This is the 917th day of the blue demon's daily original article.

Yesterday, the blue demon shared two basic points for attention about changing pots, but different flowers are often different, so there are more exquisite things about changing pots.

Friends who have bought azaleas, take a look at the bubble blue demon. I believe most of you have encountered such a problem.

After buying the azaleas and changing the pots, there is no problem. The flowers will also bloom. After the flowers are finished, they will gradually go wrong.

The leaves start yellowing and withering from the tip, and then the leaves begin to fall off, and some buds are scorched before they are opened.

At first, the tip of the leaf is dry and shedding, and then the development is that some of the branches are dry, and the leaves are almost bare, leaving only a few leaves at the top of the branch, which is still a little green and yellowing.

Flower friends who have encountered this situation, please raise your hand!

So why did this happen?

Many flower lovers will feel that their own pot soil is not good, caused by alkalization. Of course, this reason cannot be ruled out, but for cuckoos, which have only been bought for a few months, this is not the main reason.

Just think about it. Why didn't this happen when I bought it? The flowers are also in good bloom, but what about the problems after blooming?

In fact, this is a problem of excessive consumption of nutrients.

Why is there excessive consumption of nutrients?

To figure out this problem, first take your cuckoo out of the basin and have a look.

You will find that the cuckoo has no new roots at all, it is still the soil mass when you bought it, and there is no new and new growth in the newly added soil.

To put it bluntly, although we changed large pots with cuckoos, the roots of rhododendrons did not grow, and there was no new root growth, which is no different from us without changing pots.

The original soil mass is so small and the nutrients are limited. After flowering and consuming a lot of nutrients, it can be said that there are few nutrients left. In addition, during the months of maintenance in our hands, we repeatedly watered the soil masses, in which the fertility and acidity of the soil masses have been almost washed. So the cuckoo has yellow leaves and leaves fall.

Maybe you will say, I added the base fertilizer when I changed the basin.

Without the growth of new roots, the fertilizer in the new soil has no effect on the cuckoo.

So how can this be avoided?

To avoid this phenomenon of cuckoos, we must take precautions and take precautions when changing pots.

When buying azaleas, the cultivated soil is often peat or coconut brick, and the roots outside the soil are often dead fibrous roots.

When we change the basin, we should remove the soil and the dead fibrous roots from the periphery of the original clod.

Prune the roots until the living and healthy roots are exposed before planting.

In this way, the new roots will soon grow into our newly added soil.

You may be worried that if the root is damaged, will it not cause the rhododendron bud to fall off? Even the cuckoo will die?

We usually buy azaleas in late autumn or early spring, or even in winter, when the temperature is relatively low, the transpiration of plants is relatively slow, and some root damage does not have a great impact on plants.

This is why most of our potted plants choose to change pots in autumn and early spring.

So don't worry at all, root pruning will lead to the death of azaleas. On the contrary, if you do not prune the root and plant it directly, the new root will not grow, it will feed you very much, and it will only wither in the end.

Azalea is a special kind of potted plant, so the blue demon is listed separately.

Most potted plants do not need to be operated in this way, but they should be treated differently according to the situation. Tomorrow, we will continue to share several common situations and coping methods when changing pots.
