What soil is best for growing white orchids?

1. What kind of soil to use

Its roots are fleshy, so it needs soil with good permeability. It is a southern flower and prefers slightly acidic soil and water, so it is best to mix it with coarse sand, garden soil and rotten leaves, and pay attention to the maintenance of water, fertilizer, light and temperature, and it will definitely grow well. If you are in the north, the soil is more alkaline. When preparing the soil, you can add some sulfuric acid powder to help increase its acidity.

2. Flower soil maintenance

If you are in the north, because the water is more alkaline, if you use it frequently, the soil will become alkaline, so it is best to use rainwater or add some ferrous sulfate to the water. However, because rainwater and snow are not easy to store, you can use tap water on a normal basis. Generally, you should use ferrous sulfate water once every ten days or so. This can help it avoid chlorosis.

3. When to change the soil

Changing its soil is the same as pruning it, both should be done once every two years. Each time you change its soil, you should use a larger pot than before. This can be done when the shed is out in the spring. After disinfecting the new flowerpot, put some broken tiles at the bottom of the pot as a drainage layer, then put about three centimeters of soil on it, put some horseshoe slices as base fertilizer, and then cover it with another layer of soil. Take the tree out of the original pot, remove the dead and old roots, plant it in, press the soil tightly, and then water it thoroughly.

Its sprouting ability is relatively low, so its branches are generally not pruned, but it is very necessary to remove the dead branches or branches infested by diseases and insects. It is also important to remove some leaves after the buds form, which will make the flowers grow larger and last longer.
