How to Grow Orange Blossom in Pots? Detailed Guide to Cultivation Methods and Precautions

The orange tree is a common tree, and nowadays many people like to grow it as a potted plant, mainly because the orange tree is very beautiful when it blooms and has a certain ornamental value. Its flowers are small white blossoms, generally blooming in spring each year. So how much do you know about the cultivation methods of orange blossom?

How to Grow Orange Blossom

1. Temperature and light. Orange blossom is a fruit tree of the south, fond of a warm and humid growing environment, with a suitable growing temperature of about 12-37°C. It requires 4-6 hours of sunlight per day.

2. Soil. Orange blossom is not strict about soil; it is suitable to choose garden soil and mix it evenly with an appropriate amount of river sand, plant ash and decomposed organic fertilizer.

Cultivation Methods and Precautions for Potted Orange Blossom

I. Cultivation methods:

1. Watering. Keep the potting soil moist, and water thoroughly, preferably until water seeps out from the drainage holes at the bottom of the pot. At the same time, avoid waterlogging and drain promptly, otherwise it easily causes root rot.

2. Fertilizing. Adhere to the principle of “frequent application in small amounts”. Before the plant sprouts, apply a decomposed liquid fertilizer once, then apply liquid fertilizer about every 7-10 days, mainly nitrogen fertilizer, to promote its growth and the production of many spring shoots. During the growing period of orange blossom, you can sprinkle some cake fertilizer on the surface of the pot to enhance fertility. After autumn begins, gradually reduce fertilizing to avoid excess nutrients, which causes fruit drop. Strictly control fertilizing in autumn and winter.

3. Shaping and pruning. Because potted orange blossom has limited nutrients, pruning work and flower thinning and fruit reduction should be carried out in time. Generally, the pot and soil need to be changed every 2 years, combined with pruning.

II. Precautions:

When no frost damage occurs in winter, generally do not overwinter indoors; let it overwinter and go dormant naturally outdoors. To prevent frost damage, water thoroughly once before the soil freezes, then wrap the entire container with straw bags for cold protection, or dig a trench and bury it.

What to Do When Orange Blossom Leaves Turn Yellow

1. Water reasonably. Yellowing leaves of the orange tree may be caused by weather that is too hot and excessive water loss. At this time, appropriately increase the amount of watering; you can water once each in the morning and evening, and note that the amount of water at one time must not be too much. In addition, usually spray water on the leaves, or sprinkle water around the pot to increase air humidity.

2. Fertilize correctly. A lack of nitrogen fertilizer or boron fertilizer will make the leaves of the orange tree turn yellow, and at this time fertilizer containing nitrogen or boron should be applied. For nitrogen deficiency, you can apply farmyard manure or spray urea; for boron deficiency, you can apply boric acid; in addition, boric acid solution is also a good choice.

3. Change the soil quality. The orange tree is more suited to surviving in acidic soil; if the soil is alkaline, it may cause its leaves to turn yellow, or even drop leaves. You can mix a little beer into the water when watering, but be careful not to mix in too much. In addition, when choosing soil, choose fertile soil with relatively good aeration. If the soil is dug from the wild, put it in the sun to bake.

Common Pests of Orange Blossom and Their Control

1. Leaf miner. Control method: In spring, when new shoots sprout in large numbers and the shoot length does not exceed 1 cm, spray with the biological pesticide Bacillus thuringiensis 100-fold dilution for control; the effect is very good, and it can also protect the fruit. Omethoate emulsifiable concentrate 1000-fold dilution can also be used for spraying control.

2. Spider mite. Control method: During the occurrence period, spray with 0.3 degree lime sulfur mixture, or 40% dimethoate emulsion 1000-fold dilution, or 20% mite ovicide wettable powder 700-fold dilution for control, once every half month, spraying 3-4 times, with remarkable effect.

3. Citrus swallowtail butterfly. Control method: In winter, if overwintering pupae are found on the plant, they should be removed manually in time. Swallowtail larvae are relatively large and easy to find; when they occur sporadically, they can be caught and killed in time. During the larval occurrence period, spray with 90% trichlorfon technical material 800-fold dilution for control.

Growing orange blossom is actually not difficult; the main thing is to grasp its growth habits and then start from its growth habits. When growing it, be sure to pay attention to light and soil, and then manage fertilizer and water in a timely manner, so that orange blossom can grow better.
