Garden strawberries, often called summer residents strawberries, is a perennial plant that tolerates winter cold and summer heat. On the one hand, in order to grow this culture on its site, it is enough to prepare the beds and place planting material on it. However, on the other hand, not everything is so simple!
Throughout the growing season, strawberries are exposed to many dangers: attack by pests, infection with viruses and fungi. No less fatal for her is the lack of nutrients. All these problems can negate the efforts of the gardener and repeatedly reduce the yield.
How to recognize that strawberries are sick
A healthy strawberry is always different from that which a pest or pathogenic microflora has posed for. It is possible to recognize that something is wrong with the landings by several signs:
- a change in the shape of the leaves - twisting, decreasing or increasing the plate, their deformation;
- discoloration of various parts of the plant - veins on leaf blades, stems, leaves, fruits;
- the formation on the stems, leaves and fruits of spots - dry and weeping, brown, red, white, with or without pubescence;
- absence, deformation or falling of ovaries and flowers;
- the appearance on the plants of a web, white foam (similar to saliva) or soot deposits;
- drying or wilting of parts of plants;
- death of plants located in close proximity to each other.
All these signs may indicate that the plantings are infected with some disease or have been invaded by pests, which have a lot of strawberries. At this point, it is important to find out why such changes occurred. Correctly diagnosed will help in time to save the landing.
Pests of garden strawberries
At the first stage of their activity, one can not even suspect the settlement of beds with strawberries with pests. Small, sometimes microscopic, insects can greatly weaken plants, which often leads to their death during the wintering period. No less dangerous are insects and the fact that they are often carriers of diseases. To preserve strawberry bushes and crops, it is important to detect traces of their activities in time.
Most often, the following pests inhabit strawberries:
Pests such as birds and wasps can also cause tangible damage to planting strawberries. To distract the former, between the ridges there are turntables with pieces of mirrors or foil, ratchets or red beads sprinkled before the berries ripen. Wasps are distracted from the ridges by banks with sweet syrup, placed in a distance from strawberries.

Garden strawberries are affected by rot, spotting and wilting caused by fungi and viruses. It is not difficult to see that the plants are “sick”, because rarely will anyone disregard the fact that the leaves or flowers of strawberries are yellow or covered with noticeable spots of red or brown color. Such signs should be a signal for action - the processing or complete removal of strawberry bushes from the site.
Most often, strawberries suffer from the following diseases:
Lack of chemical elements
External changes in garden strawberries can also occur with a lack of nutrients. Starvation in this case can be expressed not only in growth retardation in individual specimens, but also in a change in the shape of fruits and leaf blades, a change in their color and marketability. Many summer residents do not understand why strawberries turn yellow or red, because the soil is decontaminated, and the beds are regularly treated with special compounds from pests and diseases. In most cases, the answer is simple - she simply does not have enough food.
Find out what you need to feed strawberries, it is possible by the appearance of plants:
- nitrogen, if the leaves are pale and small, and fruiting is weak or absent altogether;
- phosphorus, if the old leaves are small and have a reddish tint, and the yield has decreased;
- potassium, if the leaves turn red along the edge, in the middle they become bluish, wrinkled, and the berries become smaller and lose their taste and aroma;
- magnesium, if the leaves change color to yellow, purple or red, while maintaining a green color along the veins, and the berries turn white and remain small;
- boron, if the leaf blades turn yellow, the veins on them turn red, and flowering and fruiting are absent.
During top dressing, you can not violate the recommendations set forth on the packaging by the fertilizer manufacturer, since an excess of nutrients and trace elements is as harmful to strawberries as starvation.
Avoiding problems: general recommendations
There are several rules that will help to avoid any problems when growing strawberries:
- Crop rotation. Strawberry beds are recommended to be transferred from time to time to a new place, and you can return to the old after at least 4 years. During this time, the causative agents of "strawberry" diseases have time to die in the soil.
- Timely watering and removal of excess moisture. Overdrying the soil, as well as its overmoistening, can provoke a surge in fungal or other diseases. To prevent either one or the other, it is important to water strawberries regularly, and to make beds more or less high so that they are blown by wind when the humidity is high.
- Maintaining soil fertility. Proper nutrition of strawberry bushes will strengthen the natural resistance of plants and increase the strength of their growth and productivity. It is important to annually add organic matter and complex dressings with microelements to the ridges.
- Keeping clean. Weeds and last year’s garden litter can be a source of infection or a house of pests. It is important from the autumn to thoroughly clean the site of weeds and tops, burning damaged fragments, and sending healthy ones to a compost pile.
- Compliance with landing standards. Having arranged the strawberry bushes too closely, the summer resident risks losing all the plants, because between them diseases and pests will spread faster. In addition, thickened beds are poorly ventilated, and plants lack nutrition.

Prevention is a very important point when growing strawberries in your own area. By taking timely steps to eliminate the risks of infection with rot or plant pests, you can completely save both the plants themselves and the crop.
