Orange blossoms are not only very ornamental when they bloom, but they are not difficult to breed, so more and more people are starting to cultivate orange blossoms indoors. First of all, choose the loose and fertile garden soil as the potting soil, and then add the appropriate amount of grass and wood ash and other substances. Secondly, in the daily maintenance, water on time to keep the soil moist, implement the fertilization principle of "diligent application and thin application" to supplement the nutrients required by crops, and rationally shape and prune to balance nutrient distribution. Let's give you a detailed introduction.
Orange blossoms do not have high soil requirements, and cultivated orange blossoms can usually choose garden soil, and then add an appropriate amount of river sand, grass and wood ash and decomposed organic fertilizer to mix well.
Generally speaking, when watering, it should be watered thoroughly to keep the potting soil moist. In addition, the selected cultivated pots should have drainage holes, which can be drained in time to avoid water rotting roots.
Fertilization adheres to the principle of "diligent application and thin application", and applies a decomposed liquid fertilizer before the germination stage of orange blossoms, and then applies fertilizer every 7-10 days or so, mainly nitrogen fertilizer to promote its growth. During the growth period of orange blossoms, it is necessary to sprinkle some cake fat on the pot surface to enhance fertility. After entering the autumn, the fertilization should be gradually reduced and the amount of fertilizer should be strictly controlled.
Potted orange flowers have limited nutrients, and they need to change pots and soil every 2 years, and timely prune branches and leaves and thin flowers and fruits to regulate the rational distribution of nutrients in the tree.
Farmed orange blossoms are prone to yellowing of leaves, which may be the reason for the hot weather and excessive water loss, or the lack of nitrogen or boron fertilizer when fertilizing, and may also be the reason for the increase in soil pH. Generally speaking, excessive water loss increases the amount of watering to keep the pot soil moist; if there is no nitrogen fertilizer or boron fertilizer, a fertilizer containing nitrogen or boron is applied; and if the soil pH is raised, consider changing the soil or applying acidic substances to improve the soil.
