1. Variety Description<\/h2>\n

Name: <\/em><\/h3>\n

Tao Dai apple belongs to the Rhamnaceae family.<\/p>\n

The apple trees currently sold at the center are grafted varieties, allowing them to bear fruit within 12\u201318 months after planting.<\/p>\n

Characteristics:<\/em><\/h3>\n
    \n
  • \n

    Easy to grow and adaptable to all soil types.<\/p>\n<\/li>\n

  • \n

    High and stable yield, resistant to major pests and diseases.<\/p>\n<\/li>\n

  • \n

    If pruned early, the tree will bear fruit sooner the following year.<\/p>\n<\/li>\n<\/ul>\n

    \n

    2. Planting Techniques<\/h2>\n

    Planting Season and Spacing:<\/em><\/h3>\n
      \n
    • \n

      The main planting season is from February to April (spring). If early grafted seedlings are available, planting can begin in November.<\/p>\n<\/li>\n

    • \n

      In favorable spring weather, trees grow rapidly and will bear abundant fruit by year-end.<\/p>\n<\/li>\n

    • \n

      Recommended planting distance: 3\u20134 meters between trees.<\/p>\n<\/li>\n<\/ul>\n

      Planting Holes and Basal Fertilization:<\/em><\/h3>\n
        \n
      • \n

        Hole size:<\/strong> 40x40x40 cm.<\/p>\n<\/li>\n

      • \n

        Fertilization per hole:<\/strong><\/p>\n

          \n
        • \n

          15\u201320 kg of well-decomposed manure<\/p>\n<\/li>\n

        • \n

          0.5 kg superphosphate<\/p>\n<\/li>\n

        • \n

          0.3 kg potassium<\/p>\n<\/li>\n

        • \n

          0.2 kg lime powder<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

        • \n

          Mix all fertilizers thoroughly with soil before filling the hole. Create a raised mound 20 cm above the ground surface (do not place the tree in direct contact with fertilizer).<\/p>\n<\/li>\n

        • \n

          If manure is unavailable, use 5\u20137 kg of bio-fertilizer per hole instead.<\/p>\n<\/li>\n<\/ul>\n

          Planting Method:<\/em><\/h3>\n
            \n
          1. \n

            Dig a small hole in the center of the mound.<\/p>\n<\/li>\n

          2. \n

            Place the seedling at the same level as the mound\u2019s surface.<\/p>\n<\/li>\n

          3. \n

            Cover the roots with soil, compacting it around the base.<\/p>\n<\/li>\n

          4. \n

            Apply a 2\u20133 cm thick layer of straw mulch around the base.<\/p>\n<\/li>\n

          5. \n

            Water immediately with 2\u20133 scoops per tree (avoid watering if it rains).<\/p>\n<\/li>\n<\/ol>\n

            \n

            3. Care and Fertilization<\/h2>\n

            Watering:<\/em><\/h3>\n
              \n
            • \n

              In the first week, water once daily (morning or evening), using one bucket per tree.<\/p>\n<\/li>\n

            • \n

              After the first week, water every 2\u20133 days for one month.<\/p>\n<\/li>\n

            • \n

              As the tree matures, reduce watering frequency while maintaining soil moisture.<\/p>\n<\/li>\n

            • \n

              Apples require sufficient water during their growth phase. Drought conditions result in small, thick-skinned, and less flavorful fruit.<\/p>\n<\/li>\n<\/ul>\n

              Fertilization Schedule:<\/em><\/h3>\n
                \n
              • \n

                Annually, after harvest and pruning, apply per tree:<\/strong><\/p>\n

                  \n
                • \n

                  30\u201350 kg of manure<\/p>\n<\/li>\n

                • \n

                  5\u20138 kg superphosphate<\/p>\n<\/li>\n

                • \n

                  3\u20135 kg potassium<\/p>\n<\/li>\n

                • \n

                  0.5\u20131 kg urea<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                  Pruning Techniques:<\/em><\/h3>\n
                    \n
                  • \n

                    Proper pruning increases fruit yield and quality. Since apple fruiting branches grow from mother branches in the same year\u2019s spring, pruning should encourage strong, high-yielding branches.<\/p>\n<\/li>\n<\/ul>\n

                      \n
                    1. \n

                      Light Pruning (Annual Maintenance):<\/strong><\/p>\n

                        \n
                      • \n

                        Done yearly after harvesting to ensure stable and high fruit production.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

                      • \n

                        Heavy Pruning (Canopy Formation):<\/strong><\/p>\n

                          \n
                        • \n

                          Applied to young trees (1\u20133 years old) and older trees needing rejuvenation.<\/p>\n<\/li>\n

                        • \n

                          Cut back all branches, leaving only the base of three large branches from the previous year to form a productive canopy.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

                          \n

                          4. Pest and Disease Control<\/h2>\n

                          Common Diseases:<\/em><\/h3>\n
                            \n
                          • \n

                            Root Rot and Trunk Cracking:<\/strong><\/p>\n

                              \n
                            • \n

                              Symptoms: Sparse canopy, pale green leaves that fall prematurely, branches die back, and roots decay.<\/p>\n<\/li>\n

                            • \n

                              Prevention: Avoid excessive moisture around the root zone.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

                            • \n

                              Branch Dieback (Colletotrichum cloeosporioides fungus):<\/strong><\/p>\n

                                \n
                              • \n

                                Causes branch drying and death.<\/p>\n<\/li>\n

                              • \n

                                Affects mature fruits, causing soft rot.<\/p>\n<\/li>\n

                              • \n

                                Prolonged direct sunlight also contributes to this disease.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

                              • \n

                                Fruit Skin Disease:<\/strong><\/p>\n

                                  \n
                                • \n

                                  Fungal infection during fruit development causes small black spots that crack, reducing fruit quality and market value.<\/p>\n<\/li>\n

                                • \n

                                  Prevention: Keep orchards well-ventilated, remove debris, and apply preventive fungicide sprays after fruit setting.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

                                • \n

                                  Powdery Mildew on Leaves:<\/strong><\/p>\n

                                    \n
                                  • \n

                                    Minimal impact as it occurs when the tree is already fruiting.<\/p>\n<\/li>\n

                                  • \n

                                    Best prevention: Delay grafting until after September and avoid early pruning, as young shoots emerging in temperatures below 20\u00b0C are prone to infection.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

                                  • \n

                                    Fruit Rot:<\/strong><\/p>\n

                                    • \n

                                      Occurs in mature apples close to ripening, causing rapid decay (can affect all fruits on a tree within a week).<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                                              Common in apple orchards, causing tiny boreholes with white fungal dust around openings.<\/p>\n<\/li>\n

                                            • \n
