Irises have attracted the attention of countless gardening enthusiasts with their unique temperament and elegant attitude. The moment it blooms, it is like a blue-purple butterfly fluttering, which makes people intoxicated. However, behind the beauty is the careful care and cultivation, among which, the first is the choice of soil environment.
Irises have a well-developed root system and are both picky and unique in their soil requirements. The ideal soil for cultivation should have good aeration and drainage, which is the characteristic of sandy soils. Sandy soilDue to its large particles and large gaps, it can effectively avoid root rot caused by water retention, and at the same time ensure sufficient oxygen supply to promote the healthy development of the iris root system.
Well drainedIt is a key element in the healthy growth of irises. Excessively wet soil can hinder the normal respiration of roots and cause pests and diseases, such as root rot. Therefore, when configuring the soil, we recommend using the ratio of three parts garden soil, two parts sand and one part humus soil, which can not only ensure the nutrients, but also ensure the rapid discharge of water and prevent the occurrence of water accumulation.
Root developmentIt is the basis for the vitality of irises. In well-drained, sandy soils, irises' root systems are able to extend freely, take deep roots, and absorb more nutrients. At the same time, the permeability of sandy soil also helps iris roots to form a healthy mycorrhizal symbiosis, further improving its absorption efficiency of nutrients in the soil.
Although sandy soils are preferred, they are not naturally available in all places. In order to create the best growing environment for irises, we need to make appropriate improvements to the soil:
Soil ploughing and loosening: Plough the soil regularly to keep it loose and conducive to water penetration and air circulation.
Add organic matter: Add an appropriate amount of well-rotting compost or humus soil to increase the water retention and fertility of the soil, which helps iris to thrive.
pH adjustment: Irises prefer slightly acidic soils with a pH of 60-7.0 is ideal, and limestone powder or sulfur powder can be used to adjust the pH of the soil if necessary.
High-quality sandy soils are essential for the development of the iris root system. In the actual cultivation process, we need to pay attention to the texture, drainage, nutrients and pH of the soil, and take care of every inch of the soil, so that the root system of irises can stretch and take deep roots in it, and finally bloom that breathtaking beauty. Let's water this blue elf with love and wisdom, let them fly freely in the flower field, and interpret their own chapter of life. Iris
