There is a wide range of gardening soil, which is suitable for all kinds of plants. Here, based on the premise of flower gardening, I’d like to introduce several kinds of mixed soil. In general, a type of soil in good condition should has following characters:
1. Good conditions in aeration and drainage.
2. Fertile soil (contains appropriate fertilizer).
3. Granular (gathered and solidified by fine particles, contains moisture, nutrients and air).
4. Free of impurities.
5. Clean earthiness (without bacteria).
6. Slightly acidic (almost all plants are like slightly acidic or neutral soil).
With the above conditions, here are examples of mixing ratio of gardening soil on the market for different plants:
- Herbaceous plants: Ruby soil: Leaf mold: Vermiculite = 5:3:2
- Flowering Tree/Court tree: Ruby soil: Leaf mold = 7:3
- Foliage Plants: Ruby soil: Peat soil: Vermiculite = 5:3:2
- Succulent Plants: Mixing soil of Kiryu sand and equal amount of Daytime soil: Peat soil/ Leaf mold = 9:1
- Weeds: Araki Land (plant with ruby soil, then covered with gravel thus to prevent soil floating)
- Mixed soil for Hanging bowl: Ruby soil: Leaf mold: Vermiculite = 4:3:3
ps: You should take the water absorbency into account with soil for hanging bowl, then based on which to decide pay the mixed ratio.
