It was first bred in Europe in 18th century. Today, there are 600 varieties of this fruit that differ in size, flavor, and texture. Strawberry is a rich source of phenols that not only give berries their flush red color, but also serve as potent antioxidants that defend the cell structures in the body and prevent oxygen damage in organ systems.
It requires moderate amounts of nitrogen, phosphorus, and potassium content in the soil, from 84 to 112 kg per hectare, 56 to 84 kg per hectare, and 56 to 112 kg per hectare respectively. Unlike other plants, strawberry is shallow-rooted and tends to use nutrients available near the top of the soil.
The plant shows several clues when it needs fertilizers, like pale-yellow colored leaves, no berries, and no flowers, even though it may look green and healthy.
Fertilizers for Strawberries
After some time, the heat and moisture generated in the pile promote microbes to break down the organic material. The worms in the pile leave behind their casings and droppings, which add more rich and organic matter to the soil. Compost is the best soil amendment fertilizer and suits all types of garden soil.
Commercial fertilizers contain a chemical blend of all these three chemicals, with some trace minerals. The fertilizer bags display these three elements generally as numbers in a ratio, such as 5-10-5 or 10-10-10. The numbers show the percentage quantity for each element in the bag, with nitrogen as first, phosphorous as second, and potassium as the third.
For strawberries, one should always choose a balanced fertilizer with ratios like 5-5-5 or 10-10-10. Out of these two, the safest fertilizer is 10-10-10, which should be utilized about 2 ½ pounds for every 100 feet row of strawberries. Sprinkle it around the plants and follow the package directions.
Getting a soil test is a good idea to ensure that one is neither over-fertilizing nor under-fertilizing the plants. It is recommended not to cultivate the strawberry plant on the same land for consecutive years. Although strawberries are available throughout the year, their peak season is from April to July.
