Causes and solutions of yellowing of sweet-scented osmanthus leaves

Sweet-scented osmanthus is one of the top ten traditional famous flowers in China, and it is a famous variety of flowers. In addition, the fragrance is overflowing after blooming, the fragrance is rich but not prickly, and it smells refreshing. Therefore, many people like to put such a pot of flowers at home. But when we are breeding, we often encounter the situation of yellowing of leaves, which is actually caused by improper breeding. Today, the pro-farm network will introduce to you how the leaves of sweet-scented osmanthus turn yellow.

1. Improper watering leads to yellow leaves of sweet-scented osmanthus

Improper watering refers to too much or too little watering, both of which can lead to sweet-scented osmanthus yellow leaves. Too much watering will lead to stagnant water in the basin soil, lead to the decay of some fibrous roots, poor nutrient absorption capacity, resulting in yellow leaves, while too little watering is due to the fact that the water supply is less than the evaporation of the leaves, and the leaves are yellowed when the water supply falls short of demand.

Solution:

These two situations are completely different, so the ways to deal with them are also different. If it is too much watering, it is necessary to immediately control watering and fertilization, often loosen the soil to increase air permeability, and if serious, the plant should be removed from the soil and transferred to a relatively dry soil for re-cultivation; and if it is the yellow leaves caused by too little watering, it is necessary to move the flowerpot to the shade to reduce evaporation, at the same time, you can spray some water on the leaves, avoid pouring a lot of water into the soil, which can easily lead to plant death.

Second, soil alkalinity leads to sweet-scented osmanthus yellow leaves.

Osmanthus fragrans are more adaptable to the subtropical climate, where the soil is mostly acidic. If the soil is alkaline, then the cultivated sweet-scented osmanthus may grow poorly, the number of flowers will be greatly reduced, and there will be yellow leaves at the same time.

Solution:

Usually we spray 0.1% to 0.3% magnesium sulfate solution after planting to improve the acidic environment of the soil, or we can apply ferrous sulfate solution or small particles to the soil, which can not only make the soil slightly acidic, but also increase soil fertility and promote sweet-scented osmanthus flowering.

Third, improper fertilization leads to sweet-scented osmanthus yellow leaves.

Similarly, improper fertilization refers to too much or too little fertilization, both of which can cause the leaves of sweet-scented osmanthus to turn yellow. Excessive fertilization, especially too much nitrogen fertilizer and lack of phosphorus and potassium fertilizer, is easy to cause leaves to turn yellow. the specific manifestation of this situation is that the new leaves are thick, the leaves are mostly uneven, and the old leaves turn yellow and fall off gradually. while too little fertilization will lead to nutrition can not keep up with the growth of plants, showing thin branches and leaves, thin and yellow leaves.

Solution:

If you apply too much fertilizer, you should stop applying fertilizer immediately, increase the amount of water, let the fertilizer flow out of the drain hole, or directly replace part of the old soil, wash the soil block with water, and replace it with new cultivated soil for re-planting; if it is too little fertilization, you need to pour the pot in time, take out the plant, replace it with a larger pot, put it into a new loose and fertile soil, and replant it. After pouring water, put the seedlings in a half-light place to slow down. After its growth resumes, thin liquid fertilizer or compound chemical fertilizer is applied.

The above are the reasons and solutions for the yellowing of sweet-scented osmanthus leaves introduced by the pro-agricultural network, hoping to bring you some help. In addition to ornamental function, sweet-scented osmanthus can also be used as a raw material for making sweet-scented osmanthus tea. The tea has a pleasant aroma and is loved by many people. If you are interested, you might as well taste the sweet-scented osmanthus grown at home. It must have a special flavor.
