1. Site selection and fertilization

After bitter orange seedlings have grown for 3 years, choose a garden with well-drained sandy fertile soil and plant them around it (generally they are mostly planted around the perimeter of a citrus orchard). Dig holes at a plant spacing of 5-6 m. When digging the holes, keep the topsoil in the center separately, and apply fertilizer mud or other slow-release fertilizer as a base fertilizer.

2. Transplanting method

When planting bitter orange, the roots should be spread out so that they make contact with the soil at the bottom of the hole. In dry land, plant slightly deeper, then scatter the more fertile topsoil into the hole. When half of the soil has been filled back, gently lift the seedling so the root system spreads out and combines with the soil. After filling in the subsoil and firming it, water it.

3. Mounding soil and topdressing

Every year from September to November, mound soil around bitter orange according to tree size: 1000 kg for large trees and 500 kg for small trees. In February of the second year, open up the mounded soil. Fertilize once in early spring and once in early autumn. In early spring, use relatively thin water manure; in autumn, compost, lake grass or other slow-release fertilizer is suitable.
