The Carnegiea gigantea requires very little maintenance, but it does benefit from some fertilizer every spring and summer to keep it healthy and thriving. This type of fertilizer comes in granular form and should be applied directly to the roots of the Carnegiea gigantea once every 3-to 4 weeks during the growing season between April and August. During winter, you will not need to fertilize your Carnegiea gigantea. In fact, you should not fertilize your Carnegiea gigantea in its first year after repotting.

Types of Fertilizer for Saguaro Cactus
Houseplant fertilizers are available in liquid, granular, and slow-release formulas. It’s also possible to purchase worm castings as a nutritional supplement. Each kind has both advantages and disadvantages.
Liquid- Liquid fertilizers are the easiest to use and most popular with saguaro owners. They come in spray bottles or concentrated formulas that have to be diluted before use. Liquid fertilizers release nutrients instantly, so they should be applied at least once a week, preferably more often when the plant is actively growing.
Liquid fertilizer is available in several different forms:
- In concentrate forms in many different sizes from gallon jugs to small bottles that contain enough nutrients to feed your cactus for a month or more.
- As a spray bottle with concentrated formula inside.
- As a premixed spray bottle.
Granular- One of the most common types of fertilizer for saguaro cactus is granular. Granular fertilizers are available in various formulas and concentrations, with one of the most popular being a 10-10-10 formula. These fertilizers have been shown to be effective on all types of plants, including cacti, and can be easily applied.
Fertilizers are affordable and easy to use, simply requiring the user to mix them into the soil. They should be reapplied every 4 to 6 weeks.
Slow-release- Slow-release fertilizers are a convenient way to nourish your lawn. They come in many different forms, from pellets, balls, spikes, and capsules. As their name suggests, slow-release fertilizers break down slowly over time, and some can last up to 9 months. They’re a good choice if you don’t want to have to remember to spread fertilizer every month or two.
A downside of slow-release formulas is that they provide the user with less control over the rate of fertilizer release. If the coating on the granules cracks or dissolves too quickly, then too much fertilizer could be released at once. Overfertilization can lead to yellowing leaves and other problems.
Worm castings- act as a natural fertilizer that contains key nutrients like carbon, calcium, nitrogen, and magnesium. They also act as a pH amendment, helping the soil to absorb nutrients more readily.
Organic fertilizers are made from a combination of natural ingredients, such as animal manures, agricultural residues, and plant materials. They might also contain inorganic ingredients like peat and rock phosphate.
In addition to providing nutrients to plants, organic fertilizers are often used to amend soil conditions and improve soil structure by increasing water retention, aeration, and drainage. Organic fertilizers break down over time, so they must be reapplied to maintain the desired level of nutrients in the soil.
Organic fertilizers generally tend to release nutrients over time and might not produce instant results. One downside of organic fertilizers is that they may have an unpleasant smell.
Inorganic fertilizers- Inorganic fertilizers are a popular choice among growers and gardeners. Manufactured in a lab, inorganic fertilizers are composed of man-made ingredients that are sometimes derived from natural sources. They are formulated to meet the unique needs of a variety of plants, but they contain chemicals that increase their nutrient density. The synthetic nature of inorganic fertilizer lends itself to the easy application and odorless results.
Buying Guide To Juicy Fertilizers
When you’re a new gardener, it’s easy to be tempted by the enticing descriptions on a bottle of fertilizer. And if you’re someone who doesn’t have a lot of time to research, you may also count on the manufacturer’s promises and instructions to give you that extra push. This guide will help you determine what’s really important in fertilizer. Read on what we need to decide before buying fertilizers
Obviously, fertilizers can be bought in liquid and solid forms. In addition, liquid fertilizers can also include foam and spray types, while solid fertilizers consist of capsules and granules. For the latter, all you have to do is sprinkle them around the soil and mix them lightly with the first 5 cm of topsoil.
The NPK ratio is the ratio of three major nutrients: nitrogen (N), phosphorus (P), and potassium (K). This ratio is important for maintaining the health of your plants, as these nutrients are essential for growth. If there is too much of one nutrient and not enough of another, a deficiency may occur. A balanced NPK ratio like 2-2-2 is ideal for full growth.
Fertilizer vs. Plant Food
Fertilizers and plant foods are different in that fertilizers provide nitrogen, phosphorus, and potassium (NPK), but whole plant foods do not. Plant-based foods are preferred for strains that lack the essential micronutrients beneficial for growth. Alternatively, fertilizers provide the plant with an adequate amount of nitrogen, phosphorus, and potassium.
