Iron deficiency in plants: natural iron fertilizers and home remedies: fertilizers

Iron is one of the most important minerals that a plant needs for healthy growth. But often it comes due to the soil or the wrong fertilization to an iron deficiency. Therefore, if the plant shows reduced growth or yellow leaves, immediate action should be taken. To provide the plants again with enough iron, also help various home remedies.

Symptoms of iron deficiency

Plants show typical symptoms due to iron deficiency. As a rule, fertilizers and soil contain enough iron to prevent a deficiency. But over-fertilization of nitrates, with a particularly humus-rich soil, an increase in pH to 7.5, for example, by pouring with very calcareous water can cause iron deficiency in the soil and thus also in the plant. Iron deficiency is recognized by the following symptoms:
  • yellow leaves
  • characteristic here, the leaf veins remain green
  • mostly young leaves affected
  • Growth disorders in case of long-term iron deficiency
Tip: If the iron deficiency is not counteracted in recognizing these symptoms, then the plants can in the worst case die off.

Often affected plants

There are certainly plants that manage with little iron and are therefore less often affected by iron deficiency. Other plants, on the other hand, require a lot of iron and therefore show the symptoms of iron deficiency faster. These include the following plants:
  • strawberries
  • blackberries
  • raspberries
  • roses
  • hydrangeas
  • magnolia
  • Rhododendrons and azaleas
  • apple trees
  • paprika
  • tomatoes
Therefore, especially in these plants should be paid to a low pH of 4.5 and thus an acidic soil, so that they have enough iron available.
Tip: Tomatoes are considered heavy tasters. Therefore, they require a particularly high demand for all nutrients to ensure a good harvest. However, if tomatoes are cultivated in mixed culture with other plants, it may well be due to the strong consumption of tomatoes to iron deficiency.

Prevent iron deficiency

The best thing is to prevent iron deficiency right from the start. Therefore, if the plants show the first symptoms of iron deficiency, then it is recommended to carry out a soil analysis. In this way it is determined whether there is a general iron deficiency or if the soil can deliver the iron only poorly. If there is a general iron deficiency, should be fertilized accordingly. If the iron absorption of the plant on the ground has only to be improved, then the following measures are suitable:
  • to loosen a compacted soil well
  • create a drainage against waterlogging
  • do not use calcareous irrigation water
  • better take collected rainwater for pouring
  • This prevents an increase in the pH of the soil
  • do not fertilize with nitrates or lime
If the soil is compacted or waterlogged, the plants can not pick up the iron that is still in the soil. This is because the iron is not water soluble and the plants first have to convert it. This is best achieved at a pH of 4.5.
Tip: Often potted plants are also affected by iron deficiency. This is mainly because many nutrients, such as iron, are flushed out with the irrigation water. It is therefore advisable to completely renew the soil in the bucket once a year, at the latest every two years.

Use coffee grounds

Coffee grounds against iron deficiency

If an iron deficiency has been observed on the plants, various home remedies can be used to iron the soil accordingly. This includes coffee grounds, which is mixed under the ground. Coffee drinkers in particular always have this natural fertilizer at hand. Although the coffee grounds contain no iron, it is slightly acidic and can thus help to lower the pH in the soil, which in turn favors iron absorption.

Stale beer

A very good fertilizer is stale beer. This contains because of the yeast containing in addition to the required iron and calcium, sodium, potassium and phosphorus. Therefore, beer as a fertilizer is not only recommended for iron deficiency. During fertilization, the procedure is as follows:
  • the beer should not foam anymore
  • therefore open the bottle
  • leave for a day or two
  • mix with water
  • as pouring water to the affected plant
Tip: Of course, it is not enough to fertilize the plant affected by the iron deficiency only once or twice with a home remedy. This should be given over a longer period at the beginning of the day, later every two to three days, until the plant has recovered. Thereafter, it is then normally fertilized every two to four weeks.

Green tea

Green tea is very healthy not only for humans, but also for the plants.Because this tea contains a lot of iron and is therefore very well suited for the continuous fertilization of raspberries and blackberries. Therefore, if a plant shows the symptoms of iron deficiency, then it should be fertilized with green tea as follows:
  • pour on and let cool
  • Dilute with water and pour the plant
  • If you drink a lot of green tea, you should keep the tea set
  • this is mixed underground

alum

Even the grandparents had alum as a home remedy for all kinds of things in the house. Whether for the tanning of skins, pickling of furniture or even for the nursing of bleeding wounds. Alum is available in the pharmacy and is today used by garden friends with hydrangeas to color them blue. But alum can also be used as a quick solution to iron deficiency in plants. The procedure is as follows:
  • Dissolve powder in water
  • Pay attention to the manufacturer's instructions for the quantity
  • then use to water the affected plants
  • Repeat every two to three days for several weeks
  • Then fertilize the plant again as usual
  • once she has recovered from iron deficiency

Foliar fertilization

Foliar fertilization, at the same time as home remedies, quickly eliminates iron deficiency. However, for foliar application, the special fertilizer must be obtained from a well-stocked specialist retailer. So the needed iron is taken up directly over the leaves. However, the home remedies can still be used as regular fertilizer. When foliar application but must be traded exactly according to the manufacturer. Otherwise, the leaves of the affected plants could take further damage in the form of a burn.
