Culture methods of Iris

Iris, also known as Alice, is a perennial herb of the Iris family, with large and beautiful flowers, green leaves and high ornamental value. many kinds of irises can be used to decorate flower beds in gardens, planted in water-wet borders, by the lake, or arranged into iris special gardens, and can also be used as cut flowers and ground cover plants. Let's take a look at the cultivation methods of irises.

Growth habits of Iris

There are many varieties of Iris, and their growth habits are slightly different, which can be roughly divided into two categories. The first kind of iris has strong rhizome, strong environmental adaptability, drought tolerance and grows well under the conditions of sufficient light, good drainage and proper amount of fertilizer and water, such as German iris, iris, Gyabgon iris and so on. The second kind of iris likes to be wet and grows well in moist soil or shallow water, such as calamus, calamus, butterfly and so on.

Classification of Iris cultivars

1. Aquatic: Dictyophora, calamus and swallow flowers are all water-wet iris flowers, which are excellent materials for waterside greening, and are often used for special gardens, flower beds, waterside configuration and cut flower cultivation.

2. Xerophytes: Iris chinensis and Acorus tatarinowii have strong adaptability to soil and water, and can resist drought. This kind of flowers are mostly used as ground cover and edge plants.

3. Middle students: Iris, butterfly, German iris and silver iris are born in the soil with good drainage and moderate humidity. this kind of flowers are widely used and can be planted as special gardens, flower beds, flower borders, ground covers, etc.

Culture methods of Iris

1. Reproduction: Iris usually propagates by means of ramet and cuttage, or by seeds. Ramet propagation is more than in early winter or early spring dormancy period, cutting propagation is mostly propagated in spring, sowing is sown immediately after seed harvest.

2. Soil: Iris will grow poorly in acidic soil, so culture iris should choose clayey loam rich in humus or alkaline soil mixed with calcareous. Before planting, the soil should be fully ploughed and applied with rotten compost and a small amount of bone powder and plant ash as base fertilizer. In addition, irises should not be planted too deep, and the roots should be pressed.

3. Temperature: the optimum growth temperature of Iris is 15-17 ℃, and it likes the moist environment with plenty of sunshine. However, if the light is too strong, shading should be carried out properly, and if the humidity is too high, the humidity can be reduced by heating and ventilation.

4. Watering: iris should be watered once after planting, and then it can be watered according to the dry and wet condition of the soil. Do not make the soil stagnant or too wet for a long time, so as to avoid rotting roots or diseases. In order to keep the plant beautiful, the leaves of the plant can be cleaned.

5. Fertilization: rarefied cake fertilizer or compound flower fertilizer should be applied once or twice before iris sprouting and growing to flowering in spring, and liquid fertilizer should be applied again after flower withering.

6. Disease prevention: the disease that is easy to occur in the process of iris culture is soft rot. If soft rot is found in the plant, the plant should be dug up in time, the rotten part should be removed, the planting site should be changed or the pot should be changed for transplanting. The main pest of Iris is bean beetle, which is mainly treated by artificially killing adults and poisoning larvae. Between April and May, irises can be infused with 250 times 25% wettable imidophos to prevent the harm of underground pests, and clean dead leaves and destroy branches in winter, which can also reduce the occurrence of iris diseases and insect pests.
