Plants are very sensitive to changes in conditions, time of irrigation, the angle of incidence of sunlight, the change of fertilizers, the change of seasons, etc. So you need to constantly monitor their Pets to prevent possible unpleasant consequences. And if they still appeared, as for example, drying or tightening of the leaves, it is necessary to take appropriate action.
Causes of twisting of the leaf may be different. Wrong place in the room, lack of moisture, lack of certain vitamins and minerals, attack by insects, rodents, fungi and bacteria.
Too warm or dry indoor air leads to a twisting of the leaves of houseplants. Thus, the reduced leaf surface and evaporates less water, i.e. the plant conserves moisture. In this case, you must carefully water it and spray water from a spray bottle (if you have a plant, some cultures do not like) and then find a cool place with normal humidity level.
The same thing happens to garden plants during a heat wave, drought and strong winds. It is abundantly watered the trees and plants, but it should be done in the absence of strong heat, such as early morning or evening, otherwise the leaves will burn.
Twisting leaves could be a signal to growers about the lack of microelements, and in the form of a sheet, you can determine what exactly. For example, if the edges of the leaves curl inward, and the leaves take on the mottling, the plant lacks molybdenum. Curl up the leaves of plants depleted in zinc.
For calcium deficiency, the leaves begin to lose their bright color and wrapped down about a third of the length. Copper deficiency affected mainly cereals (wheat, oats), in this case their leaves are twisted into a spiral. Resistant to the loss of micronutrients is the potatoes.
The leaves may curl because of attacks of various pests such as fungus, virus bacteria, rodents (moles, mice). Small pests are transferred, usually aphids. With the spread of the virus leaves of damaged plants are twisted up, and in the deep phase of infection can be observed curvature of the tips of the undulation, lack of growth and other dire consequences.
Unfortunately, it is often to detect the virus at an early stage is not possible, so you need to periodically inspect garden plants and remove the root or tuber diseased individuals to the disease was not transmitted to their neighbours. Sick leaves indoor plants should be inspected thoroughly and immediately tear off diseased leaves from the bottom and treat the plant with a special solution or broth.
Rodents gnaw rhizomes of garden plants and eat the leaves. Most damage is caused by voles, which eat not only plants, but also carries the virus. Unfortunately, viruses are very resistant to adverse conditions, including winter weather, so to get rid of them is not easy.
Moles do not eat plants, but they feed on the insect pests of the garden and their larvae, therefore, may damage the plant's roots, laying itself a way under ground. To get rid of the furry pests, you can use smoke bombs (nor), rags soaked in kerosene, whirring turntables and electronic and ultrasonic traps.
The reason for the defeat of plants can also be a folly of gardeners who purchase plants without knowing its features. Thus, it is not possible to have care, green thumb does it by trial and often kills the plant. Therefore, you should be careful when buying unfamiliar, to take timely measures to protect the pet.
Advice 2: Why do leaves curl
Twisting leaves is a natural reaction of plants to the lack of moisture. Since the surface of the sheet, there is an intensive evaporation, the plant tries to save the precious liquid, reducing the area of loss. If you see that the leaves wilted and began to wrap in the tube – this is the first signal to check the moisture content of the soil clod. Dry plants should be watered abundantly, and, after some time, paraglide dried the soil to break the crust. Observance of the basic rules of farming and irrigation and mulching will help to avoid unpleasant consequences and to increase the yield.
However, twisted leaves can be a symptom of a disease associated with lack of soil nutrients. This occurs most often with a lack of nitrogen, potassium, magnesium, manganese and sulfur. Remember, when was the last time you contributed to the soil mineral fertilizers. If it was a long time ago, should be feeding a complex fertilizer which includes trace minerals. Just do not overdo it, do not think that if you pour more miserable starved tree will thank you. Excess of mineral substances cause severe burns of the root system and can cause severe illness and even death. Follow the instructions.
By the way, about the overdose. A very common cause of Curling leaves on fruit trees and agricultural plants are chemical burns pesticides. You recently were treated to protect your garden from harmful insects or fungus, but today noticed that all of the plant stand with twisted leaves? Most likely you overdid it and threw up the solution a little more concentrated than it was required by the regulations. Unfortunately, in this case in addition to wait for nothing. To restore burnt leaves you will not succeed.
Take a good look at the plant, which curl the leaves. Often the cause of this phenomenon can serve the pests. Aphids, whiteflies, wireworms and larvae of the scoop – they all damage the root system or the leaves and cause loss of moisture and General oppression of the plant. Carefully monitor their plantings and don't let the little pests destroy your crops.
Advice 3: Why do seedlings of eggplant rolled sheets
Generally, eggplant is a plant that is pretty well tolerated by all sorts of adverse environmental conditions, however, in the period of their stay in the premises of the torsion and poverty leaves can lead to death of seedlings. Therefore, if you notice that some leaves become slightly lighter, it is urgent to identify the cause of this and fix it, otherwise the plants will soon be able to curl the leaves that will lead to their death.
Often pallor and leaves twist eggplant says that they do not have enough light. If potted plants are in the back of the room, then move them closer to the window. Seedlings in any case should not be left under direct sunlight, otherwise the inevitable burns.
Also, the eggplant may not be enough water. Watering must occur two or three times in a week to defend water at room temperature. Remember, even with timely watering, the plant may receive less moisture, and the reason for that too the loose soil, which is not delayed water flows into the tray).
Inspect rolled leaves for better viewing, use a flashlight. If you notice a little light dots, remember this is a spider mite. In this case, will only treatment plants with special preparations from these pests.
To curl the leaves of an eggplant can from a lack of nutrients in the soil, especially if it is poor in calcium. If you have ruled out all of the above reasons, then swipe calcium fertilizing seedlings. Most likely this will be enough for the plants to gain strength.
