How Can a Tree Be Sweetened to Grow Sweet Fruit?

A tree that begins to produce sweeter fruit from sour and tart fruits can be made sweeter. The first step in making a tree sweeter is to increase its potassium or phosphorus content. Potassium controls the synthesis of plant sugars to generate delicious fruits and aids plants in using water and resisting drought. Potassium aids plants in better absorbing nitrogen from the soil and converting it to amino acids, which are then converted to protein. Fruit will have more sugar. Phosphorus aids photosynthesis by improving light absorption, which eventually fosters plant growth and reproduction. Add extra organic fertilizer, preferably wood ash, to the soil. primarily minerals and carbon. Fruit that faces the sun is sweeter than fruit that faces the sun from the rear.
