Don't miss the second chance of firecrackers when the rose is fattening.

This is the 873rd day of the Blue Devil's daily original article.

Series of articles on the three-step method of rose culture: the 71st

These days the blue demon received the most advice is to ask how to prune after the rose, about the rose after pruning, the blue demon has been explained in the previous article, flower friends who do not know how to prune, you can look at the blue demon's historical articles.

What the blue demon wants to talk about today is the fertilization after flowering, in fact, the blue demon has also talked about it in the previous rose fertilization article, but there are still many flower friends who are not clear, now is a good time to fertilize the rose, so the blue demon will emphasize it again.

Rose official topdressing time: rose flowers before the summer, after the first crop of flowers, should be formal topdressing, and now is just after the first crop of flowers, is about to enter the summer time, the right time to topdressing.

The purpose of topdressing: this topdressing is mainly to provide nutrients for the blooming of the second stubble of the rose, while allowing the rose to store energy against the hot summer weather. What kind of fertilizer should be used? The topdressing of blue demon here is topdressing long-acting fertilizer, not quick-acting fertilizer. Quick-acting fertilizer should be applied frequently, probably every 10 days or so, while long-acting fertilizer is a continuous supply of fertility, which is different from quick-acting fertilizer. the relative frequency of application does not need to be so frequent.

Common long-acting fertilizers include fermented organic fertilizers, such as chicken manure, sheep manure, and inorganic fertilizers, which are commonly used as Ordovician fertilizer, which can be divided into slow-release fertilizer and controlled-release fertilizer. Both fermented organic fertilizer, slow-release fertilizer and controlled-release fertilizer belong to long-acting fertilizer, which can provide nutrients for rose for a long time.

But it should be noted that the fertilizer release of slow-release fertilizer is greatly affected by temperature, and the high temperature in summer is easy to cause fertilizer damage due to the concentrated release of fertilizer effect. Therefore, in this fertilization plan, Blue Devil recommends that you do not use slow-release fertilizer, if there is no organic fertilizer can use controlled-release fertilizer, it is relatively safer.

How to get fat? For potted rose, before topdressing organic fertilizer, you can dig out a layer of basin soil on the surface, then cover a layer of fermented organic fertilizer along the edge of the basin, and then fill the dug-out basin soil back and cover it. If the use of controlled-release fertilizer is the same as that of fermented organic fertilizer, it should be careful not to use too much.

Note: many people are lazy and sprinkle controlled-release fertilizer directly on the surface of flowerpots. In fact, this will cause some of the fertilizer effects to be lost, preferably shallow burial or burying. The cultivated rose should also be topdressing with long-acting fertilizer to replenish nutrients. First, the soil on the surface is dug out in the 20cm area around the root of the rose, and then covered with a layer of organic fertilizer, then filled back, and then raked to make the soil mixed with organic fertilizer.

The main purpose of this is to improve the soil and avoid hardening. Many flower lovers do not know the difference between long-acting fertilizer and quick-acting fertilizer, and do not dare to use quick-acting fertilizer after applying long-acting fertilizer. In fact, this is a wrong idea. After applying long-acting fertilizer to rose, you can still apply quick-acting fertilizer, and there is no conflict. The fertility of long-acting fertilizer is relatively slow and long-lasting, while the fertilizer effect of quick-acting fertilizer is very fast, usually 7-10 time, so the application frequency of quick-acting fertilizer is about 10-15 days.

Blue demon said so much, rose fat you will? Take action as soon as you learn it! If you have any questions, please leave a message for Blue Devil. Now the rose is pruned at the beginning, but it is smaller after the pruning. Flower friends who need it can buy it in the store.
