How to propagate firecracker flower

Preparation before cutting of firecracker flower

Cutting selection

Generally, it is suitable to choose 2-year-old vines for cuttings in May and June, or it is suitable to choose semi-lignified vines of the same year for cuttings in September and October. At this time, choose semi-lignified vines of the same year and cut them during the period from when they stop growing to before the differentiation of flower buds. It is suitable to choose the middle vines with shorter internodes, large and full buds and strong growth as cuttings.

Cuttings processing

Cut cuttings with 2-3 nodes, with the cut edge being beveled and smooth. 2-3 leaflets should be retained at the front end of the cutting to promote root growth. Before planting, treat it with ABT rooting powder and then disinfect it with potassium permanganate solution.

How to propagate firecracker flower

Use the trenching and covering method, insert the branches obliquely, halfway into the substrate, leaving one section above the ground, and water thoroughly after insertion.

Management of firecracker flower after planting

Light Temperature

The temperature in May is generally stable at 20-25℃, which is conducive to cutting propagation. When the soil temperature in the seedbed is about 3-5℃ higher than the air temperature, it is more conducive to rooting. A double layer of shade net should be used for shading, and one layer of the net can be removed about 2 weeks after planting. About a month after transplanting, most cuttings have formed callus tissue. The shade net should be removed in the morning or evening to expose the cuttings to appropriate light to promote rooting.

Moisture

Generally, keeping the cutting bed moist and maintaining the air humidity at 80%-90% is conducive to rooting. You can spray water mist 1-2 times a day to increase the air humidity. When the sprouted roots grow to about 2 cm, you can add an appropriate amount of water. At the same time, it is best to let the soil in the bed dry out after a period of time before watering it thoroughly.

Fertilization

When the roots of the cuttings grow to about 1 cm, you can spray potassium-containing liquid fertilizer. When most of the roots of the cuttings are up to 3 cm long, you can apply three-element liquid fertilizer every half a month or so to promote the growth of leaf buds.
