Nine-dead grass is a mythical name, which is usually not specified in literary creation. In real life, the nine-dead regrowth refers to Selaginella, a plant that grows on rocks and soil cracks in the mountains.
Selaginella is called "nine dead resurrection grass" mainly because of its strong vitality. In the dry season, its branches and leaves turn yellow and shrink into a ball, looking as if they were dead and lifeless.
Once it rains, Selaginella leaves will slowly open and turn from yellow to green, as if coming back to life.
This magical change of Selaginella Selaginella is mainly due to its special leaf structure, which has strong drought resistance and dehydration resistance, so it can catch fire with a little fire, just like withering in drought, but it can recover quickly when it meets water.
Because of the particularity of Selaginella, a few years ago, many people began to raise Selaginella. Although it is called "resurrection grass", it seems to have the ability of "resurrection", but it is not easy to raise it ~
Selaginella protection
When buying Selaginella, you can directly buy green ones that have been cultivated for some time. If you buy it dry, it depends on whether the root system at the bottom is sound. If the roots are gone, it is difficult to revive at home.
After the sun-dried Selaginella is bought home, soak it in clear water for more than 12 hours, let it "revive" first, and then plant it in a pot after the leaves turn green.
Selaginella can be planted with sandy soil, absorbent stone, volcanic rock, cinder soil, etc. Water moss, humus soil, coconut bran soil and nutrient soil can also be planted. Its root system is very shallow, and it doesn't need much plant materials, just a little flowerpot.
Selaginella likes humid environment and is not suitable for dry place. Try to put it in a cool and ventilated place at home, and spray water around it for humidification. Once leaves are short of water, they will dry.
Because Selaginella needs high humidity, it is necessary to keep ventilation, so that there will be no more water to suffocate the roots or breed bacteria.
Some flower friends say that it is still dry after spraying water, or it is easy to forget to spray water at ordinary times. Selaginella can be planted in a water tank, and turtles, small fish and shrimps can be raised at home, only the leaves are exposed. There is enough humidity in the tank.
If there are no fish and turtles at home, you can also put the dried Selaginella in the bathroom. A humid and cool environment is conducive to recovery.
There are professional gardeners who plant Selaginella in clay pots, put a big pot rack under it and pour it when watering. Excess water is put in the basin, forming a moist local microenvironment, which is especially suitable for the growth of Selaginella.
If you don't want to plant Selaginella, you can also put it in a corner of your home, let it dry up and go to sleep slowly. Be careful not to put it directly in the sun every day (except in wet southwest or seaside areas) to avoid high-intensity and long-term dehydration.
When you want it to recover, you can replenish it with enough water to make it green.
