If you are one of the curious individuals who want to grow and care for a cactus plant, you’ve come to the right place. Here at Eden Succulents, we will be discussing the answer to the question “How often do you water a cactus?” If you want to know more information, make sure to continue reading below!

A cactus plant is a succulent. Like most succulent plants, a cactus plant needs specific care to live and grow healthy. Cacti belong to the family of plants called Cactaceae. The name cactus comes from the Latin word “kaktos” which means a spiny plant whose identity is uncertain.

Cacti are succulents, but not all succulents are cacti. This means cacti have fleshy, thickened stems that are effective in storing water. Cacti are native to the Americas and some can live in the driest deserts and arid areas, with extremely dry climates. Most cacti have spines which are modified leaves, effectively defending the plant from predators and its stems carry out the process of photosynthesis.

How Often Do You Water a Cactus?

Most individuals think that succulents require only a small amount of water to survive, that thinking is wrong. Yes, succulents are a type of plant that can thrive with a small amount of water but it will depend on the circumstances and its growing conditions.

During the growing season, cacti just like other plants need regular watering. Most plants grow during springtime until fall. Most plants will stop growing during the colder months and they will undergo winter dormancy.

While your cacti plant is growing, it should be watered once a week, although some plant lovers’ water more often. Important reminder: when watering the cacti, you must give the soil a good soaking. Allow the water to flow out of the drainage holes of the container and drain the soil of any excess water that can cause the plant to become prone to rot. You must use a terracotta container with drainage holes, you can get yours here. This will help improve the draining ability of the soil. You must also use a well-draining soil – make sure to use a succulent/cactus soil mix like this.

When the weather becomes cooler and the days become shorter, the cacti plants may enter a rest period. You can increase the interval or frequency of watering. You must always remember to allow the soil to become thoroughly dry before watering again. During a cacti’s dormancy period, you must provide enough water so they will not wither, shrivel, or become dry. You must treat your cacti different from your other plants as some cacti plants still grow even during wintertime. You can ask your local cacti or succulent nursery for your cacti plants’ growth habits.

When watering your cactus plant, there are a few things to take note of. Tap water may contain dissolved minerals, and it can be alkaline or hard which can build up in the soil of the plant over time, and this can cause harm to your plant. Make sure to repot your cacti every couple of years so you can remove old potting soil that has built up minerals in it. Do not use water that has been treated using the softening system as it often uses salt as a recharging agent and this can increase the sodium content on the water. This can be quite harmful to your cacti plant. If you have access to rainwater, you can collect, store, and use it to water your cacti.

Cacti plants in pots or containers may need more watering than those planted directly in the ground. You must also watch for any signs that the stem or leaves of the cactus plant are becoming stressed because of a lack of moisture. An under-watered cactus will look skinny, pale, withered, and shriveled.

How often do you have to water your cactus plant? Here are some tips to help you determine how often to water it.

How often do you have to water your cactus plant?

Does the cactus have leaves or stems?

Most cacti species do not have true leaves. When a cactus has thin leaves, it will need more water.

Does the cacti have spines?

If a cactus has spines, it will need less water than a cactus with a few spines. Spines are considered as modified leaves. Spines do not contain water and will help a cactus conserve water by trapping air on the surface, which, therefore, creates an insulating layer that prevents rapid evaporation and transpiration. The spines of the cactus plant also help lower the plant’s temperature and decrease water loss. Spines are also effective in capturing moisture from the atmosphere.

Does it have a thick and fleshy stem?

If a cactus has a thick stem, it will help conserve water. The stem of a cactus will help store water. A cactus with a round shape or cylinder shape will store water effectively. If the stem of the cactus is ribbed, it will be able to adjust according to the increase and decrease of water content.

Size of the cactus

A smaller cactus plant will need less water than a larger one. A younger cactus that is growing will require and use more water. Large cacti will have a smaller surface area to volume ratio and can effectively decrease the evaporation rate of the water from the plant. Smaller and fast-growing cacti in small pots or containers will need more watering and attention.

Temperature and Humidity

If you live in areas with warmer climates, it will increase the evaporation rate of water from your cactus plant and the surface of the soil. Higher temperatures will also mean that the cacti will be growing and using more water in the process.

You must also check for the airflow because increased airflow in the area will also increase the evaporation rate of water from the plant and the soil surface. When the cactus plant is placed outdoors, airflow is much higher, so therefore, you must increase the frequency of watering accordingly.

The humidity will also affect the watering conditions of a cactus plant. Evaporation levels will increase when the area has increased humidity. The wet potting mix will dry faster. Cactus plants do better in arid and dry conditions. Make sure to monitor the dryness of the soil so you will know how often you will need to water your cactus plant.

Frequently Asked Questions

Question: How Do Cacti Live Without Water?

Answer: A cactus plant cannot survive and thrive without water. A cactus, like other succulents, are designed to survive for long periods of drought. It has thick stems that hold water inside; it does not have leaves so it does not give up its water content through evaporation, unlike other plants. Because of its thickened stems, it has a lot of room to store water and it has a protective covering that helps the plant to keep the water inside.

Answer: Cacti will die and wither if exposed to too much water. You must allow the soil of the plant to dry out in between watering. The top few inches of the soil must be thoroughly dry. Usually, plants will need less watering during wintertime, and cacti plants are not an exception to that rule.

A cactus plant can be watered once a month or less during wintertime. Never allow the roots of the cactus to sit in standing water.

Just remember to use a pot or container that has drainage holes and allow the water to drain properly every time you water the cactus plant.

Cacti are popular among plant lovers because they need little to no maintenance. They can be the easiest plants to grow but you must always remember not to water them too much. An overwatered cactus is prone to root and stem rot. Yes, too much water can kill them. An overwatered cactus plant usually shows increased growth and signs of good health during the beginning.
