Why are strawberries sour and how can you fix it?
Strawberries are considered one of the most popular horticultural crops; in the home gardens and summer cottages of our compatriots, they have been steadily occupying a leading position for many decades.
This berry is loved for its color, aroma and, of course, a delicate sweet taste with a slight sourness. However, sometimes situations arise when there is too much acidity. Let's understand the reasons.
Why are fruits not sweet?
There are many reasons why berries grow not sweet, but sour.
The first reason is related to the wrong variety. It happens that when transplanting their bushes to a new place, the gardener simply confuses plants of different species and then is surprised to find that those berries that should be sweet turn out to be completely different. To avoid such confusion, you should be more careful and sign the seedlings when changing the landing site.
The second reason is too long growing time and natural aging of the shrub. It is believed that strawberries need to be renewed every 4-5 years; if it grows in one place longer, then the berries invariably shrink, and their taste loses its sweetness and aroma. This is easily explained - the root system wears out over a long time and is no longer able to provide either the proper size or the favorite taste of strawberry fruits.
The fifth reason is related to the height of the strawberry planting.If you are the owner of uneven land with slopes, moisture stagnation often occurs, which significantly impairs the taste of berries and the development of strawberries in general. In this case, it is worth equipping raised beds, leveling them on the surface, and you can enjoy a good harvest.
The sixth culprit in low sugar levels in fruits is also beds, but this time they are located incorrectly in relation to sunlight. Strawberries love the light and the most delicious fruits grow in the sun; in order for the fruits to fully ripen, they need at least 8 hours of natural light per day.
High temperature and sufficient light are the key factors affecting the quality and quantity of cultivated garden strawberries.
The third reason is excess watering. Of course, if the summer turned out to be rainy, then you can’t do anything here, the only advice is to loosen the ground near the bushes and aisle as often as possible, this will allow moisture to evaporate faster. But more often the gardeners themselves are to blame - out of ignorance or in pursuit of the size of the berries, they flood their plantings. As a result, the berries become watery and completely tasteless.
The fourth reason is related to the characteristics of the soil. The fact is that strawberries prefer fertile and well-drained lands, slightly acidified. If you noticed that in the current season strawberries have slightly changed their taste and become more acidic, then in the spring, be sure to feed the land with compost or rotted manure mixed with river sand in equal volumes - dilute with water and thoroughly pour the resulting solution over the entire area where growing strawberries.Such processing can in no way be attributed to full-fledged top dressing, however, it is noted that the fruits actually turn out to be sweeter and rather large.
The seventh reason is high planting density. It seems to some owners of summer cottages that the more bushes they plant on one bed, the more they will harvest. This is not so - strawberries love space and need to provide a lot of space. The best option for planting berries on a plot is considered to be a square-nesting method, when the distance between shrubs on the same bed is 30-40 cm, and the row spacing is about 50. If the plantings are denser, then the bushes will feel a nutrient deficiency - in such conditions, berries are obtained small and sour.
Another reason is cultural disease. When buying bushes, inspect them most carefully - there should be no signs of rot, mold and spotting on the leaves and shoots: all fungal infections cause plant depletion, which at best causes a loss of taste characteristics of the fruit, but most often leads to the death of bushes. Such a preventive examination should become mandatory from year to year.
The ninth factor, which often leads to an increase in acids in fruits, is the wrong planting date. It is advisable to plant garden strawberries in August, but many do this when they feel like it, which is fundamentally wrong. Strawberries should be planted in the last summer month, because only in this case, before the onset of cold weather, does it have enough time to build up the necessary root system.If you live in a temperate climate, then before the arrival of frost, you also need to mulch the ground or cover it with agrofiber - then the young bushes will be able to survive the winter, and the fruits will turn out juicy and sweet.
The tenth reason is related to excessive haste. Do not expect in the first year - immediately after planting - a plentiful and sweet harvest. Let the plants gain strength and energy - then in a year you will be able to enjoy the delicate taste of berries.
