Almost everyone loves strawberries, both adults and children. Due to its early ripeness, it appears on the shelves of a store or in summer cottages before other berries, it is bought not only for a tasty snack, but also for obtaining such essential vitamins and useful substances in spring, weakened during the winter period.
But it often happens that strawberry bushes are affected by various infectious diseases and in the spring, the harvest is significantly reduced. Today we look at one of the fairly frequent problems that happens in the strawberry areas and see why the leaves turn red in strawberries.
Natural process
Reddening the leaves of a berry bush can be a completely natural process. Such a situation often occurs in the autumn period of time, when the amount of light received by a plant decreases and the light day decreases.
If such a situation has occurred, then no processing is necessary, you can just mow the reddened leaves, where new green leaves will appear in their place.
Causes of redness
The reasons for the appearance of red leaves on strawberries are not few, they can occur both due to improper care of the plantation and the plant, and under the influence of pathogens.
Very often the cause of the formation of red spots on strawberries is infection. Suspicious is the fact that the leaves turn red not completely, but selectively and pointwise.
Learn how to deal with brown spot, fusarium and verticillous wilting of strawberries.On one leaf there can be many small spots, which over time acquire a brown shade and can lead to complete wilting of the foliage. When the fungal spores have spread enough, they can be seen on the lower portion of the strawberry leaf.
When a fungal disease occurs, only treatment with the help of special means will help; after all, there is no hope that with the onset of cold weather the fungus will die out. His disputes easily overwinter in the ground, and with the onset of spring heat they will grow with new force and hit the plantation until all the strawberry bushes are inhabited.
The peak point of growth of fungal infection is the period of formation of the ovary on the bushes, and therefore there is a significant reduction in yield.
Did you know? In fact, if you turn to science, the fruit of strawberries is not considered to be red sweet flesh, but those yellowish "seeds" that are located on the receptacle, which we habitually call the fruit of a strawberry bush.To combat fungal infection, it is recommended to use Bordeaux liquid at the rate of 1 l of product per 10 sq. M. meters Spraying the bushes of the plant is necessary when the mass growth of new young leaves begins.
Also a fairly effective tool is considered "Chorus". To prepare this tool, you must use 12 g of the drug per 10 liters of water. Use the solution for spraying plants in the period of active growth of young leaves.
Next, after the bush has flowered, it is necessary to make the solution again, but now use 6 g of the product per 10 liters of water and re-spray it.
Important! It must be remembered that when processing strawberries with any chemical preparation, it is necessary to wait a period of 30 days before consuming the berries from the cultivated plantations.
Fertilizer shortage
There is the possibility of red spots on the leaves of strawberries due to the lack of nutrients, this problem is also called nitrogen starvation, so consider what to do in such a situation to save the plant. In order to normalize the condition of the plant and resume its normal diet, it is recommended to feed a balanced set, which will contain mineral and organic components.
You can prepare such a mixture yourself; for this, take a third of a bucket of humus and a teaspoon of mineral supplements containing potassium in an overwhelming amount. The resulting mixture should be well mixed and pour the rest of the bucket with water.
The fluids will take 3 days to mature and you can start feeding the plant. For the implementation of feeding you should pour a bucket of water at room temperature and stir in it 1 l of ready fertilizer.
Watering strawberries should be careful that the liquid does not fall on the bushes. Those leaves that have changed color are recommended to be cut off, where young and green leaves will appear in their place.
Did you know? The cultivation of strawberry bushes occurred in the 15th century on the Iberian Peninsula. Berry has caused a sensation among the population and at a crazy pace spread throughout Europe.
Thickened landing
Another common cause of the reddening of the leafy part of strawberries is the thickening of planting bushes, which happens if the necessary regular care for the plant is not available.
In order for the plant to develop normally and abundantly bear fruit, it is necessary to provide him with proper care. To do this, in the spring, remove all dead parts of the plant. You should also clear the area from the top layer of soil. Row row dig and burst.
We must not forget about the care of strawberries in the autumn. Particular attention should be paid between the rows. Planting thickening occurs due to the active growth of strawberry bushes and it simply does not have enough free space.
To avoid this, scoop up the newly formed bushes and plant them in the right place. Thus, you will thin out the thickened areas and plant some new bushes, which will soon bring you additional harvest.
Preventive action
As a preventive measure for leaf redness, you can:
- Laying a new planting of strawberries on fertile soil, well-lit and ventilated place.
- Prevention of thickening of the territory where plants grow bushes.
- Removal of diseased, reddened leaves of the plant.
- Cleaning the area from weed vegetation so that the bushes receive the necessary air circulation.
Important! Removal of leaves should occur in the spring, when the plant has already formed a leafy part. Also, the leaves can be plucked after the harvest.Thus, it is not difficult to resist the redness of leaves in strawberries, the main thing is to identify the cause of this problem in time and choose the right method to prevent its further development.
