How to cultivate Carthamus tinctorius Culture methods and matters needing attention

Saffron is a kind of flower with great ornamental value, it is generally common in our lives, like to grow in a warm environment, but should not be directly exposed to the sun. Now there are a lot of people raising saffron, but before breeding, most people must want to know more about its breeding skills.

How to grow lipstick

1. Soil. Choose saffron like acidic soil, so it is best to choose slightly acidic potted soil, peat soil, sand and vermiculite can be selected to prepare culture soil. An appropriate amount of calcium phosphate can be added to the soil. Or choose rotten leaf soil and coarse sand according to the proportion of 8:2, and then add a small amount of mature animal manure or compound fertilizer for cultivation.

2. Temperature. The growth temperature of saffron is 18-30 ℃, and the optimum temperature is about 25 ℃. Its cold tolerance is relatively poor, and the overwintering temperature is above 12 ℃. It is necessary to keep the potted plants indoors in time in winter and avoid direct blowing by cold wind.

3. Light. Red orchids like to grow in a semi-overcast environment. In addition to the strong light at noon in midsummer, adequate light should be given at other times of the year. If the leaves of saffron turn red during maintenance, it is mainly because the room temperature is too low or the light is too strong, then you need to increase the room temperature in time. It is easy to cause if the temperature is too low for a long time. The phenomenon of leaves falling off and branches drying up.

Culture methods and matters needing attention of Crocus sativus

1. Culture methods:

1, fertilization: Carthamus tinctorius needs less fertilizer at ordinary times, apply some rotten liquid fertilizer every two weeks, it is better to be sparse than thick. When putting on the basin, add an appropriate amount of livestock hoof horns and broken bone pieces as base fertilizer to make it grow well. During the peak growth period of Carthamus tinctorius, mature organic fertilizer solution is applied once every 15-20 days, and after summer, more phosphorus and potassium fertilizers are applied, such as 0.1% solution of potassium dihydrogen phosphate and 20 times the solution of rotten fish visceral water and bone water.

2. Watering. The growing period of Carthamus tinctorius is from March to September every year, and the temperature is higher during this period, and the water demand of the plant is larger, so it needs to be watered or sprayed frequently to increase the air humidity. Open windows as often as possible in summer. After autumn, the amount of water gradually decreased to improve the cold resistance of the plant.

2. points for attention:

Red orchids like to grow in a semi-overcast environment. In addition to the strong light at noon in midsummer, adequate light should be given at other times of the year. If the leaves of saffron turn red during maintenance, it is mainly because the room temperature is too low or the light is too strong, then you need to increase the room temperature in time. It is easy to cause if the temperature is too low for a long time. The phenomenon of leaves falling off and branches drying up.

What if the leaves of saffron turn yellow?

1. The temperature is too low. Solution: if it is found that the leaves turn yellow, the room temperature should be raised in time, and cold protection measures should be taken. The flowers can be covered with plastic film and breathable regularly. Wait until the temperature returns to the right temperature before removing the film.

2. Watering too often. Solution: immediately stop watering, remove the basin soil for ventilation and cut off the rotten roots to spray carbendazim. Watering should grasp the principle of "dry and wet" and do not water too frequently.

3. Lack of light. Solution: you should set aside free time every day to put the orchid in the sun for a few hours, but not too much exposure to the sun.

What if the lipstick loses its leaves in winter

1. If the roots continue to lose the leaves, it may be that there is something wrong with the roots. It may be that the leaves are usually watered too much or die without watering, then the leaves will begin to fall in a large area. Once it is serious, it will directly let it die, so be sure to see if it is broken, and timely transplant treatment is necessary.

2. Caused by too much light. Lipstick itself likes bright and sunny places, although it likes the sun, it can only accept 2 to 3 hours of care every day, not for too long. Some friends think that making it grow better will make it like other plants. Basking in the sun for a long time will be counterproductive. Therefore, the light time can not be too long, it can adapt to the semi-overcast environment.

The culture method of saffron is relatively simple, as long as the temperature and light are controlled. Proper control of fertilizer and water is also needed in aquaculture, and only by doing a good job can we ensure the healthy growth of saffron.
