How to prevent the rotting roots of geraniums

Geranium, also known as stone red, Ren La Hong, Hydrangea, Hydrangea, is a subshrub or perennial herb of the family Niuer Seedling. The whole body is covered with fine hairs and has a special smell.

Native to southern Africa, it is now widely cultivated all over the world. Like cold and cool climate, suitable temperature 10: 25 ℃, can withstand 0 ℃ low temperature, enter semi-dormancy state in summer high temperature period; like sufficient light, when lack of light, do not blossom. Flowering should avoid direct strong light, otherwise the flower is scorched, easy to wither; resistant to dryness, avoid moisture, too much water has the risk of death; like loose soil with good drainage. The full flowering period is from April to June, and the florescence is long. If higher temperature is given in winter and properly managed, it can blossom continuously from October in autumn to June of the following year.

Spring and autumn are the period of exuberant growth of geranium, so you can pour more water appropriately. When the summer temperature is high, the geranium is semi-dormant, so watering should be strictly controlled. To basin soil is not too can, at the same time, it is appropriate to water in the morning and evening, when the soil temperature is high at noon, do not water, otherwise it is very easy to cause root rot. Rainy days should be protected from the rain, in the "plum rain" season, must not let the basin soil for a long time too wet.

In order to prevent the rotting of geranium roots, sandy loam rich in humus and good drainage and air permeability should be selected in addition to watering. The clay structure produces poor drainage and air permeability and can not be used to plant geraniums.

When transplanting geraniums, the shovel should not be too close to the roots so as not to damage the roots. The roots should be kept intact as much as possible. if the roots are hurt, they are most likely to mildew and rot after watering.

In order to keep the roots of geraniums from rotting, it is necessary to control diseases and insect pests in time. Nematode is a common pest of geranium. When the temperature is 2530 ℃ and the humidity is about 40%, it is the most suitable time for nematode to invade the root of geranium. When the damage is serious, the root system will fall off one by one, or even rot completely.

How to prevent Pelargonium rotting Root Prevention measures: ① soil. The sandy loam with rich humus, good drainage and good permeability was selected and transplanted by ②. When transplanting, keep the shovel away from the root as far as possible to avoid root damage and root rot. ③ watering. Is the key to prevent root rot, usually can not be more watering, in the spring and autumn when the growth is exuberant, you can appropriate a little more water. Summer high temperature to strictly control watering, to basin soil is not very dry, especially at noon when the temperature is high, must not be watered. In the rainy season, the management should be strengthened and the basin soil should not be too wet for a long time. ④ pest control. Nematode is the main pest that causes root rot of geranium. When planting, it is best to use artificial media such as perlite and vermiculite, or disinfect the soil with 3% carbofuran particles (25 square centimeters and 8-10 grams). The diseased plant was removed and burned in time. How to prevent the rotting of geraniums

There are many reasons for geranium rotting roots, too much watering, resulting in stagnant water in the basin; muggy environment, poor root breathing; diseases and insect pests, gnawing roots; improper fertilization, root burning. Any inappropriate behavior in maintenance will cause root rot. The point is not to analyze the cause, but to find a way to avoid it.

Prevent the rotting of geraniums-choose the right soil

The quality of the soil determines the root growth of the geranium. choose the sandy loam rich in humus, good drainage and good permeability. The root growth is robust, the resistance is light, the timely maintenance is improper, and it will not rot easily.

Prevent the rotting roots of geraniums-be careful when transplanting

Geraniums turn over or change large pots every autumn, which is the cause of extensive damage to the roots. So in the operation, the shovel away from the root system, to avoid shoveling the root system, to know that each wound is fatal to the plant.

Prevent the rotting of geraniums-watering correctly

Correct watering is the key to prevent root rot, usually do not water more, spring and autumn growth season can be appropriate to pour a little more water, but the basin soil can not accumulate water.
