Care and Management Methods and Tips for Potted Geraniums

Geraniums (see details) originate from southern Africa and are now widely cultivated around the world. In the West, geraniums are excellent flowers for decorating windowsills, and many flower enthusiasts now grow potted geraniums on balconies, which looks very beautiful. So how should potted geraniums be cared for?

Geranium (see details)

1. Light:Geraniums actually quite like light, especially in autumn, when you should find a way to give them full sunlight. Because of the balcony, my flower rack basically has to be moved once every season to follow the light. If conditions permit, winter should also be given the maximum possible light, while in summer they should be placed in a shaded spot to avoid being scorched to death.

2. Temperature:The most suitable temperature for geraniums is 10--20 degrees Celsius, which means spring and autumn are the most suitable seasons, while winter is too cold and summer is too hot. So in summer, you must prevent exposure to the scorching sun and place them in a cool spot. In winter, the indoor temperature should not drop below 0 degrees, otherwise they will get frostbitten. If there is no heating equipment, turning on a 200-degree large light bulb in a small room also has a certain anti-freezing effect.

3. Planting pot:Although geraniums are not large plants, a pot that is too small still will not do, especially for trailing geraniums. It is best to choose a taller pot, and then keep the soil surface a little higher from the pot rim. This can, as much as possible, avoid the plant becoming too heavy and breaking after it grows large, acting like a small support. For upright types, choose a pot about 20 cm, while for Angel Eyes, if you want to grow them well, you need a pot of 30 cm or more.

4. Fertilizing:Applying too much fertilizer at one time will cause dehydration in geraniums. If too much fertilizer is applied, for example too much nitrogen fertilizer, it will cause the plant to grow wildly and not bloom. After over-fertilizing, watering frequently can relieve the symptoms.

5. Potting soil:Geraniums are suited to living in sandy soil. Mixing some sandy soil into the soil bought at the flower market is more beneficial to the growth of geraniums.

6. Watering:Geraniums should not be watered too much. If you find that the roots of a geranium have rotted, it may be because of excessive watering while the weather is also relatively hot and stuffy. Control the watering frequency to once every two or three days, and each time water heavily enough to ensure thorough watering.

7. Weather effects:Strong winds will break geraniums, while heavy rain will cause the root system of geraniums to be soaked by rainwater, resulting in a lack of oxygen for root respiration and thus rot.

Care and Management of Potted Geraniums

When summer arrives, the geranium plant stops growing, the leaves age, and it enters a semi-dormant state. At this time it can be moved to a cool indoor place, liquid fertilizer should be stopped, watering should be done on time, and on rainy days the pot should be laid on its side to prevent water accumulation and root rot.

By September, when the heat has passed and the weather is cool, repotting and soil replacement can be carried out. First cut the branches short, leaving only about 10 cm at the base of each branch, so that new shoots are sent out and new branches replace the old ones. Geraniums should be watered moderately, and the pot soil should not be too wet; it is best if half a day after watering the pot soil is semi-dry.

① Change the environment and adjust environmental care according to agricultural season and temperature. Generally, in spring and autumn, place them outdoors for care; in summer, when high temperatures bring them into a semi-dormant period, fertilization should be stopped, and it is best to place them in a ventilated, semi-shaded spot; if ventilation and shading are used to lower the temperature, their dormancy can be broken ahead of time, allowing earlier growth, development and blooming; outdoors, pay attention to preventing scorching sun exposure, high temperature and stuffy humidity, and water accumulation in the pot from heavy rain; in winter, it is best to place them indoors or in a greenhouse for care. In modern family life, an air conditioner can be used to adjust the suitable temperature. As long as light conditions can be met, year-round blooming can be achieved.

② Fertilizer and water management. Entering autumn, the temperature drops, the plant begins to grow and enters a vigorous growth period. At this time, fertilizer and water management should be strengthened, applying a dilute nitrogen, phosphorus and potassium compound liquid fertilizer once about every 10 days, and in early spring, autumn and winter applying additional diluted phosphorus and potassium liquid fertilizer. The pot soil should be kept moist, and strong fertilizer and high humidity must be avoided.

③ Proper pruning. For leggy branches and branches that have bloomed, carry out moderate pruning back to shape the plant and encourage new branches, but heavy pruning must be avoided; remove old yellow leaves to keep the plant clean and make the flowers more numerous and attractive.

④ Disease control. The main disease is leaf spot, which in severe cases can cause stem and branch rot and complete leaf drop. During management, diseased leaves should be removed promptly to prevent spread. The humidity and temperature of the cultivation environment must not be too high; good ventilation and air quality, along with scientific fertilizer and water management, can improve the plant's own disease resistance; according to actual conditions, spraying 200-fold equal-amount Bordeaux mixture has a good preventive effect.
