Most of the open field flowers require neutral soil(20 cell trays bulk), only a few flowers can penetrate strong acid (plh4.5 ~ 5.5) or alkaline (pH 7.5 ~ 8.0) soil filling, and can not be replaced by other elements. It is suitable for neutral and slightly acidic flowers (pH 6 ~ 7); chrysanthemum, asparagus, asparagus, poinsettia, Osmanthus fragrans, inverted golden bell, Clivia, Narcissus, dandelion(23cm plastic grow pots), sijilou grass, Begonia pedunculata, etc.

The vast majority of garden soil in vegetable garden(50 cell seed starter trays), orchard and seedling solid is wall soil or sandy loam soil which has been decomposed for many years, so it is suitable for planting flowers. Sand and clay can not be directly used to cultivate flowers and need to be improved before use(plant plastic trays). Clay accounts for 45% ~ 100%, and only 0 ~ 35% of the sand with the particle size of 0.02 ~ 2 mm accounts for 0 ~ 35%.(cheap large plastic plant pots suppliers panama)
At the same time(50 cell plastic propagation tray wholesale price), the vast majority of greenhouse flowers (potted flowers) require acidic or slightly acidic soil, because within this range, the nutrients that flowers and plants need to absorb from the soil are in an absorbable state(v9 nursery pots). Above or below this range, some nutrient elements will become unabsorbable, cyclamen, camellia, jasmine, grape, cactus, Limonium, which will lead to nutritional deficiency of some flowers.
(cheap large plastic plant pots suppliers panama)Among them, carbon, hydrogen and oxygen can be obtained from water and air(72 cell seed starter trays); trace elements for flowers are very small, and the content in general soil can meet the requirements: nitrogen, phosphorus, potassium, calcium, phosphorus, magnesium, sulfur, iron and other elements can be supplied by the soil(plastic nursery trade pots). Flowers can be divided into the following categories according to their requirements for soil acidity and alkalinity.
Suitable for weak acid flowers (p5-6): Begonia, vermilion, Milan, Michelia, big rock pot, five needle pine, brandy, palm willow, cycas, etc(18 cell seed starting trays). It is suitable for neutral and slightly alkaline flower discards (P7 ~ 8): Rose, carnation, geranium, Yingchun, Nandina, Cupressus, Nerium, boxwood, Hibiscus syriacus, Shicao, wisteria, limonine, etc(3.5 inch square plastic pots). If the improvement needs to be mixed with sand, more organic fertilizer should be applied.(cheap large plastic plant pots suppliers panama)
Clay is a kind of soil with dominant clay content but little sand content(40 cell seed starting trays). It has strong water and fertilizer conservation capacity, and contains more nutrients for plants, but it has poor permeability, wet sticky and dry hard, and large soil block, which is not easy to cultivate(plant trays without holes). The 16 elements are carbon, hydrogen, oxygen, nitrogen, sulfur, calcium, magnesium, iron, manganese, zinc, copper, manganese, molybdenum and chlorine.
(cheap large plastic plant pots suppliers panama)Each of the above 16 nutrient elements has its special physiological function in flower life activities(20 cell seed starting trays). Not only a large number of elements are necessary for the growth and development of flowers, but trace elements are also indispensable in the process of flower growth and development(sureroots deep cell plug trays). Due to the different origin of flowers and plants, potassium, there are some differences in the requirements of soil acidity and alkalinity.
