② should be watered 1-2 times every morning and evening to keep the soil moist.

③ will be able to put the irises in a sunny place after a week, because the irises have adapted to the environment.

Planting method of Iris

Iris can be divided into perennial root Iris and bulbous Iris according to its underground stem, among which Iris can be propagated by seeds as well as ramet propagation.

Perennial irises can be divided every one or two years, the method is to dig out the original iris, and then divide into 3-4 plants (which can be divided according to the number of irises), and then plant them, the ramets of iris are usually after the iris, of course, we should avoid the plum rain season, as long as we ensure that the iris can sprout before winter. Then the ramet flowers can sprout in the next year. When dividing the rhizome, the rhizome can generally be set aside 3-4, ramet can not be too thin, split out of the iris to cut off the upper leaves in general, about can leave 20cm for planting, it is more suitable for shallow planting.

Seed planting: planting as soon as the seed is ripe.

Iris bulb can be propagated by planting bulbs, which will deplete nutrients in the process of flowering, and then produce new balls and bulbs at the same time. General bulbs can develop into flowering bulbs in 1-2 years.

[FAQ] how to grow irises? Planting methods and matters needing attention of Iris

[expert answers]

Iris is usually pressed into the soil with the thumb. The soil needs to be loosened and slightly moist before planting. After planting, cover the seedbed with soil until the ball tip is just covered. The soil temperature of bulb should not be higher than 20 ℃, light should be needed in the process of growth, and water should not be too much. The specific maintenance points are as follows:

1. Temperature

The temperature after planting is the most important factor, the temperature is above 5 degrees, the highest temperature is about 20 degrees, and the most suitable temperature is about 17 degrees.

2. Humidity

The ideal relative temperature is about 75%. Pay attention to avoid large changes in humidity or gradual changes in humidity. In warm sunny, shady or humid weather, the relative humidity tends to be higher. Corresponding measures must be taken to reduce humidity through simultaneous heating and ventilation.

3. Shading

Shading can control the temperature, humidity and light in the greenhouse. In the month of strong light, the temperature of ventilated greenhouse and open field is too high (more than 25 ℃). In this case, shading and ventilation can inhibit the decline of cut flower quality.

4. Fertilization

The chemical fertilizers commonly used in greenhouse Phalaenopsis include potassium dihydrogen nitrate, compound fertilizer and some special flower fertilizers for orchids. The application method is to add water to 2000 times diluent and then spray manually or add to the automatic sprinkler irrigation system. According to the different growth period of Phalaenopsis, the composition of chemical fertilizer should be different. The ratio of nitrogen, phosphorus and potassium is 20-20-20-20 in the vegetative growth stage of small seedlings, 7:11:27 in large seedlings and flowering plants. The interval of fertilization should be sprayed once every 7 to 10 days.

5. Pest control

There are common hazards of brown spot and soft rot, which can be sprayed with 1000 times of carbendazim wettable powder. Insect pests are harmful to shell insects and whiteflies, which are sprayed with 2.5% cypermethrin EC 3000 times.

6. Post-anthesis treatment

After the flower has withered, the flower stem can be cut off from the base, and when the matrix ages, it should be replaced in time.
