Winter maintenance of geranium

The geranium likes to be warm in winter and cool in summer. It can blossom normally when the indoor temperature is kept at 15c in winter and the temperature is above 8 ℃ at night. But the optimum temperature is 15-20 ℃. Geraniums like dryness, hate dampness, watering in winter should not be too much, should be dry and wet. When the soil is wet, the stem is tender, which is not conducive to the sprouting and opening of flower branches; long-term excessive humidity will cause plants to grow too long, flower branches will move up, and the leaves will gradually yellow and fall off. Geraniums need plenty of sunlight for a long time, so they must be placed in the sun in winter. Lack of light, long stems and leaves, soft pedicels and poor inflorescence; buds in low light often bloom poorly and wither ahead of time. Geraniums do not like big fertilizer, too much fertilizer will make geraniums grow too prosperous and not conducive to flowering.

In order to bloom luxuriantly, watering dilute book fertilizer water (rotten bean cake water) once every 2 weeks can promote normal flowering by watering 800 times potassium dihydrogen phosphate solution every 7-10 days. Cutting off the abortive flower stem in time after flowering can increase the light between plants, induce the germination of new leaves and draw out new flower stems.
