Egg shell

1. After washing the egg shell, crush it and sprinkle it on the surface of the flower pot, which can prevent snails and slugs from eating the leaves of the flower. Because the edge of the egg shell is very sharp, these mollusks will make them feel uncomfortable when climbing over the egg shell, so they won't climb over to eat the leaves 2. Eggshell contains some phosphorus, calcium and iron. Mixing it with soil can provide some nutrients for plant growth, promote the development of flower roots and improve plant disease resistance

Cinnamon powder

1. Cinnamon powder, which can be seen everywhere in the kitchen, has good antibacterial activity. Therefore, when cutting, if there is no rooting powder at home, cinnamon powder can also be used instead, which can effectively reduce wound infection and increase the survival rate of cutting 2. Spreading cinnamon powder in flower pots or burying it in the soil has the effect of antibacterial and sterilization. It can not only kill some harmful microorganisms and insect eggs in the soil, but also avoid the harm of ants to flowers

Sand

1. Due to the high temperature in summer, a layer of sand can be paved on the surface of the basin soil, which can reduce the temperature of the basin soil, so as to prevent flower root rot caused by excessive soil temperature and some pests such as small black flies 2. Mixing sand and soil together can make the basin soil loose and breathable, with good drainage and avoid rotten roots. But be careful that the sand must be coarse sand. You can wash the sand several times, wash the soil in the sand, and then sieve the fine sand to get the coarse sand that can be used

Cinder

1. If there is a stove at home, basically there will be used cinders. After crushing the cinder, clean it with water. The large particles are screened out and padded at the bottom of the flowerpot, which is conducive to water and air permeability and prevent rotten roots 2. The remaining small cinder particles should not be wasted. They can be mixed with peat soil and used as nutrient soil. They can also play a role in loosening and ventilation and reduce the generation of plant rotten roots

Sawdust

1. Cutting is not easy to take root in summer. At this time, pure sawdust can be used for cutting, such as rose and gardenia, which not only takes root faster than soil and water cutting, but also the plant and sawdust can be moved into the flower pot when they are put into the pot without damaging the root system 2. Sawdust can also be mixed with soil after being decomposed to make nutritious soil. Raising orchids with sawdust can replace orchid mud, especially for the alkaline soil in the north, which can make orchids grow better (author: navigation source: China Orchid trading network)

Pine needle

1. Pine needles can be seen everywhere in the community. In fact, it is great to use self-made nutritious pine needle soil. Like making sandwich biscuits, a layer of soil and a layer of pine needles are piled up. Finally, it is watered once more, and then placed in the corner to wait for the pine needles to rot before they can be used 2. If you think it takes too long to use self-made pine needle soil, it is also good to directly collect the pine needles and pad them on the bottom of the basin, which can greatly increase the air permeability and water permeability of the flowerpot and naturally reduce the probability of rotten roots

Plant ash

plant ash is the residue left after plant combustion, which contains more potassium. When mixed with soil, it can not only provide potassium fertilizer for the growth of flowers, but also ensure that the soil is loose and breathable. But plant ash is alkaline, so it's better to use less
