How to make acidic soil

In home gardening, soil pH is a key factor affecting plant growth. There is more alkaline soil in the north of my country and more acidic soil in the south, but a suitable growth environment for different plants can be created through artificial deployment. Mastering the skills of making and using acidic soil can make classic flowers such as gardenia and rhododendrons bloom more brightly. The four core methods for preparing acidic soil are natural humus improvement method collects natural acidic materials such as pine needles and oak leaves, and mixes them with garden soil in a ratio of 1:3 for compost. The piles are turned every week to maintain ventilation. After about 2 months of decomposition, the pH value can reach 5.5-6.0. This method is especially suitable for growing camellia and other varieties that require high organic matter. Preparation of peel fermentation liquor: Cut pineapple peel and citrus peel, bottle it, add water in a ratio of 1:10 to seal it. Place it at 25℃ for fermentation for 15 days, and open the lid to vent every week. When used, it is diluted 50 times and watered, which can not only regulate the acid but also supplement potassium. It is especially suitable for bulbous flowers such as Dayantong. Edible vinegar adjustment skills Use a ratio of salt-free rice vinegar to clear water at a ratio of 1:200, and evenly wet the soil surface through a spray can. It is recommended to apply it in 3 times, each time at an interval of 5 days, and be combined with pH test paper monitoring to avoid excessive acidification and damage to shallow-rooted plants such as Milan. The ferrous sulfate application specifications dilute the drug to a concentration of 0.2% and apply it no more than 3 times a month. Alternate use with humic acid fertilizer has a better effect and can make hydrangea flowers more colorful. Pay attention to preparing and using it immediately to avoid oxidation failure. Illustrated guide to five classic acidophilic plants 1. Gardenia: Blooms most vigorously when PH 5.0 -6.5, and when iron-deficient yellow leaves need to be supplemented with alum fertilizer water. Rhododendron: Recommended soil matching peat + pine scale + perlite (6:3:1) 3. Camellia: A small amount of sulfur powder can be buried in spring and autumn to maintain acidity 4. Hydrangea: The color can be changed by adjusting the acid. Blue flowers will bloom below pH 5.5. Milan: Combined with the application of ferrous sulfate can enhance the concentration of floral flowers. Reasonable use of these acid regulation technologies and regular testing (it is recommended to use electronic PH meters) can not only improve the soil structure, but also activate trace elements. Remember the principle of "small amounts and multiple times" application so that each acid-loving plant can thrive in the most suitable acid and alkali environment.
