed in the middle of many flowers, making use of plants' phototaxis and instinct for space to make plants grow tall quickly.

Supplement: Nitrogen fertilizers commonly used in daily life include urea, ammonium sulfate and ammonium bicarbonate. Generally, there is a sign on the package of chemical fertilizer: n stands for nitrogen fertilizer. The greater the N content, the higher the nitrogen content. Compound fertilizer is generally marked on the packaging.
