Don't let your rose eat too much during the hot + dormant period

Rose likes fat, is a delicious host, it has strong compatibility, can accommodate a variety of nutrients, so "eat too much" will inevitably lead to fat injury, light growth stagnation, the heavy one will die. It sounds tough, but as long as we take proper precautions, fat injuries and so on, we all go far away.

In the last issue, we have described in detail the causes of fat injuries, there are many, external, the body, and the use of fertilizer, and the methods to prevent fat injuries correspond to these reasons one by one. As long as we avoid these minefields, there will be no fat injuries.

First of all, there is the problem of growing fertilizer. Specifically, we can refer to the previous article. As long as we do not apply raw fertilizer, the road that causes obesity and injury will basically be blocked.

The most important thing is the problem of fertilization. whether it is the method, time or seasonal characteristics, we should apply thin fertilizer frequently, pay attention to the frequency and diversification of fertilization, avoid long-term single use of fertilizer, and apply fertilizer reasonably according to the situation. it can be said that the probability of these fertilizer injuries is greatly reduced.

The plan is always unable to catch up with the change, we discussed very well, but it is inevitable that the horse has stumbled, the person has failed, if there is a fat injury, do you know how to deal with it? I don't know, it doesn't matter. I'll teach you the emergency treatment today. it's up to you whether the rose is stagnant or dead.

It is found that the first task after the fat injury of the rose is to reduce the fertilizer concentration as soon as possible, the unabsorbed ones are taken out quickly, and those that are already dissolved in the soil are washed away with heavy water to reduce the ion concentration and lose the excess fertilizer. When flushing, we should pay attention to the water permeability of the basin. If it doesn't work, you can poke it with a stick so that the fertilizer mixed in the soil can be washed off as much as possible.

After rinsing several times, you can use a tool hoe to loosen the topsoil, because it is not only too much fertilizer, but also too much heat caused by raw fertilizer, so loosen the soil quality and promote the rapid volatilization of harmful gases and the release of waste heat. Promote aerobic respiration and restore normal function of the root system.

The root problem has been dealt with, what about the nutrition that is absorbed and recycled to the whole body? We can spray the damaged leaves with clean water, wash the residual fertilizer on the leaves, cut off the diseased leaves when appropriate, and put them in a cool and ventilated place to slow down the seedlings. At the same time, pay attention to observe the humidity of the basin soil, and whether there is still heat left. If the basin soil is wet and feels hot, it is best to move to a place with better ventilation, lest the basin soil is too wet and cause rotten roots, and ventilation can also speed up the heat dissipation.

If the occurrence of fat injury is more serious, you can also use some rose-specific organic liquid fertilizer to help restore plant vitality and regulate physiological function, according to the proportion of use, dilution can be irrigated root.

Fat injury is very common, but does not mean that its lethality is also very common, now it is hot in summer, the basin soil is high in heat, coupled with dormancy, the probability of fat injury is greatly increased, so it is suggested that we should choose more foliar fertilizer in summer. It's safer this way.
