Potting soil for home gardening: soil pH
Soil pH is a term that measures the acid and alkalinity content in the soil. PH is a symbol that indicates the degree of acidity and alkalinity. Its corresponding values are shown in the following table: PH3-45678910-11 Strongly acidic acidic weakly acidic neutral weakly alkaline alkaline strongly alkaline soils with a pH less than 7 are acidic soils, and soils with a pH greater than 7 are alkaline soils. Table of soil acidity and alkalinity of various flowers and trees: (1) Acid-tolerant flowers and trees (PH4-5): azalea, hydrangea, gardenia, coleus, purple spiderwort, fern, orchid, etc. (2) Suitable for weakly acidic flowers and trees (PH5-6): cyclamen, begonia, red primrose, camellia, jasmine, Milan, five-needle pine, lily, gladiolus, palm, white orchid, gloxinia, etc. (3) Suitable for neutral to slightly acidic flowers and trees (PH6-7): chrysanthemum, asparagus fern, rose, daffodil, hyacinth, osmanthus, primrose, spring orchid, poinsettia, fuchsia, calla, Clivia, purple magnolia, begonia, etc. (4) Suitable for neutral to slightly alkaline flowers and trees (PH7-8): rose, carnation, geranium, cactus, forsythia, boxwood, nandina, sweet pea, elmleaf plum, juniper, etc. The simplest way
to measure the pH of potting soil is to buy some pH test paper, litmus paper and a standard colorimetric card from a chemical store. When measuring, take a small spoonful of potting soil, put it in the bottom of a clean bowl, and add a small amount of distilled water until the test soil is just covered, not too much. Then stir and clarify, which is the soil extract. Use a bamboo stick to dip some soil extract on a small piece of test paper. The color card number that is red and similar to it is the pH value of the potting soil being measured. How to measure the acidity and alkalinity of the soil When growing flowers at home, most people buy mountain mud in flower shops and markets. In fact, not all flowers and trees need mountain mud. Flowers like azaleas and camellia are more sensitive to soil reactions and need slightly acidic soil to grow and grow well. Others such as roses and pomegranates do not need acidic soil. Ordinary loose neutral soil is enough, otherwise, they will not grow well. The acidity and alkalinity of the soil are generally expressed by pH value. Slightly acidic generally refers to pH5.5-6.5. The acidity and alkalinity of potting soil can be measured with "standard test paper".
