House and garden plants – source of additional oxygen and delight for eyes. But what if leaves of the green pet have begun to blacken and be displaced in tubule? The reasons can be a little: the wrecker was brought, the plant has ached from lack of light or water, and can be to it the special leaving including fertilizers and water procedures is required.
Plants are very sensitive to changes of conditions, time of watering, incidence angle of sunshine, change of fertilizers, change of seasons, etc. Therefore it is necessary to watch constantly the pets to warn possible unpleasant consequences. And if they after all have appeared, such as, drying up or twisting of leaves, then it is necessary to take the appropriate measures.
The reasons of twisting of leaves can be different. Improper place indoors, lack of moisture, shortage of certain vitamins and microelements, attack of insects wreckers, rodents, fungi and bacteria.
Too warm or dry indoor air leads to twisting of leaves of houseplants. Thus, the leaf surface decreases, and from it less water evaporates, i.e. the plant saves moisture. In this case it is necessary to water carefully it and to oprysnut water from spray (if the species of plant allows, some cultures of it are not loved), and then to find more cool place with the normal level of humidity. The same happens to garden plants during heat, drought and strong winds. Follows it is abundant to water trees and plants, however it is necessary to do it for lack of strong heat, for example, early in the morning or in the evening, otherwise leaves will just burn down. Twisting of leaves can serve as signal for gardeners of the shortage of microelements, and it is possible to determine by form of leaf what. For example, if edges of leaves twist inside, and leaves get krapchatost, then the plant has not enough molybdenum. Up leaves of the plants which are grown poor by zinc twist. At the shortage of calcium the leaves begin to lose bright coloring and are wrapped from top to bottom approximately on third of length. Are subject to lack of copper, generally cereal cultures (wheat, oats), in this case their leaves twist in spiral. Potatoes are resistant to loss of microelements. Leaves can twist because of attack of various wreckers, for example, of fungus, virus bacteria, rodents (moles, mice). Small wreckers are had, as a rule, by plant louse. At spread of virus the leaves of the damaged plants twist up, and in deep phase of infection the curvature of tips, waviness, lack of growth and other sad consequences can be observed. Unfortunately, often it is not possible to find virus at early stage therefore it is necessary to examine periodically garden plants and to delete with root or tuber sick individuals that the disease was not transmitted them to neighbors. Sick leaves of houseplants also should be examined carefully and to immediately tear off sick leaves from the basis and to process plant special solution or broth. Rodents podgryzat rhizomes of garden plants and eat around leaves. Most of all harm is done by mice voles who not only eat plants, but also carry viruses. Unfortunately, viruses are extremely resistant to adverse conditions, including winter cold weather therefore to get rid of them not easy. Moles do not eat plants, but they eat insects wreckers of garden and their larvae therefore can damage plant roots, paving themselves the way underground. To banish fluffy wreckers, it is possible to use smoke grenades (for holes), the rags moistened with kerosene, chirring revolving objects and also electronic and ultrasonic traps. The reason of defeat of plants can become also rashness of amateur gardeners who buy plant, without knowing its features. Thus, behind it due leaving is not made, the gardener does it by method of tests and often ruins plant. Therefore it is necessary to be attentive upon purchase of unfamiliar look in time to take measures for protection of the pet.
