How to water a cactus

Watering time

The time to water cacti depends on the season. In summer, because the weather is hot, it is best to water them in the early morning.

Watering in winter should be done during the warm noon to reduce the difference between water temperature and air temperature and ensure the growth temperature of the plants.

Watering in spring and autumn can be done in the morning or in the evening.

Amount of watering

When watering the cactus in spring and autumn, just water it enough, that is, the soil in the pot should be moist. Do not water it if it is not dry.

Note that in summer, due to the high temperature and heat, you must water the plant sufficiently in this season. Not only should the soil in the pot be moist, but you should also spray water around the soil frequently.

In winter, watering should be controlled to keep the soil slightly dry, or no watering should be done at all.

Be careful not to water plants that have just been repotted, or newly planted cacti.

How to fertilize cactus

First of all, appropriate fertilizer should be applied during the growth period. The fertilizer can be decomposed thick liquid fertilizer, and it should be applied once every 15 days or so.

After entering autumn, you should pay attention to controlling fertilizer and water. It is only necessary to apply it once a month to control the growth of cactus branches and prevent it from freezing to death in winter.

Secondly, when applying fertilizer, be careful not to let the fertilizer splash onto the ball;

When potting or repotting, apply base fertilizer at the bottom of the pot, such as decomposed oil cake, bone meal, etc.; in the later stage, topdressing should be applied according to the growth of the plant, and decomposed feather hoof horns, etc. can be used, and it should be added every two weeks.

Also, be careful not to use concentrated fertilizers or raw fertilizers. Fertilizers can be mixed with other solutions and applied alternately. The amount of fertilizer and water should only cover the surface of the soil in the pot.
