Tolerates a pH in the range 4.3 to 8.3. Plants are intolerant of water logging. When growing plants in pots, a compost comprising equal quantities of loam and leafmould plus a little charcoal should produce good results. Do not use manure since Citrus species dislike it. When watering pot plants it is important to neither overwater or underwater since the plant will soon complain by turning yellow and dying. Water only when the compost is almost dry, but do not allow it to become completely dry. The sweet orange is widely grown for its edible fruit in warm temperate and tropical zones, there are many named varieties. In Britain it can be grown in a pot placed outdoors in the summer and brought into a greenhouse during the winter. Plants are almost hardy in the mildest areas of Britain but the fruit is insipid if it is developed when the mean temperature is below 18°c. The young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun. The flowers are sweetly scented. Plants dislike root disturbance and so should be placed into their permanent positions when young. If growing them in pots, great care must be exercised when potting them on into larger containers.
