The Best Fertilizer for Cactus and Succulents

The majority of cacti and succulents fall under the category of arid plants used to surviving in environments with extreme temperatures and little rainfall. While the succulent can be in hot and cold climates depending on its species, cacti are almost exclusive to deserts. Both plants require a specific type of soil designed to be well-draining, filled with the right nutrients, and light enough to allow the roots to grow deep. Also, cactus fertilizer is necessary to grow healthy plants.

When it comes to identifying the best fertilizer for cacti and succulents, you might have some questions. Each product claims to be the best, but it is impossible for all of them to be. With this in mind, we have identified the top five options currently on the market. We’ve also included a handy buying guide so you know what to look for when trying to find the best soil for your garden or potted plants. 

Cactus Fertilizer: What to Look For

Succulents and cacti need a unique mixture of soil to remain healthy. Plus, because each species is different, some will have slightly different requirements than others. In general, you should choose a mixture which meets the following requirements: well-draining, arid, filled with sand and gravel, and between 40 and 80% nutrition. 


Drainage refers to how much moisture is absorbed and kept by the soil when it is watered. Cacti and succulents need to be planted in a potting mix which consists of lighter material such as sand, gravel, and other small, hard substances. These do not become tightly packed and allow water and moisture to filter through. The soil pulls just enough liquid to keep the roots of succulents and other plants satisfied. Excess is removed so the plant does not drown or become susceptible to root rot. 

Cactus Fertilizer: What to Look For

Arid and filled with sand and gravel are related to the required drainage property of the soil. However, they also add other benefits. Succulents and cacti draw many of their nutrients from their environment and are designed to live in nutrient-poor areas that necessitate maximum root growth. 

How Often Should You Water?

Succulents and cacti need little water to remain happy and healthy. It is recommended you only give your plants water every 7 to 10 days. Although the cacti and succulents can survive with less water, it is a poor idea to restrict liquid during the growing season of spring through fall. 

Cactus Fertilizer: Nutrition

Like many other plants, cacti and succulents need a combination of nitrogen, phosphorus, and potassium. For these types of plants, nitrogen is the most important element necessary to keep them happy. It is important to find soil and fertilizer that has plenty. Avoid using too much filler like wood chips, beads of white cactus fertilizer, or loamy and heavy soil. 

Picking a mixture that includes some peat moss is also an excellent idea. Although some gardeners consider it to be a filler, peat moss can create a great environment for roots to grow. For those that don’t know, peat moss is a combination of 380 different mosses which are mixed and blended together to create a source of nutrition and decomposing soil for other plants.

How Often Should You Fertilize?

Because of their nature, cacti and succulents need little extra cactus fertilizer to be satisfied. If you are interested in adding extra nutrition for your plants, limit it to a small application every two to three months.

Neutral pH

Finally, it’s important to check the pH of the potting mix. Cacti and succulents, as well as many other plants, work best when planted in neutral soil. On the pH scale, neutral is typically anywhere from 6 to 8. The lower the number, the more acidic a substance is. Higher numbers are basic. If you are struggling to locate a neutral potting mix, it is better to use an option that is slightly acidic rather than basic.

What kind of fertilizer should I use for cactus?

Cacti are not like other plants where they require high levels of nutrients and water. They survive on only a little bit of food. However, they still require a good amount of water and fertilizer to make them grow strong.

The best type of fertilizer for cacti is one that has a low pH level. The best time to apply this type of fertilizer is when the cactus is in its dormant stage (the time when it doesn't need more nutrients).

Is cactus fertilizer good for succulents?

From my research, I found that it is pretty safe to use a variety of cactus fertilizers with succulents. Cactus fertilizers typically contain organic matter that provides nitrogen, phosphorous, and potassium in addition to trace minerals such as iron and magnesium.

I think some plants might not grow well if they have too much or too little of these nutrients. So depending on the plant species you want to grow, you should use a certain type of cactus fertilizer with them.

Cactus fertilizer is a product that comes in powder form and works by releasing nutrients into the soil via the water that it evaporates when applied to the plant. It's often recommended as an alternative to soil or potting mix, but like most fertilizers, you should test out your soil before applying it so that you know what your plant needs.

Do succulents need special fertilizer?

The answer is no. Succulents don’t need any special fertilizer because they are not plants that need to be watered or fertilized regularly.

Succulents have a unique ability to store water in their leaves and stems and they use this water when they need it. They can survive without fertilizers, but succulent enthusiasts often use naturally occurring minerals such as soil, sand and pebbles to help them thrive in the right environment.

How often should you water a cactus?

Cacti are one of those rare plants that require a lot of attention to survive. They do not like being touched or having their soil disturbed, so it is best to leave them alone as much as possible. If you have a cactus make sure you water them every 2-3 days.

In general, the cactus needs about 1-2 inches of water a week. You should check how much soil is exposed with your finger and give them enough water to keep them alive and well-conditioned..

When should I fertilize my succulents?

The answer to this question is quite simple - it depends on the succulent type.

It is best to fertilize succulents according to their need and condition. If they are thriving, then you should water them more often and give them more nutrients. If they are not doing too well then you should water them less often and use less nutrients.

Succulents can be divided into two groups: hardy succulents vs tender succulents. Hardy plants have tough leaves that can withstand a lot of wear and tear, but tend to have shorter lives than tender plants which usually have thinner leaves that are prone to rotting in harsh conditions.
