Trailing, stem branches brown, tender stems green or with redness. Leaves ovate or Obovate, smooth, thickly leathery, margin sparsely dentate. Umbels with crimson, pink and white flowers.
Methods of reproduction:
Sowing and cutting are OK, mainly by cutting. Except that the cuttings are easy to rot in high temperature season from July to August, they can be used in other seasons. Cut the sturdy branches, grow 10cm or so, dry them for a few hours (leaving only one or half of the top leaves), insert them into the clean river sand, deep 3cm or so, place in the shade, keep the basin soil moist, and take root in about 1 month. Sowing seeds are generally sown with picking, and it is very easy for seedlings to emerge.
Cultivation management:
The trailing geranium is not strict on the soil, but it is suitable for the sandy loam with good drainage.
Vine geranium sexual like the sun, but avoid sun exposure, summer should be placed in the shade, when the plant is in a semi-dormant state, it is appropriate to stop fertilization. Fertilization is mainly phosphorus and potassium fertilizer, and an appropriate amount of organic liquid fertilizer, so as not to cause excessive growth and affect flowering. In order to make the plant full and grow neatly, the heart should be plucked many times during the growing period to promote new branches, and at the same time, yellow leaves or oversized leaves should be removed in time, as well as too dense and delicate branches, so as to make the inside of the plant transparent. Frosts Descent moved back and forth into the indoor sunny place, the ventilation is good, the temperature is not lower than 5 ℃, so as to avoid freezing injury, watering should be strictly controlled at this time.
Vine geranium grows fast, so the pot should be changed once a year and the old root should be removed in time. The basin change should be carried out before and after leaving the room from March to April.
Purpose:
Trailing geraniums can be watched in pots, and flower beds can be arranged on May Day, National Day holiday and other festivals.
The whole plant can be used for medicine, and some varieties can extract spices.

Raise geraniums skillfully in autumn
After the hot summer, the natural sunflower, which is in a semi-dormant state, begins to recover gradually, growing leaves and blossoming again, adding color to the golden autumn. However, it is inevitable that the geranium, which has just passed through the hot summer, is undergrown because of its old roots and leaves. The newly extracted leaves are small and dark green, the petioles and inflorescence stalks are short, the bouquet is small, and the whole plant shape is clustered, which reduces the ornamental value. The treatment of geranium with gibberellin can effectively promote the blooming of leaves and flowers and improve the ornamental value. The method is that when the inflorescence stalk of the first batch of flowers changes from curved to erect after the growth of the geranium plant is restored.

At present, the commonly used varieties are 'Tornado' and 'summer rain'. Among them, 'tornado' has the advantages of strong branching ability, short internodes, good plant type, heat resistance, rain resistance and so on. The trailing character of 'Xiayu' is obvious.
