2. Causes and solutions for the leaf edges of the lemon balm plant turning black

1. Indoor toxins too high

The greatest effect of the lemon balm plant is absorbing harmful gases, but if indoor toxins are too high, the lemon balm plant may also be unable to withstand it, thus showing symptoms of blackening leaf edges.

Solution: If the function is not enough, make up for it with quantity. At this time, in addition to moving the lemon balm plant outdoors for ventilation, you should also prepare more pots of lemon balm plants and absorb toxins at the same time! As for the source of lemon balm plants, the editor suggests that everyone propagate them themselves. As for how to propagate the lemon balm plant, there is a detailed introduction earlier, so I will not say more here.

2. Normal reaction

Actually, when the leaf edges of the lemon balm plant turn black, sometimes it is not a problem with care, because sometimes this is merely a natural growth manifestation.

Solution: At this time there is no need to worry at all. You can directly pick off the discolored leaves and throw them away. This will not cause adverse effects on other leaves.

3. Lack of sunlight

The lemon balm plant likes light, and its growth requires sufficient light. If everyone places the lemon balm plant in an overly shady environment, because it remains in an unsuitable environment for a long time, its growth will gradually weaken, thereby causing the leaf edges of the lemon balm plant to turn black.

Solution: Very simple, just place the lemon balm plant in a place with sufficient sunlight for care.

4. Dust accumulation

When the leaf edges of the lemon balm plant turn black, there is one cause that everyone very easily overlooks, namely that the leaves have not been tended for a long time, causing too much dust to accumulate on the leaves, which may be infected by pathogens present in the dust, thereby causing the leaves to turn black.

Solution: Immediately clean off the dust, and change a growing environment for this pot of lemon balm plant, then pay attention to daily leaf cleaning and management.

5. Insufficient nutrients

In addition to the above points, unreasonable fertilizer and water causing insufficient nutrients in the lemon balm plant is also one of the causes of the leaf edges turning black.

Solution: You can fertilize the lemon balm plant to increase its nutrients, but do not fertilize too much or too concentratedly. When watering the substrate, also water thoroughly when the surface soil looks dry.

6. Temperature too low

When the weather is cold, the lemon balm plant is also prone to the phenomenon of black leaf edges. Solution: Pay attention to light and warmth. In addition, when there are black leaves, just pull off the black leaves. They will slowly grow back well in spring.

Regarding the leaf edges of the lemon balm plant turning black, the editor has introduced this much. I believe that after reading this, when everyone encounters such situations again, they should know what to do! The key is not to panic, carefully observe the cause of the lemon balm plant's leaves turning black, and then treat the root cause. I believe that as long as you care for it carefully, everyone will definitely be able to grow a beautiful lemon balm plant.

What to do when the leaves of the lemon balm plant turn yellow? Supplementing light and increasing watering/appropriate fertilizing is key

The lemon balm plant, a very magical plant, is not only good-looking and highly ornamental, but can also absorb toxic gases. In daily life, many people grow lemon balm plants, but beginners often encounter yellowing leaves when growing it, which not only affects the ornamental value but in severe cases can also cause death. So what should be done when the leaves of the lemon balm plant turn yellow? The following are several causes of yellowing leaves summarized by the editor. Let's take a look together!

1. What to do when the leaves of the lemon balm plant turn yellow, find the cause

Because the lemon balm plant has strong vitality and is very easy to grow, many beginners do not grow it according to the cultivation methods for the lemon balm plant, so various problems often occur, including yellowing leaves. As for what to do when the leaves of the lemon balm plant turn yellow, the editor has summarized 5 points and attached solutions. Let's continue reading.

2. Causes and solutions for the leaves of the lemon balm plant turning yellow

1. Sudden environmental change

As for the causes of the leaves of the lemon balm plant turning yellow, there are actually many, but the first thing everyone should consider should be environmental factors. With the continuous rise of the internet, many flower lovers' lemon balm plants are now purchased online. Because of this, it is easy to cause a large regional span, and the lemon balm plant cannot adapt for a while, thus showing symptoms of yellow leaves.

