How to trim carnations? Three pruning methods make carnation flowers flourish.

Dianthus caryophyllus is a kind of ornamental plant, which is very suitable for planting potted plants and maintaining indoors or in the courtyard. When carnation is cultivated, besides reasonable maintenance, it also needs proper pruning. If you love flowers, pruning them is reasonable. About how to prune carnation, there are generally three methods: pinching and thinning buds, pruning residual flowers and re-pruning for winter.

1. Three methods of carnation 1 pruning: coring and bud thinning.

When the carnation plant grows to a certain height, it is necessary to remove the top edge, which can not only control the height of carnation, but also promote the growth of lateral branches. In addition, during the germination of carnation, it is necessary to properly remove the axillary buds of branches, which can greatly save nutrients.

Step 2 trim the residual flowers

The flowering period of carnation is May-June, that is, late spring and early summer. After flower failure, it is necessary to trim the residual flowers and branches in time, which consumes nutrients very much when flowering. Pruning residual flowers can save nutrients and promote growth. Pruning residual flowers means cutting with failure, and cutting which flower fails can avoid the waste of nutrients to the greatest extent.

Step 3 prune for winter

The last pruning of carnation in a year is from August to September, and the length of the pruned branches is only about 8 ~ 9 cm, so it is appropriate to cut off the growing points of most branches, which can promote the growth of branches and make plants take shape faster. This heavy pruning can also increase the drought resistance of plants and help Dianthus survive the cold winter.

Precautions for pruning

In order to prevent carnation from being infected with virus diseases, no matter how carnation is pruned, disinfection solutions such as carbendazim and chlorothalonil should be sprayed after each pruning. Tools used for pruning should also be disinfected, otherwise Dianthus can be easily infected with diseases.

Second, the maintenance skills of carnation 1 and proper watering.

Dianthus caryophyllus has a strong ability to adapt to the environment and is more drought-tolerant. Usually watering should not be too much, just keep the soil moist. Usually, carnation is watered every 65,438+00 days, but the watering frequency is subject to the actual climate and environment. Water the soil once when it is dry, and follow the principle of not watering, rather dry than wet.

2. Proper lighting

Carnation needs to keep enough light during its growth, otherwise it will lead to too many branches and leaves, and little or no flowering. It is best to ensure 6-8 hours of light every day, especially the mild sunshine in the morning and evening. In midsummer, carnation should be properly shaded to avoid sunburn.

Step 3 control the temperature

The suitable growth temperature of carnation is about 65438 05 ~ 20℃. If the temperature is too high in summer, carnation can be moved to a cool and ventilated place for maintenance, or sprayed with water to keep the plants moist and cool. It is best to move Dianthus indoors in winter, and the temperature should be kept above 12℃.

4. Rational fertilization

Dianthus likes fertilizer and needs a lot of nutrients in the growth process. Thin fertilizer water can be applied to it every 10 day, mainly nitrogen fertilizer. However, it is necessary to apply phosphorus and potassium fertilizer before flowering to promote flower bud differentiation and improve the quantity and quality of flowering.

Three. Dianthus caryophyllus 1 common pest control. rust

After the carnation is damaged by rust, rust-like spots will grow on the leaves and gradually spread to the whole plant, causing the plant to wither and die. After discovery, the diseased leaves should be removed in time, and then carbendazim solution should be sprayed for control.

2. Starscream

Red spider is a common pest of carnation, which will attach to the tender part of carnation and suck the juice, leading to the growth decline and plant atrophy of carnation. Artificial killing is difficult to completely eliminate pests, and appropriate omethoate solution can be sprayed for control.

Conclusion: After reading the above contents, I believe everyone should know the pruning method of carnation. It is not enough to trim carnation, but also to master the maintenance skills!
