Feeding dahlia: the necessary substances and rules for making


Feeding for dahlias is an emergency measure for a starving plant. This is far from always necessary, but there are cases in which a plant cannot do without an additional diet.

What do dahlias need

Dahlia is considered unpretentious plant. For a normal life, he needs:

  • good lighting;
  • windless place;
  • fertile soil with good drainage and neutral reaction;
  • moderate hydration;
  • stable temperature without sudden changes.

Dahlia tubers allow the plant to develop a stem up to 1.5 m tall in 2 months, on which up to 10 large flowers of a wide color range manage to bloom by mid-summer. A quick start and good results allow you to grow dahlias even in extreme climates.

The main disadvantage of these plants is their complete intolerance to frost. However, this disadvantage can be wrapped in dignity. Proper storage of tubers allows you to provide your site with its planting material and a constant source for creative search.

Rapid growth, a large stem with rich green leaves, large bright flowers - all this requires very fertile soil and special care in providing mineral nutrition.

Problems in the development of dahlias and their manifestations

A healthy plant does not need additional nutrition. Excessive fertilization can harm both the soil and the plant.

Mineral fertilizers change the acidity of the soil, producing a shift of the scale towards the alkaline reaction, and contribute to the accumulation of heavy metals.

Mineral fertilizers are now available to everyone, and some gardeners think that dressing is mandatory. This, of course, is not true. A very simple rule is relevant here: if the plant looks healthy, then there is no need to intervene in its development. The health of a dahlia is determined by the growth rate, color and integrity of the leaves, the size of the stem and, most importantly, the abundance and shape of the flowers.

Signs of trouble with dahlias are as follows.

  1. Dahlias extended, the stalk is thin, the branching is weak, the growth is slow. This is a problem of poor lighting or lack of nitrogen.
  2. Despite the high stem and the abundance of leaves, few flowers are formed. This usually indicates a low content of phosphorus, potassium or manganese.
  3. Leaves are covered with spots and growths. This may indicate a deficiency in mineral nutrition, as well as the appearance of pests on your flowers.
  4. The buds form, but quickly dry out and fall off. This is usually an indicator of phosphorus deficiency.

So the dahlia shows the illnesses. Here are the main problems that await lovers of these bright colors. There are, of course, many more unpleasant surprises, but many of them are eliminated by feeding. The exception, perhaps, are pests, in the fight against which another chemistry is needed.

Dahlias: summer care and top dressing

Feeding for dahlias

Fertilizer for dahlias can be applied in the following ways:

  1. Manure or humus in preparation for planting is introduced into the soil before digging it. Pre-manure must be evenly mixed with the soil so that the dahlias fertilizers act indirectly. In this way, burns from too high a concentration of ammonia and urea can be avoided.
  2. Dahlias can be fed by periodic application of mineral complex fertilizers in the spring immediately after planting the tubers in the ground. A small amount of granules can be poured into the pit before planting, but it is better to put it on top of the ground, covering the newly buried tubers. When the dahlia starts up the tubers, the minerals will already dissolve in the rainwater and begin to flow to the roots.
  3. You can feed flowers and foliar way. This should be done if you see that something is wrong with the plants, and time is running out. Feeding is especially shown by spraying with mineral substances or growth stimulants when buds fall, irregular flowering (small flowers, asymmetrical shape, etc.) and other problems of an adult plant.

Feeding times can be different. For dahlias, mandatory spraying with a nutrient solution is usually carried out in early spring, when it is necessary to create favorable conditions for the start of tuber growth after winter, as well as during the flowering period. More frequent top dressing is done according to the situation.

In general, the rhythm of feeding is as follows:

  1. Spraying during the period when you need to reanimate tubers before planting.
  2. If you pour mineral water with the addition of manure roots, the dahlia will feel great 2 weeks after planting on the street.
  3. The first top dressing by spraying is carried out 10-14 days after irrigation with fertilizers.
  4. The second top dressing by spraying is carried out during the setting of buds.
  5. Sometimes there is a need to reanimate tubers, for example, when a dahlia does not tolerate winter and they begin to lose water or, conversely, rot.

Feeding solutions can be bought ready-made. Most often, a tool such as "Bud" is used, which is considered a universal stimulator of the formation of flowers.

In all other cases, it is recommended to prepare the following solutions:

  1. In 10 l of water add 1 tbsp. l urea, 1 liter of cow manure or 0.5 liter of bird droppings. Such fertilizer is poured under the root of a young plant at the rate of 1 liter per 1 bush. It stimulates the growth of green mass.
  2. For 10 liters of water put 1 tbsp. l "Agricola-7" and 2 tbsp. l urea. This solution is also intended for radical top dressing (2 liters per 1 bush).
  3. In 10 l of water add 1 tbsp. l "Agricoli-Roses", 1 tbsp. l superphosphate, 1 tbsp. l potassium sulfate. This solution can be used both for watering and for spraying.

Dahlias are plants that respond quickly to care. You will please them with fertilizers, and they will answer you with bright and large colors.
