Why do gardenia leaves turn yellow?

Gardenia in the breeding process at any time will encounter the phenomenon of gardenia leaves yellowing, then, why gardenia leaves yellowing? This is mostly due to the defects of management technology, water, light, fertilization and other aspects of improper management may lead to gardenia leaves yellowing, yellowing reasons for specific symptoms, together to understand the relevant knowledge.

Analysis on the causes of yellow leaves of Gardenia jasminoides

(1) the factor of improper moisture.

Gardenia planting process watering too much, then the young leaves will be dull, the old leaves will not be affected, but the leaves will be yellowish green, the new leaves are not long, the solution is: put the flowers out of the pot in a cool, ventilated place and then put them back into the basin. When there is lack of water, the tip or edge of the leaf is withered and dry, the old leaf is withered and yellow from the bottom up, and the growth of the new leaf is relatively normal, so it should be fully watered and thoroughly watered.

(2) the factors of improper illumination.

Excessive light leads to macula on the illuminated side of the leaves, which can be restored in a dark place. if the gardenia flower is placed in a shady environment for a long time, then the leaves will turn yellow or fall off because they do not get enough sunlight. It's best to replenish the light right away.

(3) the factors of improper fertilization.

Gardenia planting process should pay attention to fertilization, too much or too much concentration is easy to cause plant yellowing, new leaf tip will appear brown, general leaf hypertrophy and no luster, and concave and convex does not stretch, old leaves scorched yellow fall off. At this time, we should irrigate more and reduce the concentration of soil fertilizer. Lack of fertilizer will also cause plant yellowing, but the lack of nutrients in the plant is different, showing different symptoms.

① nitrogen deficiency: plant nitrogen deficiency simple leaves yellowing, new leaves small and brittle.

② potassium deficiency: when plants lack potassium, the old leaves change from green to brown.

③ iron deficiency: at the beginning, the leaves are yellowish or white, the veins are still green, and in severe cases, the veins are also yellow or white, and finally the leaves dry up and die. To this kind of situation, can spray 0.2% Mel 0.5% ferrous sulfate solution to prevent and cure.

④ magnesium deficiency: yellowing gradually develops from old leaves to new leaves, and the veins are still green. In severe cases, the leaves fall off and die. Can be sprayed. 7% one. 8% boron and magnesium fertilizer control.

⑤ phosphorus deficiency: the old leaves are purplish red or dark red.

(4) the factor of too low temperature. Too low temperature will also cause leaf yellowing, so in the process of gardenia culture, we should pay attention to anti-freezing in winter, early spring and early winter night should also pay attention to warm.

(3) the factors of improper fertilization.

Gardenia planting process should pay attention to fertilization, too much or too much concentration is easy to cause plant yellowing, the new leaf tip will appear brown, the general leaf surface is thick but not glossy, and the concave and convex does not stretch, the old leaves are scorched yellow and fall off. At this time, we should irrigate more and reduce the concentration of soil fertilizer. Lack of fertilizer will also cause plant yellowing, but the lack of nutrients in the plant is different, showing different symptoms.

⑤ phosphorus deficiency: the old leaves were purplish red or dark red.

(4) the factor of too low temperature. Too low temperature will also cause leaf yellowing, so in the process of gardenia culture, we should pay attention to anti-freezing in winter, early spring and early winter night should also pay attention to warm.

What if gardenia doesn't blossom?

Reason 1: improper water and fertilizer

During the growth period, excessive water and fertilizer caused plant growth, reproductive growth did not get enough nutrients, affecting the formation of flower buds, resulting in no flowering or few flowering, even if it could blossom, it was easy to drop flowers and buds. Excessive application of nitrogen fertilizer and lack of phosphorus and potassium fertilizer will affect flower bud formation. Therefore, attention should be paid to the application of flower fertilizer with more phosphorus and potassium fertilizer in the period of flower bud differentiation.

Reason 2: inappropriate lighting

Gardenia does not like strong light, but can not do without light, Jiaozi flowers like semi-overcast in summer and maintain in places with sufficient indoor light in winter. If the light is too strong or too weak, it will affect the blooming of the mast flower.

Reason 3: high salt and alkali content in soil

Jiaozi flowers like slightly acidic soil. The soil in the north is high in salt, so it will suddenly be alkaline, so planting will also lead to plant yellowing, which will eventually affect flowering. So it can be suddenly acidified before planting. It is better for the growth of gardenia.

Reason 4: no pruning for a long time

Gardenia branches are messy, long branches grow vigorously, disease and insect branches will also consume a lot of nutrients, when the branches are too tight, the leaves can not all carry out photosynthesis, but consume nutrients, which also leads to gardenia flowers do not blossom.

Reason 5: serious diseases and insect pests

When the disease and insect pests are serious, the gardenia plant is damaged, and the flower buds fall off by the disease and insect pests. Therefore, we should pay attention to insect control in the planting process.
