Yellow chrysanthemum is a picky flower, so you can take care of it on a general basis. Growing will not cause difficulties and problems.

The location of the flower should provide favorable living conditions.

In order for the chrysanthemum to please with gorgeous flowering every year, it is important to observe a number of conditions.

Chrysanthemum is a light-loving plant, but direct sunlight in the hot season can burn delicate petals. Therefore, when choosing a place for landing, this fact must be taken into account. An area with diffused lighting is great. Also in summer, when the air humidity is below 50%, the plant must be abundantly sprayed with water.

Chrysanthemum seedlings are planted in a pre-prepared trench at a distance of no more than 50 cm from each other. But it is also impossible to place it close - 30 cm of indentation is quite enough.

For the development of the root system and the strengthening of the plant, a biostimulating drug (such as "Kornevin") is used. The solution is diluted in the proportion: 1 g of the agent per 1 liter of water - and the soil is watered abundantly with it. Subsequent plucking of the plant will enhance the effect of Kornevin. To protect a young plant from adverse weather conditions, it is recommended to cover it with lutrasil (a special covering material).

As needed, the flower is fertilized, consisting of peat, humus and compost. And immediately after planting, the soil is fertilized with superphosphate.Approximately 2 weeks later, when the plant revives and gets stronger, the next stage of feeding the plant is carried out. For this, a mixture of potassium and phosphorus is used in a proportion of 45 grams to 25 grams.

Sometimes it becomes necessary to transplant a plant, but this should be done once every 3 years. In this case, each time it is necessary to exercise increased caution in handling the roots so as not to accidentally injure them.

Each spring, it is necessary to prune the upper part of the shoots. If the yellow chrysanthemum is small-flowered, then instead of pruning, a pinch is used. This procedure is done to create a lush bush. Remove all buds, except for the main ones, cut off the lateral shoots.

Most often, the plant suffers from gray rot, rust and powdery mildew.

Gray rot - a type of fungus that infects leaves and stems with dark brown, and then gray spots. This leads to the death of the plant. The cause of the disease is high humidity.

Powdery mildew - looks like gray-white droplets of bloom on chrysanthemum leaves, which interferes with the full flowering of the plant. It appears for two reasons: either an increased nitrogen content in the earth, or a lack of potassium.

Rust on the leaves - This is also a mushroom that covers the leaves with small yellow spots. Then the area of ​​distribution increases, and the yellow spots turn black. The destroyed leaves fall off, and the plant dies.

Aphid affects the plant even before it blooms. The pest infects the buds of the plant, the tops of the shoots and young leaves, that is, the most "tasty" and juicy parts of the plant.

Spider mite Is not an insect, but an arachnid animal. It sucks out all the nutrients of the plant along with the sap. It is not easy to find due to its small size. But the pest leaves a trail in the form of a thin cobweb enveloping the plant, which makes the leaves change color and look lifeless.

Nematode Are small and very thin worms that feed on chrysanthemum juice. They penetrate into the stems, leaves and develop there. The very first signs of a pest are dark, irregularly shaped spots on the leaves of the plant.

Treatment of yellow chrysanthemums is a simple process, especially if you notice a fungus or pest at an early stage of infection. Different methods are used depending on the cause of the disease.

Gray rot can be eliminated with antifungal drugs: Fundazol 0.1%, Rovral 0.15%, Ronilan 0.15% and Sumileks 0.1%.

Powdery mildew can be eliminated without even resorting to pesticides. The plant can be cured if it is systematically watered, provide access to sunlight and good air exchange in the soil.

Rust will no longer bother you if you fertilize the soil with phosphorus and potassium. The parts of the plant damaged by the disease are removed and burned, and the plant itself is abundantly treated with colloidal sulfur.

To prevent re-infection, once a week, each flower leaf is treated with 96% alcohol.

Heat treatment will help in the fight against the nematode. Pre-diseased leaves are removed and destroyed. The water temperature should be approximately + 45 ° C. In some cases, it is not possible to eliminate the pest. In this case, it is recommended to destroy the entire plant and the soil around it, otherwise neighboring plants may become infected.

In addition to the described methods of combating parasites, alternative treatment options are used. For example, watering the plant with a decoction of onion peels can eliminate aphids.
