Pine Needle Soil
At some places, pine needles are quite common, and after decomposition, they become a great fertilizer for plants. A simple way to use them is to place a layer of dry pine needles directly at the bottom of the pot and then cover it with soil to make the soil loose, well-aerated, and well-drained.
You can also compost pine needles and mix them with soil for planting. After being composted, pine needles contain nitrogen, phosphorus, and potassium. These are all essential nutrients for the growth of plants.
If you want to compost pine needles, put them in a sealed bag, water them thoroughly, and then seal the bag and let it dry in the sun. The high temperature will cause the pine needles in the bag to slowly decompose. After about 3 months, you can take out the pine needles and use them.
You can mix the composted pine needles with soil and kitchen waste such as leftover or spoiled fruits and vegetables. Put them all in a closed container, add a suitable amount of water, mix well, and cover the container. It will compost faster if you place it in the sunlight.
This type of soil is rich in nutrients, loose, and well-aerated, making it suitable for various types of plants. You can use it to plant flowers.
You can also compost pine needles with sunlight, wind, and rain. Here’s how: after collecting pine needles, you can spread them under trees or in the garden to compost naturally. This method may require more effort, but it has a disadvantage that pine needles are prone to insect and bacterial attacks during composting. Therefore, you need to sterilize them before using them to plant flowers. If used directly, they may cause damage to the plant’s roots.
Cinnamon Trunk Soil
With good air permeability, soil containing cinnamon trunks can provide adequate fertility and contain many essential trace elements for the growth of plants. Cinnamon trunks contain copper, manganese, iron, potassium, phosphorus, nitrogen, and other nutrients. In addition, they also contain various plant growth regulators. Therefore, it is not an exaggeration to say that they are a treasure for planting flowers.
To use cinnamon trunk soil, you collect wild cinnamon soil, dry it, and crush it. Mix the crushed cinnamon trunk soil and garden soil in a 1:2 ratio to make new plant beds. The characteristics of cinnamon trunk soil are being loose and well-aerated, so if you use it to plant flowers, you may not need to fertilize it for 10 years.
Plant Residue Soil
Plant residue is the material that remains after burning straw, leaves, etc. It is a liquid potassium fertilizer that provides quick effects and usually contains 5-15% potassium. It also contains iron, phosphorus, magnesium, calcium, and other elements.
Plant residue can effectively increase the temperature of the soil while keeping it loose. It also promotes the sprouting of plants, root growth, prevents leaf fall, and provides sufficient nutrition for plants.
One thing to note is that plant residue tends to be alkaline, so it should not be used alone. It needs to be combined with other types of garden soil before use to neutralize the alkalinity of the soil. It is best to mix garden soil with a small amount of plant residue before planting flowers.
