Withered rose leaves are not a disease. After mending these little things, they will sprout and blossom immediately!

The new leaves turn yellow

Only a few days after some flower friends bought the new rose, the rose began to turn yellow from the "head", mainly new leaves, and the old leaves had nothing to do with it.

Reasons: 1, too much watering; 2, lack of iron element

Flower friends, according to the exclusion method, to see what kind of inducement is their own rose. Generally speaking, those who buy soil and go home will not be short of iron immediately. It may be that they are overwatered.

Countermeasures:

1. Reduce watering and re-water the basin soil when it is dry.

2. Pour ferrous sulfate solution or Amoy rice water for 1-2 weeks, mix it with 70% water, pour it in the basin soil, do not pour it on the rose.

The old leaves are yellow.

As soon as I saw that the leaves were so yellow, the flower friends were in a hurry. What should I do? Haha, I'm really in a hurry. There's nothing wrong with your rose.

Reason: normal metabolism, natural replacement of the new and the old

The rose grows fast, new leaves continue to emerge, and the old leaves at the bottom naturally "retire".

Countermeasures:

Remove the old leaves directly and do not leave them in the basin to avoid rotting and breeding bacteria and causing other pathological changes.

The tip of the old leaf is yellow and dry.

If the old leaves of the rose are not all yellow, but start yellowing and withering from the tip of the leaves, it is not natural aging, but lack of nutrition!

Cause: potassium deficiency

When the rose is deficient in potassium, not only the leaves are abnormal, but also the growth of the whole tree is not obvious, and it is relatively thin. In general, if there is more peat soil and sandy soil in the basin soil, it is easy to lack potassium.

Countermeasures:

1. Add some rotten leaf soil to increase overall nutrition.

2. irrigate potassium sulfate solution 1-2 times a month.

3. Remove the old leaves and don't put them in the basin to avoid rotting and breeding bacteria.

The leaves are yellow and uneven

If the leaves are yellow and orange, the veins are dark, and the leaves are undulating and undulating, it is also a lack of certain nutrients.

Reasons: magnesium deficiency and calcium deficiency

Generally, magnesium deficiency and calcium deficiency occur at the same time, the rose begins to grow poorly, or stops growing, and then the yellow leaves fall, so it is difficult to blossom at this time.

Countermeasures:

1. Pouring magnesium sulfate solution (water solubility is 0.1%)

2. Add 2-5 grams of bone meal to the basin soil every month; mix with crushed eggshells

3. Soak the soybean in water and pour it into the pot soil after 1-2 weeks of fermentation (0.2% concentration).

The leaves are all yellow

The long strong leaves are completely gone of green, even the veins have turned yellow, and the yellow leaves are still a little orange and red.

Reasons: lack of sulfur and nitrogen

Sulfur deficiency usually means that the upper leaves are yellow first, while nitrogen deficiency is that the lower leaves are yellow first. Flower friends can judge according to the position of the yellow leaves.

Countermeasures:

1. See whether the basin soil is loose and loosen the soil properly.

2. Remove yellow leaves and prune weak branches

3. Add nitrogen fertilizer, urea, and apply more thin fertilizer

4. Add manure and bean cake fertilizer

The leaves curled and yellowed

Some flower friends raise the rose well, the leaves are curled and yellow, and some even turn yellow on the edge of the leaves, which feel as if they have been burned.

Causes: 1. Hypertrophy; 2. Hypertrophic injury.

The leaves are still green and glossy, and the veins are dark, excluding insect pests, which should be hypertrophy or hypertrophic injury, which is not a good thing either. If it is serious, it will directly burn the rose.

Some flower friends wonder, my family did not fertilize, how to fat injury? It rains in some areas, resulting in an increase in salinity in the soil, which can no longer be absorbed by rose roots.

Countermeasures:

1. Stop fattening. If only a few leaves curl, water it a few more times to dilute the fertility.

2. If you compost, take out a little fertilizer properly.

3. For serious hypertrophy, it is best to change the soil directly.

4. fertilizer injury, remove the surface basin soil, temporarily control the water, dry the soil again, and change the soil directly in serious cases.

It's not that difficult to raise rose.

Mastered these little details.

If you have a seedling, don't worry about growing.
