Orchids are easy to grow in summer

In summer, in the muggy heat, the weather is getting stronger and stronger, and it feels like a steamer. For orchids, a precious flower, summer is a kind of suffering. If you do not pay attention to the maintenance, it is easy to have problems, especially the "2 evils". If you encounter them and do not take timely measures, the flowering orchids will easily go bad.

1. Fertilizer damage

The symptoms of orchid fertilizer injury mainly appear in the leaves and roots. The occurrence of foliar fertilizer damage is usually when the foliar fertilizer is applied, coupled with the hot and dry weather, the water on the foliar surface is dispersed and unstable, which increases the concentration of fertilizer in the leaves, while the burned orchid leaves will appear chlorotic yellow spots on the foliar surface in severe cases.

Once the foliar fertilizer damage occurs, it is difficult to remedy. Therefore, in the application of foliar fertilizer, it is better to be light than concentrated. It is recommended to use liquid fertilizer for orchids, diluting 1000 times to spray leaves and watering roots, once a week. When spraying leaf fertilizer, do not spray into the leaf center, there will not be the problem of rotten roots and leaves.

Root fertilizer damage usually appears rotten root and empty root phenomenon after the application of thick fertilizer. After the occurrence of fertilizer damage in Langen, the orchid must be removed from the pot immediately. Soak the orchid root in clear water for 2 hours, after drying, put on the new special plant material for orchids and put it back on the basin; then soak the orchid pot in clear water for 1 hour, wash off part of the fertilizer by dilution and reduce the concentration. If it occurs in the high temperature season when it is not suitable to turn the basin, soak the original basin in flowing water for 1 hour.

2. Water damage

At noon in summer, it is often hot and dry, when the temperature is more than 32 ℃, the orchid stomata begin to close, basically enter the dormancy semi-dormant state, stop the normal metabolism. If the flower friends spray water on the orchid leaves at this time, the stomata of the leaves have been closed, and the water absorption capacity decreases, therefore, it can not alleviate the water transpiration of the orchid leaves.

At this time, spraying water, the environment humidity increases, high temperature and high humidity, it is very easy to breed germs; if poured into the leaf core, it is very easy to cause rotting heart to pour seedlings, and even cause soft rot. Moreover, the water droplets sprayed on the orchid leaves are like convex lenses, the sunlight shining on the orchid leaves will focus, and its focus will focus on solar energy, thus burning the orchid leaves.

At this time, the leaf surface of the orchid is easy to get black spots, and the diseased spot is very easy to be infected by bacteria, which makes the orchid get sick. Therefore, at noon in summer, flower friends must be careful not to spray water to the orchid leaves, you can spray water around the orchids, do not spray on the leaves.