Solution: At this time, everyone can communicate with the seller to learn about the growing environment of the lemon balm plant before purchase, and then create the same environment at home, then slowly change it until the plant completely adapts to the current environment. After a period of time, the lemon balm plant will recover its health.

2. Insufficient light

The lemon balm plant likes light, and its growth requires sufficient light. Once it cannot receive light for a long time, it will cause the leaves of the lemon balm plant to turn yellow. Generally, everyone should at least let the lemon balm plant bask in the sun once or twice a week.

Solution: Very simple, move the lemon balm plant to a ventilated place with light and care for it for a period of time and it will be fine.

3. Too little watering

When the leaves of the lemon balm plant turn yellow, in addition to the light factor, you should also consider that the plant is short of water. Although the lemon balm plant is relatively tolerant of drought, if it is not watered for more than 15 days, the plant's leaves will slowly turn yellow.

Solution: If it is short of water, we should replenish it with water. At this time we should water it slowly, and after a period of time water normally: watering once every half a month is enough.

4. Too little fertilizing

One more cause of the leaves of the lemon balm plant turning yellow is lack of fertilizer. If the leaves at the top of the plant turn yellow, that means the soil fertilizer is insufficient and cannot be supplied to the upper part, thus causing it.

Solution: Prune the top leaves in a timely manner, and maintaining a short but lush state is best; in addition, flower lovers also need to topdress in a timely manner. The amount does not need to be too much; proceed slowly according to changes in the plant.

5. Lack of necessary elements

In addition to the above points, there is another cause of the leaves of the lemon balm plant turning yellow, namely lack of necessary elements. If old leaves are green and new leaves are yellow, this is yellow leaf disease caused by calcium and iron deficiency; in addition, calcium deficiency will hinder the plant's nitrogen fertilizer synthesis, preventing new leaves from getting nutrients, causing nitrogen deficiency and the phenomenon of leaf yellowing.

Solution: If it is caused by iron deficiency, go to the flower shop to buy calcium magnesium phosphate, ferrous sulfate, and compound fertilizer. Mix a small amount of compound fertilizer with calcium magnesium phosphate and bury it in the soil, and spray ferrous sulfate on the leaves. For the specific amount, ask the flower shop owner. Another key point is to pay attention to maintaining ventilation. A non-ventilated environment can also easily cause leaves to turn yellow.

Like humans, plants can also develop problems due to improper care, so in order to avoid the above situations happening again, everyone must care for them carefully. Of course, if problems occur, do not panic; just follow the methods above. Regarding the leaves of the lemon balm plant turning yellow, the editor has introduced this much, hoping to bring help to everyone.

What to do when the leaves of the lemon balm plant turn black

The lemon balm plant can purify the air and is suitable for growing indoors. What do we need to pay attention to during the planting process of the lemon balm plant? Below let's focus on the planting of the lemon balm plant and see what to do when the leaves turn black.

1. What to do when the leaves of the lemon balm plant turn black——light and temperature

The lemon balm plant is a plant that likes light, and this plant is most suitable in places with sufficient light. When growing the lemon balm plant at home, if the light is poor, it will cause the leaves to wilt and turn black. So if the leaves at home turn black, the first thing you can try is to move the lemon balm plant outdoors and let it maintain sufficient sunlight exposure. The second is temperature. The lemon balm plant cannot endure low temperatures; at around 0 degrees it will no longer be able to survive, and excessively high temperatures are also not suitable for the lemon balm plant to survive. Unsuitable temperatures in summer and winter will inevitably cause the leaves of the lemon balm plant to turn black.

2. What to do when the leaves of the lemon balm plant turn black——dust and toxins

If the lemon balm plant is exposed to too high air toxins, it will also cause the problem of leaves turning black, because the lemon balm plant has absorbed too many toxins but has no time to expel them, so the leaves will turn black. Or because there is too much dust in the air, the dust covering the leaf surface will prevent the leaves of the lemon balm plant from fully absorbing nutrients or receiving complete light. If such things happen, then you can clean the leaves to help the lemon balm plant expel toxins.