If you transplanted the seedlings to the greenhouse, where there is enough light, moisture, nutrients, and other things, and the seedlings began to curl the leaves, in this case, will only the pouring of the soil with soft water (this procedure helps to remove excess salt). To do so, preferably before landing, otherwise, dig up the seedlings, slide the pouring, and after a couple of days again we will plant eggplants.
Advice 4: Why Anthurium blacken and dry leaves
Why dry leaves from houseplants and how to deal with it
The main reasons why the dry leaves of Anthurium, include the following:
- insufficient watering;
- too dry air;
- defeat the greenhouse aphids;
- Anthracnose, etc.
Typically, when bad watering and insufficient humidity leaf plates quickly wither and dry. The intensity of irrigation should depend on the time of year: in summer water the Anthurium should be abundant, and in winter reduce watering. Basic rule: between waterings substrate in the pot should dry on a 1/3-1/2 pot. The perfect humidity indicator for growing this houseplant is 85-95%. If to create such conditions, the leaves of the plant won't dry.
If the Anthurium does not bloom, the reason lies in insufficient light and incorrect feeding.
When Anthracnose leaf plate begins to dry from the edges, then the thinner the sheet, and after it dries completely. Treatment of infected plants is in the handling of its leaves systemic fungicide.
In case of defeat houseplants greenhouse aphid Anthurium leaves shrivel, twist, and covered with bright spots (this process is accompanied by abscission of the flowers). To get rid of pest affected plants treated with preparations "Malathion and Actellic".
The blackening of the leaves of Anthurium and combat this phenomenon
Causes blackening of the leaf plates:
- direct sunlight;
- inappropriate temperature mode;
- the predominance of calcium salts in the substrate.
Anthurium bad moves drafts: its leaves curl and blacken. Therefore, this indoor plant you want to move to another safe place for him.
Watering hard and cold water can cause the appearance of brown spots on the leaf laminas of Anthurium.
From direct sunlight Anthurium leaves turn black, that's why this houseplant is a must pritenyat. Ideally, this should be filtered sunlight or partial shade.
Too high or too low temperature will cause black spots on the leaf laminas of the plant. Indoors in the summer period, the temperature should range from 25 to 28C, and in winter - 17-19 ° Celsius.
On the presence of calcium salts in the soil evidence of limescale on the inside of the pot. In this case, we recommend to change the substrate (if you replace the soil completely impossible, at least to perform the substitution of top soil layer), thus enriching him with leaf humus or peat. In the future, houseplants need to be watered exclusively with soft water.
Advice 5: Why do leaves of tomato twist
One of the reasons for the twisting of the leaves tomatoes - the lack or excess of water. In this case, the foliage is twisted along its axis, forming a kind of boat. To help solve the problem of correct watering. In hot weather, tomatoes should be watered every evening, and will be cool enough to make it through the day. If there is insufficient water, the leaves are quite long - about two weeks.
With increasing air temperature up to +30-35 degrees and above tomatoes begin to consume more oxygen. For this reason, the collapse of the nutrients is faster. Simultaneously with this temperature regime the essential substances are much slower to absorb and accumulate. Because of this, the sheets are starving, which leads to their tightening.
To solve for this reason, the leaves of tomatoes can be sprayed with urea. To do this, dilute 2 tablespoons of urea in a bucket of water, and then spray the plants. Two days later, you can use a weak solution of potassium permanganate. As a rule, two days later, the leaves of tomatoes are straightened. If it's too hot, plants need to create artificial shade, using lutrasil, as well as to ventilate the greenhouse if the tomatoes grow in greenhouses.
The excess of fertilizer
Tomato leaves can curl under excessive content of fertilizer in the soil. In this problem the leaves are similar to a RAM's horn. If the curl of the leaves is complemented by the development of fairly powerful laterals, and thickening of the stem, this indicates excess nitrogen that harms fruit formation. In the end, the tomatoes increasing the green mass.
To reduce the amount of nitrogen will be sufficient once abundantly watered the tomatoes to wash the top layer of soil. It is important that the water is gone from the site, and does not stagnate on it. Otherwise, the tomatoes will suffer from excess moisture.
To reduce the amount of nitrogen in the soil will help the introduction of ash. You can sprinkle it right under the bushes of tomatoes.
Diseases of tomatoes
If the leaves of tomatoes curl down, this can indicate a bacterial defeat cancer. However, as a rule, the lower leaves turn brown and fade, and then completely dry up. On the lower part of petioles and stems are visible sores and cracks. If you cut the stem, you can see the brown ring of blood vessels, indicating that the bacterial. In this case, the plants can't be cured, they should be uprooted and burned.
Advice 6: Why are currants the leaves have turned?
Damage aphids are mostly red and white currants, black currants less. Colony insects are on the underside of young leaves and begin to eat. Leaves are deformed and blush. Be swellings (galls) that can cover almost the entire sheet.After a short period of time in hot weather even a few days, the maggots have a new generation of spread to other young leaves, form a new colony.
The species produces several generations in currants, then moved to the weeds, where it reproduces until the end of summer. Aphids in the autumn again returned to the bushes and "gives" to another generation of females lay overwintering eggs.
The pest overwinters on young shoots at the base of the cortex of the kidney, in the cracks of the old branches of a Bush. And in the spring, when blooming young leaves, aphids are once again beginning its life cycle.
How to protect your crop and get rid of aphids on plants?
In the spring spray the bushes in the leaves opening period. Use herbal infusions of chamomile, tobacco, citrus peels. After 10 days, repeat the treatment.
Proplyvaya the weeds around the bushes.
In severe cases aphids use handling any insecticide, follow the instructions.
And most importantly - make friends with ladybugs. These little beauties love aphids. During the day they can destroy more than 200 pest species.
