Symptoms of lack of fertilizer in roses

The manifestation of missing different elements

During the growth process of roses, there will be more or less some problems caused by fertilization. Here the editor will tell you how the rose plants will behave differently when lacking different fertilizers, so that flower lovers can "prescribe the right medicine" to carry out maintenance.

Nitrogen deficiency

The signs of nitrogen deficiency begin to appear on older leaves. Specifically, there is uniform lack of green, the plants grow abnormally slowly, the leaves turn yellow, and in severe cases the leaves will fall off. Chlorosis symptoms start on older leaves and spread to newer leaves.

Phosphorus deficiency

The symptoms of phosphorus deficiency begin to appear on the older leaves. Specifically, it appears as an abnormal dark green color, sometimes accompanied by gray or purple spots. The color of old leaves turns blue and then slightly purple, the edges of the leaves turn purple-red, and the tips of the leaves will die.

Potassium deficiency

The symptoms of potassium deficiency begin to appear on the older leaves. Specifically, dicotyledonous plants will have mottled green areas, followed by necrotic areas along the leaf edges and tips, which will slowly curl until they become scorched and black. In monocotyledons, the cells at the top and edges of the leaves die first, and then spread to the bottom.

Calcium deficiency

The symptoms of calcium deficiency begin to appear on new leaves. Specifically, the tips and edges of young leaves will die first, followed by the leaf buds, and the root tips will then stop growing and change color, and finally die. The plant grows abnormally short and has dark, wrinkled leaves. Spots appear along the edges of the leaves.

Magnesium deficiency

The symptoms of magnesium deficiency begin to appear on older leaves. Specifically, there is a lack of green between the leaf veins and spots appear. Sometimes it will appear bright colors such as red and orange, and in severe cases there will be small areas of necrosis.

Sulfur deficiency

The symptoms of sulfur deficiency are similar to those of nitrogen deficiency. The leaves will uniformly lack green and turn yellow, and the growth will be abnormally slow. But the symptoms of sulfur deficiency usually begin to appear in seedlings.

Iron deficiency

The signs of iron deficiency begin to appear on young leaves. Specifically, there is an obvious lack of green between the leaf veins, and in severe cases it may appear burnt.

Zinc deficiency

The symptoms of zinc deficiency are abnormally slow growth of internodes and severe deformity of leaves. Striped spots on the leaves and lack of green on old leaves are also common manifestations of zinc deficiency.

Boron deficiency

The symptoms of boron deficiency are thickening of leaves, darkening of leaf color, and eventual death of the meristem at the top of branches and roots.

Manganese deficiency

The symptoms of manganese deficiency are lack of green leaves and small necrotic spots on both young and old leaves. But it should be distinguished from brown spot disease, bacterial spot disease, etc.

Copper deficiency

Symptoms of copper deficiency begin to appear on young leaves. Specifically, it is necrosis of leaf tips and withering and blackening of leaves.

Molybdenum deficiency

The initial symptoms of molybdenum deficiency are chlorosis and necrosis between the veins of old leaves, and some leaves will slowly die in spots.

Chlorine deficiency

The specific manifestation of chlorine deficiency is that the leaves first wilt, then become chlorotic and necrotic, until they turn bronze.

Although the article is long, it is full of scientific knowledge! This time, no matter which element is missing, I believe you will know which fertilizer to use to solve the problem, right? With little by little accumulation, even a "bricklayer" can become an expert!
