What to Do When Jasmine Leaves Turn Yellow: Causes and Solutions
Jasmine, also known as moli, xianghun, molihua, meili and so on, is an upright or climbing shrub of the genus Jasminum in the family Oleaceae. Its flowers are a famous raw material for scented tea and an important raw material for fragrances, and its flowers and leaves are used medicinally to treat red, swollen and painful eyes and have a cough-relieving and phlegm-clearing effect, but in actual cultivation the leaves often turn yellow. Let's take a look below at what to do when jasmine leaves turn yellow!
Alkaline Potting Soil
[Cause] When jasmine is watered with relatively alkaline water over a long period, the increased alkalinity causes iron deficiency, resulting in poor plant growth and yellowed, withered branches and leaves.
[Solution] Apply ferrous sulfate solution or alum fertilizer water to increase the soluble iron in the soil, and the problem will be solved.
Malnutrition
[Cause] When jasmine is grown in a pot, if the soil is not changed and fertilizer is not applied for a long time, the soil nutrients become insufficient and the leaves turn yellow.
[Solution] Change the soil promptly and strengthen water and fertilizer management, or simply increase fertilizer and water application.
Improper Fertilization
[Cause] When jasmine is given fertilizer that is too concentrated or organic fertilizer that has not been fully decomposed, it causes "root burn" and the branches and leaves turn yellow and withered.
[Solution] Remove part of the potting soil and replace it with new potting soil. In routine care, it is best to apply dilute fertilizer frequently rather than trying to feed it all at once.
Caused by Waterlogging
[Cause] If the potting soil of jasmine stays wet for a long time, lack of oxygen causes the roots to suffocate and rot, and the plant cannot absorb nutrients, so the leaves turn yellow and may even wither and die.
[Solution] Water alternately between drying and wetting; do not let the potting soil stay soggy all the time.
Unsuitable Temperature
[Cause] Jasmine is not cold-tolerant. If exposed to low temperatures, its normal internal physiological metabolism is disrupted, causing the leaves to turn yellow.
[Solution] Adjust the microclimate of the environment, add plastic film, or move it to a warmer place for care and management.
Insufficient Light
[Cause] Jasmine needs sufficient light during its growing period. In partial shade it can still maintain good condition for a while, but in a shaded spot it will soon show yellow leaves, withered tips and even leaf drop. Insufficient light generally affects flowering and normal growth.
[Solution] Adjust its position and increase the amount of light.
Pests and Diseases
[Cause] When jasmine is harmed by pests such as red spider mites and scale insects, yellowed and withered branches and leaves can also occur.
[Solution] Pay attention to ventilation and increase air humidity for prevention. When pests appear, spray promptly for control.
What to Do When Jasmine Leaves Turn Yellow: Causes and Solutions for Yellowing Jasmine Leaves
Many people like to grow a jasmine plant in their courtyard. If you run into the problem of jasmine leaves turning yellow during cultivation, what should you do? Below we will tell you the causes and solutions for yellowing jasmine leaves.
Causes of Yellowing Jasmine Leaves:
1. Alkaline potting soil: Watering with relatively alkaline water over a long period increases alkalinity and causes iron deficiency, resulting in poor plant growth and yellowed, withered branches and leaves.

Solutions for Yellowing Jasmine Leaves:
Generally speaking, if jasmine leaves gradually turn yellow during the growing period, it is mostly caused by alkaline water used for watering or alkaline potting soil; if the leaves suddenly turn yellow, it is often caused by root rot from excessive watering or overly concentrated fertilizer; if the leaf edges are withered, yellow and hard, it may be nutrient deficiency caused by insufficient watering and fertilizing or by not changing the soil for a long time. Based on the actual situation, identify the problem, check carefully and treat the cause accordingly.
How to Repot Jasmine: Causes and Solutions for Yellowing Jasmine Leaves
Jasmine is pure white and lustrous, with a fresh and pleasant fragrance, and is highly ornamental. Many people like to grow it in their homes. Next, we will explain how to repot jasmine, as well as the causes and solutions for yellowing jasmine leaves, hoping to be of help to everyone.
How to Repot Jasmine
Every spring, move potted jasmine outdoors, and in late April carry out leaf removal, picking off all the old leaves from the previous year. As the jasmine plant grows larger, the volume of a small pot and the nutrients in the potting soil can no longer meet the needs of root growth, so at this point it should be repotted into a larger pot in time. Small pots should be changed every year, while large pots can be changed once every 2 years. The timing can be in late April or early to mid-July, and water and fertilizer should be stopped before repotting.
Before repotting, prune the jasmine by cutting off broken roots, damaged roots and overly long roots, making the cut surfaces smooth, which helps rooting; then place the root ball of the plant in the pot, hold the plant with one hand, and fill in potting soil with the other, covering all the roots with soil, then lift the plant slightly upward. Do not fill the soil too full, so that watering is convenient. The potting soil is usually a mix of 4 parts compost, 4 parts garden soil and 2 parts fine sand. After planting, press the filled soil firmly, then water thoroughly once to help the roots and soil come into close contact and resume growth.
Repotting jasmine is an essential step in growing potted jasmine. Generally, clay pots are preferred, because clay pots facilitate drainage and aeration, which benefits root development and growth.
Jasmine is a strongly sun-loving plant that likes strong light. Except on windy days, it should be placed in a spot with ample sunlight so that its branches and leaves grow thick and strong and its flowers are plentiful and fragrant. Without enough light, the leaves become dry, wrinkled and yellow.
Jasmine likes a warm, humid environment. As soon as the soil surface dries out slightly, it should be watered. In hot summer weather, in addition to watering once a day, it is best to spray water once each in the morning, at midday and in the afternoon; too little watering will cause the leaf edges to dry up.
During the growth and flowering period from May to September, a liquid fertilizer should be applied once a week. Fermented soybean cake water, the first rinse water from washing rice, fishy water and so on can be used as top-dressing fertilizer.
Jasmine likes pruning. If you are unwilling to cut off some branches and stems, it will keep growing taller and become thinner and thinner. In this way, the nutrients it absorbs are used only for growing taller and it cannot produce flower buds. Therefore, after the flowers fade, be sure to prune the branches in time. Pruned branches will each grow a new shoot at the leaf axils on both sides. When the new shoots reach a certain height, flower buds will grow at the tips.
