How to ferment sawdust to make flower soil How to use sawdust to grow green radish

Sawdust, like wood ash and coal, can be mixed into flower soil after fermentation, which is also good for the growth of flowers and plants. Sawdust cannot be sprinkled directly into flower pots, as it will burn the roots. So how do you ferment sawdust to make flower soil?

How to ferment sawdust to make flower soil

1. Take the ashes after burning

The simplest and crudest method is to burn the sawn wood and then sprinkle the ashes into the soil. The ashes from burning wood have a higher potassium content than wood ash. At the same time, like wood ash, the ashes from burning wood can be mixed with soil to play a sterilizing role.

2. Add water and ferment at high temperature

Put fresh sawn wood into a plastic bag or a container with a lid, pour in a proper amount of water (rice washing water or salt-free swill can also be used, and the effect is better. If there is cake fertilizer or chicken manure, sheep manure and other organic fertilizers on hand, you can also add a proper amount and mix them together for fermentation), make all the sawdust wet, cover the lid or seal the bag, and put it in a hot and sunny place. After fermentation and decay for about one to two months, the original wood color will turn into dark brown, which means it has completely decayed and fermentation is successful.

3. Compost

Composting is the most common method. Any wet garbage that does not contain salt or harmful substances can be piled together to rot and ferment into good-looking flower soil. Fruit peels and rotten vegetable leaves left in the kitchen, rotten branches and dead leaves, feces of furry children, fish intestines and scales left after killing fish, etc. can all be put into the compost bucket. After adding EM bacteria, they can quickly produce good-looking organic fertilizer.

Or in the countryside, you can just dig a big hole in a vacant lot, bury all the organic matter in the pit, bury a layer of kitchen waste and cover it with a thin layer of soil, then let it be exposed to the wind, sun and rain, and after half a year or a year it will turn into black and fertile soil.

How to grow green radish with sawdust

① Use dry sawdust to keep flowers and plants warm in winter

In winter, we cannot use sawdust as fertilizer for flowers, but we can use dry sawdust to keep the roots of flowers warm. Spread a layer of dry sawdust on the ground (or on the flower pot) to keep the roots warm. In the cold winter in the north, this method can keep plants warm and help them survive the winter. It's just that it's a bit more troublesome to grow and bloom plants in winter, because when watering the pot soil, you have to remove the sawdust, add a little water, and then spread the sawdust on top.

②. Sawdust that rots after fermentation is rich in nutrients

After fermenting sawdust, you can use it as nutrient soil for flowers and plants, so that they can grow vigorously and bloom abundantly. Because the fermented and rotted sawdust is nutritious, when you plant plants, you can add garden soil and coal slag to mix it, so that the soil is rich in nitrogen, phosphorus and potassium, and keep the soil moderately moist and loose. The fermented and rotted sawdust makes the soil fertile and breathable without accumulating water, which is conducive to the growth of plants with strong roots, thick branches and luxuriant leaves, and colorful when the flowers bloom!

③. Wet sawdust as a substrate for cuttings

When sawdust is dry, it can not only keep the roots of plants warm in winter, but also be used to wet the sawdust with water (it is better to hold it with your hand without dripping water) because it is porous and has good water absorption. Use wet sawdust as a rooting medium for cutting propagation, such as rose branches and gardenias. Put the wet sawdust in a small plastic bag, put the cuttings in 3 cm, tie the mouth tightly to facilitate moisture retention, and put it in a cool and ventilated place to promote rapid rooting. Or you can use sawdust and soil mixed as a medium for cutting propagation.

The benefits of sawdust as flower soil and fertilizer

1. Environmentally friendly and economical

On the one hand, it makes full use of resources, and on the other hand, it saves a lot of costs for my flower-growing hobby.

2. Loose texture, many gaps, good water retention

The texture of sawdust is very loose, and it is not easy to condense into blocks like sand, but it is much lighter than sand. There are many gaps between the tiny particles of sawdust, which can allow sufficient convection between the air in the air and the air in the soil, promoting the healthy growth of the root system. Another important key point is that sawdust has excellent water retention. It is precisely because sawdust is both permeable and water-retaining that treated sawdust is often used for branch cuttings or high-pressure cuttings to propagate plants.

3. The elements contained are very comprehensive

Generally, sawdust contains a comprehensive range of nutrients, which will not cause plants to have too much nitrogen and lack phosphorus and potassium. However, as mentioned above, the fertility contained in sawdust is relatively thin, and the release rate is very slow. It is not suitable for some plants and flowers that require a large amount of fertilizer. It is still necessary to apply organic fertilizer or compound fertilizer to achieve the purpose of supplementing nutrition.

4. Mix with garden soil to improve soil quality

On the one hand, the texture of sawdust itself is very loose and it is not easy to compact into lumps. On the other hand, sawdust is constantly being decomposed by microorganisms and is changing, so it can promote the benign improvement of garden soil or loess soil that is prone to compaction.
