The solution to the rotting Root of Gentleman

When summer comes, the flower lovers who breed magnolia should sigh again, "the season for rotting roots of magnolia has come!" Dear, do you know why magnolia is easy to rot in summer? The best growth temperature of Cymbidium is 5 ℃-25 ℃. In the summer of high temperature and humidity, it is easy to rot if it is not properly maintained. So how should we deal with the rotten roots of a gentleman? Let's read on and learn more about it.

The way to deal with the rotten roots of gentleman orchids:

If the flower friend finds that his rotten root is rotten, knock the rotten root out of the basin, remove the soil, cut off the rotten root, wash the root with clean water, and then smear the rotten root with 5 ‰ potassium permanganate aqueous solution (you can also disinfect it in other ways, such as plant ash), then wrap all the leaves in newspaper or white paper, expose the root, and place the root in the sun for half an hour.

After treatment, if only a few roots of Cymbidium are rotten, they can be planted directly in the sterilized nutritious soil, less watering in half a month, and can resume growth after a month. If most of the roots rot, they should be planted in a basin filled with fine sand and placed in a cool place to promote them to sprout new roots. After about a month and a half, the new root grows, and the nutritious soil can be replaced for normal maintenance and management. it is also possible to use other media, such as perlite and water moss.

In summer, the maintenance of Cymbidium should not only take measures such as shading, ventilation and cooling, but also control plant growth, such as no fertilization or less nitrogen fertilizer, control watering, no dry and no watering.

Maintenance of Magnolia:

1. Use soil. Cymbidium prefers loose and fertile neutral or weakly acidic humus soil, which can be mixed with 65% humus soil, 20% net sand and 15% fine grass ash. Or the soil in the stone crevice dug in the mountain, the pine needle soil under the pine tree, or the retting soil made of larch leaves, can also be decaying leaves or grass foams over a long period of time. The general principle is that the soil is rich in nutrients, and watering is the best.

2. Watering. Gentleman orchid likes neutral water, clean and pollution-free tap water, well water, river water and so on can be used for watering, but because the water temperature of fresh tap water and well water is lower than the soil temperature and contains some impurities, it should be placed for 1-2 days before use. As for watering, there is also a lot of fastidiousness. The best way for a gentleman's orchid seedling is to spray it with a sprinkler. Spray the nozzle up to the leaf, which has the advantage of not only watering the flowers, but also washing dust, leaving fog beads on the leaf surface to ensure a certain humidity on the leaf surface, and water evaporation in the sun can reduce the leaf surface temperature and prevent sunburn.

But the flowering magnolia can not be watered by sprinkler irrigation to waterproof into the leaf sheath resulting in rotten heart, for the flowering magnolia can only be watered into the basin. Then when and how much water is appropriate? This mainly depends on the ambient temperature of the magnolia. The general watering principle is "see wet see dry, do not dry do not water, dry thoroughly". Watering thoroughly is to keep all the roots of the orchid in the same humidity. Judging whether the water is thoroughly watered or not can not be determined only according to whether there is water flowing out from the bottom of the basin. Because sometimes the basin soil hardens and shrinks into a ball after drying, and after watering, water flows quickly from the basin wall to the basin bottom and out from the bottom hole. The central part of the basin soil does not even touch a little water. If you stop watering at this time, it will wilt the leaves of Magnolia and form an arrow when it is running.
