Perlite Super Coarse Horticultural Grade Expanded Perlite

Horticulture Grade Perlite – Horticultural grade perlite is derived from a naturally occurring, volcanic rock. When furnaced at high temperatures, perlite “pops” and expands up to 10 times its original volume. The resulting, lightweight particles are made up of microscopic spheres with a porous, irregular surface that stores moisture and promotes plant growth.
Our perlite products have proven themselves as a consistent growing media for horticulture because they improve the characteristics of every organic material they are mixed with including peat moss, compost, bark, coir, or in native soil. Horticultural grade perlite is stable and will not degrade or compact over time. It maintains consistent aeration and drainage for plant roots and will not decompose or deplete nitrogen levels in the soil.
Adding perlite to soil and growing media lightens the soil and introduces pore spaces that allow air and water to penetrate the root system. Excess moisture is permitted to drain out and maintain balanced air and moisture conditions which contribute to healthy biological and microbial activity, and minimize the chances for rot.
Uses – Propagation of seedlings and cuttings – Soil conditioning – Hydroponics – Roof deck gardens and eco-roofs – Nursery stock – Hanging baskets – Turf enhancement – Newly planted trees and plants

Application of clay pebbles/ leca in gardening and landsacping

The application of clay pebbles/ leca in gardening and gardening is a new use developed in recent years. In this regard, China already has a large amount of use, and the amount of clay pebbles/ leca used in gardening and gardening has accounted for about 5% of the output of clay pebbles/ leca. With the acceleration of urban construction, horticultural clay pebbles/ leca will have greater development, and its output will continue to increase. It is estimated that by 2010, the application of China’s clay pebbles/ leca in horticulture and gardening will reach about 10% of the total output, and it will also become one of the main uses of clay pebbles/ leca.

(1) Application in tree ponds, flower ponds, flower beds, and ground covering decoration When we go to Beijing now, we will see a layer of dark red balls covering the tree ponds and flower beds on both sides of the street, which is very beautiful. This is clay pebbles/ leca overlay. It can make the street look more beautiful, and can prevent tree ponds and flower ponds from being dusted by strong winds. It is beneficial to the purification of the air, and other cities have begun to cover tree ponds, flower ponds, flower beds and grounds with clay pebbles/ leca, and its consumption will increase year by year.

(2) Application in soilless cultivation of flowers Soilless cultivation is an emerging flower cultivation technology in recent years. The substrate raw materials used in the past are perlite, glass wool, pebbles, etc. In recent years, clay pebbles/ leca has been used as the cultivation substrate. . This is because clay pebbles/ leca is light, water-absorbent, and can provide certain nutrients, which is superior to other substrates. You can plant flowers and grass by putting clay pebbles/ leca in the flower tray. It is clean and tidy, and can be cleaned repeatedly without soil pollution, so it is more popular among people.

Fermented pine bark

Using pine bark as raw material, it is refined through the processes of collection, crushing, degreasing, grading, drying, and impurity removal. The capacity is close to that of peat. Compared with peat, the cation exchange capacity and water holding capacity are lower, but the ratio of carbon to nitrogen is higher. It is a better medium material.

The natural characteristics of pine bark – higher organic content; in suitable chemical composition, stable ph and lower ec content, higher n, p, k, ca, mg; stable physical properties, decomposition Uniform and slow, to achieve the effect of long-term fertilization; good air permeability and the effect of controlling air and moisture. The pine bark has a wide range of application space in flower cultivation, crop planting and other fields

Fresh pine scale medium is a superior natural medium, which can be directly used as the upper basin medium of the container. In the process of use, it has good water retention, fertilizer retention, water permeability and air permeability. The pine bark medium is suitable for various orchids such as Phalaenopsis, Cymbidium, Dendrobium officinale and Dendrobium spring. Soak in water for a week for better results.

Why do flowers like to use vermiculite? Advantages and disadvantages you need to know.

For friends who like to grow flowers, vermiculite is an all-too-familiar substrate. It is cheap, light in weight, and has excellent air permeability and water retention. It can be used with peat, coconut peat, and perlite for soil preparation. Growing flowers can improve the soil and adjust the pH of the soil; it can also be used alone as a cutting substrate, which is sterile and breathable, and has a certain degree of water retention, which is conducive to the rapid rooting of cuttings and can significantly improve the survival of cutting propagation It was once called the “artifact of cuttings”.

About the basic characteristics of vermiculite:
(1) Vermiculite is a mineral silicate material that has been expanded at high temperature. Its color is yellowish brown. It is a small particle with a slight twist like instant noodles. Magnesium, iron and other mineral trace elements, but almost no organic matter after high temperature expansion, belongs to the sterile matrix.
(2) It has a wide range of uses. It is not only a common substrate for soil preparation and cutting seedlings, but also can be used for hydroponics (soilless cultivation) and as insulation and hatching materials for reptiles.
(3) Use it to cut rose, geranium, crab claw orchid, succulent leaves, etc., not only take root quickly but also have a well-developed root system.
(4) Vermiculite is a neutral mineral, does not contain saline and alkali, and has a certain adsorption capacity. It can not only increase the bulkiness of the soil, but also regulate the acid-base balance of the soil.
(5) At the same time, it is also a cheap substrate, with high bulkiness and very light weight. It can be used for matching with peat, perlite, etc., which can reduce the total cost of soil preparation.

The role of vermiculite in the process of growing flowers:
In addition to improving the soil structure, making the soil more loose and air-permeable, and preventing water logging and rotten roots, vermiculite can also adjust the acid-base balance of the soil and keep the soil at a suitable humidity. The residence time and release cycle of fertilizers in the soil also have a certain positive effect on the growth of potted plant roots and the stable development of seedlings.

Precautions for using vermiculite:
(1) Vermiculite is pulverizing, and with the prolongation of the use period, it will gradually become powdery, losing its outstanding advantages, and its permeability and water retention will be reduced. Therefore, it is more suitable for use with other substrates, and the pot and soil should be changed every 1-2 years.

(2) There are various specifications of vermiculite, including block, flake and granular. For gardening, granular vermiculite is generally the best. Considering its own pulverization, it is not easy to choose too small particles when selecting the particle matrix. The particles of 1-3 mm are in the form of powder, and the particles of 3-5 mm are the most practical.

(3) Small particles of pure vermiculite can be used alone as a cutting substrate, but it is not suitable to be used alone to cultivate potted plants, because vermiculite contains almost no other nutrients except for some mineral trace elements. Using it together can learn from each other’s strengths and complement each other’s weaknesses. The proportion of peat, perlite, and vermiculite in a ratio of 5:2:3 can basically meet the growth needs of most potted plants.

As a granular substrate with good air permeability and water retention, vermiculite has multiple functions of soil improvement, soil pH stabilization and mineral trace element supply. It does have outstanding advantages in cutting propagation and root growth and development, but it is easy to pulverize. It is too light, and it is easy to float when watered, which is a fly in the ointment. Fortunately, there are quite a lot of granular substrates in the horticultural field. Medical stone, red jade soil, deer marsh soil, etc. are also commonly used soil granular substrates. Choose, make full use of strengths and avoid weaknesses!
