How to plant mallow and its planting methods and points for attention

Generally speaking, it is very difficult for plant seeds to go through the process of fire roasting, not to mention that the seeds will be burned to ashes after fire, and normal people will not use fire to roast plant seeds. However, mallow is such a strange species. Before the mallow is sown, we first need to bake its seeds with fire.

How to grow sunflower

Bake the seeds over fire until the shell bursts, allowing moisture to seep into the seeds and allow the buds to drill out. After sowing the seeds, cover the soil with one centimeter of soil and pay attention to keeping the soil moist. If you want to keep the mallow blooming, you need enough nutrition. Phosphorus-based fertilizer should be applied once a month, twice a month. Cut off diseased branches, weak branches, withered branches, over-dense branches and residual flowers and stalks at any time. In order to avoid its multiple lateral branches, single petal should also truncate short apprentices and long branches. It will also make mallow blossom more.

Planting methods and matters needing attention of mallow

1. Soil

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.

2. 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 ℃.

3. 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.

4. Methods of reproduction

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.

5. 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.

6. 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.

Reproduction of mallow

1. Cuttage propagation

Mallow can also use the method of cutting propagation, we first select a stronger mallow plant, cut a sturdy branch, about ten centimeters, retain the upper part of the leaves and terminal buds, cut the base of the cut branches flat, insert it into the prepared fine sand, pour appropriate water, and then place it in a shaded place, it will take about a month to take root. After rooting, it can be transplanted to the cultured soil.

2. Strip pressing method

In addition to the above two methods, we can also use the striping method to breed mallow, properly repair the branches close to the soil, then bury them in the soil, wait for a period of time, and wait until the branches buried in the soil take root. the secondary mallow branches can be cut off from the original plants and planted in the prepared soil, so that the propagation is completed.

Matters needing attention in fertilization of sunflower

The soil had better be dry before fertilization, then the soil can be loosened properly and fertilized, so that the plants can better absorb the nutrients in the fertilizer.

If the concentration of fertilizer is lighter, the time of fertilization can be shortened, and if it is thicker, it will be watered the next day, so as to prevent the accumulated fertilizer from harming the plants.

If you encounter cloudy and rainy days, you should appropriately reduce fertilization, or suspend fertilization, because too wet soil is very disadvantageous to plant growth. The best time to fertilize is in the morning or evening, but not at noon. When fertilizing, try to pour slowly along the edge of the basin or away from the soil, so as to reduce the damage of fertilizer to plants.

In fact, it's not weird, we don't directly bake the embryo of the seed, but the shell of the seed, so the part of the seed that can really store genetic information is not destroyed. On the contrary, it is a kind of stimulation and catalysis to mallow. So not everything that seems dangerous is really dangerous.
