Last Updated: 2024/11/24, When is it good to apply potash to apple trees? Please introduce that the timely and appropriate application of potash fertilizer in apple trees can not only increase the fruit size, sugar content, color, but also improve the internal quality such as bright color, smooth peel, flavor and taste. The absorption of potassium by apple trees is usually from early July to early August.

When is it good to apply potash to apple trees? Please introduce that the timely and appropriate application of potash fertilizer in apple trees can not only increase the fruit size, sugar content, color, but also improve the internal quality such as bright color, smooth peel, flavor and taste. The absorption of potassium by apple trees is generally from early July to early August. Applying an appropriate amount of potassium fertilizer to fruit trees during this period will get twice the result with half the effort. If the same amount of potash fertilizer is applied in early spring or before flowering, it will have no obvious effect on yield or chromaticity. The application amount of potash fertilizer for apple trees should be one kilogram of pure potassium per 100 kg yield. If excessive application, on the contrary, the physiological function of fruit trees will be damaged, affecting the absorption and utilization of other elements. Excessive application of potassium fertilizer in apple trees shows magnesium deficiency, and the content of calcium in the trees will be relatively reduced. In addition, when applying potash fertilizer, potassium sulfate with high absorption and utilization rate and obvious effect should be selected, followed by potassium chloride, and organic fertilizer with high potassium content such as plant ash or rotten chicken manure can also be sprinkled under the tree, and then watered in shallow burial. If 0.3% 0.5% potassium dihydrogen phosphate solution or 300-500 times potassium amino acid solution is used for foliar spray supplement, better results can also be obtained. 12 pruning methods for Apple trees Click to get more Apple Tree planting techniques Click to get more Fruit planting techniques
