Can flowers be planted in hardened soil? How to deal with hard soil in flower pots?

As people's quality of life improves, more and more people like to grow two or three pots of flowers at home. However, the soil becomes hard as time goes by. Can flowers be planted in hard soil? How to deal with the soil in the flower pot that is too hard? Let's take a look.

Can flowers be planted in hardened soil?

The simplest, direct and effective way to fix the soil in the flowerpot is to change the soil. However, if you do not want to change the soil, you need to improve the soil. The way to improve the soil is to add organic fertilizer. We can spread the decomposed cow dung or chicken dung on the surface of the pot soil, and then loosen the soil. After fully mixing the organic fertilizer and soil, water it thoroughly. This method can increase the organic mechanism in the soil, thereby changing the condition of soil compaction. Or add soil mixed with leaf mold, mudstone soil, perlite, sandy soil, etc.

How to deal with the hard soil in the flower pot

1. The most direct solution is to change the soil, replace it with loose, breathable soil with slightly coarser particles or other substrates.

2. Loosen the topsoil of the potting soil for a few centimeters, but be careful not to damage the roots of the flowers. Then add some organic fertilizer and mix it evenly with the topsoil. Organic fertilizer can effectively improve the pH value of the soil and the problem of compaction. If there is no organic fertilizer, you can add some leaf mold or dead leaves, which need to be crushed.

3. If you find the above two methods troublesome, loosen the soil after the watering is slightly dry. Then spread some dry moss on the surface of the pot.

How to disinfect the soil for growing flowers

Fire, roasting

Light some vegetable leaves, rotten paper scraps and some dead branches and leaves in a small space surrounded by earth blocks, in the open air. When the flames are the strongest and the earth blocks are the hottest, pour the soil in. Use high temperature to sterilize and kill insect eggs. This method is similar to burning straw piles in rural areas in the past. This method is suitable for rural areas. Be careful to prevent sparks from spreading everywhere.

Exposure to the sun, ultraviolet sterilization

In summer, spread the flower soil on the cement floor. When the cement floor is hot and the soil lacks moisture, with the help of ultraviolet light, some bacteria can be killed, and the eggs will also be dehydrated and die. Some hidden pests will also run away without a trace.

If conditions permit, you can spread the soil on iron sheets. The higher the temperature, the more effective it is. Collect the hottest flower soil in a plastic bag, compact the soil slightly, dry it, and keep it at high temperature for a long time. This can kill insect eggs more effectively.

Drug sterilization and disinfection

Soil exposure to the sun can be disinfected and sterilized. If it is supplemented with drugs, it can be a two-pronged approach. It can kill bacteria and insect eggs more effectively. After the flower soil is exposed to the sun, collect it in a foam box, and then dilute "potassium permanganate" or "carbendazim" with water to a certain multiple, wet the flower soil, and then seal it. This can achieve the best effect.
