Why can t geraniums be kept indoors

Because its pollen can easily cause allergies in people.

Geranium has a strong fragrance, and the indoor space is small, and the fragrance fills the whole room, which can affect people's breathing. Insufficient light: Geraniums love light, and the indoor light is poor, which cannot meet the needs of the plants.

Poor ventilation: The indoor ventilation conditions are poor, and the water in the pot cannot evaporate, and there will be root rot and disease.

In fact, as long as you understand the preferences of geraniums, geraniums are very easy to raise, you only need to water once or twice a day, use slightly acidic sandy loam soil containing humus, and control the temperature at 15 25, usually pay attention to the prevention of ** pests and diseases There is no big problem.

1. Sufficient moisture

Autumn is the peak season for geraniums, at this time we must ensure that there is sufficient water, water once or twice a day, so that it is wet when it is dry, but there can be no stagnant water. On rainy days, geraniums need to be drained and placed in a ventilated area.

2. Soil environment

Many people will question whether geraniums are easy to raise, in fact, as long as the soil geraniums are very good to raise, it does not have high requirements for soil, choose a slightly acidic sandy loam soil with fertile, loose and well-drained humus, you can mix 3:3:4 humus soil, pastoral soil with a small amount of base fertilizer, feel that the soil is too complicated, you can go to the market to buy special nutrient soil.

3. Temperature requirements

Geraniums like Wen Zhaosen warm afraid of high temperatures, more cold-tolerant, the most suitable temperature in winter is 10 15, spring, summer and autumn the most suitable temperature is 15 25 rotation culture. It can survive in temperatures as low as 5 for a short period of time, and will freeze to death below 5.

4. Prevent insect pests

The common insect pests of geraniums are Spodoptera exigua, whitefly, for Spodoptera exigua, you can use black light to catch adults during the adult period, and for whiteflies, you can use chrysanthemum emulsifiable concentrate or sweeper control.

Geraniums are poisonous, but they do not emit harmful odors, and can be placed indoors for maintenance to purify the air. When cultivating geraniums indoors, humus, garden soil, and perlite can be mixed to make a substrate for cultivation. In spring and autumn, the soil needs to be slightly moistened, and liquid fertilizer should be applied every 16 days to supplement the nutrients.

Geraniums are poisonous, but do not emit harmful temperatures, and are suitable for indoor rearing, but should not directly touch the sap or eat the leaves. Geraniums have a very beautiful shape and high ornamental value, which can be matched with the furniture environment. And geraniums can absorb harmful gases in the air, release oxygen, and improve the quality of the air.

When cultivating geraniums indoors, humus, garden soil and perlite can be mixed into a cultivation substrate, and a sufficient amount of well-decomposed organic fertilizer can be mixed into the soil to improve the permeability and fertility of the soil. In addition, it is necessary to repot in autumn every year to loosen the soil in time to avoid the soil being compacted and impermeable.

When watering geraniums daily, it is necessary to follow the principle of preferring dry to wet, and to water more in spring and autumn to meet the water required for plant growth, so that the soil is in a slightly moist state, and it is necessary to discharge the water in the soil in time in rainy weather. In addition, liquid fertilizer needs to be applied every 16 days, and nitrogen fertilizer is mainly applied during the budding period, and fertilizer needs to be applied every evening.

When the geranium seedlings grow to 10 cm, they need to be pruned in time to promote the germination of new branches, and after the plants enter the growth period, they need to be thinned in time to prune the over-dense branches and over-long branches inside, and after the geraniums bloom, they also need to prune off the residual flowers and dead leaves in time to reduce unnecessary nutrient consumption.

Geraniums cannot be kept at home because the lack of light and poor ventilation in the home will affect the growth of geraniums.

Geranium is a light-loving plant, suitable for growing in a sunny environment, the daily light time should not be less than 5 hours, and the indoor light transmittance is poor, can not provide enough light for the plant, so geranium is not suitable for indoor breeding, otherwise the plant will be due to lack of light, poor growth, the phenomenon of growth.

Geraniums like moisture but are not resistant to waterlogging, suitable for growing in a well-ventilated environment, and indoor ventilation is poor, placing them at home will lead to damp potting soil, so that geraniums appear rotten roots and disease, so the plants are not suitable for breeding indoors, and it is best to be placed in a well-ventilated environment for maintenance.

In the process of breeding geraniums, the sedan chair should be used as the base soil of loose and breathable, nutrient-rich humus, and then placed in a sunny environment, and the sun is prepared to maintain 5 hours of light every day, and the plants like water, water every 5 days in spring and autumn, water every 2 days in summer, and water twice in January in winter.

Conservation management of geraniums

1. Temperature control.

The most suitable temperature environment for geraniums is 10-20 degrees, in summer it must be protected from sun exposure, it is best to put it in a cool place, and the indoor temperature in winter can not be lower than 0 degrees, otherwise the plant will be frostbitten.

2. Fertilization method.

In the stem and leaf growth period of geraniums, it is necessary to apply thin nitrogen fertilizer once every half month, and change the fertilizer to phosphorus fertilizer during the flower bud formation stage, and the frequency should be maintained once every 2 weeks, in order to control the plant height of geraniums, chlormequat can be sprayed on the foliar surface every week.

3. Trimming and shaping.

When the geranium seedlings grow to 10 cm, they should be topped to promote the germination of new branches, and after the plant enters the growth period, it is necessary to cut the over-dense branches and over-long branches inside in time, and after each flowering of geraniums, the residual flowers and dead leaves should be cut off immediately.

Xiaotian is relatively robust, has good adaptability, has fewer pests and diseases, and does not pick the soil quality of growth; In addition, it likes warm in winter and cool in summer, and is afraid of moisture, the most suitable growing season is spring and autumn, so in summer and winter, special attention should be paid to indoor temperature, generally room temperature can be more than ten degrees, so as long as you do a good job of watering moderately, fertilizing the appropriate amount, suitable temperature, prevention and control of pests and diseases, etc., even if it is placed in indoor breeding, Xiaotian can also be full of flowers.

1.Watering in moderation. Xiaotian is afraid of too wet soil environment, so even on a dry winter day, do not overwater, otherwise the leaves will turn yellow and fall off, and even rot from the roots and die.

Therefore, it is enough to water the potting soil slightly moist on a small day of indoor breeding for three to four days.

2.Fertilize to the right amount. Although Xiaotian can grow in a variety of soil conditions, after all, it is still necessary to apply appropriate fertilization for indoor potted ornamentation.

Because there are many factors to consider when applying fertilizer, such as the quality of the soil, the size of the flowers and pots, it is best to ask the store carefully at the time of purchase to know the amount of fertilizer and the frequency of fertilizer.

3.The temperature is right. The growth temperature of Xiaotian mentioned above, to sum up, it is necessary to have a warm environment in winter and cool in summer, and indoor breeding can basically meet this condition, but there are also matters that need special attention:

First, when it is hot in summer, avoid placing it in a place that is easy to be exposed to the sun, such as a sunny window sill, and move it to a cool place; Second, in winter, it is necessary to ensure that the indoor temperature should not be lower than zero degrees, otherwise it is easy to be frostbitten, and it must be placed in a sunny place to accumulate light in a small day to grow and bloom smoothly.

4.Control pests and diseases. The most common pests and diseases are gray mold and true mold, as long as they are placed in a well-ventilated place indoors, and the dry branches and leaves can be effectively prevented in time.
