Monthly management of geranium

Families and genera: Bovidae, Pelargonium.

Scientific name: Pelargoniumhortorum.

Aliases: Hydrangea, foreign butterfly, paraffin red.

Habits: pelargonium, native to southern Africa, is a perennial herb with a sexual preference for a warm and humid environment. It is not resistant to cold and summer heat. The suitable temperature for growth is 13-19 ℃ from March to September and 10-12 ℃ in winter. Like plenty of sunshine, afraid of sun exposure in summer, suitable for semi-overcast environment. It is slightly resistant to dryness for fear of wet water. Require fertile, loose, well-drained soil.

January: put in a sunny place to prevent victimization. Watering when the weather is fine, it should be carried out at noon, do not use snow water, cold water.

February: apply thin liquid fertilizer every 2 weeks, appropriately increase the amount of water, and pay attention to ventilation in good days.

March: cuttage propagation can be combined with pruning. Cuttings should be cut from mother plants that bloom frequently, pure varieties and good growth. Each ear is 4-6 cm long and has 2-3 nodes. The last leaf is cut off and placed in a cool place for one day. After the cut is dry, it will be cut. Select sandy land with high dryness and smooth drainage, rake deeply and make a seedbed, then mix 60% yellow mud with 40% bran ash and spread it on the seedling bed for cutting.

April: continue cutting propagation. Sowing and propagation, because the seed is not large, the soil cover should not be too deep, the heat preservation after sowing is 20-25 ℃, and it can germinate about 2 weeks after sowing. After the cuttings took root, the cuttings should be put into the pot in time, and the culture soil should be mixed with humus soil, rice bran ash and garden soil, and some compound fertilizer such as bone powder, phosphorus and potassium should be added. The flowering period is from April to June, and thin liquid fertilizer can be applied once a week. It can be moved to outdoor culture in the next ten days. When the seedling is 12-15 cm high, it is coring, which promotes the formation of lateral branches.

May: cut off the residual flowers in time after shedding the flowers, 3-4 cm away from the first leaf at the lower end of the pedicel, in order to reduce nutrient consumption and promote the growth of new flowers. Do a good job in fertilization, watering and pest control. When the seeds mature 40-50 days after flowering, they should be harvested in time and dried for storage.

June: with the end of the flowering period, short pruning should be carried out to make the plant short, strong, perfect and beautiful, without watering or fertilization for a week after cutting, so as to make the cut dry and shrink and avoid water dampness and rot. In the last ten days, when the plant enters a semi-dormant state, it should be cultured in the shade and cool, controlled watering and stopped fertilizing.

July: every day is watered mainly in the early morning, supplemented in the evening, and watered when dry. Drain water in time after rain and avoid stagnant water in the basin.

August: feasible cutting propagation in autumn. The geranium grows rapidly and needs to be turned over, replaced with new soil and re-cut every year, leaving the base about 10 cm. Also appropriate to trim some longer fibrous roots, the upper excess sprouts, but also appropriate peeling.

September: continue cutting. Grow rapidly, apply thin liquid fertilizer about 10 days, do not splash on the leaves.

October: begin to blossom until June of the following year. Pay attention to keep it away from the wind and the sun to prevent the attack of cold air. Move into the greenhouse in the last ten days and pay attention to ventilation.

November: ensure sufficient sunshine, control watering, fertilize in time, strengthen ventilation, and prevent the occurrence of diseases and insect pests.

December: room temperature should not be lower than 5 ℃, no drying, no watering, timely removal of residual flowers and dead leaves.
