Don't step on the yellow leaves of the rose to fatten the minefield.

July is almost halfway through. What are the masters most afraid of raising rose in summer? Yellow leaf is one of them. Recently, a flower friend asked the florist for help, saying that his rose had a new bud, the new bud was very strong, but it was yellow, and he checked the variety, but it was not a variety problem, so what was the problem? What should I do?

1. Yellow leaves of rose, lack of trace elements?

This is the rose in the flower friend's house. the new leaves are a little red, which is normal, but the leaves below you are not very yellow. Many rose friends say at a glance that this is a lack of trace elements, and they hurry to make up for it. The florist thinks that this may not be the reason. If it is a lack of trace elements, we can directly use the organic nutrient solution specially used for rose to fertilize.

two。 Yellow leaves of rose, one of the reasons

The little gardener asked the flower friend if he had applied fertilizer recently, and the flower friend said yes, then the problem came out. He just used fertilizer and the possibility of lack of trace elements is very small. Well, the yellow leaves of the rose are caused by the following two reasons. the first is because the fertilization is too thick and the rose is burned to the root, so it leads to the yellow leaves. At this time, it is best to change the non-fertile soil, otherwise it can not be saved.

3. Yellow leaves of rose, the second reason

The second reason is that the shade is not well done, and the strong old seedlings are fine to bask in the sun, so the young buds must not be able to stand the summer sun, and part of the reason for this yellow leaf is the high temperature. Therefore, when we are in maintenance, we have to prepare the sunshade net in summer. The gardener thinks that the two-tier sunshade net is safe to raise rose in high temperature areas.

4. Rose maintenance, using "science and technology" to measure fertilizer and water

Therefore, in the yellow leaves of the rose, do not always think that the problem of lack of trace elements, just changed the basin for half a year of the rose, how is it possible to lack trace elements, improper maintenance is the culprit. In the maintenance, how to judge whether the fat in the rose basin is excessive or not? You can measure it with a flower monitor, and it can also measure humidity and remind you to water it.

Rose masters, in the middle of summer, if your rose also appears yellow leaves like this, check to see if it is the above two problems, do not always think that it is the problem of "trace elements", blind fattening at this time will only kill the rose.