And finally, the taste of the berries is significantly reduced if gardeners resort to mowing at the end of the season in order to remove all leaf plates from the site. Most often, as a result of such actions, damage is caused to the growth point and this provokes deformations that lead to a decrease in the sweetness of strawberries. All leaf plates are best combed out with a small rake.
How to improve the quality of berries?
If you notice that strawberries have become more sour - do not despair. In most cases, the situation can be corrected and enjoy delicious fruits next season.
- Give the plant light. It has been proven that the aromatic compounds that give strawberries their distinctive flavor are very closely related to the amount of light the plant receives. Scientific studies have confirmed that if you triple the lighting, the sweetness of the fruit also increases.
Scientists have calculated that the presence of sugar in a berry growing in the shade is 7 times lower than that of one planted in a sunny place; therefore, if your berries develop near a fence or in the shade of a sprawling tree, just transplant them to a new place where they will not lack light and warmth.
- Give me more red. Surprising but true.Plants mulched with red fiber produce fruits that are 20% larger than the rest, as well as much sweeter and more fragrant. This is confirmed by data from studies conducted at the University of California at the beginning of this century. Under such conditions, more ascorbin and anthocyanins are produced in the berries, which are responsible for the coloring of the culture.
- Provide potassium to strawberries. Experiments conducted by breeders have shown that plants grown on acidic soils with a high content of potassium have a much sweeter taste. If you live in regions where the land cannot boast of such parameters - just make raised beds with a high amount of organic matter, for example, peat and compost; also, apply potash fertilizer every two weeks throughout the growing season.
- Plant correctly. Proper planting gives half the sweetness of the berries. In order for the plant to please with a sweet and plentiful harvest, the distance between the seedlings should be observed, as well as regularly loosening the earth and removing weeds. It is optimal to pull out excess herbs immediately, as soon as they appear - this not only improves the taste of strawberries, but also significantly increases the content of vitamin C in it, and, therefore, makes the fruits more useful and nutritious.
- Comfrey and aspirin. Studies have clearly shown that the specific taste of the berry is due to the presence of the bacteria Methylobacterium extorquens, which live on the leaves. Their content increases dramatically if the plant is sprayed with infusion of comfrey, which is popularly called Adam's grass. To prepare such a composition, you should collect half a bucket of grass, pour water and leave for a month under a closed lid.For processing, 15 parts of water are taken for 1 part of the infusion, diluted and leaf plates are sprayed every two weeks.
Experienced gardeners note that if a crushed aspirin tablet is added to the resulting solution, the taste of the berries will improve significantly, and the ripening period will be reduced.
- Pick only ripe berries. In order to get truly mouth-watering berries, you need to pick them only when they are ripe, best in sunny weather and in the afternoon. It has been noticed that it is at this time that it is especially juicy and sweet, since the sugar level is elevated, and wateriness, on the contrary, is minimal. There are varieties that, even after they turn red, have not yet reached technical maturity, so consider the characteristics of the variety when harvesting.
- Use the mechanism of organic farming. Organically cultivated strawberries contain more antioxidants and beneficial vitamins than those cultivated using chemical farming techniques. The use of natural dressings allows not only to make the taste brighter and richer, but also more environmentally friendly and, accordingly, safe for children and adults.
Tips for Growing Delicious Strawberries
To grow a good crop of strawberries, you should follow the rules of agricultural technology. For the plant, weeding is very important. The culture does not tolerate competition, and if the plantings are overgrown with weeds, then the crop is sour and small.
Together with weeds, mustaches must also be removed, especially in spring - this will contribute to enhanced bud formation. Otherwise, all the strength of the plants will go into mustache formation and you will not wait for the berries.
Do not forget to loosen the plant, as garden strawberries prefer free access of air to the roots.These works should be carried out at least twice a month. Starting from the second year of the plant's life, the bushes should be hilled, as adventitious roots are formed in the near-stem zone.
Follow the watering regime. The plant needs water, especially in June, when both berries and mustaches are growing. Moreover, watering should be continued after harvesting, since at this moment roots and buds are formed for the next growing season.
If you properly care for the plant, feed and water it in time, then you will definitely get a good harvest of hard, juicy and sweet berries.
