How to mix soil with crab claw orchid
As an epiphyte of the cactus family, Crabclaw orchid is popular for its unique hanging posture and gorgeous winter flowers. If you want to grow crabclaw orchid with strong roots and vigorous flowering, soil matching is particularly important. This article will teach you hands-on how to create the most suitable growth substrate for Crabclaw Orchid from soil pH control to specific ratio plans. The core principle of soil allocation requires soil pH requirements. The original environment of Crabdodendron determines its characteristics of liking slightly acidic substrates. The ideal pH value is between 5.5 and 6.5. An acidic environment can promote the absorption of trace elements such as iron and manganese and avoid the appearance of yellow leaves. Special attention should be paid to alkaline water and soil areas in the north, and 0.2% ferrous sulfate solution can be irrigated every quarter. The matrix structure standard high-quality soil must meet the "three degrees": air permeability, water retention, and nutrition. It is recommended to adopt a gold combination of "organic substrate + inorganic particles", with the proportion of particles controlled at 30%-50%, which can not only ensure drainage but also avoid nutrient loss. Four classic soil matching schemes: professional-grade formula peat soil: perlite: vermiculite: pine needle soil =4:1:1:1. This formula takes into account ventilation and fertility retention. The pine needle soil continues to release acidic substances, which is especially suitable for rainy seasons. area. It is recommended to supplement 5% decomposed pine phosphorus every six months to maintain acidity. Option 2: Economic ratio of leaf soil: coal slag: volcanic rock =5:3:2, reducing the cost by more than 50%. Fully fermented leaf soil provides organic matter, coal slag needs to be sieved to remove powder, and volcanic rocks are recommended to use 3-5mm particles. Scheme 3: Universal substrate garden soil: humus soil: river sand =1:1:1, suitable for use in dry areas. River sand needs to be cleaned and disinfected, and it is recommended to add 10% coconut bran to improve water retention. Applying alum fertilizer water every month can effectively prevent hardening. Scheme 4: Improved formula peat: coconut bran: perlite: red jade soil =4:2:2:2, adding 5% bone meal as base fertilizer. This formula is particularly suitable for grafting crab claw orchid, and the porous structure of red jade soil can promote the development of rootstock root systems. Daily maintenance key pH maintenance In addition to regular acid supplementation, peel enzyme can be used to replace clear water for watering (once a month). Citrus peels are rich in citric acid, which can gently adjust the soil pH value. Water management techniques Keep the moisture of the substrate at 40%-60% in spring and autumn, control the water to 20% during summer dormant period, and increase it to 70% during winter budding period. It is recommended to use the bamboo stick detection method: insert it into 2/3 of the basin soil and pull out the absence of clay as a water shortage signal.
Through scientific soil allocation combined with fine maintenance, Crabclaw orchid can not only maintain its oily and plump leaves, but also achieve the grand scene of blooming every year. Remember to observe the condition of the plant regularly. When new leaves turn yellow and the roots are exposed, it is the best time to change pots and soil.
