How often is the cactus watered? What are the methods? How to manage the seedling stage?

Cactus is a spherical succulent plant of the cactus family, there are many varieties. Cactus is a kind of plant with high ornamental value in spherical stem, thorn and flower. How often is the cactus watered? What are the sowing methods of cactus? What is the management of cactus at seedling stage?

How often is the cactus watered?

1. Look at the planting time. Just bought cactus can not rush to water, first let the soil slightly moist, wait for the cactus to adapt to the new growth environment, and then gradually increase the amount of water, otherwise it will only increase the burden.

2. Look at the seasonal changes. Spring and autumn is the vigorous growth period of cactus, which should be watered once a week; water evaporates quickly in summer and should be watered every 2-3 days; winter is its dormant period, so it is best not to water it again.

3. Look at the placement. If the cactus is placed outside, the water will dry quickly and the watering frequency will be higher than that of the indoor cactus, but only if the basin soil is watered thoroughly and there is no stagnant water at the bottom of the basin.

Second, the sowing method of cactus

1. Before sowing cactus seeds, we should first prepare containers and cultivation media. The sowing pot is not easy to be too large, so it is appropriate to sow all the seeds, and some can use disposable cups with holes.

2. The soil should be well drained, the soil for sowing should not be too fertile, the soil for growing vegetables should not be used, and the soil in the flower bed should not be used. I use broken red jade soil. I have used peat and pearl before, and sand can be used if there are no conditions, but I have to transplant it after 3 months. 、

3. Put the soil into a basin and disinfect it in the microwave oven for 5 minutes to kill fungi and parasite eggs.

4. Prepare the seeds for sowing. If there are conditions at home, it is best to soak the seeds with potassium permanganate (carbendazim) the day before yesterday. If there is no potassium permanganate in my house, we will not soak. When sowing, put the seeds on the soil, make sure the spacing is not too tight, then sprinkle the soil to cover the seeds or gently push the seeds into the soil.

5, then spray some water, be sure to cover the transparent plate to moisturize, put it in the place of scattered light, the seedlings come out to bask in a little sun, do not expose to the sun, the seedlings turn green with more light, purple red with less light, and light red is the best.

6, this is fine, seed germination varies from 3 days to several months, depending on the temperature and humidity of the species, so do not rush to throw away those that have not germinated, and some seeds need to wait patiently for a long time to germinate.

III. Management of cactus at seedling stage

1. Lighting

After a week of emergence, the amount of light can be gradually increased, and half a year later, full sunshine management can be carried out. At this time, we still need stuffy culture, and we can remove the film management after a year. After removing the film, we can not immediately stay in the strong light for a long time, and we need to slowly adapt to the light intensity. Of course, it is OK not to sulk after emergence, but the growth rate is slow.

2. Moisture control

Remember that Miao is not afraid of water, but he can't stay in an excessively humid environment for a long time. It is found that due to timely replenishment of water after the topsoil is dry, it is best to use the immersion basin water supply method for hairy cactus.

3. Sterilization and disinfection

Later management should also pay attention to sterilization and disinfection, combined with rehydration, once a month in the first three months, and the interval can be increased later. If the soil water supply is not needed, it can be sprayed directly and evenly.

4. Fertilization

With this kind of soil, the seedlings do not need to apply fertilizer within a year. If the hands are really itchy, it is recommended to apply thin night fertilizer.
