Wood ash is an important fertilizer for houseplants. But do not overdo it.
Ash as fertilizer is nothing new. Due to the large amount of nutrients she is very popular among gardeners. The presence of potassium, sodium, calcium, magnesium and other elements contribute to the active growth and flowering houseplants, informs Rus.Media.
The composition of wood ash
To determine the exact composition of chemicals in wood ashes is very difficult because it is affected by age and the type of burning plants. In various types of wood ash can be a different composition. Wood ash is a fireproof organic remains, which consist of mineral substances. Most useful fertilizer for houseplants is the ash obtained from the combustion of plant residues.
The advantage of this ash is that the nutrients included in its composition not only readily dissolve in liquid but quickly absorbed by plants. Most of all it contains phosphorus, potassium, calcium, magnesium, sulfur, iron. There are also other minerals, but in small quantities.
In the ash of deciduous trees contains more nutrients mineral, compared with residues from coniferous trees. Therefore it is frequently used this type of ash. The remains of cereals and herbal plants include even more mineral elements than the products of combustion of hardwoods. Peat ash is characterized by the presence of a large number of lime and low in potassium. That is why such an ash is only used as a feeding of lime to reduce soil acidity.
The presence of calcium contributes to the normal development of green mass of plants in the early stages of development.
Due to this, the bushes are getting a balanced fertilizer during the whole period of vegetation.
Nitrogen in woody debris no. In the process of burning it evaporates. Wood ash used as fertilizer, as well as to modify the balance of the composition of the soil. This is beneficial to the reproduction of microorganisms in the soil, for example, nitrogen-fixing bacteria. The addition in soil of wood residues increases the resistance of plants to various diseases, promote rapid rooting when transplanting.
In any cases, you should fertilize with ash
All nutrients necessary for life of plants included in the organic composition of wood ash. The lack of one of them can affect the growth and development of the hive as a whole, and also lead to the emergence of the disease and the death of the plant.
Most wood ash contains calcium. This figure may reach 30-40%. With a lack of calcium in the soil from potted plants:
- deformed leaves, the curl up and the ends down;
- leaf color becomes white;
- crumble the stalks and this is especially characteristic of the family Solanaceae.
In second place, with a concentration in the composition of wood residue is potassium. Within the ash it is only 10-12%. In quantity it is inferior to calcium, but contains a sufficient proportion to the metabolism in plants was held correctly. The lack of this element strongly affects the appearance of the plant. There are the following signs of lack of potassium:
- indoor plants, such as roses do not smell;
- the leaves at the ends of solanaceous crops, dries up, and then collapses.
Methods of fertilizing ash
Top dressing of wood ashes does not cause any difficulties. It is possible to prepare a liquid solution for watering plants and use in dry and wet form. The most common use for ash is to add it to a liquid.
5 liters of water should take 50-75 g residue wood, mix well. To insist that the fertilizer is necessary for seven days. To ash rather gave their nutrient fluid, it is necessary periodically to stir the fertilizer. This infusion can be used to fertilize all the plants, watering the soil around the trunk. This dressing will help to increase the concentration of phosphorus in the substrate.
This method should also be applied if necessary to reduce the acidity of the ground, which can be achieved with calcium carbonate (18-36%).
Fertilizing ash has a positive effect for the geraniums, fuchsias and cyclamen.
Fertilizing will be paid directly into the soil when transplanting bushes. The ratio of soil and ash should be 2 tablespoons to 1 liter of the finished substrate.
It is recommended to use a fertilizer for houseplants in the form of a mixture of wood ash and residues of welding. This makes it possible to intensify the growth of the Bush in winter, to keep the color of the leaf plates and extend the flowering period of the plant. For preparation will need ash and welding in a 1:1 ratio.
Particularly the use of the ash for fertilizer
Despite the fact that wood ash is widely used for plant nutrition, the fertilization refers to the complex mixtures that have to be carefully combined with other types of nutrients.
- Do not add directly to the ash mineral nitrogen fertilizer. One month after feeding ash made nitrogen fertilizers.
- Mixing of wood residues with phosphorus can lead to the condition when the plant begins to absorb phosphorus is bad substance. Therefore it is not recommended to connect them.
- If you make ash into superphosphate, lime, manure, ammonium nitrate, urea and poultry manure levels of nitrogen reduced by almost two times.
- The superphosphate can be added to only 8% wood fertilizers.
- Allowed to use ash in conjunction with peat, compost and humus.
- For a uniform distribution of the substances, the ashes should be buried in the substrate. The depth should be 8-10 cm If you leave it on the surface, then regular watering it will form a crust that is harmful to houseplants.
- Interesting fact. 1 kg of ash can replace lime 0.5 kg, 0.22 kg of superphosphate and 0.24 kg of potassium chloride.
Since tree fertilizer affects soil acidity, it is not recommended for plants that have a high acid environment. Such plants include Rosalia, Camellia and others. How to make organic residues as fertilizer is not necessary. The increase in pH will decrease the absorption of nutrients plants from the soil.
In the event of a change in color ash brown rusty tinge to use it. This dressing contains a high concentration of iron compounds that helps slow the uptake of phosphorus. Any work with ash should be carried out in rubber gloves, it is desirable to cover the face.
Wood ash is an important fertilizer for houseplants. But do not overdo it. As with any feeding, fertilize the soil with ash it is necessary to efficiently. In this case, it is possible to achieve maximum effect for houseplants.
