The nutrient soil for growing flowers needs to meet the following conditions:

• Loose and breathable, conducive to the growth of plant roots;
• Retain water and fertilizer, and provide sufficient water and nutrients for plants;
• It is slightly acidic or neutral, suitable for the growth of most plants.

Different proportions of nutrient soil can be prepared according to different plant species. The following are some common preparation methods:

Universal nutrient soil

• Leaf mold: garden soil: river sand = 4:4:2

Acid-loving plant nutrient soil

• Leaf mold: garden soil: pine needle soil = 4:2:4

Alkaline plant nutrient soil

• Garden soil: wood ash: rice husk ash = 4:1:1

Succulent plant nutrition soil

• Granular soil: leaf mold: vermiculite = 4:2:4

Orchid nutrient soil

• Leaf mold: bark: broken bricks = 4:2:4

When preparing nutrient soil, you can add appropriate amounts of organic fertilizers, such as cake fertilizer, bone meal, etc., as needed to improve soil fertility.

Steps to prepare nutrient soil

1. Mix all materials evenly according to the proportion.
2. Sieve the mixed soil to remove larger particles.
3. To disinfect the soil, you can spray it with carbendazim or potassium permanganate solution.
4. Dry the disinfected soil in the sun and it is ready for use.

Precautions for using nutrient soil

• Newly prepared nutrient soil should not be used immediately. It should be left for a period of time before use so that the microorganisms in the soil can recover.
• When using nutrient soil, you should pay attention to the growth of plants. If you find that the soil is compacted or lacks fertility, you should make adjustments in time.

Source of nutrient soil

• You can prepare it yourself, or you can buy ready-made nutrient soil.
• If you prepare it yourself, you should choose materials of reliable quality.
• **When purchasing finished nutrient soil, you should pay attention to the product's quality instructions.
