Culture methods of mallow

Soil

Mallow does not have very high requirements for soil, we can use slightly acidic rotten leaf soil or nutritious soil, sandy soil is also OK, when the sunflower is transplanted into the flowerpot, we should first put it in a position that can accept the sun and let it stay in the sun for half a day, which will be beneficial to the later flowering of the plant.

Light and temperature

Sunflower likes the sun very much, and it needs enough light during its growth period so that it can grow healthily. In addition, it likes to grow in a cold environment because it is more hardy. The most suitable growth temperature of mallow is between 18 ℃-25 ℃. During this period, it is necessary to ensure that the plant can receive sufficient sunlight every day. In winter, the temperature is very low, so it is necessary to keep the plant warm, put the plant indoors and be able to accept light for maintenance, and the temperature should be between 3 ℃-5 ℃.

Watering and fertilizing

The watering of the plant should be watered when the soil is dry, be careful not to water too much, so that there is stagnant water in the flowerpot, so that the root system of the plant is easy to rot, which is not conducive to the growth of the plant, especially in summer and winter. Because mallow has a lot of nutrients every time it blossoms, it also needs a lot of nutrients. In the growth period before flowering, we can apply compound fertilizer of nitrogen and phosphorus to the plant. In the process of plant flowering, we need to apply fertilizer based on phosphate fertilizer to promote plant flowering.

The above is the introduction of how to raise mallow. Let's take a look at what else we need to pay attention to in the process of marshmallow culture.

Culture methods of mallow

Malva is native to Asia, Europe and North America and is a biennial or perennial herb. Cold-resistant, drought-resistant, do not choose soil, sandy soil is the most suitable. Strong growth, like plenty of sunshine.

[planting] it is advisable to choose nutritious soil or rotten leaf soil with a PH value of 5.5 to 6.5 before the Qingming Festival, and put it in the sunny place for half a day after pot planting, so that the leaves can grow green and flowers, otherwise it will be difficult to bloom.

[fertilization] because the mallow blossoms for more times, it needs enough nutrition. From May to May, the fertilizer combined with nitrogen and phosphorus was applied twice, and blossomed from June to October. The fertilizer dominated by phosphorus should be applied twice a month to make the flowers bloom continuously.

[watering] in the midsummer high temperature season, the basin soil should be dry, avoid dampness and prevent rotting roots. Sometimes the leaves will fall, and new leaves will grow again the next spring.

[pruning] cut off withered branches, diseased branches, weak branches, over-dense branches and residual flowers and stalks at any time to facilitate ventilation and light. Single petals should also cut short and long branches to make them grow more lateral branches and blossom.

[anti-freezing and keeping warm] after winter, it should be moved indoors in time, put in a warm place facing the sun, and keep the indoor temperature 3: 5 ℃, which can survive the winter. the basin soil should be dry, avoid dampness and prevent rotting roots. Sometimes the leaves will fall, and new leaves will grow again the next spring.

[harvest and storage] harvested in summer and autumn and dried in the sun.

Culture methods and matters needing attention of mallow

Soil, the culture method of mallow

Mallow soil requirements are not high, you can choose sandy soil, or choose slightly acidic nutrient soil or rotten leaf soil, after the marshmallow pot, you need to put the sunflower pot in a sunny place for half a day, can promote its flowering.

Light and temperature

Sunflower likes the sunny environment, likes the cooler environment, can be cold-resistant. For breeding mallow, the suitable temperature for growth is between 18 ℃ and 25 ℃ to ensure plenty of sunshine. In the cold winter, the potted sunflower plants should be placed in a warm place with plenty of sunshine indoors, and the temperature should be kept at 3 ℃-5 ℃.

Watering and fertilizing

In terms of water and fertilizer, watering should pay attention to dry and avoid dampness, so as to avoid rotting roots, especially in cold winter and cool summer. Because the sunflower blossoms more and needs more nutrients, some nitrogen and phosphorus compound fertilizer can be applied during the growth period, and phosphate fertilizer is needed to promote flowering during flowering.

Reproduction method

The propagation of mallow is generally done by cutting and striping. Cuttings can choose robust branches, which will take root in a month or so. There are mainly two kinds of strip pressing method: high pressure method and ordinary pressing method.

Matters needing attention in marshmallow culture pruning

In the growth process of mallow, it is necessary to prune the withered, diseased and weak branches, dense branches and residual flowers, which is beneficial to ventilation and light, and promote the branching and flowering of mallow.

Diseases and insect pests and their control

Mallow in the maintenance process will appear some diseases, mainly coal fouling disease, can be sprayed with chemicals, and pay attention to ventilation to avoid diseases. Mallow sometimes encounters insect pests in the process of maintenance, mainly aphids and shell insects. When these pests occur in mallow, it can be sprayed with 2000 times the liquid of omethoate.
